I overlooked that! Only the 2791/93 has an *internal* clock divider circuit needed when you control either 5.25" or 8" drives. For the 2795/97 this means additional external circuitry. I have in my design an octal latch to control some things, so density can be controlled with one bit from the latch. All in all, I will make my design with the (available) 1793. I only have *one* trimpot adjustment, the 279x has *two*. I will take the +12 from the power supply. The 7660 is a good suggestion, but increases the chip count by one, unnecessary. Ok, one wire added instead :-) BTW, my design should work with 8", 5.25", and 3" proven years ago, so I expect that 3.5" will work too ... time to heat up the soldering iron! thanks, - Henk, PA8PDP.

I'm trying to troubleshoot a problem on one I just got, a Series II, model 225. There is a large PC board on the back panel of these beasts called an IOC (Input/Output Controller). It contains an 8080 cpu, some ram, some rom, and basically all the I/O for the machine on the back panel. It is commanded by the system's cpu (a different board plugged into the front multibus chassis) through a couple of I/O ports, if I remember correctly. The IOC board has a three-position switch on the back. One position is "line" and in that position it is connected to the system cpu and does its everyday work of controlling the I/O for the MDS. One position is "local" and in that position I think all it does is echo characters typed on the keyboard to the crt. The third position, "diagnostic" causes it to run some internal confidence test. In that position, if everything is healthy, there are a series of two beeps, a pause, then three beeps after reset. After that there are some choices on the crt that let you run a few different tests from the keyboard. The one I'm working on will beep twice, then pause, then only one beep. Nothing further happens. No characters on the crt (which does have a raster, so at least part of the crt-controller function of the IOC is working), no apparent response to keyboard typeins. My question is this...does anyone know what part of the diagnostic is failing when there are only three beeps instead of five? The documentation I have only says it should beep five times but doesn't say what each beep signifies. It would help narrow down my search for the problem if I know what part of the test is failing. I'd love a disassembly of the firmware of that board, but I've never seen it or any source for it. That would be very helpful. Anyone have such a thing? I don't remember ever seeing anything like that from Intel, but it was a long time ago and I may have just forgotten. I'll be diving into this problem this weekend, but if anyone can help with the above couple of questions that would be wonderful. Thanks in advance!

My second thought is SCANBE. My third thought is... can you guess? Replacing the SCANBE sockets with AUGAT barrel type on the older IOC's has always solved my 5 beep test problems. Making sure all socketed components are properly seated in reliable sockets. The manuals, flow charts, etc... all say to replace the IOC if the 5 beeps test fails. The manual called: Customer Engineer Diagnostic System Test Operating Instructions For Series II Systems (121619-001) may break down the 5 beep test, but I do not have a copy. Tips for replacing the SCANBE sockets. 1. Pull the plastic housing of the SCANBE socket off the board. 2. Remove the mylar sheet from between the pins. 3. On the component side grab one of the pins with needle nose pliers while heating same pin on the solder side, pull to remove. Repeat for all pins. 4. Use solder wick to remove solder from holes and clean up. 5. Clean area with flux-off if needed. 6. Install AUGAT machine barrel socket. 7. Clean area with flux-off.

I'd like to tell my update on the SIMH blinkenlight console project(s). A year ago (or so), Vince and I developed the 6809 Core and I/O Boards. To refresh your memory about this project: the 6809 Core Board runs an application that communicates with a modified PDP-11 version of SIMH. You connect the I/O Board to switches and LEDs that represent a PDP-11 console, in my project example an 11/40 console. This console is the part that you had to do yourself, you could/can take a real console, but as I said earlier, that's (perhaps) a waste of a good machine. For this project, see www.pdp-11.nl/homebrew/startframe.html I have a new application that takes the first project one step further. The 6809 now simulates the PDP8 instruction set, and the I/O Board simulates a complete pdp8/e console. See this project results on : www.pdp-11.nl/homebrew/pdp8/pdp8startpage.html Especially the second "project" is nice (IMHO). I can run SpaceWar in OS/8 on the 6809 ! During the workz I added an IDE hard disk interface to the I/O Board! The pdp8/e simulation boots DMS or OS/8 from the CompactFlash card. As the performance is not *that* good (...), I upgraded the Core Board to run twice as fast. You can do that upgrade too, if you have installed the 6809, 6850, and 6821 in sockets. Replace these 3 chips with their "B" version, and replace the 4 MHz clock with an 8 MHz version. That's all! The RAM chip(s) and the EPROM that was delivered in the kit are fast enough to support this upgrade. The initial load of the pdp8 software is not "user friendly". I am thinking about a Floppy Expansion Board (FEB) that connects to the Core Board through the PIA socket. The 68(B)21 is installed on the FEB. The FEB has all parts to connect 2 or 3 floppy disk drives, which can be 8", 5.25", 3.5" or 3". I will test the 3.5" version, but expect the other drives sizes to operate corretly too. The controller will be the 1793. I intend to write the floppy disk drivers in the monitor, so you can use the floppy disk also in the 6809 environment. From my hobby 20+ years ago I have a self-written DOS, not compatible with FAT-12. Sorry, the PC was just 1 or 2 years old when I wrote that DOS. However, "my DOS" has all the commands you'd expect. I can make the FEB just for myself, but if there is more interest on this follow-up project, I will document this work-in-progress better than I'd do just for myself ... An other thing I am thinking about, is a new design of the Core Board to get a better performance for the pdp8/e simulation. I am looking into the possibility what speed improvements this sim would get if I rewrote the 6809 pdp8/e code into 68000. The new Core Board will of course have an 68000 (or cost reducing) 68008 clocked at 10 MHz. Any comment is welcome, but I will ignore proposals for CPLD, Atmel, etc. enjoy the pdp8/e simulation webpage! - Henk, PA8PDP. what's in a callsign :-) From acme_ent at bellsouth.net Thu Sep 1 16:37:14 2005 From: acme_ent at bellsouth.net (Glen Goodwin) Date: Thu, 01 Sep 2005 17:37:14 -0400 Subject: Archives & DECmate Message-ID: <4317748A.8010409@bellsouth.net> A few months ago there was a discussion on the list about the DECmate.

I can't remember if the context was bank checks or punched cards, (probably the latter), but way back in the past I remember seeing a machine that would slowly feed such a document between a pair of rollers. The rollers had a pattern in them not unlike a cutter that would be used to produce a crosshatched knurling pattern on a tool handle, but the pattern was not as deep. They used substantial pressure and would straighten the subject document right smartly. Fingers too, no doubt.

I mean, who And circa-1970-or-so one could say the same about 400 series accounting machines as they headed to the scrapper. :) Actually, two years ago I passed up an opportunity for a full-size vac-col 7-track tape drive of 60s vintage. I wouldn't have minded too much it occupying some space but I really did not relish the thought of dragging it around to whatever space it was going to occupy. Had been in a garage or basement for a couple of decades and the vacuum pump had been pilfered. The guy who took it to the scrap dealer got $100-$200 for the aluminum. I'm left with the copper-clad head assembly and a tape position sensor from a vacuum column. Didn't find out the model or manufacturer, although the circuit boards were made from the pale-yellow phenolic material like that of IBM SMS cards of the late-50s/early-60s. It would have been fun to RE it, make a controller and interface it to something to make it functional. ("Couldn't be that difficult, could it?", he said in ignorance.)

I'm not sure I see the problem. It's impossible to know if the machines they were taken from were operational. Breaking devices up for spare parts, in such a way that the spare parts are indeed functional subsystems, is a perfectly good way of recycling otherwise useless stuff. That applies to cars, it applies to computers. For example the first item: it's not bits of printer chain suitable only for hanging on the wall, it appears to be a useable printer chain assembly ready to load into your printer. And yes, quite often parts are more valuable than the whole system.

IBM card readers tend to be more demanding, since they (at least the ones I know) push the card into the reader by its far edge. This is done with a chunk of metal that has a step on it whose height matches the card thickness. Most other card readers (for example the DEC/Documation ones) use a vacuum pick. The card is grabbed near its leading edge with a rubber-coated devices that has holes in it leading to a vacuum pump. So long as the leading edge isn't badly mangled, or you hand it two cards stapled together, this scheme is very forgiving of bent cards. paul From pkoning at equallogic.com Fri Sep 2 08:55:12 2005 From: pkoning at equallogic.com (Paul Koning) Date: Fri, 2 Sep 2005 09:55:12 -0400 Subject: Anybody live in Chile?

CDC came out with the Hawk, I think (all their drives were birds then) and which was an 8" drive, and it had 20mb, 20mb on each side of a platter. I don't recall the name, but they also had a removable cartidge type drive with a single platter as well. An 8" drive which was not ANSI interfaced or SMD interface would have been unusual. I don't know if PDP8's ever had an interface to SMD other than maybe odd knockoff vendors. The 14" drive they used would have had RF from the heads on the interface cable, and a servo signal doing the seek, rather than the SMD drives later use of an address on the cable, and ANSI's attempt to get rid of both RF for the data, and going to a sort of protocol similar to scsi. Infomag sold positioners to Microdata, who had drives of both the type mentioned above, as well as a winchester design. There was also other Southern California drive makers who used them as well. I belive that Priam used them in their drives, as well as some up in the valley, such as Micropolis. It is interesting that the media coating on the platter seems to be silver in color, so the media may have been metal plated, rather than oxide coated. I could not tell much from the photo quality about that. some magna-see on the surface would be interesting, as you could then measure the track spacing Jim "A. G.

This is all obsolete stuff. The entire units would be better than the parts shown in the auctions, assuming they were available. If the stash comes from spares, then it is forgivable, but too many of these are hacked off working machines, and put up for sale only then by scrappers. I have had direct experience with at least two, who I educated and purchased stuff from. They simply don't know. I did recieve a reply from the guy about the Basic 4 front panel, which is for a Microdata 1600 (do you read this stuff Jay?) and he does not have any other parts but a blue Basic 4 badged printer, probably a data products B150 or B300. there are two guys I have purchased from on ebay who have spares in the US, who were not scrappers. but there are a couple of others who should have known better.

The old drives were the ones I had to deal with the most. It was a COM facility so the only thing we ever did was read tapes, but they came from all over the place (different customers). Also, it was only the NEWEST drive that had 6250 bpi. Mostly we dealt with 800 and 1600 tapes, and with drives that had switchable 7/9 track heads.

They were not dual-ported, though, you only had one address bus for both reading and writing. You could link these pins together externally, or you could use them separately. IIRC on the IBM PC, the DIN and DOUT pins are linked on the RAMs storing data bits, but wired separately on the RAMs storting the parity bits. I think SIMMs brought the pins out separately so that you could use them separately if you wanted to, or just link them together on the SIMM socket. If you have the machines that are supposed to use these 64 pin SIMMs, can you not just check to see if DIN and DOUT are linked on the mainboard with an ohmmeter? -tony From ard at p850ug1.demon.co.uk Fri Sep 2 18:27:19 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Sat, 3 Sep 2005 00:27:19 +0100 (BST) Subject: Intel MDS Series II IOC question In-Reply-To: <20050901130640.S99592@racsys.rachors.com> from "George L.

I've never seriously looked at the IBM channel, but the DX11, the Unibus -> IBM Channel interface, is 8 rows of M-series flip-chip cards, plus a power control chassis + a PSU. And that only does the 'peripheral' side of the interface, it can't be the 'master' (if that's the term).

Judging from the S/3 Mod 15 docs (the big S/3s had a bus and tag channel for a DASD), bus and tag is not completely weird, and could be implemented without too much trouble. It is not fast, by today's (or even yesterday's) standard. The drivers and receivers might be a little bit of a hassle, unless some were chopped out of an existing IBM.

The 3803 will do quite a bit of things - but yes, without a bus and tag equipped processor, not much happens. The small ES/9000 (the 9221), or an S/390, can use a 3480 system.

The Axxx and Wxxx stuff looks more interesting. None of it is anything I particularly need (looks like the non-generic stuff is more -11 than -8). I suspect you could get a few dollars each for them one at a time on ePay, or rather less as a lot. My own ePay rule of thumb is about $5 each for an Mxxx flip-chip module spare. If it is something I specifically need, I'll pay more. Gxxx and other modules are often specific to a particular device, so I am willing to pay more (assuming it's a device relevant to my collection).

References: Message-ID: <008e01c5b03d$4769d920$0500fea9@game> Today I got a Mac Nubus card in the mail and was told it was a Tokamac Accelerator. The Card has written on it : Donoho Design Group, Inc Copyright 1992 PN: 04-106 with a hand written paper tag on the back (219-2525-360). Its a full length card with 2 connectors (NUBUS and PDS inline). The card fits in my IIfx perfectly. Besides the 68040/33 processor there are 3 chips labeled "Toruc", "Nexus", "Fusor" on the card (xilinx xc 3030-100 type chips). If this card the Tokamac IIfx or do I have something else? If so where can I find drivers for this beast (havn't had any luck so far with google and old Mac driver sites). Cards of this vintage are usualy hard to find drivers for, any old Mac packrats here? Sincs its from 1992 and not a common part I assume its ontopic to ask about it.

When I made up a channel adapter (that is, to connect to a CPU) I used TTL (probably LSTTL), with 374 Tristate Tx and 244 Rx. This worked, but maybe didn't meet the official spec. I think you can find a spec on Bitsavers, A22-6843-3. This gives >2.25V for 1 and <0.15V for 0. >From a higher-level perspective, the channel is not unlike SCSI. Making a channel which would work with a specific I/O device wouldn't be too difficult.

This is the at top of my list. It's going to be a USB-2 channel driver (talks to peripherals). Have the design done but have't started building it. Immediate goal is testing of channel interfaced devices to help cull the collection of big iron, secondary goal is operation of the devices from Hercules. Speaking of USB-to-X interfaces, where X is pecular, thanks, Sellam for the plug for my USB-to-Documation interface. I'm thinking of building two more copies, another for me and another for the museum. Is anyone else interested in one? If so I'll do up a PC board instead of wire-wrapping, and we can share the production cost. Let me know by private email. PS - APL\1130 was mentioned recently. We have the source on punched cards. I've read it in but there were a couple of errors which is why it's not published on ibm1130.org yet. Also, it appears to have been modified (slightly) to run on the IBM 1800. brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel _| _| _| Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 _| _| _| Fax: 1-510-525-6889 _| _| _| Email: brian at quarterbyte.com _| _| _| http://www.quarterbyte.com From kth at srv.net Sat Sep 3 13:29:37 2005 From: kth at srv.net (Kevin Handy) Date: Sat, 03 Sep 2005 12:29:37 -0600 Subject: VT220 symptom In-Reply-To: References: Message-ID: <4319EB91.4020704@srv.net> 9000 VAX wrote: >Hi, list, > My VT220 went crazy yestoday.

DEC used lousy flyback transformers, and they were always my biggest problem with all the VT terminals. They would short out (cracking the ceramic shell and oozing black goo that would then harden), and often taking out a driver transister too. You can repair this problem with a new flyback (probably going to be hard to find), and a new transister. Been there, done that (many times), got the T-shirt.

I just don't happen to have the right manual that describes that diagnostic. I believe it existed but was mainly for the repair techs. I have lots of good docs, as you well know, and as you do also, but it seems that we might both be lacking the particular one I need. I was able to get in touch with one of my old buddies who was an Intel repair tech. He said that at one time he had the source code for the firmware in that IOC board. Boy! I would like to have a copy of that, but he didn't keep it and is retired. Unlike me, he HAS a life and enjoys other things, so he got a kick out of my struggles with this IOC. BTW, I have managed to disassemble a good portion of the 1.3 version of the firmware (not the newest, but something that I started disassembling many years ago) and figured out some of the beep codes. Beep 1 and Beep 2 happen after checksumming the EPROMs. The pause next is a RAM test. It has 2108's, eight of them, so that is...a whopping 8k bytes I think! It takes a 2.4MHz 8080 a little time to cycle through them. The third beep signifies that the RAM test was successful. Next is still kind of fuzzy. It looks like it starts using a real stack, since the ram is good, and then initializes the CRT controller chip. It looks like it needs to see some kind of status returned from it to continue. There are at least three places that it can halt before the next beep, and the 8275 CRT controller is one of them. So that may be my problem. Now I'm looking for an 8275 chip. Can't find one just yet, but I just started looking. I might have to disect a working MDS to swap some chips. BTW, the one white MDS I got from you that didn't work...well, the IOC was totally dead on it. Based on this work on the disassembly I determined that the first beep can also fail to happen if the 8253 counter/timer chip isn't working. That is one of the signals that gates the beeper "on". I replaced that chip on the IOC from that machine and now it gives me three beeps, just like the one that started this whole journey. Interesting, at least to a nerd like me. Well, more to come, I hope. What a way to spend a long holiday weekend! At least it doesn't cost me any gasoline to do this!!! Take care, and I'll keep the list posted if there is anyone interested.

Typical costs for a flyback for a small monochrome terminal range from $35 (used pull) to $60 (from a TV-parts distributor). If you find another VT220 with a good flyback but a weak CRT it's fairly easy to swap CRT's or flybacks around in the "take two bad VT220's make one good one" tradition. Tim.

My policy on repair/restoration has not changed since the last time we had this 'discussion' on the list.... A classic computer should, if at all possible, be got working. The use of a computer system is to run programs. If it doesn't work, it's just a metal box with some chips in it. However, you should replace as little as possible to get it working. This means replacing simple componnts, not whole boards. It also means not replacing things _unnecessarily_. The electronic design of the machine should be unchanged. In particular, replacing the guts of a classic computer with a PC running an emulator is not 'restoration' (this does not mean emulators don't have a use in preserving classic computers and their software, it just means that an emulator is _NOT_ the classic computer). Now, as a hardware person, I would claim the electronic design goes way beyond the design of the CPU, It includes the peripherals, and the PSUs. BUT, I don't have any problem at all with designing plug-in interfaces for classics to modern peripherals (doing that does not in any way damage the rest of the machine). In the case of PSUs, I'd rather they were kept original. If you haev to replace a linear PSU with an SMPSU to save electricity, then IMHO the original linera PSU should be kept with the machine (and preferably left in place, with the SMPSU hung off the back of the rack!). I would also do small modifications to improver perfomance or reliabilty. I have no problem with filling up a half-stuffed memory board, for example. I certainly have no problem with replacing cheap IC sockets with turned-pin. If I desolder a programmed chip to dump the contents, I often (but not always...) put it back in a socket, and if I do that, I always use a turned-pin one. There you are.

I'd rather use the right part, but if you can't get it.... In the case of a rare machine, you should keep a record of all the work you've done, of course. If the service manual is in a looseleaf binder, I put an extra page in the back with the modifications detailed. -tony From ard at p850ug1.demon.co.uk Sat Sep 3 17:44:25 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Sat, 3 Sep 2005 23:44:25 +0100 (BST) Subject: VT220 symptom In-Reply-To: from "9000 VAX" at Sep 3, 5 08:55:58 am Message-ID: > > Hi, list, > My VT220 went crazy yestoday.

I didn't think the VT220 PSU did this (it's not a mains-side switcher). The VT320 certainly will (can I just check you are talking about the 220). The fact that the LEDs come on suggests the problem is not on the 5V line, since that must be coming up to power said LEDs. Most likely, and it's a total guess without seeing the termianl, you've got problems in the line output stage (horizontal output stage to you, I guess). Either the transistor has shorted, or the (flyback) transformer has failed, possibly taking the transistor with it. Seen it happen far too often on the VT320... Start by pulling the case, finding the flyback transformer, and finding a power transistor with the collector connected to one of the transformer pins. That's 99% likely to be the line output transistor. Desolder it and check it. -tony From ard at p850ug1.demon.co.uk Sat Sep 3 17:55:32 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Sat, 3 Sep 2005 23:55:32 +0100 (BST) Subject: Intel MDS Series II IOC question In-Reply-To: <431A056E.1080208@mich.com> from "Dave Mabry" at Sep 3, 5 04:19:58 pm Message-ID: > >>Darn board-swapper guides... > >> > >> > >> > > But if they didn't tell you that then haven't to tell you how to fix the > >IOC board and provide schematics, etc. So telling you to replace the board > >is an easy out for the manufacturer.

If so, can you get it to grab the address when it halts? That would at least tell you which halt it was getting to, and then you could trane back to see what could have caused it. Another trick I used once.... Make a 16 bit comparator (a couple of '688s or something). One set of inputs to the CPU address bus, the other to DIP swithces and pull-up resistors. The output of the compatator to a logic probe (or monostable [1] + LED). Presumably there's a conditional branch that sends the CPU to the halt, or a conditional branch that keeps it looping waiting for the right status, or something like that. Set the DIP swtiches to the address just past that branch -- i.e. where the CPU would get to if the test is sucessful. See if the CPU ever gets there. [1] I know I've complained about the _misuse_ of monostables in the past. IMHO driving an LED is not misuse. > Take care, and I'll keep the list posted if there is anyone interested.

So I have to try to revert the machine back to it's original state. The serial plate didn't survive the fossilization over the years(it's gone), so I can't determine what serial number for this. I still couldn't determine if this was a 680 or 680b from the looking at the manual.

The IOC board is the back panel board on an Intel MDS Series II that handles most of the I/O of the system. It does a lot! It is based on a 2.4MHz 8080A cpu. Well, I broke out an Intel ICE-80 and hooked it up. This is the first In-circuit emulator that I know of, perhaps the first ever. It is quite primitive, but it can do a lot in the hands of a skilled operator. If I ever find such an operator, maybe I will be able to fix this damned IOC board!!! One of the problems I encountered with the emulator is because the RAM in the target system is dynamic. I think that when the emulation "breaks" from a breakpoint it seems that the RAM loses its contents. Perhaps the refresh circuitry relys on a clocking cpu. But it does look like I get inconsistent results reading the ROM on the IOC board. So I will now look at the buffer chips and maybe the address decoding. I tried to map the execution memory to the host MDS (that is the machine that is hosting the ICE-80), but since that slows execution and there are some software timing loops that didn't work very well. I am making progress, slowly. And putting two of these beasts together (one working one for the ICE-80 host, and the "target" system that needs to be fixed) isn't trivial. They weigh about 100 pounds each!!! It was a comical scene, though, with two MDS Series II systems side by side. I thought my table was going to colapse and the lights dimmed when I turned them on. ;) Stay tuned...I have some more disassembling to do.

So if, for example, Sellam had one of these interfaces, would it be near to 'plug-and-go' for his 3803-controller/3420-drives combination, or would their be a lot of 3803-specific software-driver development on the modern-host side (and requiring the acquisition of 100 lbs. of 3803 manuals) ?

With it you can create a memory map of the IOC, test the RAM, dump the EPROM contents, set breakpoints, run it on the IOC's CPU or the 9010's CPU, test all of the data and address lines and more. The best part is that all you have to do to connect it is to plug it's cable into the IOC's CPU socket and place the CPU in the test pod.

Pretty much plug and go. It's very much like a SCSI interface. Each device has a set of commands documented in its Functional Characteristics manual: read, write, get status, etc. You'd find this in the device's documentation (e.g. 3420) rather than the controller's (3803). The commands do follow a common pattern although there are some variations between devices. The Bus and Tag protocol communicates these commands from the channel (the interface in the CPU) to the device controller, and returns the results. There are several different transfer modes (byte at a time, burst, etc), different ways that the device can signal the CPU for attention, and various ways that either the channel, the controller or the device can say "hang on, I can't do that right now," so it's fairly complex. The logic frames for a typical channel interface built with 1960s vintage SLT are about the same size as the IBM 1130's CPU, for example. I suspect that data buffers (RAM) are a significant part of that. But from the programmer's standpoint, it's very simple. An IO command points to a "channel program" which is usually just a device command word and a data transfer address. The channel takes it from there, and an interrupt is issued when the operation is complete (usually). Channel to controller cabling is standardized, two thick cables. Controller to device cabling is device specific. Some devices have an integral controller. brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel _| _| _| Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 _| _| _| Fax: 1-510-525-6889 _| _| _| Email: brian at quarterbyte.com _| _| _| http://www.quarterbyte.com From kth at srv.net Sun Sep 4 13:12:47 2005 From: kth at srv.net (Kevin Handy) Date: Sun, 04 Sep 2005 12:12:47 -0600 Subject: VT220 symptom In-Reply-To: <431A0A6E.nailIOE1Y335G@mini-me.trailing-edge.com> References: <4319EB91.4020704@srv.net> <431A0A6E.nailIOE1Y335G@mini-me.trailing-edge.com> Message-ID: <431B391F.3060501@srv.net> Tim Shoppa wrote: >Typical costs for a flyback for a small monochrome terminal range >from $35 (used pull) to $60 (from a TV-parts distributor). > >If you find another VT220 with a good flyback but a weak CRT it's >fairly easy to swap CRT's or flybacks around in the "take two bad >VT220's make one good one" tradition. > > > Instead of swapping the flyback, just swap the whole circuit board.

However, I am always interested in more RT-11 software, especially distributions. Even if they are duplicates, they can be used to verify existing copies! I have been a bit busy of late attempting to clear the mess in the house PLUS looking a calculations for PRIME numbers. While really big numbers are not required, 32 bit integers are not at all sufficient and even 56 bit floating point are not able to handle the calculations. What are really needed are 256 bit floating point numbers, although 128 bits for the integers and 64 bits for the fraction would probably be sufficient. At this point, I am in the midst of writing the subroutines myself. I posted an inquiry recently about that problem and the responses were appreciated, but did not provide what is needed. For the integer subroutines: DFLOTL - converts INTEGER * 16 to REAL * 8 LIDINT - convert REAL * 8 to INTEGER * 16 LICLR - clears an INTEGER * 16 LIINC - increments an INTEGER * 16 LIADLI - adds INTEGER * 16 to INTEGER * 16 LIMVLI - moves and INTEGER * 16 to INTEGER * 16 ENLI - encodes an INTEGER * 16 into CHARACTER * 40 I will probably also be using LD type of routines where the L is for the 128 bit INTEGER * 16 portion and the D is at least 64 bits (or REAL * 8) of fraction for a combined total of 192 bits. But more likely at least 128 bits of fraction will be needed - maybe use the letter C? If I find I require: LIMULI - multiplies INTEGER * 16 by INTEGER * 16 LIDILI - divides INTEGER * 16 by INTEGER * 16 If anyone has any suggestions, they would be appreciated! >Jay West wrote: > An unknown PDP-11 system is available in Canada, PQ, Montreal. > > The description I received was: > ------ > I have a PDP11 system to sell with 3 unit of disk RL02 + a dozen of > disks.of 10 megs. > and 2 or 3 VT-100 terminals, plus 2 printers LA120 > --------- > > My impression was it won't be free, but possibly reasonable.

IIRC on the IBM PC, the DIN and DOUT pins are linked on the >RAMs storing data bits, but wired separately on the RAMs storting the >parity bits. What is the point in using them separately? Was it for the case where the destination of a read is different from the source of a write? I could see where that could happen in parity checking. For the data bus though, the source and destination would be the same. For a little while I thought it might be for some odd timing advantage. But since the write data isn't required on the bus until just before the CAS anyway, I don't think the timing idea could be valid. Besides separate IN and Out could only confer a speed advantage in the cases where a Read followed a Write or vice versa. >If you have the machines that are supposed to use these 64 pin SIMMs, can >you not just check to see if DIN and DOUT are linked on the mainboard >with an ohmmeter? I don't have a IIfx or the SIMMs yet. I was exploring the feasibility of the project first. However, I posted a WTB to the austin.forsale news group and got lucky with a fellow who wants to give a IIfx away. So next week I should have hardware to explore. It's nice to avoid shipping when shipping would be greater than the value of a machine. Still, I would like to get my hands on the Apple Hardware Developer Note for the IIfx. It should at least mention whether they were using separate data_in and data_out for some timing related purpose. Of course, if an ohmmeter reveals that In and Out are tied together on the motherboard, then I'll have my answer.

(No flames, please.) As so many on this list I abhor seeing things scraped if they are useful. As with much of the older mainframe stuff, however, it is very big, and an isolated unit is not generally useful by itself. So here is my problem. Our museum is a part of a big state university. I go by the surplus department once in a while and see some interesting stuff that I take back to our space and add to our inventory. If it has a residual value on the books then it is transferred to our department. If it is not on the books then I just take it and there is no record of it. In the latter cases I have been known to swap newer stuff for other older stuff we are interested in. Yesterday I went by and there was a nice IBM 3725 front end processor. It is not anything attractive for a museum visitor to look at. It takes up a lot of valuable display space (roughly 2 racks & about 5' tall) for something kind of obscure (for most people) and not at all visually interesting. Now I have no idea what our surplus department generally does with such things. Assuming that there is no actual market for it, I could probably go over there and get it for our museum. Right now I could probably even store it, at least until something more attractive came along. On the other hand, when we get to the point that we are a bona-fide museum, with lots of visitors, I can see raising some much needed cash by parting this thing out. I am sure there are lots of boards and control panels that could be sold individually. I would envision tagging these parts as being a souvenir of the museum, much as I will with punched cards, 8" floppy disks, 5-1/4" disks, etc. I guess a third alternative would be to sell or trade it to somebody on the list for something that is more visually interesting and perhaps smaller.

Does anyone know a good solution for putting a large drive in an XT, > while still leaving it an XT? There are a couple issues, the first being interface, the second being BIOS, and the third being DOS. 1. I'm not familiar with the IDE interface you mentioned. If it's an 8-bit IDE interface you're likely to have problems with 16 bit drives. The drive geometry information will be garbled at best... SCSI should work OK provided the drives support whatever the controller provides (which I would assume would be SCSI-1 (single ended, 5 MHz)) You should check whether TRM_PWR is supplied by your controller and try an active terminator, rather than any autotermination. I've found that some drives don't autoterminate SCSI-1 properly. 2. Your XT IDE controller is likely to be limited to 504MiB drives without a BIOS upgrade. Your XT IDE controller is unlikely to be doing any translation of block addresses required for LBA. It's probably doing cylinder-head-sector addressing. If the BIOS was written for DOS 4.X or earlier it's probably calculating size as follows.... cylinders=true_cylinders mod 1024 heads=true_heads mod 16 sectors=true_sectors mod 64 Although a SCSI controller shouldn't have these constraints, you never know till you look. 3. Depending upon what DOS you use, you may have a limit of 128MiB (Dos 4.X), 32MiB (Dos 3.X) or 16MiB (Dos 2.X and earlier). Your best bet for debugging is to upgrade to Dos 5.X+ and get smaller drives and use the largest one that works. 2. Should I leave the V20 in? I've heard it has compatibility issues > with some programs, but I'm not solid on my information. I've never had a compatibility issue using a V30 in an 8086 machines, except with very early copy protected games... Fortunately I could select speed and wait states from the keyboard and found that 4.77 MHz with 3 wait states generally came close enough to an XT to fool the game.

BTW, I think the LBA PRO is a replacement AT BIOS, and won't work on an XT (which doesn't have a interface independent BIOS like the AT does.) Having it on an 8-bit card confuses the issue, but since it's in the lower meg of address space it doesn't need the extra address lines, and 16-bit memory access would have meant a 16 bit wide ROM and more expense for card manufacture..

I will ask where that came from. At least I could ask them for first refusal on their disposals. I did rescue a 3275 a few weeks back.

At least the 9121 guy has some new pictures. Same price, however. Anyway, not all 3725s are channel attached.

(Otherwise you don't even know if they're even or odd!) So if you're using floating point numbers, you are limited to the size of your mantissa; which might be a convenient way to get something bigger than 32 bits, but it won't get you any bigger than your mantissa. (Well, you get one bit for free if your floating point representation uses the implied leading zero.) So I'm with the others: Knuth + arbitrary precision. There are some other good books on specifically arithmetic with primes. May I ask what it's for? Best regards, J.

This is not really difficult to do, but it is VERY time consuming. Turns out that I have been working on two different versions of the firmware...VERY DIFFERENT. The earliest version of IOC firmware that I know of is called V1.3, or at least that's the signon version number for the diagnostic code within it. Intel released a major enhancement for that firmware in about 1982 or 1983. They sold a package called the iMDX-511 that included the newer firmware and new code for the 8741 cpu in the keyboard. All MDS Series II's sold after that date had this code right out of the factory. The enhancements included cursor addressibility, some character attributes (like underline, bold, reverse video), soft keys that included some of the common ISIS-II commands, and other things like that. Interesting how this was a major enhancement at the time and is, of course, taken for granted by computer users today. So, I'm still working on disassembling, understanding, and commenting the V1.5 code for the IOC. If anyone is interested (Tony, you said you were! :)) I have put it online for anyone to snatch. It is the ".LST" file output from Intel's ASM80 Macro Assembler. That is the file that you would send to a printer, so it has lots of info. If anyone is interested enough to help me a bit, I would like to understand where the RAM diagnostic is in 1.5. I have identified it in 1.3, but V1.5 looks to be completely rewritten. The two versions are here: http://www.mich.com/~dmabry/intel/ioc When I have enough information on V1.5 I'll break out the ICE-80 again and dim the lights in my neighborhood! :) Dave Mabry From cannings at earthlink.net Mon Sep 5 15:35:13 2005 From: cannings at earthlink.net (Steven Canning) Date: Mon, 5 Sep 2005 13:35:13 -0700 Subject: Mass Memory Unit from Space Shuttle References: <3.0.6.16.20050903155922.32d7abbe@pop-server.cfl.rr.com> <431A5E60.ED0E7F00@guntersville.net> Message-ID: <003801c5b259$519bddd0$6401a8c0@hal9000> John is correct about the 5 Volt logic control signals. The prime power is +28 VDC spacecraft power. They have in-rush current limiters on the prime power input and will run down to + 24 VDC and up to +32 VDC ( there is a pre-regulator up front ). These are linear scan units ( not helical scan like a VCR ). Sounds like you have the MMU ( Mass Memory Unit, the smaller one ) and not the STR ( Standard Tape Recorder, the big guy ). These units ( MMU ) were digital only, and were used to download programs to the five general purpose IBM computers ( configured like IBM 360s ). Part of this function was to drive the " glass " dashboard ( CRTs) that provided info on engines, etc. There was not enough room for all the standard instruments on the " dash " that would have been required. So you could pull-up " virtual instruments " like they have on the Toyota Prius dashboard. The two tape reels were not driven, but maintained tape tension through differential gears connected to a " gyrator " spring that provided relatively constant torque between the two counter rotating reels. The tape was " pulled " through a proprietary delta drive capstan system which incorporated the read / write heads. Remember this thing has to survive the G-force of liftoff and run in a micro-gravity environment. Best regards, Steven Canning ----- Original Message ----- From: "John C.

FYI, I did manage, earlier this spring, to try and bring up my Z-2, but so far not so good. I got the power on (and measured it for general reasonableness). Once I hooked it up, it immediately blew a power filter capacitor on one of the floppy drives (this was not really a shock -- I had re-formed the main electrolytics, but didn't do that on each board or drive), which I replaced. So, I thought I might test the Z-2's floppy controller and CPU in my Altair chassis. I did get that running, but then I got distracted -- it was an obvious chance to snag the images of all of its disks (Micropolis-I, Micropolis-II and 8"), which I did, though the old beast was a little cranky from time to time. (Long ago I had written an imaging program I called "XMT" which used a little protocol I developed to transfer files and disk images reasonably reliably. All I had to do was write up the PC side. Uses a serial port). The system is not saying anything, but I was also short on docs, so after a few hours I kind of gave up on it for a while late in April / early in May. HOWEVER: I just stumbled on a big box full of stuff that came with my Cromemco. (Happy, happy, joy, joy). I had had the inkling that I had some stuff for the Z-2, but this spring I was looking just for a little floppy box. Today I am doing some cleaning, as things had gotten pretty out of hand in the finished part of my basement. After I got that cleaned up to the point where there were some electonic hardware things (PIC programmer, parts for a PIC project, etc.) that I wanted to put onto a shelf, I turned my attention to a shelf I had stuck some stuff on while we had some work done on our house *last* summer (over a year ago). On top of that shelf was a "copier paper box" chock full of manuals, doc -- and floppies -- all for the Z2!. So, now I guess I'll have to get motivated later this fall (probably late October before I can get to it) and find out what is making the Z2 unhappy and get it working again. Docs will make it a lot eaiser. ;^) And, of course, I may well still need the CDOS image -- I don't know if the two boxes of 5" floppies I have for it are any good (though my recovery of old Altair floppies was well over 95%, and most of the ones that were bad I knew were bad years ago -- my basement is cool and dry so things tend to keep remembering). The moral of the story: House cleaning is a good idea once in a while. 8^) At 10:09 AM 4/30/2005 -0500, Jay Jaeger wrote: >Thanks a bunch.

It's no use if you want to link the data pins to a bidirectional bus. I've seen DRAM boards with separate input and output buffers, converting the bidirectioanl off-board bus into seprate input and output buses to the DRAM chips themselves. It's also useful when you're using the DRAMa in a video display circuit and want to feed the DOUT lines to the shift register. I suspect the _real_ reason for it was that there was a spare pin on the package and it didn't ever make life more difficult to have separate DIN and DOUT pins (oyu could just strap them together externally if you wanted a bidirectional data pin). -tony From swtpc6800 at comcast.net Mon Sep 5 16:37:59 2005 From: swtpc6800 at comcast.net (Michael Holley) Date: Mon, 5 Sep 2005 14:37:59 -0700 Subject: Fragile book scanner [was Re: DEC Computer Lab] References: <200509051700.j85H04Ct048634@dewey.classiccmp.org> Message-ID: <000901c5b262$1ed03d70$0300a8c0@downstairs2> I just found this scanner online, I have no experience with it.

The Integral manuals I have mention it exists, say it installs like any other board, and that you need a normal 'modular phone cable' to link it to the phone line. Nothing I'd not worked out by myself. Incidentally, I have no intention of linking it to a public phone line, I just want to connect it to another modem. I suspect it'll work withont any DC voltage on the line, if not, that's easy to fix. Did anyone, though, have a cheap/homebrew device to link 2 modems back-to-back, doing things properly with dial and ring tones, etc? -tony From ard at p850ug1.demon.co.uk Mon Sep 5 16:26:29 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Mon, 5 Sep 2005 22:26:29 +0100 (BST) Subject: Rockwell R1212DS modem chipset Message-ID: The HP 82915 Modem (for the Integral) that I mentioned in another message, uses a 3-chip chipset from Rockwell. The chips are R5313-14, R5132-14 and 10464-14. THe first 2 are 64 pin QIL zig-zag pin packages, the last is a 40 pin DIL. Now, I have the 1985 Rockwell databook here, which covers modems. It appears you could buy a ready-assembled PCB from Rockwell containing these chips and the support components. I have data on that. You could also buy the chips not-on-a-PCB, as the R1212DS 'device set'. Alas I have no real data on those, the book refers me to 'R1212 Modem Device Set Manual', order number 652. And I don't have that. Does anyone have it? Failing that, does anyone have 'R2424 Modem Device Set Manual), order number 651 (this is the 2400 bps version). The chips seem to be somewhat related. What I am relally looking for is complete pinouts of all 3 chips. This may not be in those manuals, though. I have the service manaul for the Amstrad PPC, which includes a schematic of its internal modem. That used the R2424 chipsset, but the schematic does not name most of the pins on these chips, only those that go to other parts of the modem. The internconnections between the 3 chips in the chipset are shown, but not named. I am wondering if the Manual just told you to link pin 7 on the Tx chi to pin 15 on the Rx chip (or whatever, that is a ficticious connection!), and didn't tell you what that signal was. -tony From jhfinexgs2 at compsys.to Mon Sep 5 21:04:11 2005 From: jhfinexgs2 at compsys.to (Jerome H.

Second, the basic problem is that the FORTRAN 77 routines for the PDP-11 under RT-11 are not even accurate beyond about 12 places of precision using FORTRAN 77 floating point conversions. So even if the value is correct internally to the 56 bit mantissa of the 64 bit floating point value, it is not possible to depend on the displayed result. Third, arbitrary precision routines have too much precision relative to what I actually require most of the time - which is only about 80 to 120 bits for integers. The area I am interested in is probably best described by the information at: which has a 22 digit number as the biggest value in all the tables there. So 128 bit integers which require only 16 bytes are more than sufficient. The required subroutines are easy to code in MACRO-11 and will be suitable for what I need without the added overhead of subroutines that can handle numbers with thousands of digits, let along millions. The biggest problem that I have encountered thus far was how to encode such a large integer for output. The standard method for small numbers is to just subtract powers of ten. But I needed a table of 16 bit values to place in each if the approximately 38 entries in the table, each entry being 8 * 16 bit words. So I just used the subroutine that performs addition on 128 bit values to produce the powers of ten and then use the FORTRAN 77 octal output to write the 8 word entries to a file. That file was then used in the MACRO-11 program. Actually quite a reasonable way to let the computer do the accounting details while I did the program to use the table. I realize that I omitted the actual size of the words I want to work with ( i.e. 128 bit integers) which are actually quite small compared to the really huge stuff which deals with and handles values with over a million decimal digits. For that, I apologize.

The first couple of magtape drives for PDP11s from DEC all had vacuum columns. It wasn't until the TS03 and TS11 ("tape stretch 11") that DEC tried to do it on the cheap without vacuum columns. paul From pechter at gmail.com Tue Sep 6 08:52:52 2005 From: pechter at gmail.com (Bill Pechter) Date: Tue, 06 Sep 2005 09:52:52 -0400 Subject: WPS All in One files...

ONE sales brochure list it in ONE place but give NO details or pictures and never mentions it again. The service manuals don't give ANY details about it. (It's one of those "If it fails, replace the CCA. If it still fails, replace the whole thing." procedures.) To test it they have you install two modems in the IPC and plug them into separate phone lines and call one from the other while running the diagnostics program. The diagnostics program will report No Carrier, No Dialtone and the like but that's all. There no mention of a null-modem type cable.

An extreme example is the boot loader for the 360/44 emulator facility -- that's a chunk of magic hidden memory and logic that allows the 44 to execute SS (character/decimal type) instructions. It doesn't natively do that, so it traps to the emulator, which does the work. So you can run OS/360 and COBOL or PL/I applications (very slowly). The emulator is loaded from a card deck, via the "Emulator IPL" button on the console. The deck is a plain assembler binary deck, exactly as you could get punched out for any binary, with address and data length fields on every card. The channel program is self-modifying; it uses data and command chaining to read the address and length fields of each card into another channel word, which then transfers the right number of bytes to the right place -- repeating until the deck is finished.

I don't have an A1 card for example, and the core memory is completely different. I'm kinda beating my head against the wall on this one. Still hoping Bob or someone else will dig up a Volume 2 manual for the 2116A sometime soon. =/ In the mean time, I've repaired and powered up the HP-2108A system. Things seem to checkout ok. Now anyone want to suggest a light chaser program to key in for kicks? I don't have any manuals specific to the HP-2108A here, but I suppose I should try some of the memory diagnostics routines from the 2100 or 2116 to check things out. The basics seem to work. I can store/recall values from registers and memory. I've not tried all memory locations or anything yet. I'm hanging out on #classicmp on irc.freenode.net as usual. I was hoping Jay would be around sometime or others that might suggest what to do next. ;-) My paper tape reader seems to spin up ok now, but I've not tried to talk to it in software yet. Also I don't have real tape images for things like the basic1 environment: http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs I've got my hacked simh that has ANSI text register displays to test out routines on. That's been very useful. ;-) Any suggestions on getting pc based paper tape images over to real HP hardware? I do have a paper tape punch, but no docs on it.

Yes, but I'm not sure of what platform and cost. I'd never considered it. You'd also need a VMS license and they are not cheap. I have an advantage as I was engineering for DEC and took a deal available to employees back then. However that limits me to V5.x versions but thats ok even though 7.3 is current. You can check www.montagar.com to see what the hobbiest license entails. There is an active newgroup comp.os.vms. > 2) Does OpenVMS support the notion of shared libraries (DLL to you windoze > users)... Yes but very different from winders. Never did a direct comparison to winders or unix. Also all the winders work I do are either at the hardware level (boxes and networks) or Databases using delphi, paradox and SQL in a server envirnment so I rarely look at the lower levels of winders unless forced to. Though I've done stuff at the other extreme on PCs in the DOS and QBasic4.5 as programmed controllers. > I want to re-port an old application, but want to use OpenVMS instead. I > don't have a machine that is capable of running VMS (nor do I have the space > for one), so an emulator will suffice.... If you can find a uVAX3100 (microvax3100, Vaxserver3100) that would do and they are small 18x4x16 and 180W power. Disks for those are 3.5" SCSI-1 or II typically. VMS on a 3100 only needs 100mb for itself so a 1gb drive is plenty of room. VAX systems of the microVAX flavor are fairly small though some of the bigger members can be a bit large. The smallest would be the uVAX2000 at about a 1/2 cuFT most of the 3100 series are desktop sized and the 6000 series are generally rack sized bigger systems. Stay away from the Qbus vaxen (MicrovaxII, 3500) as that will definately get you into the hardware realm though they are good machines. Also Qbus machines are more likely to have older disk interfaces (MFM drives) or other DEC unique disk. The Qbus machines are also likely to be missing key items like network card or enough memory. As to memory, anything with at least 16mb of ram will be OK although more is better. You need at least 12mb to run VMS decently starting with V5.x and 16mb with V7.x. My collection of VAXen include a pair of microVAXIIs and 3 MicroVAX200 and 8 3100s (mix of /m10s and /M76s).

The one that immediately springs to mind is CHARON-VAX: http://www.softresint.com/charon-vax/index.htm I'm not sure if they do a hobbyist version though. > 2) Does OpenVMS support the notion of shared libraries (DLL to you windoze > users)... VMS has had shared libraries for ever I think. They're EXEs that contain your subroutines etc and they're linked in a different way to apps. After that though you just add them into your link statement. You can also INSTALL them which makes them memory resident and multi-user so every app that needs access to them gets the memory copy rather than having to drag its own copy off disk every time. Surely you can get your hands on a small VAX like a 4000-60 or 3100 series machine, then you can get the hobbyist VMS licenses and you're off. -- adrian/witchy Binary Dinosaurs creator/curator www.binarydinosaurs.co.uk - the UKs biggest home computer collection?

The main cabinet is a "DEC DataSystem" rack about 5.5' tall. The RL02 and the Winchester are housed in a DEC cabinet about 3 to 4 ft tall. Finally there is the "desk" which holds the floppies.

This sounds more like what I want to do. I am in the process of re-writing the iserver transputer host communication application to be a bit more open. Currently, all the drivers are linked into the application which makes adding new driver support a pain. I want to dynamically load the library from the application itself. For example, the configuration file would be like this: |c0t5l0|T|localhost|/dev/c0t5l0|transputer.so|||| So, when the application configures itself for c0t510, it will dynamically load the file transputer.so and use the device /dev/c0t510 as its resource (this is NOT a real example). Is this possible? The library will have the standard INMOS communication API present (OpenLink, CloseLink, etc) Thanks, Ram From rigdonj at cfl.rr.com Tue Sep 6 14:50:17 2005 From: rigdonj at cfl.rr.com (Joe R.)

It looks like any other Integral PCB. As I said, about 17 chips, a crystel, a crystal oscillator, a 3 terminal regualtro, a transformer, a reed relay, a transistor, and some passives. 2 US-style phone sockets on the bracket, both unmarked (may just be wired pin-pin, with the appropirate pair of pins also going to the modem circuitry). > service manuals don't give ANY details about it.

Repairing it would probably violate the FCC approval (it would certainly violate BT appoval for a UK modem). Since I don't intend to connect this to a public phone line, that doesn't bother me. That said, the HP Portable Plus service manual (I have it) does give some repair procedures and a scheamtic for its internal modem (totally different ot the IPC one, BTW). I does say that certain components (mostly resistors) must not be replaced in the field, since this could affect the FCC approval (incorrect transmitter level, etc). > procedures.)

It's quite possible to run one with a serial console, so if you have any machine with a serial port, a terminal emulator program and a null-modem cable, you're in business. Peace...

I had several of the smaller boxs and one larger box that I hadn't looked at yet. I just finished examining it and I found that it's one of the larger analog and digital boxs that Steve described. It's labeled "Recorder, Magnetic Tape-Wideband Digital/Analog (Shuttle)". Not only did I get it but I also had some kind of test panel made by Odetics that I also picked up. It turns out to be the test panel for this unit :-) But wait! I also picked up a big bundle of cables that were laying nearby and it turns out that it had ALL of the (intact!) cables for it! After I took the pictures I found a bag of connectors that are labeled as "Shuttle Tape Recorder Connector Savers". Apparently these are connectors that mate with the connectors on the tape recorder to prevent any damage to them when the regular cables are removed. At least one of the smaller units already had those installed when I found it. Pictures at I must be living right!

Most of the 3100s (and uVAX in general) can be booted and run headless. So when I need to connect to mine I use a VT1200 Xterm over the network and I suppose a PC could be configured for that. That reduces the working system to a pizza box somewhere in the room on the network. Allison From chd_1 at nktelco.net Tue Sep 6 18:09:24 2005 From: chd_1 at nktelco.net (Charles H.

They made a series of machines (I vaguely remember a model 4.) They were somewhat like a 360/30, I seem to recall. Their chief claim to fame was that they were designed to be microprogrammable. I think one of the implementations used a set of wires strung through a series of W-shaped transformers. Passing the wire through 1 side resulted in a 0, and the other side gave a 1. Thus it was possible to change the microprogram and thus extend the instruction set of the computer.

Originally written in basic, it was later partly recoded into something else that compiled into executable code (probably macro and basic+2) to speed it up. DEC later bought it and renamed it to DecWord, iirc. It could communicate with a WPS-8 system and transfer files, but they didn't used the same file format. It was similiar, but Word-11 was based on 8-bit chars, while WPS was based on 12-bit chars. I once started a program to convert Word-11 files to WordPerfect, but don't know what happened to that version. I don't have any Word-11 files anymore anyway.

I suppose that, for its time, it was not too bad. I was glad to upgrade to TeX though! I don't remember anything by the name of DECword, but there was a DECwrite. DECwrite bore no resemblance to the Word-11 that I knew. As for the original question, somewhere I have a set of 3.5" floppies that claim to implement WPS-PC (or some not entirely dissimilar name). I can probably dig them out at some stage if anyone cares enough about them (and I can find them :-) and they are still readable :-( ). >From what little I do recall about those floppies, it looked like a DEC product.

And you don't need anything specific to the 2108. Look in the CE handbook. Common data I think is the section (going from memory). There are quite a few short ditty's there that you can enter via the front panel and use to test the system for basic function before heading to diagnostics that require certain things to work. Most of the ditty's there are expressly designed to test the functions that are required to load diagnostics, so there is little or no guessing. Make sure you run the diagnostics (from media) in the order put forth. Once you get past the ditty's in the CE book, let me know what media you have to load diags on.

Well, that's the issue. I don't have any media working yet. My paper tape reader might work. I've not tried reading from it yet. >> Any suggestions on getting pc based paper tape images over to real HP >> hardware? > > Since you expressly limited it to pc based paper tape images... there is > a solution.

Also, what does an ASR-33 do to load tapes? or perhaps it's tape drive cannot be used for diags/booting? (I don't have an ASR-33, I just figured it might be easy to emulate) >> I do have a paper tape punch, but no docs on it.

I collect S/36 equipment, and I have most of the manuals, some of them scanned. Consider me a resource. A couple of answers to your questions: Q: Is this like the AS/400, where if it doesn't come with an OS and firmware disk it's toast? A: No, thankfully. So long as you get the media, you're alright. There's even a way to hack around security if it's absolutely necessary. Q: What sort of drives does it take? A: As far as I know (and I haven't really explored the topic) it takes model specific drives. The file system seems proprietary to the hardware. Sellam may know different. I defer to the great one on this. Q: Is it 220v only? A: That depends on the country of origin and the model. There were four main series: 5360 - 220v only as it was a datacenter class system, 5362 - this was the deskside type with a country default power requirement 220v/110v, 5363 - another deskside but later and switchable if memory serves, and the 5364 - this one may also have been switchable, it's a desktop unit... mine's in storage or I'd check for you. Q: Any other weirdness? A: Gee... um where to begin. The system's totally unlike VMS/Unix/PDP OSs. I suppose the weirdness depends on your perspective. The basis of comparison is the AS400 since that's what superceded it. AS400 added a relational database system and more systems' management. But the underlying operating systems are rather similar. On the other hand, the hardware's totally different. S/36 (and this is distinct from AS/36) is a 16bit operating system with dual CPUs, one dedicated IO/Memory management. It's a flat address space. The system was targeted as a total office solution, and indeed it offered a very modern set of capabilities. The original strategy of office networking was based on PCs talking to a S/36. Files could be shared, there was e-mail, word processing, and a database/development analogous of non-relational MS-Access. You could pretty rapidly create tables and then build forms around them. It had it's own development language RPG, which was analagous to a VBA as it was really built to further enable the database application development. It originated as a reporting language on earlier IBM systems. Other languages were supported, Basic and Cobol come to mind. Sorry, no C. The whole thing's rather interesting when you're used to the file system based world and open systems. IMHOP its well worth playing around with if you have the wherewithal to do so. If you're into hacking it may be disappointing as it's a very closed and proprietary solution base. But if you get off on clever technology design, the rapid deploy piece of office automation is fascinating, and it does have a number of mainframe centric networking solutions available to it in addition to the twinax native to this range.

FWIW CCC used to be National Postal Meter and they made M1 carbines during WW II. In early 1945 they saw that the end of the war was near and they wanted a more commercail name so they changed their name to CCC.

According to rumor it was based on a very very ancient version of FrameMaker. It did become reasonably capable (certainly better than MS Word of that era) before it was canceled. We used it extensively in the DEC network architecture group (replacing Runoff), which may be one reason why DECnet Phase V specs are not available anywhere. DECword does ring a bell, but it sounds like a late name for what was WPS-8. The PDP-11 and VMS analog was WPS-Plus, and that was written from scratch, in a very short amount of time, at DEC. I never used it on VMS, but did suffer with it on a PDP-11 (Pro under P/OS, in fact). It worked, and it was reasonably functionally compatible with WPS-8, but the performance was pathetic. paul From glen.slick at gmail.com Wed Sep 7 08:54:54 2005 From: glen.slick at gmail.com (Glen Slick) Date: Wed, 7 Sep 2005 06:54:54 -0700 Subject: HP 21xx update In-Reply-To: <431E7698.9080607@Rikers.org> References: <431DD548.2070309@Rikers.org> <016901c5b362$35e3b6d0$6500a8c0@HPLAPTOP> <431E7698.9080607@Rikers.org> Message-ID: <1e1fc3e90509070654bfc3ee6@mail.gmail.com> > > Since you expressly limited it to pc based paper tape images... there is > > a solution.

Do folks have a recommendation for suppliers of circuit board making materials, or a good source of such information? I've found a number of web sites and read them. The difficulty is in knowing which place has better/cheaper/easier supplies than other places--knowledge which generally comes with experience. And several of my other questions are the kinds that generally aren't answered on websites but that one learns from experience. One complication is that I want to make a few different designs which need to be on .050" thick board. Standard board these days is .062", which rules out the affordable proto-type services that I have used in the past. In fact, I have not been able to find precoated board (photoresist coated) in the .050" thickness. So I will either need to use a liquid photoresist or try a toner transfer system. That raises other questions. Are the Toner Transfer Systems reliable (doesn't leave broken/smeared traces)? What resolution (line and spacing thickness) can one generally get with them? The TTS would be simpler. I wouldn't need liquid PR, developer and stripper, plus a UV source. If the TTS is not servicable, then I'll try the liquid photoresist. Would it be better to simply spray on, or should I try to rig a spinner? Do the developer and/or stripper usually turn out to be some commonly (cheaply) available chemical? I would prefer to avoid paying $6+ for a small bottle if I can avoid it. Thank you for any info or pointers to info.

I'll be getting a IIfx on Thursday and I can confirm (I hope) that the DIN and DOUT are common on the mother board at that time. Your advice has given me hope that this is much more doable than I feared. If they're tied, then I should be able to build a 16MB SIMM using two 16M X 4 chips. My concern was that the X4 chips do not have separate DIN and DOUT and I wasn't certain if the IIfx actually needed the separation. I think I have some 16M X 1 chips which would work in either case, but my supply of 16M X 1 chips is much smaller. If the DIN and DOUT are common on the MB, and I use 16M X 4 chips, I assume that I should either use the DIN pin or the DOUT pin on the SIMM but not both? Using both could result in different length datapaths which remerge, possibly causing interference from slightly out of phase signals. The difference in length probably wouldn't affect the timing much, but still... It would still be handy if someone has a mechanical drawing of the 64 pin SIMMs. I can derive it from a physical example, but I'm less likely to get the actual center measurement and tolerances correct that way. Hmmm. I'll check around and see if any of the socket manufacturers are still selling a 64 pin SIMM socket. If so, I should be able to derive the SIMM dimensions from the socket datasheet.

I don't want to discourage Jules from trying, but any plane trip out of MN is going to cost at least as much as driving (jet fuel prices are going through the roof). The trade-off is (if by plane) you get there faster or, (if by car) you get to see a lot of America. I wish the airline industry in the States would finally just collapse and then rebuild itself into something more viable. I'm trying to get a flight to Vienna and prices are all over the place...above $2,000! Ridiculous. I had an opportunity to get a flight for under $750 yesterday and got distratcted. When I came back to do it again today it's now under $800 but with a 14 hour stopover in Madrid. It would be fine if it was during the day but it would be at night, I'd have to get a hotel, the Euro kills the dollar (Hans, I am drinking heartily from the Euro mug), and I just don't have time (as much as I'd love to walk around Madrid for the 8 hours or so I would be afforded after sleep).

Considering that a light-nanosecond (in free space) is about 1 foot, and that the velocity factor of a PCB is going to be around 0.6, I would guess about 8" of length difference would give 1ns of timing skew. I don't know how fast that amachine runs, but I would think you'd have to have a right stupid layout for using both pins to matter much. -tony From ard at p850ug1.demon.co.uk Wed Sep 7 12:41:07 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Wed, 7 Sep 2005 18:41:07 +0100 (BST) Subject: JF's calculations for PRIME numbers In-Reply-To: <20050906200733.3e7d5a82.chenmel@earthlink.net> from "Scott Stevens" at Sep 6, 5 08:07:33 pm Message-ID: > > On Mon, 05 Sep 2005 22:04:11 -0400 > "Jerome H.

A prime number generator is always one of the first programs > I code up on a new machine. A 'benchmark' of sorts. I was told that one of the first programs that EDSAC ran printed out a table of integers and their squares. This did not impess other academics at Cambridge very much, because squaring was fairly easy to do on an analogue machine (so why bother with the more complicated digital ones?) The second prgoram printed out a list of prime numbers. Other people were impressed. Doing that was very difficult on an analogue computer, so here was something the digital machine could do that the analogue one couldn't. -tony From ard at p850ug1.demon.co.uk Wed Sep 7 12:51:04 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Wed, 7 Sep 2005 18:51:04 +0100 (BST) Subject: Homebrew Circuit Boards: Methods?

The developer (as opposed to the etchant) is generally just a strong alkali. In the UK, sodium hydroxide solution is commonly used, it's sold (pure enough for PCB developing) for cleaning drains.

While trying to connect my PDP-8/L to the PC04 fast reader/puncher, I realized that the schematics for the M705, M710 and M715 card posted by David Gesswein http://www.pdp8.net/pdp8cgi/query_docs/queryb.pl?level=1m-series;id=689 did not correspond to the ones I have. These are late "F" versions (1971). These cards include several DEC9801 one-shot TTLs as well as 7475 TTLs. My cards are 1969 versions and have no 9801 nor 7475. My cards have been somewhat modified by the former owner of the PDP-8/L. I have to understand what he did in order to repair them (most cards have to be repaired because an overvoltage episode killed about one third of the TTLs in my PDP-8/L) ! Many thanks, Philippe .

These are mostly more recent models but there are some going back into the II series. All these systems are in anywere from good to poor condition, with the majority being in good condition. Most are complete, but I haven't looked inside, and I haven't powered up anything. Some are yellowed. Some are pristine. If you're interested in a particular model, ask and I can tell you the condition. In some cases there are multiple units of the same model, with the condition varying among them. Here's the deal: 1. $10 each plus shipping. 2. If you want me to inspect any system for any reason (other than reporting on general condition), add $10. 3. If you want me to test a system, add $25. "Testing" will consist of turning it on and seeing if it boots into an OS, or in the case of older systems with no internal hard drive, I'll turn it on and see if it goes "boop!" 4. Take the entire pallet (55 computers total) for $100 plus freight.

Message-ID: <200509071704.19422.lbickley@bickleywest.com> For the second time in years, I've obtained a copy of the SGI Hardware Developers Handbook, Release 2.0 (05/97). This book covers all SGI products from the earliest Personal Iris through the Origin 2000/Onyx2. It details Chassis; Interfaces (serial, keyboard, mouse, parallel, disk drive, monitors, memory, graphics, video, audio, CPU, Bus, backplanes, network connectors, I/O Panel Plates, Drive Sleds); "hinv" output descriptions (complete); Software & Hardware tools, etc. This book was created for SGI hardware designers - but is a terrific source of information for all SGI buffs and collectors. The copy I picked up years ago is worn from a great deal of use!!! The copy I just obtained is brand new - with no markings or scratches other than one very minor nick on the bottom of the front cover. Before I put it on "ePay", I decided to offer it to this list first via the Vintage Computer Marketplace: http://www.vintagecomputermarketplace.com/bid.cfm?ad=2009 I normally would not post my own auction item on this list - but this is one of those great finds that one seldom gets an opportunity to pick up...

I didn't regret my > purchase one iota, btw.) Not much of a market for old Macs these days. A month or so ago I was looking for a Quadra 950 PS for my 2nd unit and a guy close to Cleveland said he has a parts 950 I could have if I drove up and got it (about an hour away). So I drove up there (grabbed the yellowing 950) and he started giving me other stuff like a brand new looking AWS 95 that was never used and included the full still sealed A/UX 3.x software set with manuals and it had the rare 5 drive tray inside also (all free). Same guy was selling an early PPC with monitor for $50 (no I didn't want it). I can see nobody wanting a skid of old Macs (most people just want a specific model), did you keep the machines or resell them individually on ebay? Still if you need a specific machine $10 plus shipping isn't that bad (even that is probably not worth Sellams time to box up).

The problem with $10 mac's is $0 software. With a old PC you could steal DOS and BASIC from good old Gates. :) They still may be usefull for parts like CRT's and 68000's for the really old mac's.

Apple has lots of older System versions for download, and it's not that hard to find more recent versions of MacOS used. -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

He's a Mac lover and part of the 'plus' in sending home targeted Macintoshes is that the kids won't 'goof off' with Windows games on them, or so he said. I got a tidy little profit plus a school teacher got the hardware he needed for his personal 'mission.'

In general it is easier to find boxed Mac software (atleast for me) then to find the same software for the PC. Do Mac people keep their older software while PC people tend to throw it out or something? Mac OS 7.01 and 7.5.x is available free from Apples website, I don't think any MS versions of DOS or Windows are available for free download (ofcourse they are available on the net for pirating).

Upgrades includes a G3-400 1MB Cache, USB Card, ATA/66 Card with 2 x 10GB IDE drives and a 40X cdrom. In general its used for supporting my other Macs, some web use, and older PPC software I want to mess with. My favorite Macs would be a tossup between my IIfx, 840AV, and AWS95.

Second tier airlines (then again, these days what's the difference), but pretty cheap considering the payoff once you get to VCF. Of course you have to drive from Hibbing (childhood home of Bob [Zimmerman] Dylan, by the way) to the big city first, which is a bit of a trek, but there's always Camp Snoopy at Mall of America to even further justify the trip.

Hmm, I'd definitely prefer to drive I think - way more fun that way :) I could buy a car and then sell it again afterwards as that'll likely work out cheaper than renting (hmm, need to check on my insurance though - I know it covers me for any vehicle in the UK but not sure if that extends to overseas trips or not). I found a '66 Mustang the other day which I'm seriously tempted with... Only spanner in the works is that it's the girlfriend's birthday on the 6th and I don't think she's going to be too happy if I'm halfway across the country at the time!

Hey, all you need to do is to abolish the stupid law, that US airlines can only be owned by US citicens/companies. By now United is basicly owned by lufthansa, Northwest is, if I'm correct, KLM/Air France, and was it Delta where the Brits had their hands on? By abolishing that law, the airspace would be quite fast reordered. > I'm trying to get a flight to Vienna and prices are all over > the place...above $2,000! Ridiculous.

I would guess you can apply a 5 bit address and read the contents of that location one the DO lines. You may have to pulse the strobe line, or something like that.

As some cctalk'ers know, we've got a club here in the mid-Atlantic region called MARCH -- Mid-Atlantic Retro Computing Hobbyists. Yes, we know it's dorky name, but it's easy to speak and explain. We are temporarily based in a Yahoo group at http://groups.yahoo.com/group/midatlanticretro/ and we've got a real site under construction. Our club's first event was a kick-ass exhibit at the Trenton Computer Festival's 30th anniversary show in April. We emerged from TCF with enough confidence to ask Sellam for the right to host VCF East 3.0, and he consented. We're planning it as a one-day show sometime in March 2006. We haven't discussed an exact date, but I imagine we'll aim for the end of the month, to hopefully avoid snowfall. The venue will probably be the InfoAge Learning Center, located in Wall, N.J., by the shore. Wall is located about one hour east of Trenton, one hour north of Atlantic City, and 90 minutes south of Manhattan. By train, you can take the Amtrak from Trenton to AC, and then rent a car, or take NJ Transit from Manhattan directly to Wall. You can also fly into Newark or Philadelphia, or get a smaller plane to Trenton or AC. By car, Wall is right off of two majors highways (I-195 and the Garden State Parkway). It's the red star on the map at http://tinyurl.com/cj8kp Our club is currently forming a computer museum at InfoAge's facility. For details about InfoAge, which is extremely "under construction", see http://www.infoage.org -- we're inheriting their existing computer collection which even includes a small part of the ENIAC. Side events to our edition of VCF could include a tour of Camp Evans (the former Army radio research center which is where InfoAge is based) and a Nerd Trivia Contest. At http://www.visitmonmouth.com/tourism/attractions.asp you can find general tourist information about the region. Comments / suggestions are welcome. Better yet, if you live in the mid-Atlantic region, check out MARCH. - Evan K. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Eric Chomko Sent: Wednesday, June 29, 2005 11:35 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Washington Post article on Classic Computers Yeah, the article was great!

Well, I did manage to make a microcode simulator and it boots the lisp machine. I think there are a few very subtle bugs in the pipe, however, and I think the only way I'll find them is to watch the real hardware work. I think the timing on this machine, and the 74S/74LS parts it uses are slow enough that verilog will do fine. In reality what I am saying is not about verilog, but the accuracy of the models I have created. So, restated, I think I can make models which are accurate enough for this type of design. heh. we'll see. -brad From bfranchuk at jetnet.ab.ca Thu Sep 8 17:30:46 2005 From: bfranchuk at jetnet.ab.ca (woodelf) Date: Thu, 08 Sep 2005 16:30:46 -0600 Subject: datasheets for 82S21 - Signetics 32x2 SRAM?

Those will work, but I think those are the leads for an H901 based Logic Lab, as opposed to the (non-stackable) leads for an H500 Computer Lab. (The patch-cords you have pictured look like H911 patchcords.) The brass rivets/grommets/jacks are the same size, so either type of lead will work fine in either lab. Stackable mini-banana plug patch-cords are still made, and work OK in either. What I did was buy a set of mini-banana to regular-banana adaptors, which I got a good deal on, and a bunch of stackable regular-banana patch-cords, which were also inexpensive. I'd love to have something closer to the original patch-cords, though :-). > If anyone has a spare manual, I'll trade a handful of leads for it! > Otherwise, I'm in line with everyone else hoping for a good scan.

Discrete electronic components are rarely a problem, even coils and transformers could be replaced. More difficult are certain kinds of integrated circuits. The mentioned 7480 is maybe hard to locate even as a datasheet (good idea to keep old TI TTL databook, IIRC also at bitsavers), and even more difficult to locate the chip itself, but this is a function that would easily fit into a GAL. A real problem are species what can't be simply replaced by some GAL, namely open collector components or "extendable" gates like the 7450. Replacing a single chip of such a kind usually means replacing its environment as well, e.g. that 7450 would then require to pull the extension gate (was it 7460, my memory is failing) as well. In the area of unobtainium, however, you usually don't find SSI or MSI circuits, but rather nasty special analog circuits and early LSI MOS circuits. Often a modern uC could emulate the latter, but this often needs significant tinkering for each problem, and an many cases also rewiring its environment. Surely the question original replacement vs. reengineered functionality has some religious aspect, but if it is the question of whether an old system should be left inoperable in a museum in contrast to actually switching its blinkinligths I favor reengineering.

Two ideas come to mind - lighting gels, used in stage lighting, and Kodak makes lens filter gels in a huge range of colors. Both these items will appear to be colored sheets of plastic. In the case of the Kodak product, the "pass band" of the filter will be narrow and precise (an exact shade of a certain color and it won't pass much else).

Message-ID: <200509090717070826.001F9809@192.168.42.129> Fellow techies, I've been asked, on behalf of a friend of mine (John Lanfri), who does not have reliable Internet access at this time, to assist in finding those interested in acquiring a goodly collection of DEC'ish (pre-HP, pre-Compaq) hardware, software, and docs, along with various other Classic-era stuff which has yet to be unearthed. This may, depending on what he's getting rid of at the time, include such things as a fully-loaded PDP-11/34 with all docs, including field service prints, RSTS/E, spare disks (RL02's), TU10's, etc. It may also include an 11/73, rebuilt tri-density 9-track drives (I don't recall if they're Fujitsu or NEC, but I do recall that they've not been used since being refurbed), SMD disk drives, large and small, and other goodies too numerous to list. This project is long-term. It is expected to take place over the course of the next six months to a year. An inventory will be generated within the next couple of months. Shipping will NOT be available. Period. This will be exclusively local pickup in the San Jose/Santa Clara CA area. WHAT TO DO FOR NOW: Along with the inventory, we're working on generating a contact list. If you're interested in being kept up to date on this project, and would like to be among those offered the opportunity to acquire, please indicate as much in a private E-mail note to me, and please include a contact phone number. Either John or myself will contact those interested with further details of what's become available at what time. PRICING: I can't speak for John, 'cause it's all his stuff, but I will say that he's not going to gouge anyone. He's indicated to me that he's more interested in getting the stuff to those who can appreciate and use it than he is in making a fortune from it. Pricing for each item, or set of items, will be shown on the inventory. Some items may be tagged as 'Make an Offer' (which you should also do if you don't like the price shown -- John is an astute bargainer). ;-) Again, please remember -- BAY AREA LOCAL, or those who would be willing to drive to San Jose/Santa Clara ONLY. Shipping will NOT be available, and you may need (at minimum) a pickup or flatbed truck for some items. This will be noted on the inventory if a given item or set of items warrants it.

The ET-3400 has no bezel around the TIL-312 displays. The red filter material provided by Heathkit was pre-cut to the exact size of the face of each display, and sticks on by its own adhesive. It seems to be quite soft (vinyl-like as opposed to mylar-like) and quite thin - much thinner than scotch tape.

I am thinking about maybe tail light repair tape used on cars. It is red, thin, fairly opaque in appearance (but allows the light through)and is self adhesive.

I have one (and the STG1861). The Elf 2000 is assembled and works great. I'm verifying my disk I/O board (8-bit CF interface plus Dallas clock chip plus 16450/16550 UART) right now. I am out of ancient/recycled 22V10 GALs and am having problems getting set up to burn modern Atmel ATF22V10s, or I'd have a working STG1861 by now. One of my short-term project goals is to get ElfOS up on the Elf2000, then to get Zork running on it (using Mike Riley's 'zrun3' program I helped him debug). If you want a full-featured 1802 machine, I can totally recommend the Elf2000. It was easy to assemble and works great. -ethan From ethan.dicks at gmail.com Fri Sep 9 13:52:30 2005 From: ethan.dicks at gmail.com (Ethan Dicks) Date: Fri, 9 Sep 2005 14:52:30 -0400 Subject: GPIB state machine info WTD In-Reply-To: <200509091706.KAA05774@clulw009.amd.com> References: <200509091706.KAA05774@clulw009.amd.com> Message-ID: On 9/9/05, Dwight K.

One issue is to identify what GPIB devices you expect to talk to. Older ones, especially ones that implemented the protocol via ~1MHz 8-bit microprocessor, are unlikely to be able to handle 1MB/sec speeds that the newer "IEEE 488.2" devices can. If all you want to do is talk to old devices at a few KB/sec, it really doesn't matter if you have a hardware or a software implementation. For the newer, high-speed stuff, I'd expect you'd need an ASIC to pump the bytes through in a timely fashion. OTOH, even Commodore had a little fiddly hardware thing to handle handshaking turn-around. Andre Fachat mentions that in his extensive pages covering Commodore hardware and his own home-built mostly-PET-compatible 6502 computer. I do not know about the Commodore acoustic couple (C810?), but disks and printers tended to have 6502/6504/etc software implementation of GPIB. -ethan From Richard.Cini at wachovia.com Fri Sep 9 14:17:42 2005 From: Richard.Cini at wachovia.com (Cini, Richard) Date: Fri, 9 Sep 2005 15:17:42 -0400 Subject: GPIB state machine info WTD Message-ID: If you can find it, get a ROM dump or listing from one of the floppy drives like the 2031LP disk drive or the 2040 dual-drive.

Anything else is incorrect. I ment accurate in two ways. First, correct behavior (which is not as easy as I thought it would be) and second, "reasonably close timing". I initially added delays to match the original ttl parts but I've since backed off a bit and only added them in the memories. >I hope you are not trying to do timing verification with verilog modeling? No, not timing verification, but the design has some timing dependancies - mostly in areas of long propagation delays (i.e. slow parts caused problems). Once I have the original netlist working I plan to rewrite it in a more modern "vector" style, mostly for fun and as a learning exerience.

Well, Titmouse is a perfectly respectable term: http://en.wikipedia.org/wiki/Titmouse These birds are called "chickadees" (derived from their distinctive "chick-a dee dee dee" alarm call) or "titmice" in North America, and just "tits" in the rest of the English speaking world. The name titmouse is attested from the 14th century, composed of the Old English name for the bird, mase (Proto-Germanic *maison) and tit, denoting something small. The spelling was influenced by mouse in the 16th century. "Chickadee" is onomatopoeic, i.e., sounds like the call of many North American species. And certainly, "tit" denoting something small certainly applies to the laptop titmouse. - Joe :-) From brian at quarterbyte.com Fri Sep 9 18:45:36 2005 From: brian at quarterbyte.com (Brian Knittel) Date: Fri, 09 Sep 2005 16:45:36 -0700 Subject: PDP-8 in Volkswagen Message-ID: <4321BC30.30316.8DF918D9@localhost> Hi, First off, thanks to all who replied to my earlier question about the history of the CP/M BIOS.

I've got a Toshiba T2130CS here that does the same thing. My mum's got a Compaq Evo N600C (weird thing - has a TrackPad and the Accupoint "tit-mouse") that does it too. I think it's some form of auto-calibration system, though it seems to screw up a lot more than I'd like. Thankfully Trackpads aren't anywhere near as bad (IMO). Not as good as a mouse, but good enough for computing on the go. Seeing as we're on the subject of laptops, does anyone have any Panasonic CF-VZS251 (I think that's the right part number...) batteries lying around? I've got a CF-25 Toughbook here that seems to have a duff battery (I'm getting about an hour out of it - it's a very old Li-ion). Either the Li-ion or NiMH version would be fine (though I suspect it'll be easier to get high-capacity NiMH cells than bodge some 18650 LiIons to fit).

What I'm wanting to do is implement a slave device - in this case it'll be a data logger. The problem is, I don't want to end up tying up CPU resources monitoring the bus - it's going to be sharing the bus with a multimeter, a logic analyser and (if I ever get off my BFA and build the damn thing) a power supply. What I'm after is some way to receive data bytes into a buffer, then do some address-comparing and only interrupt the CPU if data arrives after an address match is detected. Most of the logic seems to be along the lines of (going from memory): ALWAYS @(posedge data_arrived) IF ATN = 1 THEN IF data_byte & 0xE0 == 0x20 THEN // TA IF data_byte & 0x1F == my_address THEN // Talking on CAN_TALK = 1 ENDIF IF data_bute & 0x1F == 0x1F THEN // UNTalk CAN_TALK = 0 ENDIF ENDIF // ... same sort of thing for Listen Addressing ENDIF END ALWAYS The problem is working out how to rig up a state machine or something similar to handle the handshaking... Trust me, if I had any spare MC68488s or similar, I'd use them. I've got some Fairchild 96LS488s, but no data at all. Finding a datasheet for the 96LS488 seems to be about as easy as finding 99.9999% pure Unobtainium. For master-side addressing I'm going to use the PC and a CEC GPIB card. Speed is not the big issue here - I'm doing this mostly for the "fun project" aspect. My idea of fun is, unfortunately, somewhat warped...

Replacing a single chip of such a kind usually I hate to tell you this, but the 7480 will not fit into a GAL. The A* and B* pins are effectively open-collector I/O with intenral (6k) pull-ups. You can extend the input gating via that pin, or you can monitor the output of the A1/A2 NAND gate there. > means replacing its environment as well, e.g. that 7450 would > then require to pull the extension gate (was it 7460, my memory is > failing) as well.

Me too. Computers that don't work are not interesting. That said, I am in favour of doing as few mods as possible to the original machine. For example, I'd fit a turned-pin socket in place of the original chip and wire up a heeader to the replacement chip (maybe using stripboard or a PCB to make a plug-in module). That way, if I ever get the real part, I can go back to the original design. -tony From ard at p850ug1.demon.co.uk Fri Sep 9 19:31:10 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Sat, 10 Sep 2005 01:31:10 +0100 (BST) Subject: VMS Question...

Be _very_ careful if you use designs intended for the PET. The PET was very forgiving in the timing of the peripherals. I have a commercial PET RS232 interface that contains a UART chip, RS232 buffers, a few TTL chips as SR latches to hold the talk and listen states, an EPROM as the code converter (PERSCI-ASCII) and talk/listen address detector) and another EPROM as the handshake control logic. Due to the fact there are no latches in the latter section, the timing goes all over the place. It works on the PET, it doesn't work on any HP machine I've tried it with. -tony From curt at atarimuseum.com Fri Sep 9 21:15:18 2005 From: curt at atarimuseum.com (Curt @ Atari Museum) Date: Fri, 09 Sep 2005 22:15:18 -0400 Subject: mouse nipples In-Reply-To: <4321F165.8050102@yahoo.co.uk> References: <4321F165.8050102@yahoo.co.uk> Message-ID: <432241B6.7030703@atarimuseum.com> Mouse nipple... thats a new one...

Perhaps 780s just don't break :-) Realistically 11/780's are now of an age that contact reliability for all those cards is the biggest issue. 4000-60's aren't spring chickens either but they have a lot fewer components and way way fewer sockets/contacts. I've done component-level repair on both 11/780 systems and 4000-60 systems but it was always at the line-driver/memory chip level, i.e. parts that are very easy to isolate and diagnose often through the very process of swapping out stuff at the board-level. VAX6000 systems are probably the ultimate in over-engineering for reliability and although they've got a lot fewer boards than a 11/780 they still have some BI-bus contact reliability issues despite a much slicker edge connector and less age.

There is no CPU involved in this serial adapter. The EPROM is the logic for the GPIB handashake. It's the GPIB timing that's way out. It works with a PET as the other side of the link because the PET does all the handshaking in software, so it's pretty forgiving about timing problems. But this seiral adapter will _not_ with, say, a 9914 as the other device on the bus.. -tony From swtpc6800 at comcast.net Sat Sep 10 20:28:35 2005 From: swtpc6800 at comcast.net (Michael Holley) Date: Sat, 10 Sep 2005 18:28:35 -0700 Subject: SWPC Digi-Vista Nixie Clock Message-ID: <001d01c5b670$2b769030$0300a8c0@downstairs2> I finished my Nixie tube clock.

My old brother had that mag and I would always borrow it. I just dug out my SWTPC 6800 (both) from the garage this past summer. An old buddy let me have these way back after he was tired of it. This also came with the docs and a bunch of boards too. I hope I can ping some questions to you when I'm working on this. Right now, I'm getting our Altair 680b he bought back then restored plus some other machines.

I have an early one, but seeing pre-production hardware would be cool. For those that might not remember earlier tales, my first job ever was programming the WordVision demo for Bruce and James Publishers on a pre-public-release development machine from Commodore.

You haven't worked on the 86x0 systems, I can hear... The 6000 series are a joke in comparision. The 86x0 systems are designed to continue to work even when chips actually don't work. Those faults are logged, alternate signal paths are activated, and the board should be scheduled for replacement at the next normal PM. So yes, there are double sets of registers, paths, and whatnots, so that most faults actually don't stop the machine from running.

HP 7914 hard drives to UK spec. This involves not only changing the input tappings from 110 Volts to 240 volts but also changing the main drive pulley and drive belt to compensate for 60 Hz / 50 Hz mains frequency difference. Machining up a revised (larger) pulley isn't a problem but finding the drive belt is proving difficult. Is there anyone on list that has the necessary parts (perhaps a scrapped drive in the UK)? I think that the parts are common for the 7911, 7912 and 7914 drives - the HP part number for the belt and pulley are - 07912-20013 (pulley) and 07912-40018 (drive belt). Does anyone have experience of these drives? The pair that I have are quite grubby on the outside, have probably been knocked about a bit in transit but have had the spindles locked and the head leaver in the 'locked' position - is it likely that they will still work?

Well, darn it, they aren't linked. It turns out that the memory controller on the IIfx buffers the writes, so that the CPU can go do something else after only 2 cycles instead of 6, unless, of course, the next operation is a memory access. So the the data lines from the SIMMs are routed to 74F573 D-type latches. It appears that the SIMM's DIN comes from the latches' outputs and DOUT goes to the latches' inputs. I have not confirmed it yet (must pull the PGA 68030 to get access to the data lines) but I suspect that the bidirectional databus goes to the input lines of the latches. So, on a read, the data would just come out of the memory straight to the bidirectional data bus. On a write the data bus would take data to the latches' inputs where it would be buffered, and the memory controller presumably has control of the LE (latch enable) and OE (output enable) lines to the latches. So, if I tied DIN and DOUT together, it looks like there are at least two potential trouble spots. 1) If the memory controller does not switch the latches to High-Z (OE inactive) upon completion of Writes, then on a Read, the data from the memory would be in contention with the data still held by the latches from the previous write. 2) While the memory controller is buffering a Write, that data would feed back from the latches, along the tied together In and Out to the bidirectional data bus. So, for example, the CPU signals a Write. The memory controller takes over, and the data is buffered and held in the latches. The CPU is done in 2 cycles, but the MC will need 6 cycles total to complete the write. Now the CPU goes off to do something like an IO operation during which it will also need the data bus. However, because the In and Out pins are tied together, the bidirectional portion of the data bus is being fed the data from the previous Write operation for four more cycles while the memory controller completes the write operation. This will interfere with any other use of the data bus. So unless the data bus to the memory is seperate from the data bus to the rest of the computer, I believe that tieing the In and Out pins together will screw things up. Does my reasoning seem sound? What did I miss? Was that clear?

Okay, what if I put a pair of octal tristate buffers on the SIMM and control them with the Write Enable line such that data can go from DIN to the DRAM chips' data pins when WE is active, and data can go from the chips' data pins to DOUT when WE is inactive? Something like the SN74ABT541 looks like it might do the trick: I see two potential problems. First, the buffer will introduce about 4 ns (max) of delay between WE changing and data flowing, so timing might be dicey. Second, the timing will be even tighter, if the computer tries to do a Read Modify Write to memory. So one important question is whether the IIfx makes use of the Read Modify Write function of DRAM. Checking some old datasheets, it appears that that feature was present in old DRAM chips. Did computers typically make use of it? The tristate buffers are only about $.50 each, so they don't add much to the cost, but they might blow the timing.

If you read the PE article you would have seen that an alarm feature and means of implementation was described. > I would have updated the high voltage power supply to a simple > transistor regulator.

I'm sure the nixies can handle any 128 VAC generated "over voltage" condition that may be inherent in the original design. BTW, is that 128 VAC your actual _RMS_ AC voltage? d8^) > PS.

I know there >is an "options and adapters" series, but what else is there? FYI I have one new package here and it's binder is marked "IBM Personal System/2 Hardware Maintenance Service". It includes two plastic sealed packs of pages ~1/4" thick. One has the same name but it's number is 80x0880. The 2nd pack isn't titled but the top page is titled "Hard Tab Installation". It's number is 80x0882. There's also a 3.5" disk in the binder that's titled IBM Personal System/2 Model 50/60 Reference Diskette. PN 15F1045. The binder is marked 68X2222 and S68X-2222-00. I have others but they're all packed away. > >Oh, and if anyone is junking a PC-1 (black power supply, 16-64KB >motherboard), I'll take it :-) Those are getting VERY hard to find around here. I picked up a nice one about 3 years ago and found a beat up one about a year ago (rescued for parts) but those are the only ones that I've seen in about 4 or 5 years.

So this is a windows feature too! I favor OS/9 for the 6809 a very nice OS and on topic too. :) I think most OS's lost it since all computers have gone graphic rather than text.

I know there > is an "options and adapters" series, but what else is there? > There is the 'IBM Industrial Computer' technical reference manual set. It's in an 8-1/2" x 11" looseleaf binder. The Industrial Computer was essentially a PC-XT in a rackmount industrial case. So the techref details include schematics of all the standard XT components. There was a pile of Industrial PC techref sets at a surplus store I used to visit in the late 80's, that is where I got mine. I guarantee they aren't there any longer. Also, the early Compaq manuals are worth gathering up. I have the Compaq Deskpro 386 manual, which is of historical significance because the Compaq 386 came out before IBM made a 386 machine (people more expert than me can correct me on this if I am wrong) I have the IBM PC-1 era Technical Reference Manual, which my father ordered when he bought 'the whole package' of the IBM PC and pretty much everything for it at the launch of the PC-1, at the IBM Employee's discount. Sadly, there was an era in the past where I got involved in a strong conflict with a landlord over all my 'junk' when I ceased to own the whole PC-1 itself. One of my bigger regrets with regard to collected hardware is that I no longer have that machine. Now I have far less worthy machines all over this (owned, not rented) house taking up much more space than that system. > Oh, and if anyone is junking a PC-1 (black power supply, 16-64KB > motherboard), I'll take it :-) *sigh* From chenmel at earthlink.net Mon Sep 12 18:26:55 2005 From: chenmel at earthlink.net (Scott Stevens) Date: Mon, 12 Sep 2005 18:26:55 -0500 Subject: Various Macs for Sale In-Reply-To: <6.2.5.1.2.20050907235048.033f7108@boff-net.dhs.org> References: <431FA38F.6090607@jetnet.ab.ca> <6.2.5.1.2.20050907235048.033f7108@boff-net.dhs.org> Message-ID: <20050912182655.55945950.chenmel@earthlink.net> On Wed, 07 Sep 2005 23:52:51 -0400 John Boffemmyer IV wrote: > I may sound like a dick for saying such, but if the OS is missing and > price is an issue, there's always Linux and several other OS'es that > work fine on Apple products.

I have it installed on one of my SE/30's, which is the oldest Apple hardware I have run it on. The little one-bit display is a bit limited for X11 but with the Tab Window Manager it's actually somewhat usable. The SE/30 is also nice because you can put a lot more memory in it than any other 'classic' Mac. 32 megs is trivial, and if you chase down 30 pin 16M SIMMs you can put 128 Megs in an SE/30. > PS: I always hated OS9 after it corrupted itself on my ex's mac and I > had to spend a week reloading the damned thing. > > At 11:35 PM 9/7/2005, you wrote: > > >On Wed, 7 Sep 2005, woodelf wrote: > > > > > The problem with $10 mac's is $0 software.

I've had an SE/30 for about 10 years (it was the first Mac I've owned with a SuperDrive), but I've never been able to lay my hands on any 30 pin 16MB SIMMs... they are rarer than 72 pin 36-bit 32MB SIMMs for sun4m machines (SPARCclassic, LX) - _those_ I've been able to track down to max out an LX or two. At least one doesn't _need_ 128MB on a 68K Mac running MacOS, unless you are doing a lot of Photoshop work - then, I'd recommend a newer machine anyway, one with color, like a Mac IIci w/cache card. -ethan From ard at p850ug1.demon.co.uk Mon Sep 12 17:48:19 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Mon, 12 Sep 2005 23:48:19 +0100 (BST) Subject: 64 pin SIMM (Mac IIFX) Specs?

The outputs of those latches would then be contending with every other device on the bus. I think it's unlikely those latches are ever tri-stated in normal operation unless some other device can drive the DIn of the RAMs -- and what would that device be? -tony From ard at p850ug1.demon.co.uk Mon Sep 12 18:12:13 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Tue, 13 Sep 2005 00:12:13 +0100 (BST) Subject: Looking for IBM PC/XT/AT technical references In-Reply-To: from "Richard Beaudry" at Sep 12, 5 03:06:08 pm Message-ID: > > Hello all, > > My latest "refocusing" of the collection is on IBM PC hardware > (PC/XT/AT, original IBM cards, peripherals, etc.) and on software IBM > sold for the PC line.

Ones that I know exist (these are not the official titles, I can get those if you need them): PC TechReF PC/XT and Portable TechRef PC/AT TechRef All those existed in at least 2 version : Early ones had information on the expansion cards, later ones only had information on the motherboard, PSU, keyboard. The expansion card info got moved to the Options and Adapters TechRefs Early PC/AT TechRefs cover the 6MHz system only using those 128K 'piggyback' RRAMs (2 64 K bit chips with strange pinouts soldered together), later ones also cover the later mainboard using 256K DRAMs, and the 8MHz clock version PC/jr TechRef. I've never seen this without the peripheral information included. Options and Adapters TechRef. The 'base version' of this is 2 binders. It contains info on the 8-bit I/O stuff only -- the expansion unit, expansion cards, monitors, drives, printers, etc. There's a suplement for the AT expansion cards (combined serial/parallel card, combined floppy/hard disk controller, 16 bit memory expansion cards, etc) There are many more suplements for later add-ons. One particuarly complete one is the EGA technical reference. Scientific Options and Adapters TechRef. Covers the Professional Graphics controller, GPIB card, Data Acquisition card. There must have been a TechRef for the XT/286, it's about the only one I am missing. PS/2 Hardware Interface TechRef. This is a pale shadow of the earlier ones. No scehamtics, no BIOS source. But better than nothing. There will have been HMS manuals for all the PC family machines. I can't see the use of them -- the information _I_ need to fix the machine is in the TechRef. -tony From spectre at floodgap.com Mon Sep 12 18:54:03 2005 From: spectre at floodgap.com (Cameron Kaiser) Date: Mon, 12 Sep 2005 16:54:03 -0700 (PDT) Subject: Various Macs for Sale In-Reply-To: from Ethan Dicks at "Sep 12, 5 06:47:07 pm" Message-ID: <200509122354.QAA13238@floodgap.com> > I've had an SE/30 for about 10 years (it was the first Mac I've owned > with a SuperDrive), but I've never been able to lay my hands on any 30 > pin 16MB SIMMs Eh? I bought eight of them for my IIci from memoryx (www.memoryx.net). I'm sure other places carry them, too.

Memory upgrades for older hardware is always problematic. I would love to have more memory in my Powerbook 165c, but it's very proprietary.

If you don't want to scrounge surplus stores, or wind your own, Hammond currently makes a couple that would work. They are the 269BX and 369BX, depending on whether you want "universal" primaries or not. Their high voltage secondaries are 300VCT, and they also have the 6.3V windings. They're a bit larger than necessary, being rated for 2-3 times the power called for in that design. allan -- Allan N.

You would probably manage it with a mains transformer used backwards, running off the logic supply transeformer : Suppose the logic supply transformer has a 9V secondary. Get another, smaller power, mains-to-9V transformer (say use 50VA for the first one, 20VA for the second, those are likely to be overkill). Connect the 'secondary') of the second, smaller, transformer to the secondary of the first one (which still supplies the logic PSU circuit). That second transformer will acts aas a step-up transformer, and will give you something a bit less than mains voltage across what was originally its primary winding. And of course that's totally isolated from the mains. If you manage to get a transformer designed for 230V mains for the second one (or one with 2 115V 'primaries' that you can connect in series), then just rectiying it would probably be OK for the nixie tube supply. If you can only get one with a single 115V primary, you could use a voltage doubled rectifier. Either way you'll end up with something over 300V DC -tony From ethan.dicks at gmail.com Tue Sep 13 15:36:56 2005 From: ethan.dicks at gmail.com (Ethan Dicks) Date: Tue, 13 Sep 2005 16:36:56 -0400 Subject: Looking for IBM PC/XT/AT technical references In-Reply-To: References: <43263F67.90708@nktelco.net> Message-ID: On 9/13/05, Tony Duell wrote: > > >However I did find three IBM marked FH Tandon TM-100 5 1/4" disk drives > > >last week :-) > > > > > Are those special?

For those that are considering moving floppy drives from one machine to another, just remember that there are single and double-sided versions of the TM-100 (various models from the TM-100-1 through the TM-100-4). As long as you match up the model numbers (the TM-100-2A is probably what you want for an ancient PC), the logo on the face plate has no influence on what the controller does to the drive (i.e. - there are _no_ electronic differences between an IBM-badged TM-100 and the same drive with a plain faceplate). I only say that because I've seen single-sided TM-100s (TM-100-1A) in CP/M machines. They should work with an IBM 5150 PC, but, naturally, only as single-sided drives, at a nominal 180K under DOS 2.1 and newer (9 sectors per track vs 8 sector "160K" disks in the earliest examples). -ethan -ethan From esharpe at uswest.net Tue Sep 13 16:42:00 2005 From: esharpe at uswest.net (Ed Sharpe) Date: Tue, 13 Sep 2005 14:42:00 -0700 Subject: DEC Computer Lab References: <18583518.1125709413708.JavaMail.root@elwamui-polski.atl.sa.earthlink.net> Message-ID: <005401c5b8ab$f9809880$4291a8c0@emachine7331> scan it and lets put it online hen easy for anyone to load it down. there is room on our server for a pdf scan of it.... contact me off the email on www.smecc.org I seldom use this email address these days. ed sharpe archivist for smecc www.smecc.org ----- Original Message ----- From: "Ashley Carder" To: "General Discussion: On-Topic and Off-Topic Posts" Sent: Friday, September 02, 2005 6:03 PM Subject: Re: DEC Computer Lab > >>> Dear Ashley, > >>> > >>> Yes, I have them.

From ajp166 at bellatlantic.net Tue Sep 13 17:49:58 2005 From: ajp166 at bellatlantic.net (Allison) Date: Tue, 13 Sep 2005 18:49:58 -0400 Subject: SWTPC Digi-Vista Nixie Clock Message-ID: <0IMS00HKQ22JLWA2@vms046.mailsrvcs.net> Top posted for brevity. Most equipment I've worked with run 160-190V for Nixies. Further my Yaesu YC-355D freq counter that I purchased in 1973 is nixie based and also uses around 170V. FYI: base logic is venerable 7490, 7475 and 7441 for the decades. For a simple PS to run nixies (and valves) I use a 6.3V CT 600ma or 1A To 117V mains transformer. They are common here in the USA and cheap. I drive them with a pair of bipolar power transistors in TO220 cases from 12V. Base drive for those transistors is derived from a squarewave source of two phases 180 degrees (555 and 7474 work fine) at 400hz or so (not criticial, higher makes filtering easier and less mechanical hum). The ouput can be rectified and filterd as needed (bridge or doubler is what I do depending on voltages needed). The voltage will be around 210V with a small load (10ma). If I need more power a heavier transformer with 3A or 5A 6.5V winding is used. Also if a stable voltage is needed sample the output and use that as feed back to a series pass feeding primary side power. That will regulate very well. I've built that many times and run many a HV device and even a CRT (D170 size) that required 1200V. For that I used a small 1A 10VCT:230V control transformer and a voltage multiplier and feedback for regulation. Works well. I prefer the driven style rather than self excited voltage converter as it's easier starting and has stable operation. It also doesn't require a special (hard to find or make) multiwinding transformer. the rest of the parts are also generally easily found in defunct stereos or even ratshack. Exotica and unobtainium is a pain.

This auction is for a "zukerboard" 576K mem expansion. 6801436037. I remember the hype for zucker that they were going to wreck the market. The only reason this has any significance is that I believe this was one of the AST wannabe's, or even was larger than AST, pre the days when they started making systems. I know of at least Zucker, Tecmar (marty tech, I don't remember marty's last name, but he was some sort of PHD ohio type, I think). A number of companies were based here in Orange County, California, and provided a lot of cheap stuff as they cratered, and the local scrappers got their. stuff and sold it off. Processor Technology (? I think) went big time and cratered. I remember a little shop here in Santa Ana which had the first clone of the IBM PC. It was a single board which had 640k memory, allowed using 64k memories, instead of the 16K memory that the PC and XT earlier models used. It was called "Superboard" and was no relation to Supermicro, which came much later. It had a bios that usually worked, but also had, conveniently, a spot for up to 6 eprom chips, so you could put in a PC bios if you could get a copy. The PC used either EProms, (16K I think) and the Roms that were shipped with the BIOS were registered. The standard Data I/O would not read them since they were not programmable, and needed their output enabled to read the data. But once someone had them in the 2716's, it was easy to get them running in your superboard. First systems had a 63 watt P/S, and IBM cards if you could find them for video. Also there was no floppy controller on the first board. Maybe others of you can recall expansion card makers, of such things as serial, parallel, memory, floppy, then hard drive, etc. Jim From ard at p850ug1.demon.co.uk Tue Sep 13 18:33:38 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Wed, 14 Sep 2005 00:33:38 +0100 (BST) Subject: Looking for IBM PC/XT/AT technical references In-Reply-To: from "Ethan Dicks" at Sep 13, 5 04:36:56 pm Message-ID: > I only say that because I've seen single-sided TM-100s (TM-100-1A) in > CP/M machines.

I had no RS232 or computer driven eprom programmer till much later when the Taiwanese programmer boards came out. Before that, I had only Data I/O 29b. Most distributors that you could buy parts from and beg the use of a programmer could not get the data into their programmers. So you carried the master parts and programmed blanks. anything else was a pain. I'm not talking about what you could do as a company with a budget. I'm talking about what you could do in your house when Data I/O was getting around $20000 for programmers, and $4000 for updates, and they were about all that there was out there. > > > > > First systems had a 63 watt P/S, and IBM cards if you could find > > them for video.

There's no mention of it in my TechRef. The original 5150, during 1981 and part of 1982 had one row of 16K DRAMs soldered in, and sockets for another three rows. Later, they switched to one row of 64K DRAMs soldered in, with sockets for another three rows. Some (all?) of those motherboards could be trivially modified to take 2 rows of 64K plus two rows of 256K.

I immediately started having second thoughts about the index hole after posting that comment. I never actually needed to 'notch' an IBM PC Diskette.

There was a cassette cable for less wealthy users. And on any IBM machine up to the late XT era, if you boot it up with no disk in the A drive or no floppy hardware at all installed, it will boot into 'cassette basic'. (does anybody know if the PC-AT had cassette basic resident in ROM?) My PC Convertable will do so. Sadly, you can't save or load anything into 'Cassette Basic' on the Convertable or models later than the PC as there's no cassette interface. I wonder if anybody has ever 'back ported' the Cassette port to an ISA bus card?? (not that it would help on the PC Convertable, of course.

Wasn't the pricing something like minimal equipment for $1695 or $1895, but about $5K with maxed memory and two floppies? I worked at Bruce and James Publishing when they released "WordVision" for the PC - I still have my free copy - the back of the package says "96K of RAM required. PC-DOS 1.0 or higher required. Floppy drive required." They felt it was necessary to tell the potential customer that they'd need a disk drive to use software distributed on disk. The real "problem" with WordVision is that it uses a software timing loop for key repeat. I ran into someone about 10 years ago selling ancient copies of it at a HamFest, along with a patch to disable key repeat. With that patch, it works fine on newer machines and newer versions of DOS. I _think_ it works OK on 386s and DOS 3.3, perhaps newer than that. Of course, without the patch, even breathing on a key fills the screen with unwanted keystrokes. Works great on a 256K 5150, though. -ethan From cisin at xenosoft.com Tue Sep 13 23:20:31 2005 From: cisin at xenosoft.com (Fred Cisin) Date: Tue, 13 Sep 2005 21:20:31 -0700 (PDT) Subject: IBM PC hacking In-Reply-To: References: <43276999.A056B9F0@msm.umr.edu> <20050913215917.0c1e8744.chenmel@earthlink.net> Message-ID: <20050913211609.Q13211@shell.lmi.net> On Tue, 13 Sep 2005, Ethan Dicks wrote: > [5150] > Wasn't the pricing something like minimal equipment for $1695 or > $1895, but about $5K with maxed memory and two floppies? $13xx !

It looks like they now have 6.4, but again can't distribute- it depends what you want to do (I can't remember what your project is) but 5.3 is definitely a more proprietary UNIX than 6.2+ is in terms of requiring IRIX specific tweaks and oddities.The upside, of course, is that your program will run on R3k (which can only run up to IRIX 5.3, generally, some IPs max out at 5.2, and the earlier machines really like 4.0.5 or less, which is even weirder to code for, especially 3.x [NeWS-based windowing system] (how's that for a run-on?)).

Well, of course you remember that back then disk drives were still a somewhat expensive option, and lots of software was being distributed on cassette back then, and it would not be obvious to the consumer whether they were buying software on disk or cassette unless the package told them. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ] From RMeenaks at OLF.COM Wed Sep 14 08:26:50 2005 From: RMeenaks at OLF.COM (Ram Meenakshisundaram) Date: Wed, 14 Sep 2005 09:26:50 -0400 Subject: Using SimOS to simulate a SGI MIPS IRIX environment Message-ID: <9A6FF2537AEA484296A3EE4990D18557545DDF@cpexchange.olf.com> Hi, I am currently porting the INMOS iserver program to work with some more modern processors and also revamping it to be a lot more modular.

After applying and exposing photoresist, one uses developer to remove the unexposed (or exposed for positive) photoresist without affecting the exposed (or unexposed) photoresist. After etching the excess copper away with an etchant, the polymerized photoresist is still present on the protected copper traces and must be removed using a stripper. So, when using a photoresist system, one needs developer, etchant and stripper. However, I suspect that the stripper, at least, may be some commonly available chemical such as acetone. And I believe that Tony mentioned that developer is usually just a strong alkalai. Thank you for the helpful information and for sharing your experiences. The supply source and books look interesting.

There are dozens of companies in that business. If you look in the back of any issue of EE Times, Electronic Products, etc., you will find the ads. I personally have good experience with PCB Pool (for a 4-layer board, not dense but with fine detail for surface mount parts). They are interesting in that they can accept not just Gerber files, but also Eagle CAD files, which are easier to work with if that's the tool you're using. (And a limited version of Eagle CAD is available for the download. It's pretty nice.) A lot of those outfits will do the cutting with a router to produce whatever board outline you need, which is good for stuff like SIMM boards. Gold plated fingers may be an issue, though; I haven't seen those. (Then again I wasn't looking for them.) Plain old tin plate may be ok. paul From bfranchuk at jetnet.ab.ca Wed Sep 14 11:27:52 2005 From: bfranchuk at jetnet.ab.ca (woodelf) Date: Wed, 14 Sep 2005 10:27:52 -0600 Subject: Homebrew Circuit Boards: Methods?

Sure. That wasn't a problem for me because I bought Eagle CAD way back when, before they had the free version, so mine doesn't have the limits. For that matter, if you spend some money that is still true. I don't know about free layout tools, much less free autorouters. Are there any? (The Eagle autorouter isn't all that good but it does get the job done, and you can easily clean up its output if you think it looks too ugly.) paul From jwstephens at msm.umr.edu Wed Sep 14 12:00:41 2005 From: jwstephens at msm.umr.edu (jim stephens) Date: Wed, 14 Sep 2005 10:00:41 -0700 Subject: IBM PC hacking References: <0IMS001I28LZXL72@vms046.mailsrvcs.net> Message-ID: <43285739.ACB8510F@msm.umr.edu> AST had the 1 millionth 6 pack in a display case in building 3, on their campus for a while, in the lobby.

Yes, those leads match the lab they are pictured with. To avoid confusion, I suppose we should call them "Computer Labs", rather than "Logic Labs", since DEC sold an older product as a "Logic Lab".

Well, it's almost ontopic - the printer's 7 or 8 years old, IIRC, and it's got plusses for 'kewl-factor'. ;-) Well, it *used* to... see below. I have a QMS MagiColor 2 (CX engine) with lots of extra goodies: 112Meg RAM, 2G SCSI hard drive, *serial port*, Ethernut... and the thing just started going to Hades in a handbasket. It's always been a little flaky with paper handling, but otherwise has been ultra-reliable if you knew it's paper quirks. Now it's durned near impossible to deal with... but that's not the *big* problem. The nearly new black toner cart (less than 1000 sheets of it's 10000 sheet life) is now 'low', the nearly new magenta toner cart ( less than 500 sheets) is *out*, and I had to hack up a cyan cart with the magenta 'code insert thingy' to fool it into printing again (if any toner goes 'emtpy' the printer refuses to print) and the nearly new OPC belt ( less than 2000 of a 30000+ page lifespan) has developed several bad spots. All this seemed to happen within 100 pages or so. :-O Is the printer worth saving, or should I just drop it off my deck (10 foot drop - would be quite satisfying to see, after I strip the HD and memory out of it...)? Or does anyone want it for parts for cost of shipping? (Warning: it's a 110+ pound beastie; it would *not* be cheap to ship.) If it's not worth saving, anyone have experience with a good color laser printer? Preferably < $1000, and I want *bitchin* paper handling (read: no paper jams). Please don't say HP. ;-) The best I've found during my research so far is the Ricoh Aficio CL2000N - about $560 street price, and has oodles of options available (most of which I don't need), affordable consumables, and supposedly really good paper handling, according to the reviews I've found. Oh, and about 1/2 the weight of my current printer. Sorry for the offtopicness, but I don't know where else to turn, and I'm looking for advice from people I trust. ;-) Thanks, Roger "Merch" Merchberger -- Roger "Merch" Merchberger -- SysAdmin, Iceberg Computers zmerch at 30below.com Hi!

And the Technical Reference manual doesn't give any info on the errors at all. I susepct that what we need is the service manual, which is one of the few HP150 manuals I don't have (I've always managed with the schematics in the techref...) My first thought is that after 20 years, the battery is almost certainly flat. On the original HP150, this is, IIRC, a user-replacable battery in a plastic holder at the back. I think it's a 4.5V alkaline battery, PX21 or similar. I have no idea where you'd find one, but I do know that battery is also used in some Praktica SLR cameras, and I think it's still available somewhere. On the 150-II, the battery is a pair of soldered-in lithium cells on the PSU/sweep bnard. A right pain to get to, I can tell you... However, I doubt that a flat battery would give a power-on error. I would think you had some component failure, but I don't know what :-( -tony From ard at p850ug1.demon.co.uk Wed Sep 14 17:48:17 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Wed, 14 Sep 2005 23:48:17 +0100 (BST) Subject: Homebrew Circuit Boards: Methods?

Most photoresists can be 'soldered through' so it's not necessary to strip them. On the other hand, boards look a lot better if you do strip... The method I've always used is to etch the board as usual, wash it, then give it another (longer-than-normal) UV exposure with no artwork -- thus 'fogging' the remaining resist. Then pop it back in the developer and it will all strip off nicely. Remember on most photoresist boards, the bits that are exposed to UV are the bits you want to etch away (the artwork is black for the traces, etc), so the resist that's been exposed is the stuff that comes off. > > So, when using a photoresist system, one needs developer, etchant and > stripper.

It's actally not _that_ strong. Strong enough to feel 'soapy' (it hydrolyses the fats in your fingers), but not strong enough to cause an alkali burn in my experience. -tony From ard at p850ug1.demon.co.uk Wed Sep 14 18:01:09 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Thu, 15 Sep 2005 00:01:09 +0100 (BST) Subject: IBM PC hacking In-Reply-To: <432772C0.4C7A923C@msm.umr.edu> from "jim stephens" at Sep 13, 5 05:45:53 pm Message-ID: > > > > Tony Duell wrote: > > > > I remember a little shop here in Santa Ana which had the first clone of > > > the IBM PC.

IIRC, early PCs used 16K DRAMs (1 row soldered, sockets for 3 more, so 16K .. 64K on the mainboard) Later PCs used 64K DRAMs, so 64K .. 256K on the mainboard. PC/XTs also used 64K DRAMs, and from what I've seen all 4 rows were socketed. There's a well-knwon modification, I am sure everyone here knows it, to put 2 rows of 256K and 2 rows of 64K on the PC/XT mainboard for the full 640K. This was later sort-of supported by IBM, my TechRef has an entry for the 256K to 640K system board. Early PC/AT machines used those special IBM piggyback 128K 'chips'. Up to 512K on the mainboard, you could flip a jumper if you only wanted 256K. Later PC/AT boards used 256K DRAMs, again 512K on the mainboard. The jumper is still present, flipping it wastes half of each IC (you still have to have all 18 chips fitted, it's a 16 bit data bus + parity on each byte). I _think_ the PC/XT-286 had 4 off 64K*4 and 2 off 64K * 1 DRAMs on the mainboard for 128K RAM and then SIMM sockets for 2 256K * 9 30 pin SIMMs. > > > > > > The PC used either EProms, (16K I think) and the Roms that were > > > shipped with the BIOS were registered.

When I built by first microcontroller system (around this time), I had to build my ownEPROM programmer and emulator. 3 wire-wrapped boards of TTL, distretes, a UART, etc. Plugged into an RS232 port. I couldn't, of course, use a microprocessor in the programmer, since there was the obvious bootstrap problem of how would I program the firmware for that? If you could dismantle the PC far enough to pull the ROMs to attempt to read them out in your programmer, then surely you could have added a homebrew serial card or similar. A real kludge would have been to use a couple of printer port cards (which would give you 24 output lines) and a little external circuitry to program an EPROM. These EPROMs were not hard to program 'by hand'. -tony From ard at p850ug1.demon.co.uk Wed Sep 14 18:03:30 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Thu, 15 Sep 2005 00:03:30 +0100 (BST) Subject: IBM PC hacking In-Reply-To: <20050913174342.Y3526@shell.lmi.net> from "Fred Cisin" at Sep 13, 5 05:46:51 pm Message-ID: > Later, they switched to one row of 64K DRAMs soldered in, with sockets for > another three rows.

I can't rememebr if the PC 64K to 256K board has the socket for the extra address mux chip, etc, but I think it doesn't. All IBM PC/XT boards that I've seen can be modified to take 2 rows of 256K chips. And on all the boards I've seen, all 4 rows of RAM are socketed, so it's easy to replace rows 0 and 1 with said 256K chips.

I did not own the programmer, so transfering it via RS232 was not that useful. I could run a program and jam it into a mini that I had (remember no nifty c or basic to process the data on the PC to prep it for even Data I./O format) The Data I/O's we had didn't have published or supported RS232 at the time. This was a nasty and expensive option that was driven from mini's or mainframes and most places had the programmer, with nothing hooked to them. Everyone operated with a master "library" of parts stuck in conductive foam, taped to a description of what was on the part, revisions, p/n's when released and all that crap. The fellows I worked with, who were the hardware enlightend made their own programmer with an old disk controller (with 6802) providing the intelligence and memory to support the programming. As the system did not have the proper programming voltage, there was a small HP lab supply fixed to the programming voltage. It could have been used to move the data to 2732's I guess, but I didn't have a way to get data into that system, as it again relied on reading a source part, and programming a blank.

I have been thinking about this question the last couple of days, and I just want to share a slightly different point of view. I teach Computer Science at a University, and being a pack rat of long standing, convinced our then chairman to let me start a "computer museum" so I could clean out my garage, closets, attic, study, etc. In this environment there is merit in older machines, even if they don't run. One of my favorite items, and one that gets the attention of the students, is a voice coil magnet out of an unknown drive. It weighs about 60 pounds, IIRC. (http://www.cse.uta.edu/TheMuseum at CSE/Whazat.html) I tell them that it was in a drive about the size of a washing machine and that held no more than 100 MB & probably much less. Then I contrast that with a 2.5 inch drive that holds perhaps 10s of GBs and weighs only a few ounces, certainly runs faster and costs less than whatever drive the magnet came out of - heck, probably less than the magnet! Similarly I have a magnetic core plane that gives new meaning to the terms "core dump" and "non-volatile memory" for these students and a tube circuit out of a IBM 709 (or 704 - not sure which) which I show with a copy of an IBM adv. that talks about such tube circuits and the machines that incorporated them. If I had a 709 here there is no way I could run it for even 10 minutes. No power (don't even know what kind), no A.C., no raised floor, ... . Does that mean that it is unreasonable to want to have such a machine here? I would love it. I might only be able to display a part of it at a time, but it would be very educational to compare it to cell phones which certainly have more power, etc. So for me, bigger is better. The more stuff I have, the more I can help give perspective to the visitors who have no comprehension of what it means to say that disk drive technology has improved something like 6 orders of magnitude since they were introduced. I am collecting lots of stuff. I don't have time to turn them all on and mess around with them (though I would love to.) I think it is important to archive this stuff before it goes away and work on finding means to insure the continuance of the collection. Gil A. G.

Some engineers at Honda took the S600/S800 (dual overhad cam 500cc/800cc) design, and built a few with a 359cc engine, and rear bobbed to fit the legal requirements, thus creating the hottest "360" ever made. The Japanese guvmint promptly changed the rules to prevent that sort of abuse. The T360 would also make a good computer collector's vehicle. http://www.hondasportsregistry.com/brochures/brochs360t360s500.php http://world.honda.com/history/challenge/1962autoproduction/ From spectre at floodgap.com Wed Sep 14 22:51:34 2005 From: spectre at floodgap.com (Cameron Kaiser) Date: Wed, 14 Sep 2005 20:51:34 -0700 (PDT) Subject: eBay In-Reply-To: from Vintage Computer Festival at "Sep 14, 5 07:16:20 pm" Message-ID: <200509150351.UAA16500@floodgap.com> > > I truely pity anyone who is only interested in having the biggest > > collection and has no other real interest in the machines themselves.

At one time I had ten of them in the back yard here for a couple of months while I worked on them-huge washing machine type drives. That voice coil assy on you web page is something I well remember - probably used in may different drives but they are identical to the ones in the CDC (Control Data Corp) drives I 'rendered down' about 20 years ago. I still have two or three of the centre pole pieces (great door stops) and a few of the permanent magnet pieces (they were in three 120 degree segments I think) from the VC drives. Had an identical VC to the one in the picture as well till quite recently. There's still some docs round here somewhere for those drives. They were ex an ICL system-can't recall the model.

The recipe I remember is 7 grams NaOH in 1 litre of water. One can use normal rubber gloves (as used for cleaning puroses) if one is afraid to touch the developer.

Many alkaline solutions will burn skin at lower concentrations than acids. Even tiny quantities of alkali can cause serious eye damage. Peace...

Recent imports aren't so bad. For a while, small manufacturers didn't have a clue on how to handle the requirements and hacked up quick and dirty and ugly solutions. You can change any car within the rules that applied for its model year. For older cars that means you can make it much better than the import model, but perhaps not exactly like the European model. An example of a company that gets this right is Morgan. Their US models look just like the European ones -- really nice. paul From bill at timeguy.com Thu Sep 15 10:11:08 2005 From: bill at timeguy.com (Bill Richman) Date: Thu, 15 Sep 2005 10:11:08 -0500 Subject: Various Macs Available In-Reply-To: <200509150254.j8F2rgm1013286@dewey.classiccmp.org> References: <200509150254.j8F2rgm1013286@dewey.classiccmp.org> Message-ID: <20050915151108.GB27647@outpost.timeguy.com> I've got several old Macs; Color Classic, plain Mac Classics, some older Apple monitors, and a couple of LaserWriters that are going to hit the recycling center unless someone wants them.

Today I tried the modem board (HP 82915) in my Integral. The machines powers up OK, and the load_modem command finds it and loads the driver. But any attempt to access /dev/modem00 (using stty, kermit (on the super-utilities disk), etc) hangs the machine. I decieded to do some investigating. Probing points on the I/O cards is difficult with the machine assembled, and I don't have an extender board. There is, however, a way to get good access to the boards, but it involves a little work. Remove the rear cover and rear screening plate over the logic assembly. Unplug the 2 cables from the back of the floppy drive, remove the 3 screws and the drive itself. Remove the eject button and spring before you lose them. Undo the screws holding the logic chassis in place. Unplug the power cables, HPIB cable, expansion backplane cable and HP-HIL cable from the logic boards,Leave the other (printer) cables connected, move the logic chssis towards the top of the machine. Remove the HP-HIL grounding nut (through a hole in the expansion backplane), then the 4 screws holding the PSU/expansion box in place. Take that out Undo all the screws and nuts holding the cover on this unit. Move the cover out of the way Undo the nut on the backplane earthing bracket, remove the 4 screws, the bracket, and the backplane. Reassmble and refit the PSU box (you don't need all the screws), plug the cables back into the logic assembly (you can leave off the HPIB cable if you're not using any HPIB peripherals at the time), plug in the expansion backplane cable with the backplane hanging behind th PSU box. Fit a couple of the logic chassis screws. Refit the floppy drive, hold it in place with at least 1 of the top screws. Recoonect its cables. The machine will run like that, and you can plug the expansion board into the backplane and probe pins on it. Now, to understand the next bit, you need to know a little about the design of the modem. The address decoder is simple. It responds to the slot-specific chip select line from a decoder on the CPU board, and further decodes lines A6 and A5. It provides 4 chip-select signals A6, A5 = 00 : Command/ID register. Bits 4-7 (only) used on write, to select interrupt line, force and enable interrupts. On read, bits 4-7 are much the same, bits 0-3 are a fixed ID value that identifies this as a modem. A6, A5 = 01 : Select 8250 serial chip. Address lines A1-A3 select the 8 registers in this chip in the usual way A6, A5 = 10 or 11. One selects the modem Tx chip (16 internal registers selected by A1-A4), the other selects the modem Rx chip (also 16 registers, selected by A1-A4). Anyway, after probing pins on the address decoder circuit and repeateded powering down/up the machine and running load_modem, I discovered that the only 'register' that this command accesses is to read the ID register, presumably to find a modem board. It does not attempt to initialise the serial chip or the modem ICs. I have the customer diagnostic disk. This also finds a modem, and I can run the diagnostics on it. It pases. It also seems to write things to various registers on the modem board (in particular, at the end of the test, the 8250 is left set to 1200 baud, the baud_out pin (wired to the Rclk input as usual) is running at 19200Hx). And it energises the line relay a couple of times. Any thoughts? Do I have an obscure hardware problem or just not the right software? -tony From ard at p850ug1.demon.co.uk Thu Sep 15 14:22:07 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Thu, 15 Sep 2005 20:22:07 +0100 (BST) Subject: IBM PC hacking In-Reply-To: <4328BE12.26042D3A@msm.umr.edu> from "jim stephens" at Sep 14, 5 05:19:30 pm Message-ID: > > A real kludge would have been to use a couple of printer port cards > > (which would give you 24 output lines) and a little external circuitry to > > program an EPROM.

Steven, You left out the URL, but from the description, I'd say you were writing about Sierra Proto Express. I've used them before with good results--both 4-layer protos and a batch of 200 boards from their regular service. However, the catch with the proto services is that they're all limited to .062" thick board and for this particular application, I need .050" board. That simple change in board thickness changes much of how one would normally get some simple boards made. I've even emailed several proto services to ask if they could do .050 as a proto, but they won't, which is understandable.

IIRC, that board was one of many multi multi-function cards. Everything including the kitchen sink. The original PC had 5 slots, as did some clones (Tandy 1000 comes to mind). So it was advantageous to have every bloody thing you needed on one card if possible. Again, iirc, the zukerboard or whatever was sort of cheapo. Don't quote me. > I know of at least Zucker, Tecmar (marty tech, I > don't remember marty's > last name, but he was some sort of PHD ohio type, I > think). There were a bunch, even into the (late) EGA days (you could get 800 x 600 and maybe better with some cards, as long as you had a multisync monitor). Don't forget the overseas types which didn't carry any particular vendor's name. > I remember a little shop here in Santa Ana which had > the first clone of > the IBM PC.

Sigma 400, STB, Tecmar, Taxan, and others made them. Then there's IBM's PGA card. I have a similar card made by Vermont Microsystems. Takes up 2 slots, and has an onboard 80186. Works the last time I tried it, but probably impossible to find drivers or docs for. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

It doesn't look like it is a standard product so good luck trying to find a source for small quantities. If you only need one or two you can probably get them for free as samples directly from EDAC. I got a couple of free samples from them, 305-048-500-202 which works as an HP-2100 or HP-1000 I/O card connector for 48-contact cards, and 305-086-500-202 which for EXORbus cards. I haven't found a source where I can buy these connectors in small quantities.

It's heavy and big though. The typical configuration was 16K to 32K of memory (core or MOS), one RX8E, one dual RX01 or RX02, a KK8A CPU card, and the typical KM8AA and DKC8AA hex-height multi I/O cards. Some DS-310s might have a printer interface of one sort or another for anything from an LA-180 up to some sort of daisy-wheel printer. Another semi-common option was the KL8A quad-serial interface. I think there was support under WPS-8 to allow multiple WPS users on multiple VT52s, but I haven't tried that myself. http://www.faqs.org/faqs/dec-faq/pdp8-models/ http://www.cs.uiowa.edu/~jones/pdp8/hard8e/modules.html It's a great platform for running OS/8 on... quad or hex cards, supports 128K (w/KT8A and hex MOS memory modules), but not the right packaging if you want to use the programmer's panel (the CPU sits in front of the user's feet, facing the wall), unless you have long cables and mount the panel over or under the floppies beside the user. I have one RX02 and one RL01 in my desk, leaving no room for a front panel. -ethan From lbickley at bickleywest.com Fri Sep 16 15:09:34 2005 From: lbickley at bickleywest.com (Lbickley) Date: Fri, 16 Sep 2005 14:09:34 -0600 Subject: TSX Plus...

They are relabelled Digital Computer Controls D-112, clones of the PDP8/I. Bruce Ray has a few pictures up on his website: http://www.simulogics.com/nostalgia/DCC/dcc.htm When I examined them, I didn't see any memory, indeed, my suspicion was that only the proprietary CMC boards remained. --Bill From jwest at classiccmp.org Fri Sep 16 17:39:40 2005 From: jwest at classiccmp.org (Jay West) Date: Fri, 16 Sep 2005 17:39:40 -0500 Subject: RESOLVED Re: Heathkit ET-3400 red filter material?

I decided to go ahead and dig in to this, even though I probably didn't have the requisite information in hand (headers from Gordon) to trace this down. I have determined that Gordon is posting from gordonjcp at gjcp.net, when in fact he is not subscribed from that address. He is subscribed from gordon at gjcp.net So, what is happening here is his posts are being held for moderation every single time...

Monitor circuitry is, not suprisingly, similar to TV circuitry, in fact the older (fixed-scan rate) monitors were in some cases almost indentical. I would start by getting some good books on TV servicing. Unfortunately I can't recomend any of thsoe either -- I started learning about TVs when they were full of valves, and all my introductory books date from that time. I have not found a good book which covers multi-sync monitors at all. Some service manuals are available (either officially or not), but often the theory-of-operation is conspicuous by its absence. You get a schematic and setting-up info and little more. > recommendation for something general would be > appreciated, whether a past or present publication. > Purpose: the investigate the possibility of modifying > a recent multisync to sync down to TV frequencies.

Personally I think it would be easier to find an old TV-rate monitor and repair it, even if you have to wind replacement transformers yourself. But anyway... I am sure you know that the horizontal output stage also supplies most of the high voltages for the CRT. It is not at all obvious to me that you will be able to drop the scan rate to TV rates and maintain all the voltages at their correct value, and maintain the image width. -tony From ard at p850ug1.demon.co.uk Fri Sep 16 18:17:23 2005 From: ard at p850ug1.demon.co.uk (Tony Duell) Date: Sat, 17 Sep 2005 00:17:23 +0100 (BST) Subject: eBay In-Reply-To: from "Vintage Computer Festival" at Sep 15, 5 06:39:58 pm Message-ID: > > Because this is classiccmp, so anything else would be off-topic. > > Even clocks, cameras, and radios?

Eeek!... I remeber that book when it was current. As you've probably gathered, the 'ladybird books' were aimed at children, and I think I had all the 'How It Works' series. [The one I particularly _disliked_ was 'How It Works -- The Telephone'. I could not understand that book. I couldn't understand it when I re-read it several years later. I finally understood it when I bought a copy of 'Telephony' about 10 years ago. 'Telephony' is a book that was used by telephone engineers in the UK, and contains complete schematics for telephone exchanges, etc). I realised why I couldn't understand the simpler books, far too much had been left out, so what remained made no sense. There is a danger in oversimplifying things. Another Ladybird book was called 'Making a Transistor Radio'. It covered building a crystal sed, adding a single transistor audio amplifier, then a second stage and a speaker, and finally replacing the detector with a regenerative stage. The final set was a 3-transistor AM receiver using a couple of OC71s and an OC45. I think just about every UK electronics enthusiast built that at one time or another. -tony From leeedavison at yahoo.co.uk Fri Sep 16 19:31:42 2005 From: leeedavison at yahoo.co.uk (lee davison) Date: Sat, 17 Sep 2005 01:31:42 +0100 (BST) Subject: Computer Machinery Corporation?

Modern multisync CRT monitors contain lots of circuitry to manage the various linearity and distortion problem imposed by the need to vary sweep frequencies. The horizontal sweep components, in particular, won't let you get much below 32 Khz or so. I suppose one could use a TV-freqency video "frame grabber" on a PC to acquire then display on a modern monitor, but that seems to be the long way around the job. Far better to find an inexpensive broadcast receiver and hack into the video and sync circuitry as needed. My first 64-column monitor (hooked to a modified SWTP TV Typewriter) was an old tube-type Zenith monochrome portable TV (with an isolation transformer on the mains supply, since this was a "hot chassis" model. Worked just fine until I latched onto a Beehive Super Bee terminal. Or cruise the junk shops for old monitors--there should still be a few wandering around that have 15-18 KHz horizontal sweeps. I think I even have an old Mitsubishi Diamond Scan monitor that will sync between TV and EGA frequencies. I use it with an RGB demodulator and an East German VCR to view PAL VHS tapes that friends from Europe send me.

Eeek! ... Personally I think it would be easier to find an old TV-rate monitor and repair it, even if you have to wind replacement transformers yourself. But anyway..." This may not be all that hard. In fact, the early NEC "multisync" monitors DID this, as they came stock from the factory. CGA, MCGA, EGA and VGA. They even came with 9-pin to 15-pin adapters to deal with the two different connectors in use. I'm not sure that current monitors still do it in their "stock" configuration, BUT I WOULD NOT RULE OUT THE POSSIBILITY THAT SOME MIGHT.

Additionally the hardware was both bulky (switches) and even in volume costly. SWTP by going with a rom monitor made a simpler machine with fewer parts. The cost to produce was lower and they also gained in that when roms, and other digital parts became cheaper they could pass the saving or reap the profit where switches and leds didn't drop in cost nearly as fast. There were a bunch of subtle evolutionary ideas in the SWTP systems that were widely adopted such as standard IO types and addresses. The effect being the user was less likely to have to configure the hardware and more likely to find new software [especially for similar but not identical systems] that were compatable. All of this was an outgrowth of how Motorola supported the 6800 vs Intel vision. The offset was with a front pannel troubleshooting a sick system was often easier but was an expensive artifact when not needed. Even though 6800 and 6502 based systems where not my forte' I studied them early on to see why they were so pervasive and largely successful. I feel that their break with the front pannel concept was a jump ahead for them. As a result the next system (ca1977) I'd gone with was a NS* horizon to get away from the switches followed closely with Netronics Explorer8085 for the resident rom monitor for S100 diagnostic abilities.

That is just to copy the files over to MS-DOS disks, where they can then exist in folders on a modern hard drive or be put on CDs or DVDs. I can really see no advantage to a strict "image", as long as one has the files. The issue that this leaves out is the system tracks, but that is easily dealt with: Runs "SYSGEN", exit, and then do a "SAVE 34 SYSTEM.COM" and you have the system tracks as a disk file in a format that is easily restored simply using SYSGEN. This method also has some actual advantages, in terms of being able to actually use the software with a CP/M emulator on a PC. Since I'm not aware of any CP/M programs that did copy protection or any other type of manipulation that would require an exact disk image, I don't really see the drawback of this approach.

The Tomy Tutor is an American home computer released ca. 1983 with strong hardware commonalities to the TI 99/4A. The Little Orphan focuses on the American Tomy Tutor, along with its Japanese cousins (the Pyuuta series), and offers a catalogue of hardware and software, programming information, technical documentation and links to related sites. Here's what's new or changed: - Pyuuta Jr. entry, featuring a complete description of this Japanese console version -- yes, I finally got one! Includes pictures, scans from the manual, and screen grabs of its surprisingly robust and user-friendly interface (for 1983, that is). - Stub entry for the Grandstand Tutors, the vanishingly rare UK variant. - New emulation section. This includes a special section on using the MESS Tomy Tutor driver (focused more towards the Mac, since I'm a Mac user, but with help for Windows users as well) and needed firmware and dumps, intended only for those with a legal right to the hardware, of course. Also includes TutorEm, the first true emulator (Windows-only), and incorporates Tutti as a museum piece (though people who do not own a Tomy Tutor can still use it to legally simulate the Tutor without ROMs). Alas, with this site release, I have chosen to officially freeze Tutti, the first Tomy Tutor simulator of any kind, at 0.3. It will still be left for download indefinitely because of its unique legal status, however. - Updated Incomplete Catalogue. Improved screenshots for many games, new shots for many more (including the believed-unreleased Gajigoji and Jack In The Box), and additional stub entries for hardware to come later. All of the American clone games have also been matched up to the Japanese originals. Also included links for the MSX and CoCo ports! - Additional Pyuuta screen shots. - Updated my personal trade list and the General and Pyuuta pages' histories, and made various custodial changes.

Excellent point! Since the CP/M world was so fragmented among hardware vendors, manufacturers wanting to protect their software simply tied it to a specific host hardware (e.g., SuperCalc 2 special trade-up edition for the Osborne). There may possibly be an exception for one of the very common platforms, such as TRS-80, but I'm not aware of one.

I was reading in a few hundred tapes at the time onto 386 and 486 systems. The trick was getting the harddrive subsystem to handle writes at that speed. Just getting multiple gigabytes of storage on a PC was a major challenge at the time. When they all finished loading (days later) we backed them up to Exebyte 8500 8mm drives in a matter of hours. 1 5G tape held the (compressed) data from over 75 9-track tapes. -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!

Now, this is not your run of mill 20" TV. These RCA 20" models of any models I do service of all kinds of RCA chassis except there is at least 2 models I heard about with particular CTC168 chassis which is only for 20". I've not seen CTC168 in my whole 3 years of TV service, even I have done so many TVs and projectors with CTC169 chassis and all different kinds of newer and older ones with types of RCA chassis. Except this one! The features is LOADED for a 20" TV imagine loaded Chevy landyatcht of luxurious stuff in an Omni (Rabbit look-like). Two RF inputs, One RF out, Two video inputs and one Video output, S-video, stereo ampified outputs along with internal stereo for set of 4 speakers total driven by either 5W to 10W ampifiers (most of others usually muddy .5W to passable 1W stereo, 4 more unampified audio outputs. and I think one or two sets of audio inputs. This is a TV basically a features of a larger cousins of CTC169 for direct-view CRTs and 3 CRT projectors. What a mouthful for a old rare model 20" TV. The extreme rarity there is a reason; back then was high price for 20", appox $500 so this particular models. Compared to 1990/1991 19"/20" of any makes/models typically run for 200 for plain janes sh*t to high 250 for decent models with few features, except Sony that had some features with outragous 300-500 tag!). I talked to Jack, our shop boss and did say had one CTC168 in for repair years ago and that was only one. For me, this tv is like a find of a day. :) Akin to finding a PDP 8 on the ground with trash beside a rowhouse street very near downtown. :) Back to your "exciting" regular programming, thanks and I still enjoy your "text programmings" chatter. Back on topic: Won L40SX (PS/2 386SX 20 laptop) on ebay, fairly complete: power brick (Yes, a BRICK), quick charger brick, external keypad and few booklets. Replaced LCD lamp successfully, old one failed to light by extreme age. Took a IBM 4MB SIMM modified with correct sensing pins and chewed off a SIMM socket's nub to get 8MB instead of 6MB installed. L40SX takes deep middle notch 72 pin SIMMs. Except most decent parity SIMMs can be used with proper modifcations except 8MB had to be single sided and is max L40SX can take for max of 18MB. To do list: rebuild battery pack and replace two internal batteries for cmos and standby power.

S&H thought they had their copies secure, but they in fact lost the source code, correct? My concern is that there be an off-site backup for this stuff, in case what happens to S&H happens to you. Just sending copies out to hobbyists may not ensure the stuff survives, as sending it out to paying customers obviously didn't (or almost anyways, given the interest here). Common practice on the net is arranging for mirrors (which don't have to be public). But as long as the stuff is stored in multiple locations that should probably suffice.

The one main drawback is that this is not an accurate or appropriate way to create an image for historical preservation.

BidPay is Western Union's internet payment service. I had a similar problem a long time ago in a similar situation. BidPay refused to allow a person-to-person payment. I got a customer service manager on the phone and ripped him a new asshole.

I built up two versions of an unbuffered controller; the first using 74LS00 "glue" chips on an ISA proto board and the second, a PCI card using 82C55AC's (10 MHz 8255's); one for control and the other for data. The ISA board could not keep up using DMA or programmed I/O with the Fujitsu, which was firing out data a bit faster than 1 usec. per byte. The PCI board could just barely keep up (this was using 32-bit code; I suspect that the board has a few too many wait states buried in the FPGA used for interfacing). The Fuji drive is of traditional reel-to-reel open construction, and while it has a high-speed mode, I don't think it could be called a "streamer" in the sense of the Cipher. It's built like a battleship and weighs probably close to 150 lbs. If I can't make heads or tails of the Computer Logics board or obtain another board with similar functionality, I'll probably move next to a dedicated microcontroller (I've got a RabbitCore 2000 kit around here somewhere) and a USB 2.0 interface to the PC.

Amazingly, then, the kermit supplied by HP for the Integral does not support the modem. Hmmm... One to watch for if you're trying to get one of these modems to behave. Alsa, from what I can see the Datacomm program is user friendly (in other words, hacker hostile). It only lets me set 300 or 1200 baud (why not 110? A 300 baud modem will work at lower baud rates). It only uses the modem in 'originate' mode. It does pulse dialling, not DTMF (why???) But it seems to work. My only problem now is getting something for it to talk to. I have no intention of using it on anything other than a bit of cable on my bench, so approval is not a problem.

This is the 16 bit parallel I/O card for the DIO bus, as is used on the 9836, etc It came with a user manual. This was a lot more use than I expected it to be as it includes a schematic. It's a fairly thin manual, but full of information. One interesting diagram at the back shows the correspondence betweene the DIP switches on this card and the links in the 98032 I/O module for the 9825... Anyway, it describes 4 'options' for this card. Each one was a particular cable -- one was the 50 pin Blue Ribbon plug to fit the card and bare wires on the other end. The other 3 were wired to connectors to fit the 9885 disk drive (9" floppy), a Multiprogrammer (I forget the number, but the one that didn't have an HPIB interface) and finally one for the 9866 printer. The manual does give the switch settings to use the board with each of these devices, but no wirelists of the cables. And amazigly I have all 3 of the listed peripherals. So my question is obvious. Does anyone have any of these cables and could 'buzz out' the wiring? -tony From curt at atarimuseum.com Sun Sep 18 17:36:46 2005 From: curt at atarimuseum.com (Curt @ Atari Museum) Date: Sun, 18 Sep 2005 18:36:46 -0400 Subject: Don't use "BidPay"!!!!

If this is like my VAX 4000/500 systems: QBUS "MSCP" (disk capable) SCSI controllers are hard to find and hundreds of dollars. The route I'm trying to go is I picked up some HSD30 controllers on Ebay, for $35-$45, which I can then supposedly connect regular SCSI disks to, though I haven't gotten things set up and working yet this way.

For this reason I >recommened against what you describe. Somehow I missed the beginning of this thread (had a few mail probs lately), so please forgive if I am wandering too far away from the original topic, but I gather we are trying to figure out how to best preserve CP/M disks. I to agree that copying the files is not the best solution - even if you do the SYSTEM.COM thing, you still need a working CP/M boot disk to be able to make a boot disk (chicken and egg type of deal) - Having restored a number of systems for which I did NOT have an original boot disk, I can tell you that this can be an issue. I've used ImageDisk to backup and restore quite a few CP/M disks by now, and it works well, deals with system tracks just fine, and allows you to make a bootable disk from "starting point zero". It does have two limitations: - For 8" systems, you will have to attach an 8" drive to your PC ... I've put up a page on my web site which describes this in a bit of detail, including an adapter thats very easy to make to convert the 8" interface to plug into a standard 5.25" cable. - The disk format must be one that is compatible with the PC's 765 controller The only work-around for this is to use CPT. For cases where the disk format is not compatible with the PC (hard or non-IBM format sectors), I have created CPT (CP/m Transfer) which is also available on my site - CPT transfers disk images to and from the actual target system over the serial port, and can work with ANY format disk (because it uses the targets disks and controller). CPT has a different set of limitations: - The target system must have a serial port (it doesn't have to be the console). - You need to provide a very small binary serial port driver for the CPT resident client. Even if you don't know how to talk to it, looking at the device number of the UART, and a few minutes tracing vectors and disassembling with DDT will usually give you the info you need. - CPT can't always handle system tracks - CP/M does not provide a standard way to read/write the system tracks, and on some systems they are different from the user tracks and incompatible with the system floppy driver. CPT allows you to skip them, and you could use SYSGEN/SAVE to place a copy of them in the user area. - CPT requires you to have a working target system backup and recreate the disks. It *SHOULD* be possible to save a memory image of loaded CP/M and FORMAT which can be loaded into a bare system to create a formatted disk. I have not had to do this with CP/M yet, but I have done it with Cromemco RDOS which is similar. Note that you still need a means of getting the memory image into memory and launching it at the right address (for Cromemco you can use RDOS) - I have a very tiny (<500 bytes) 8080 monitor which would work for this purpose. With CP/M you would need to have a second memory image with SYSGEN, and system tracks preloaded in memory, and possibly a third with the CPT client preloaded - but these should be possible, at which point you could use CPT to transfer over full disk images. I've been toying with the idea of writing a program to allow you to list the directory, and import/export files to/from a CP/M ImageDisk image (or perhaps just a straight binary disk image which IMDU can create)... This would allow the files to be used under a CP/M simulator that uses the DOS file system fairly easily ... too busy to even start right now, but perhaps sometime this winter.

How in HELL do you get through a week?! Where does it all go? Honestly, I'm not sure. I'm tempted to say that there just isn't really any classic stuff left in the UK that hasn't found its way into the hands of enthusiasts already. Having said that, a lot of the big companies are still hanging on to 80's-era equipment (VAXen and the like). From the point of view of someone involved with a museum, we still get a trickle of big stuff - maybe around 80% DEC, 10% HP, and 10% other. But I do suspect that most of it's gone to the crusher long ago, or is locked away in company basements "just in case" (I suspect in the latter case it'll now stay there due to the disposal requirements that Simon mentioned) As I've said before on the list, the computer recycler local to my home back in England does get larger classic stuff from time to time - he parts them out, with the boards going to someone who rips them apart for the gold, and the chassis' all go to a metal recycler just down the road from him where they're immediately crunched. I suspect the same is true for the other recyclers in the country - I suppose there just isn't the space for computer graveyards like in the US. The curious thing is that 8 bit home micros seem to have all but vanished too - perhaps that's because there's no obvious place to get rid of them to, and what's left is still tucked away in cupboards of the owners (who perhaps have no clue what the machines in question are). Hence the reason I suggested freecycle lists, as they're becoming quite popular in the UK and it doesn't hurt to join and mention that you're interested in any such hardware. FWIW, car scrapyards are the same in the UK these days - gone are the days of huge yards with all sorts of gems tucked away in the corners. They're much smaller these days with only a few pretty modern vehicles, and places that part out scrap cars (and then sell the bits at much higher prices) seem to now be the norm.

You best bet on this is to modify the input signal rather than the monitor itself. The analog circuitry in modern monitors isn't all that hackable. Devices that do signal conversion are called scan converters/line doublers/flicker fixers. You can find video-VGA conversion boxes just about anywhere. Also check for CGA-VGA converter boards (usually advertised as being for arcade video games). If you really want to do it youself, you can probably find a schematic online that will do the job. It takes some logic, 3 or 4 high speed ADCs (assuming you want color), some memory, and 3-DACs. There are some chips that will do the whole job, but I don't know too much about their capabilities and adaptable they are.

They will investigate in cases of large dollar losses. The only good part of that is that it's total loss, not what you personally may have lost - big time scammers have a better chance of crossing that line, if everyone who got scammed reports it. The net is rife with stories of successful and unsuccessful pursuits of scammers. YMMV. OTOH, I won't use BidPay either. I don't like Western Union, and I don't like their fee structures (of course... pretty much any technique has its problems). -ethan From dwight.elvey at amd.com Mon Sep 19 18:45:11 2005 From: dwight.elvey at amd.com (Dwight K.

They like to know about counterfeit MO's. One rule is to never except a money order for more than the sale value. There is no reason the buyer can't make it for the exact amount. Also, if a seller, only except postal money orders. It is not that it offers any more protection it is just that the PO gets more excited if there is a counterfeit postal money order. I don't expect that the PO would correctly handle a refund, I just expect that the seller would think twice about a federal crime as compared to a state law. Postal money orders sent through the mail are federal issues. The only other thing I don't like about postal money orders is that they are real slow about checking to see if the money order has been cashed. You'd think with the current day computers, it should be an on line operation, taking seconds.

The PostMaster General won't even look at anything less than $10,000 USD, at least in domestic cases. My boss suffered ID theft a couple of years ago, and the that hijacked his cards literally ran about $9950 on each account. She did so by submitting change-of-address affidavits by mail, which made it mail fraud, but since no single card was defrauded by more than $10k, the PO never even looked at it, even though my boss put proof in their hands and even though they were aware that the same individual had gotten away with 3 other instances, doing the same thing.

Oh I'm quite sure they are just BURROUGHS reels, with crap old data on them. THere was a hand-scrawled label, some sort of data saves or something.

Any sort of machine-to-machine setup assumes that you have a boot diskette that enables the target system to (1) run CP/M (2) has comms hardware that you can understand and patch for and (3) has diskette hardware that you know about--or that the format on a diskette remains consistent enough that it can be accessed through CBIOS calls--and (4) has a comms port. This can turn into quite a chicken-and-egg situation. Out of the several thousand diskettes in my collection, quite a few are not CP/M; a few more that run CP/M provide no way to create an initialized system diskette from a blank; and a few that provide no access other than direct hardware manipulation to the system tracks. The next time you acquire a Future Data or Durango F-85 system, good luck with these! The Future Data is non-CP/M, uses a GCR format for recording and whose hardware is a pretty much a mystery. The Durango uses its own 100 tpi GCR diskettes, does not include a comms port as standard, and was shipped with Durango's own operating system (although I did do a CP/M port for it back in the 70's, it wasn't so simple and the CBIOS was huge). I keep some images around as Catweasel-type raw images and these are pretty good for archival purposes, but there are twists, such as hard-sectored diskettes or strange drives (say Motorola VersaDOS or Victor 9000 systems) that can make resurrecting a physical boot diskette a challenge. Another downside is since Catweasel images are essentially time-domain types, every flux transition requires 8 bits to describe, these run into the megabytes. And you can't simply look at one with hex editor to see what's there. But it's better than nothing. Tim's approach of keeping images around as SSSD A1 type images isn't bad at all, things considered.

Many sellers asking for BidPay are located outside of the US. This means that any fraud would be up to law enforcement in the seller's country. Vigorous prosecution of a foreign claim isn't something that I'd want to roll the dice on. --Chuck From chrism3667 at yahoo.com Mon Sep 19 20:42:40 2005 From: chrism3667 at yahoo.com (Chris M) Date: Mon, 19 Sep 2005 18:42:40 -0700 (PDT) Subject: Scan doubling, was Re: looking for a book on monitor theory In-Reply-To: <432F0CE7.4080506@gjcp.net> Message-ID: <20050920014240.34578.qmail@web61014.mail.yahoo.com> > > I'll echo that I don't think it's practical to do > this.

I'm sure you have a better handle on this then I do, but they're built not to go below ~32khz these days, because there's no reason to. The earlier multisyncs went down to 15.75khz. I wasn't suggesting it wouldn't be a sizeable job. Might not be practical, who knows. It would just be nice to have a way of producing an output from a vintage puter in the absence of anything older, and larger (19"+). > > I suppose one could use a TV-freqency video "frame > grabber" on a PC to acquire then display on a modern > monitor, but that seems to be the long way around > the job. That's actually an interesting suggestion, but I'm not generally looking to grab interlaced stuph at tv frequencies. Still it might be easier to modify something like that then modifying the monitor itself (?). To sync down to cga frequencies would be nice, but generally the puters/cards I'm looking to work with are around the 25khz area. Princeton used to sell an item called a scan doubler. It allowed the use of a 400 line non-interlaced monitor with a cga frequency card, in effect doubling (almost) the horizontal sync rate (I guess the overscan wasn't doubled, so 15.75khz became about 24-25 khz, not 31.5khz). Information of something like that (I can't find one) would be appreciated. There were similar things for the Amiga IIRC, but maybe those were just "flicker fixers", and only took it's interlaced video and changed it into non-interlaced (?). __________________________________ Yahoo!

I used BidPay years ago when PayPal was still X-something or other and only covered the US. As far as I can remember, I paid BidPay and they would send a US$ MO to the recipient. Said recipient would then presumably head off to wherever and cash it (and then hopefully send along my goods). At which point can they end up getting cheated? In particular, since BidPay used to send confirmation emails to all and sundry, how can the seller get bitten?

Aren't there relatively inexpensive scan converters these days? Iv'e used a few, input VGA output TV, nasty-looking chinese-made boxes for $80 or so. Fancy ones do buffering and complex conversions, but shouldn't be needed here. I too have a bias towards home-brew but there's times when forking over cash solves the problem instanter.

If it went out, it was intended only for Pat. But having interrupted you, let me ask a question. I have some documents I am going to be scanning. Mostly they will fall into two categories: 1) Things that are mostly schematics. 2) Things with a large text component that I might want to try to OCR. Questions: a) What resolution should I use for these two things? b) What OCR software do you recommend when I am scanning a book that has to be scanned 1 page at a time. I started with the Brainiacs book from Edmund C. Berkeley and every page is a separate tiff file. Now this book has very little text, so I could just tar them or zip them, but if I had one with lots of text, how can I get all these tiff files back into one document when I OCR it without a bunch of cutting ans pasting?

I use Corel OCR-Trace v8, from 1998, nearly on topic. It really wants to use 300dpi 1 level, and I typically save as 300dpi 8bit for posterity, then downcast to 1bit before the OCR. Scanning at 2400 bpi seems too much like microscopy to be practical . John A.

Gary, I set up space for you on the classiccmp server to put up the cpm archive back on 6/15/05. There's no reason to wait on the new classiccmp.org website design.

BTW, your email address looks familiar. ;) The RLV11 doesn't work on a VAX, because it can only do 18-bit addressing, not 22-bit addressing. The RLV12 works fine on a VAX, as SRM and VMS both identify it, and use it properly. I've made images of quite a few RL02 carts using VMS's BACKUP/PHYSICAL command.

I've got news for you, they will freeze payments even with NO complaints! A friend of mine's brother sold a laptop on E-bay for $800. He recieved payment via PP and shipped the laptop. The buyer confirmed that he recieved it and that he was satisfied with it. Months later E-bay pulled $800 from the seller's account for the transaction with no explaination. The seller checked with the buyer and the buyer was still satisfied with the transaction and said that he hadn't made any complaint to PP.

The last time that I talked to my friend it had been going on for 8 months with no end in sight. A word to the wise; PP is not a bank and is therefore not regulated. They can do anything they want and you have NO recourse. I frequently sell stuff on E-bay and I have a LOT of people that want me to take PP but I absolutely refuse to!!!!

If you are into robots, not just the Hero, someone in California bought out all the RB5X stock from the original company in Denver and will be selling kits next year. He's made a mention on the rb5x Yahoo Group of a target price of $1,400 including charger and speech board. Tying back to earlier list discussions, this is the robot with the INS8073 "TinyBASIC" chip - easy to program form either a serial terminal or PeeCee w/terminal emulator.

I *do* expect them to be better after the eBay take-over. eBay gets it's money exclusively from sellers, and is clearly biased toward sellers. I'd expect that to rub off a bit on their subsidiary, over time. Of course, to the extent that both are near-monopolies, neither will be inclined to do all that well by their customers. (That said, I still think both are providing excellent value.)

IrfanView's "Enhance Colours" tool is very handy for converting greyscale images to B&W. Set the contrast to maximum (127), then tweak the brightness until you get something resembling readable text. Remember the settings, then use them for the rest of the scans. Freely available from (freeware, no source code, Windows only). I used to use ImageMagick when scanning books - I loaded the image into IrfanView to find out where the "shadow" started (on both odd and even pages). Next I used IM to crop them, then convert to B&W (100% contrast, play with the brightness). Finally I used Irfanview to convert the images into G4-compressed TIFFs. I always kept the cropped (and uncropped) 8-bit greyscale images though - just in case the extra quality was required at some point. - open source, runs on basically anything with a C compiler. Another hint: Tumble is very handy for converting TIFFs into PDFs. - only officially works on Linux, but I've had it running on Windows too after compiling it with Mingw32. Hasn't been updated for nearly two years, but still very handy when used in conjunction with Imagemagick.

Depends on the operating system. NetBSD uses only 18 bit DMA addresing for both UniBus and QBus. (NetBSD treats UniBus and QBus (nearly) as the same). Any further addressing is done with the UniBus map / IO-MMU. So with NetBSD you can use a RLV11. I know this as a RLV11 is mounted in my VAX 4000-400, driving a RL02. :-) The problem with the RLV11 is: It is a two card set. It needs two QQ/CD slots and uses some pins on the QBus for test signals, that are used for Q22 signals also. I had to open some traces on the board to make it work in the Q22 VAX. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/ From cclist at sydex.com Wed Sep 21 10:51:59 2005 From: cclist at sydex.com (Chuck Guzis) Date: Wed, 21 Sep 2005 08:51:59 -0700 Subject: CP/M archive to image 8" CP/M floppies In-Reply-To: <200509201205.41380.pat@computer-refuge.org> References: <20050919132605.CZDV10461.orval.sprint.ca@smtp.sprint.ca> <200509191000000466.0A952516@10.0.0.252> <200509201205.41380.pat@computer-refuge.org> Message-ID: <200509210851590914.14A393C0@10.0.0.252> On 9/20/2005, Patrick Finnegan wrote: >If you use Tim Mann's catweasel tools and generate DMK images (are there >any others that run on Linux?), it definately does not store them in >flux-transition format.

Record the raw image and then use it to reconstruct the original if the original starts to fail during subsequent reading. I encounter this quite a bit in old off-brand 5.25' diskettes used in Commodore 15xx drives. You know it's all over when you start to hear that awful head squeal. It usually means that the floppy is toast and that you need to get your head-cleaning kit out. Speaking of Commodores, has anyone found a better drive than the Chinons for the 1571? In particular, the Chinon's seem to have a less-than robust upper head support structure. I've got some old CDC/MPI drives that look like they may be good candidates for modification.

A nice hack would be a cgi script that *mounts* the CP/M image for FTP access to the disk-image contents: ftp://url/path/IMAGES/DISK99 # points to sector image ftp://url/cpmfiles?i=DISK99 # contents of DISK99 cgi cpmfiles takes one arg (i) that's the image to mount. Then you could have it all; and there would be no chance for the files to get out of sync. This could be generalized on Real OSs such that $ cpmfile DISK99.img --extract DDT.COM (where DISK99.img is a CP/M image file) extracts DDT.COM and leaves it laying about. All sorts of obvious creeping featuritis comes to mind: $ cpmfile *.img --list SID.COM I hand-wave CP/M diskette geometry issues as obvious (--geom spt/tracks/skew/sides/etc).

Solution: don't keep funds in your PayPal account. As a seller, I do a few dozen PayPal transaction each month, mostly to buyers outside the USA. In fact, when I get a large (over $200) order from my web site from a first-time non-USA buyer who wants to use a credit card, I will usually insist that they use PayPal instead (since I have near-zero recourse if the buyer uses a hot credit card). At the end of the day, I transfer all of my PayPal receipts to my bank account, so PayPal can never "seize" my funds. I've never had any problems with PayPal, (except that their site is God-awful slow and their "send invoice" procedure is clunky and time-consuming) and the fees they charge are about the same as what I pay my merchant processing company for charge card transactions (about 3 percent).

I got the same story from an IBM marketing rep when I wanted to take an (original) US-use PC to India to run on 220v 50Hz. He was right, but for a reason that I hadn't considered. In the old 60w PC power supplies, the fan is AC-operated and is specific to the line voltage stamped on the nameplate. I simply replaced the fan with a DC-operated one (maybe it taxed the meager +12 supply a bit, but hey, it worked) and bundled the unit off to Bangalore where it put in several years of service. I don't know if the same situation obtains for you, but you could also just keep the box and substitute the innards from a generic PC power supply. I was looking through the stuff in my garage and noted that I still have a carton of old PS/2 Diskette Adapter/A (5.25") boxes. These were surplused by IBM and the drives themselves scavenged for resale, but I've still got the cases complete with power supply and cable and hardware (including the tamper-proof Torx screws) in their original shipping boxes. They're really very well constructed units. Anyone interested?

It's not unheard-of for SMPSUs to contain a mains-frequency transformer, running off the AC mains, to provide the startup supply (or maybe all the supplies for the control electronics). If that's the case, you do need to do more than change the rectifier for a voltage doubler circuit to get the right DC voltage across the mains smoothing capacitor I would be _very_ suprised if this thing cared about mains frequency (within sensible limits). I can see no reason why giving it 220V from a step-up (auto)transformer wouldn't work. -tony From cisin at xenosoft.com Wed Sep 21 19:36:30 2005 From: cisin at xenosoft.com (Fred Cisin) Date: Wed, 21 Sep 2005 17:36:30 -0700 (PDT) Subject: Elephant Memory Systems tribute page In-Reply-To: <200509211336170398.15A7DDF6@10.0.0.252> References: <200509211336170398.15A7DDF6@10.0.0.252> Message-ID: <20050921173540.C84509@shell.lmi.net> > >http://home.comcast.net/~kevin_d_clark/ems/ On Wed, 21 Sep 2005, Chuck Guzis wrote: > Quite possibly the worst diskettes, except for "Brown Disk" diskettes that I ever used!

I simply Interesting... The IBM PC and PC/XT power supplies that I've seen over here are, of course, designed for 230V mains. I am pretty sure they're made by Zenith. From what I remember, the fan is a 12V DC one but there is a mains-frequency transformer with a 115V primary (!) connected between one side of the mains and the centre-tap of the mains smoothing capacitors. A bit of thought shows this is OK... There is an internal link that converts the input rectifier to a voltage doubler and in the process connects this transformer across the mains. In other words it sets it for 115V. The PortablePC is similar, but there's a user-accessible switch to set the input voltage. It does much the same as the intenral link on the other supplies. -tony From chrism3667 at yahoo.com Sat Sep 17 09:53:25 2005 From: chrism3667 at yahoo.com (Chris M) Date: Sat, 17 Sep 2005 07:53:25 -0700 (PDT) Subject: VCF 8 question Message-ID: <20050917145325.45188.qmail@web61017.mail.yahoo.com> sort of a vague question, that will undoubtedly be met by a vague response.

Those are much newer than the 586 which is a five-user 8086 system. Good news- I've heard back from the person who won the bidding on eBay. He didn't get a working boot diskette, but he did get (this is what has me excited about this) the Development Tool diskettes. With what Pat has said he probably has and these other disks, we may be able to pull together a good robust system setup for the Altos 586. I pointed him at Dave Dunfield's site where there's a boot diskette image, and recommended he contact Dave through the site about getting his disks imaged and available. He also got a lot of paper documentation. It will be really great if the OS and a C compiler comes together out of this. Then we can start porting over the classic UNIX sources and make these Altos boxes come alive again in a real way (a vintage UUCP network??).

Hook all three secondaries together in parallel, then use one of the primaries as the primary and hook the other two secondaries series-aiding to make the 220 volt 'secondary.' Doesn't even matter that much what the secondary voltage of each transformer is, as long as they're identical. A crude, big, heavy, lossy solution, but workable esp. since it's not that hard to find three matching 'boat anchor' transformers at some surplus outfit.

Just watch your phasing; get the leads swapped to one of the "other two" transformers and you'll get (nominal) zero voltage instead of double voltage. Indeed, you can do something autotransformerish with only two transformers: ---------------------. IN | --------+------------|------------------------------- | +----+ OUT | | | +------------- | | | | |_()()()()()_| |_()()()()()_| _==========_ _==========_ | ()()()()() | | ()()()()() | | | | | +------------|----+ | +-----------------+ Of course, the three-transformer version produces double voltage that's isolated from the input, whereas the above doesn't. Also, you still have to watch the phasing; get a winding's leads swapped and you get zero voltage instead of doubled voltage. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From healyzh at aracnet.com Wed Sep 21 21:24:48 2005 From: healyzh at aracnet.com (Zane H.

I've had several people try to buy the machine, but the sales have fallen thru for various reasons. I originally thought I had to have the machine sold and gone by the beginning of aug, but I got an extension to the end of sept. for the storage space. Unfortunately the sale that was suppose to move the machine last weekend has seems to have died. If I don't hear from the buyer by tomorrow, I ll need to find someone else to take the machine. So I am starting now since I am running out of time. After my original post several people said I was asking too much money (~$500), but other people seemed to be interested. Is there anyone that can pickup a VAX 11/750 at a location ~40 miles west of Chicago this coming weekend? If you can pickup the machine this weekend it is yours. Pay me what you think the machine is worth, and if you have to spend the money on a truck to transport the machine instead, then so be it. I really want to see the machine saved. Let me know ASAP. If I get no responses by Friday, I'll have to make arrangments to have it hauled away for scrap on Monday. It has to be out of the storage space by Monday evening. Following is a list of what is included.

Depending on what you are replacing the PLC with and even with the proper Westinghouse software, you may end up just being able to open the files on the customers backup and print them out. You are not guaranteed any equivalence of functionality by copying the program. If you are desperate to find the contents of the PLC program, use a hex editor or a simple ASCII editor (notepad) to open the file. Some of the older PLC programming software packages kept all their files in ASCII format. You may be lucky. Last suggestion. I am guessing you are upgrading the PLC for some reason, presumably with something a little more powerful than the original Westinghouse PLC. You may want to change the control algorithms to provide a better control of your process. Good luck.

For OCR, it may depend on the OCR software, but for almost everything I have found that 300 dpi and gray-scale (8 bits per pixel) JPEG works best. Grayscale is definitely better than black-and-white (1 bit per pixel) for reproduction that is indistinguishable from the original, but for some OCR software, black-and-white line art (1 bit per pixel) may work better.

The carnage has begun. I picked up an interesting looking DEC user guide for the MRV-11D prom module. If any one would like it (I don't have a scanner), let me know. If there are any specific boards anyone is looking for send me a private email. The folks next door did have someone stop by and make an offer on the entire lot, offer was not accepted. The only offer that was considered, was on the DEC microfiche. I also saved a few sets of IC Masters dates from the 80's and 90's.

Plastic Message-ID: <200509220636240100.12167E5F@192.168.42.129> Hi, gang, Got a couple of 3M telecom test sets (965TD's) that need some cosmetic help. No, they're not off-topic. First, they both use an embedded DOS-based computer, and second they're both over ten years old. Anyway... The outer housing is made of (I think) high-density polyethylene, the same stuff that the outer jacket of telephone cables is made from, molded in bright glossy yellow. At least it was bright and glossy when new. As one might imagine would happen with field craft instruments, these have been dinged and marred pretty badly. My question is: What's the best way to restore them? I've tried simple plastic cleaner/polish, and it helped a bit, but the scarring is still there. What I'd like to do, ideally, is take enough of the outer layer off to smooth things down, and then polish it up so that they look new. With that in mind: Anyone know a good way to recondition HDPE? Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

First, having to transfer funds out of your account every night is a PITA! Especially for someone that only uses PP occasionally. Second, how do you stop them from taking the funds out of a future payment? What are you going do if they do take the funds from a future payment, refuse to ship the merchandise to that buyer? For me it's a lot easier to refuse to take PP and insist on a money order, check or cash.
