To get to the point, this advice was golden. After stripping away the 220, 8K2,6K8 and the 56K to Vcc, the unit started functioning. A nasty 60Hz blip was removed by slightly biasing the negative input with a 1M resistor to GND. The 1M drive to ground pulled the input over so much lower, making the center around .7V, so I used Tony's idea to create a .7V reference on the + end with a forward biased diode and a week pullup to Vcc, which made things ever so much better. Obviously, given the LM339 issues, this is unworkable in the end, but it did get me to realizing some outputs on the LM339, so thanks to both of you. I can plainly see the oscillation on the comparator transitions, so it is obvious I need a better comparator. I'll have to source a few different comparator options from Digikey to fill my parts box. Suggestions are welcome. > Using the internal AVR comparator sounds like a better final solution (fewer components), but in devising an > input circuit for the AVR you may be running into the same issue of loading a high-impedance source. Though it plays into Tonly's notes about my analog understanding (or lack thereof), I was so disillusioned by the analog uncertainties that I initial focused on the AVR comparator. By correctly biasing the comparator, I was able to get much better results tonight, but the lack of any ability to add hysteresis into the design hindered my success. At transition, the signal simply bounces badly. I tried to construct a low pass filter (22pF and 5K6), and some variations, but I was not able to overcome. I then tried to deal with it in SW, but I have not yet been successful.

Thank you, I already got results for a VT220 from another contributor. > Note that the setup probably can alter the results. I had "Auto Wrap" > enabled, which is probably what you want. Quite right. The test actually turns on auto-wrap itself. I even ran the test on a VT100 emulator in Javascript (http://www.pcjs.org/devices/pc8080/machine/vt100/), which emulates the VT100 hardware with the original ROMs. There is a configuration with a VT100 connected to an IBM PC AT, so after installing Microsoft C on it and porting the test to MS-DOS, I got the same result as a genuine VT100.

Even Ritchie Lary, the author, no longer had the source when Eric Smith inquired some years back (~2011 - 2012), and Ritchie did not think that anyone else was likely to have it. So, it appears to be lost forever. I love to hear whether somebody has that source code! But then, I lack the tools to compile that. IIRC, you need a microcode compiler and some other tool ?

Presumably. But it's not easy to replicate the work of a wizard like Richie Lary. The microcode assembler is probably less of a problem. Another issue would be to reconstruct the RSTS support code for loading the microcode and running PDP8 jobs, which doesn't seem to be around anymore either. paul From dkelvey at hotmail.com Wed Mar 1 11:56:49 2017 From: dkelvey at hotmail.com (dwight) Date: Wed, 1 Mar 2017 17:56:49 +0000 Subject: Cassette Interface Assistance In-Reply-To: <86065efc-6bea-7f7d-549f-c48659186f1b@verizon.net> References: <5a490b41-7ee9-5147-ff1e-c40c37a61ebb@jbrain.com> , <86065efc-6bea-7f7d-549f-c48659186f1b@verizon.net> Message-ID: I'm not sure how something as simple as a cassette interface could be causing so much issues.

CDs have been mailed to users with current update subscriptions, and the free Demo version may be downloaded from www.dbit.com/demo.html as usual. E11 V7.3 has the following new features: - My favorite one: a BREAKPOINT command which accepts arbitrary boolean test expressions, compiles them into native x86 code (to reduce the speed penalty), and incorporates them (until disabled with BREAK/CLEAR) into the main fetch/decode loop). Examples: break pc >= 2000 and pc < 3000 and @(r4+4) = 42776 (range of code with specified value in block pointed to by R4) break ci(pc)&177400 = 104000 (about to fetch an EMT instruction) break phys(14634520) <> 3044 (location at physical address gets changed from expected value) Errors at run-time are silent. If a specified test causes a bus timeout, odd address trap, or division by 0, the test fails. Well OK division by *constant* 0 gives an error but I just mean nothing damaging happens if the registers aren't pointing where you thought, etc. - A few rare antique emulated devices: DC11 SLU. Basically similar to the DL11 (ignoring the extra CSR bits and programming it like a DL11A works), but it also has a settable baud rate and modem control which is different from how it was done on DL11s. - Also the DM11 single-speed serial mux (not that E11 minds running each line at a different speed, but the original did). It uses DMA for transmission but also for reception into an in-core FIFO which the documentation adorably calls the "tumble table". And yes this is the origin of the DM11BB modem-control option more commonly used on the DH11. There's a new command to tell DM11BBs which to attach to (the default is still the DH11 with the same controller letter). - Finally, the justifiably forgotten TR79F 1600 BPI tape controller for TR79 drives (really HP7970Es), which includes the parity track in core with each byte of tape data taking up a word, so it's a pain to program. But it had 1600 BPI pretty early. The only driver I can find for the TR79F is in the "TRDP" version of XXDP, which is on Bitsavers as a scan of a microfiche of the listing. It can be used to load the ZTRAB0 diagnostic (the only other program I know of for the TR79F), but of course the test immediately trashes your boot tape. I felt dumb. - Driver for raw ATA/SATA/ATAPI disks (DOS and stand-alone versions). - Driver for National Instruments PCI-DIO-96 digital I/O card (DOS and stand-alone versions). It's a bad fit to emulating the DRV11/DR11C (ASSIGN OA: DIO96: does work but you'd have to wire up an adapter with buffering since the drivers are rated at only 2.5 mA) but it's probably the most common digital I/O board around. Even though it's PCI (not PCIe), it's still made new (at great expense), but cheap used examples are everywhere. - Ability to use a digital I/O card to drive real display and switch registers. Wiring up a blinky-lights board for your $25 eBay PCI-DIO-96 is a lot easier than making one for current PC busses, even if the 100-pin D-shell plug is a pain (but AMP makes an IDC connector that brings it out to two 50-pin Bergs).. - SET HISTOGRAM command enables/disables histogram of PDP-11 opcode usage (which again is temporarily compiled into the main loop when enabled). HISTOGRAM command displays the results or saves them to a file. - EXAMINE/DEPOSIT /BYTE /WORD /LONG /QUAD switches support various data types besides just words. Finally. - MOUNT FILE.TAP /LENGTH:n or /SIZELIMIT:nMB enables emulation of EOT early warning flag (giving the approximate maximum length of the tape in feet or megabytes). Not generally needed (who minds an unlimited tape?), but some diags want to fill a tape with test data all the way to EOT. - ASSIGN NULL: /LOOPBACK switch. Does what you think. - Experimental POWERFAIL command simulates power failures on command, or SET POWERFAIL command schedules one at shutdown (with a core dump to a file). Thank you Oleg Safiullin for the idea! Might need some changes -- I've never dealt with power failures on a real PDP-11. - Dramatically improved timer precision in DOS and stand-alone versions. SET THROTTLE in particular is silky smooth, but this improvement affects many many things. - All commands that take a time duration as a parameter will now accept a decimal point and/or unit suffix. The default units are the same as in previous versions. So instead of SET THROTTLE DELAY=1 (microseconds), you can use SET THROTTLE DELAY=1.2 or SET THROTTLE DELAY=1200NS (values will be rounded if needed). I hadn't realized so many places use time values -- I might have missed something. There are also many bug fixes and minor changes, but most importantly: - WMSG.LOG file that grows and grows (in Windows versions). Sorry about that! That was supposed to be disabled in the released version. Well it is now.

But, the REAL experience did not include volume control or speaker disconnect! THAT was part of the real experience. The Computer History Museum had a running 1401 room.

The real experience also included the sudden assault on your nose when a random, and sometimes unkempt, user would grab a printout from the giant printout wall. There was no avoiding that! The users at the terminal often times were also a mixed bag and you rolled the dice and took your chances with what you'd get. There was no end to the random smells from cigarettes, to pot, to whatever crazy food was on sale in town, to lord knows what perfume or sandalwood. That part of the experience is going to be quite difficult to replicate....

They are all mechanical and stood up remarkably well to hammering away day and night printing out the console log, considering what they are, I would hardly think unreliable fits. Most of the problems where due to neglect or poor maintenance. The norm was to do a little as possible plus customers where often reluctant to give up the console for maintenance, so worm parts that should have been replaced often never did. Quite often the center bears where worn out which causes the cycle shaft to wobble a little and then you start fudging the adjustments to compensate and it just gets worse from there, but replacing the center bearing is a big job so most people avoided it. This was true of other selectric terminals as well. The OP guys ( fixed the office selectrics) would be horrified when they saw the condition of some of these machines. The last 1052 I saw operating the space cam was so worn out that it wobbled, but it still worked. The original selectric I/O was just a standard office selectric with contacts and solenoids hung off it to make it work as a terminal, or in the case of the 1052 a printer ( the keyboard in a 1052 is a keypunch keyboard mechanism). They where never designed to hammer away at the full speed 15.5 cps for hours on end. Later IBM came out with the I/O 2 which was designed from the ground up to be used as a I/O device and was much sturdier, but they came along too late for system consoles, by then consoles where CRTs and the console printer was a wire matrix printer. > > If some good quality audio clips of a Selectric were available, it should > be possible to jimmy up the console terminal emulator to make the sounds. > > So I am fishing for any existing audio clips with clean sounds, or someone > with a Selectric that is willing to make some recordings, or a pointer to > somewhere where all of this has been done already. > > -- Charles Paul.

Yes, each typed character's sound is pretty much indistinguishable, but the mind is very good at detecting the same sound multiple times in a row, so sampling a handful of strikes and picking randomly should fix that. The sound of the shift key prepositioning the typeball. The sound of " ". The CR/LF sound; at some point at might be could to have different clips of different line length CRs. I still need the "Alert Bell" sound. (From the Honeywell 6001 Operator's console, not the 360/91 fire alarm bell, though).

If one wanted to go "full immersion" it might be an idea to acquire an HTC Vive and develop the it as a simulation VR experience. Then you get the sights and the sounds. With the Vive (and not the Oculus Rift) you also get the room scale VR "stuff" and hand tracking controllers. You can add in more things than just the sounds of the terminal, you can include mundane tasks like swapping disk packs, swapping tapes, and using the various consoles and buttons on the devices. Just to point out this kind of simulation of an location with "things to do" has been done in VR. May I present to the list, for your delectation: "New Retro Arcade: Neon" It's a VR recreation of an arcade. Naturally, there's all kinds of hurdles to deal with in creating a simulation like that. First of all VR (at present) needs beefy computers (Do you have a high end gaming graphics card on a modern up specced PC? No? Then no VR for you!) and the VR hardware itself isn't cheap. Next there's the development time investment, and while the Vive's hand controllers do let you manipulate things in the VR envrionment they're most assuredly not what you'd want to use for typing at a simulated keypunch, printing terminal, or video terminal. (Though you can just use your PC's keyboard for that. And for machines that have mice (workstations, anyone?) you can also use the mouse too; light guns/light pens can be "done" with the hand controllers. Then there's the topic of *cost* you could release it for free, but there's a lot of work that has to go into the thing. Selling it for cost well, the market is limited so you'd probably not really make anything (I'd sure as hell buy it... if I could afford a beefy PC and VR hardware). And let's not get anywhere *near* the topic of including the software to run on the simulated hardware with the program. Though, if it was a simulator of an IBM System/370 ("Who wants to reimplement Hercules in a game engine? No one? Smart move...") you could throw in MVS or OS/360 since they're both in the public domain. You could provide the software as just the "naked" simulator, with the user needing to acquire disk/tape images on their own initiative, but now you've reduced the number of people from outside of the already "expert" community of us classic computer hobbyists who would be able to use the software. One could also make such a simulation in a regular 3D game engine and then bolt on VR support later. That's a much larger "market" in terms of people who could run it, though it wouldn't be nearly as immersive as a VR experience. Though it would still be fun to try. (Look up "My Summer Car" it's an indie game where a main is putting together and then driving a beat up junker of a Datsun 100A.) Anyways, I'm rambling. Cheers, Christian -- Christian M.

Well, we still had a Selectric (1050) on our 360/65 at Washington University up until the end. I'm pretty sure it was the most unreliable part of the machine. It seems about every two weeks it would break the timing belt, which meant the clutch had to be rebuilt. IBM had two 1050's there, and would swap them every time one broke. They really did run the 1050 hard on that system, it was printing a line about every 10 seconds for about 14 hours straight every week day.

The S/360 machines just pounded the hell out of the SYSLOG device. I guess the Selectrics were better than the Model B-based console typewriters, which always seemed as if they were going to fly apart. As a typewriter, the Selectric is pretty good. I still have a correcting Selectri III with a broken drive belt (I have a new belt waiting to be installed), but I haven't gotten up the courage to repair it myself yet--it's not a simple job. --Chuck From jwsmail at jwsss.com Wed Mar 1 22:52:19 2017 From: jwsmail at jwsss.com (jim stephens) Date: Wed, 1 Mar 2017 20:52:19 -0800 Subject: Full immersion emulation In-Reply-To: References: <3f760a84-2ea5-3015-efb7-b0f5caf7f651@gmail.com> <58B78FAD.9010405@pico-systems.com> Message-ID: On 3/1/2017 8:36 PM, Chuck Guzis via cctalk wrote: > That's one area where CRTs are sooo much better.

Cards and 1402 printer. So, the 1050 was not real busy. The /65 at Wash U was very heavily used, and souped up to the 9's. It had dual internal memories (as opposed to the horrible predecessor, a model 50 with LCS, which made it run slower than a /40). With the dual identical memory units, you could use interleaving. Anyway, they had 2 Memorex 3764 DASD controllers, first with Calcomp 3330 emulators, and then with Memorex 3350 substitutes. They got Memorex to hack up a version of MP65 so that they could take advantage of RPS. They also had a bank of Hitachi 200 IPS tape drives. And, so, the 1050 was just chattering away almost constantly from about 7 AM to 7 PM. I think they finally got a CRT for the tape operator. But, they kept the 1050 as main console for the hardcopy record.

So, the 1050 was not real busy. It ran MVT21 thru 1975. The MVT version of the workstation was one of the first ever run on an actual 360 in some time. Most people were using 360/20's with the RJE code supplied with Hasp. The 360/20 code was all macros and quite fun to read, whereas the one for such as the 50 was not. I know they had to fix some bugs and customize it so that they could enter jobs to both the data center in Columbia and still run local jobs. Just some magic on the job card. Normal users never saw it, but the printer code was modified to spool jobs locally for printing. the only thing that was done of a major modification is that they decommissioned the CPS system, which was the interactive PL1 system. The 2741s and controller were dedicated to a setup to allow access to TSO remotely which was in Columbia, Mo. CPS could not share terminals with any OS functions. When CPS and OS/MVT were running MVT had no clue that CPS terminal hardware was attached. You could however spool print jobs. CPS was implemented as a firmware extension, and ran in a 1mb attached LCS when it was up. With 30 2741s which I didn't mention earlier we certainly had the right CE. You couldn't interchange the type balls, but everything else worked the same. thanks jim From shadoooo at gmail.com Thu Mar 2 01:13:24 2017 From: shadoooo at gmail.com (shadoooo) Date: Thu, 2 Mar 2017 08:13:24 +0100 Subject: DEC VT30-H and VTV30-J, was VSV11 In-Reply-To: References: Message-ID: Hello, given recent posts about Unibus graphic systems, I'm coming back with a request: was anyone some documentation about board sets VT30-H and VTV30-J?

I've got a photocopied user's manual in this mess somewhere (used for the "VR:" VT30 emulation in E11). My recollection is that it was built by DEC CSS UK, but even if true, that doesn't mean they couldn't have farmed out the design and/or PCB layout.

The one on the 360/67 at Newcastle was utterly reliable, as was the 2741 we had on our remote connection, and also the same unit in the 1130 console. The usual reason for belt breakages is contamination with oil which attacks the rubber so perhaps there was some over enthusiasm going on here. On the other hand I do remember that the CE who came into the IBM Manchester (UK) office to fix the IBM 1800 based PABX https://en.wikipedia.org/wiki/IBM_1750,_2750_and_3750_Switching_Systems used to curse, as the 2741 console on that was usually switched off, so got gummed up, and required a clean and lube before he could start work on the PABX....

After you change a few dozen it gets pretty routine. One of the banking terminals I serviced would jam mid-cycle if the type ball hit the line finder on the document feed, and since thy had a stronger motor than the OP selectric it would at least tear teeth off the belt if it didn't break it. In some banks the terminals where set into the counter so the bank's customers would come by to offer their sage advise while you had one torn apart for something like a motor belt. Paul.

Manchester University has found a disk pack that is promisingly labelled. The disk pack has been provisionally identified as an ICL EDS8, apparently compatible with an IBM 2311 and with the mechanical assembly based on a CDC 9450. The University has asked The National Museum of Computing (TNMOC) is they have a drive that could read this disk pack, but it seems that although they have such a drive, they have no plans to restore it.

I have played with Cortana and it's decent. It is the beginning of something useful. But I have, for instance, a blind friend who has an Amazon Echo and he likes it. It can control his lighting & heating for him, two things difficult for blind people to do. He also uses Siri a lot on his iPhone and it too works well for him. We both find it ironic that an almost-buttonless phone is the most accessible to blind people, but it is and it works. Now with Siri, it's better. He just dictates text messages and emails and it can spell better than he can.

Oooh, good catch. I hadn't looked carefully at those faint images, I was just looking at the brochure which had the separate images. > Not nearly as cool as an Enable :). Yes; the ENABLE was pretty clever: it used an MUD backplane as an EUB backplane, to hold the ENABLE and stock EUB memory cards; both the CPU _and_ DMA devices were on the incoming UNIBUS, and the ENABLE could tell whether a read-write cycle was from the CPU, or a DMA device (if you look at the UNIBUS spec, there's just enough to do that, even without being able to see NPG), and routed it through the appropriate mapping, depending.

I am selling my house and in the back of the garage is a complete System/32 that was working when I stuck it there and covered it. Much other stuff is in front of it so I haven't seen it in a while. It's free for the taking to anyone willing to come to East Lansing, Michigan and pick it up. If you aren't interested then it'll just go to the scrappers because I need to get the place ready for inspection. The junk haulers should uncover it in a day or two at which point I could take pictures. > > I also have a PDP-11/60, if you know of anyone interested. Same deal - free, come pick it up. The 11/60 main box has been stored in a dry basement along with two RL01 disk drives (in free standing cabinets, not rack mounted) along with a box of flat interconnect cables. It was used in a cardiac unit to run heart monitors and has an extra card cage full of interface cards. Also there's 3 PDP-11/34s in a rack in the garage as well. All this stuff has to go in about a week to 10 days, unless arrangements/promises are made and kept. > > If you're interested in any of this stuff, or could refer me to someone who might be, I would love for this stuff to go to a good home.

It wasn't a computer, but the first commercial frequency-synthesized scanning receiver, the Tennellec Memoryscan, circa 1974, used a binary keypad. It came with a fat book listing a 16-bit binary code for each frequency the scanner could receive. You could program up to 16 such codes into the scanner. My grandfather bought one for my grandmother when I was 10 years old, and I was put in charge of programming in the codes for the frequencies my grandmother selected. Since I already new binary, I worked out formulas for the codes so that I wouldn't have to use the book. That way I could program the scanner in only ten times the time. It did come in handy some years later when my grandmother wanted to changes the frequencies, but the code book had been lost.

The entries up to #13 match the IBM. I think #4 and #20, IIRC are the common ones you see as evidenced by a sticker on the case behind the plasma display. The Roms are simple to modify, if you know that they are Even / Odd for a 16 bit total width. you will have to figure out a new checksum and modify the last byte of the rom to come up 0. Again, if i recall you need to make the overall sum come up = 0. I always read the rom from high memory into ram and wrote a simple loop to add up the checksum in AL. The play with the last byte till you get it back to 0. I ran Pick R83 on all of mine, with an 8way and streaming tape card in the expansion bay.

Max drive size was 500mb. You can use larger but the first partition must be 500mb and the second is only usable to the limits of the OS version. For example the hardware (BIOS) will boot the OS in the first 500mb partition and of the OS such as Win3.11 can handle up to only 500mb if memory serves but there can be many partitions. The other thing is the BIOS much be able to setup for the drive geometry, some only have a predefined list. That machine was seen with drives in the up to 340 or 420mb scale over time and larger than 40mb was not uncommon. If you can find a working ST3660A (500mb) that might be a good one to go with. I'd max the drive at 1Gb. Larger may not work.

Yes, that's my concern. I thought it may even be expecting something like XTA, but I suppose that doesn't really make sense given the '286 or '386 CPU (I only picked up the Portable III last weekend and I'm not sure which CPU it has - I believe that the later ones had the '386) > 1) If you are going period OS, get Compaq MS-DOS V3.31. Anything prior to > that is limited to 32MB per partition. Well, I suspect 32MB will be plenty :-) I don't think I've ever actually tried putting a large-capacity IDE disk into a machine which was designed for something much smaller (I've always had a stash of period drives kicking around in case of failure). I'm not sure if it all gets translated into a linear address somewhere between system and drive anyway[1], so I can pretty much pick any BIOS drive type and expect it to just work (obviously at massively-reduced capacity!), or if the drive really is addressed via CHS and so I need to pick type[2] carefully (or look into LLF). [1] And I know that I used to know the answer to things like that, but it all fell out of my head years ago :-( [2] Maybe picking something that's "smaller in all dimensions" works, though? It would waste some enormous number of sectors on each track, but that's not really an issue if it works! > 2) You may want to use a "disk manager overlay" to be able to use specs > other than the BIOS ones: > http://www.seasip.info/VintagePC/compaq3.html Aha, some useful info there - thanks! cheers, Jules > > > From jules.richardson99 at gmail.com Fri Mar 3 16:48:11 2017 From: jules.richardson99 at gmail.com (Jules Richardson) Date: Fri, 3 Mar 2017 16:48:11 -0600 Subject: Cekit 8085 micro trainer Message-ID: I picked up a Cekit 8085 microprocessor trainer last weekend, model MT-01.

There's nothing really specific that I wanted to know, but it's just odd that there seems to be no info out there at all about it. Some of the writing on the PCBs is in Spanish, and it says on the back that it was made by Cekit for EKI - but throwing that into the Google pot doesn't appear to be of any help. I'm not even sure how old it is. The CPU, I/O chip and some of the logic is dated 1983/84, but then there are a handful of Goldstar 74LSxx ICs with 90xx codes on them.

(1023 Cylinders, 15 heads, more then 17 sectors per track) If you can find the Compaq EGA board, it will work with the internal monitor, and provide almost usable Windoze.

Or else make them dit and dah (like on a Morse keyer) so you can have alphanumeric entry? Eons ago a friend of mine wanted to design an audio protocol (e.g. using a Votrax SC-01 and an ADC), figuring that the word "ZERO!" has a lot more of a high-frequency component so it wouldn't take much processing (this was in 8-bit days) to distinguish it from "ONE!". The snag was that he wanted to add "WHAT?" as an error-correction feature.

Much of the trove had already gone to scrap before this group got wind of it. And for a lot of it that was probably the right thing though it pains me to say that. The house cleaners had been there before I contacted the owner immediately after the message appeared on the list. The S/32 all went to scrap as it had been a possum home for a number of years, the 11/60 cabinets were scrapped a few days prior to the list contact and the 11/34 had also been severely damaged by animals while being stored in a garage for approximately 10 years. The 11/60 processor was stored in better conditions and consists of two BA11 style boxes. There was a well preserved Flexowriter recovered in pieces, but likely complete, and a bunch of ADM3a terminals. I also brought home a very, very rough TU 55. Unfortunately another, possibly a TU 56, had been scrapped a few days earlier as well. The owner, Greg, was one of the nicer people I have met over the years. He lives near the MSU surplus sale site and was a good customer there. We need a better way to be recognized as a place to post situations like this earlier in people's decision process on how to clear out a house. BTW, I should also report on the recovery of the Triad system early in January. Will Donzelli and I came back from that location with the Triad rack, a re-badged Interdata system (8-32) and a lot of interesting terminals as well as a few CDC 9726H cartridge drives. We may have a system for this, but have not had time to investigate.

The via ctalk is useful as a target for filtering the traffic. For some reason there is leakage of detected emails on google. It is perhaps due to prior mentioned non conforming emails of some sort, don't know, their filtering sucks. But it may be that that will allow me to catch more if not all of the cctalk traffic in gmail. I'm subscribed three times for archival purposes. I read via an email subscription that ends up in a Thunderbird file via pop3 from that server. Never misses with the email rule. I wanted an outside the building forget it archive I could peruse, so created a subscription into my gmail account. That one is leaking about 1 to 5 messages a week using the same rule as Thunderbird, which is based on email to / from etc. And a third subscription goes to an account on a server which pulls everything via fetchmail. That subscription has nothing but Cctalk on it. i have it as my main archive if all else fails. (and Thunderbird is getting flaky, and has failed). If the via cctalk stays, I'll try looking for that. I had asked jay eons ago about a [cctalk] prepend on the subject and his and others opinions was that that was not desirable. However it always works on all lists I have for filtering. Maybe putting it in the from will be unobtrusive enough people will put up with it, and maybe Google's filtering won't suck with a rule hitting that field. thanks jim From pbirkel at gmail.com Sat Mar 4 02:49:23 2017 From: pbirkel at gmail.com (Paul Birkel) Date: Sat, 4 Mar 2017 03:49:23 -0500 Subject: PDP-11/60+RL01 Recovery (was: Re: IBM S/32, PDP-11/60+RL01, PDP-11/34, East Lansing MI) Message-ID: <0f4701d294c4$392591b0$ab70b510$@gmail.com> -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Dan Cohoe via cctalk Sent: Friday, March 03, 2017 10:45 PM To: 'General Discussion: On-Topic and Off-Topic Posts' Subject: RE: IBM S/32, PDP-11/60+RL01, PDP-11/34, East Lansing MI -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Steven Maresca via cctalk Sent: Friday, March 03, 2017 11:59 AM To: Noel Chiappa; General Discussion: On-Topic and Off-Topic Posts Subject: Re: IBM S/32, PDP-11/60+RL01, PDP-11/34, East Lansing MI On Fri, Mar 3, 2017 at 11:48 AM, Noel Chiappa via cctalk < cctalk at classiccmp.org> wrote: > > Is anyone confirmed to be picking this stuff up?

Or buzz? We had a TU77, and when we ran backups, it made a loud buzzing as it was doing start/stop about as fast as it could go. Or, are you referring to the whine as it went into rewind? The 200 IPS Hitachi drives on our 360 were much louder in the rewind, you could hear it anywhere in the machine room. Jon From nf6x at nf6x.net Sat Mar 4 15:27:03 2017 From: nf6x at nf6x.net (Mark J.

The computer floor at CDC SVLOPS had perhaps 15-20'high ceilings with terrible fluorescent lighting. Apparently, it was originally intended as a manufacturing floor. At any given time, there were several system, oceans of disk and tape drives around, along with the usual printers, readers and punches. Talking to someone meant getting up within several inches of someone and raising the voice to be heard. All hard surfaces--nothing sound-absorbent in the least. Having spent a lot of time in a steel mill, I'd say that the noise level was comparable. And, between the over-enthusiastic air conditioning and background noise, one's nerves were pretty frayed at the end of a shift. > In my experience, visiting a computer room was enjoyable, while > hanging out there for a full shift got rather tedious.

During the OPEC oil embargo in the 1970s, this then-California resident was sent to the Twin Cities in January for some work at the Arden Hills plant. Even the Ramada Inn kept room temperatures down. In the offices, there was ice on the *inside* of windows. I discovered that if I took a pillow and a good book to the ADL building, the most cozy place in all of Minneapolis most likely was in the STAR-100 room, nestled between the SBUs. My hearing is okay, but I do have a problem with tinnitus and loud sounds severely distorting. However, I can still hear the birds singing, so life is good. --Chuck From cclist at sydex.com Sat Mar 4 15:39:30 2017 From: cclist at sydex.com (Chuck Guzis) Date: Sat, 4 Mar 2017 13:39:30 -0800 Subject: Full immersion emulation In-Reply-To: References: <03619753-f8df-8cc6-c3a0-ceb390fd1db6@sydex.com> <6B77035D-F61F-4304-B656-39F1264E1559@nf6x.net> <58BB2FFB.9000008@pico-systems.com> Message-ID: <0ef13fb0-90ad-5443-2794-d3bf7988b07e@sydex.com> On 03/04/2017 01:27 PM, Mark J.

You could tell from across a noisy computer room when one of the guys was running the tape I/O section of the Navy COBOL audit tests. The short-record section made a 607 or 657 tape drive sing quite loudly. I believe that attribute was used for the CDC rendition of "Anchors Aweigh"... --Chuck From wkt at tuhs.org Sat Mar 4 16:35:02 2017 From: wkt at tuhs.org (Warren Toomey) Date: Sun, 5 Mar 2017 08:35:02 +1000 Subject: Help needed for Unix anniversary in 2019 Message-ID: <20170304223502.GA27889@minnie.tuhs.org> Hi all, some of you may know me as the guy who runs the Unix Heritage Society and the archive of old Unix systems: https://minnie.tuhs.org/cgi-bin/mailman/listinfo/tuhs, http://www.tuhs.org and http://www.tuhs.org/Archive Mid-year 2019 is the 50th anniversary of the creation of Unix and I've been quietly agitating for something to be done to celebrate this. Up to now, there's been little response. The original Unix user's group, Usenix, will hold its Annual Technical Conference on the west coast of the US at this time, so it would make sense to do something in conjunction with this conference. Some suggestions: - a terminal room with a bunch of period terminals: ASR-33s, -37s, VT100s, VT102s, VT220s - these connected to emulated Unix systems either locally or via a terminal server and telnet to remotely emulated systems - some graphical terminals: Sun pizza boxes, a Blit would be great - if possible, some actual real PDP-11s, VAXen - emulated systems: V1 to V7 Unix, 32V, the BSDs etc. In fact there are plenty of Unix versions that we could run in emulated mode. - Unix of course was one of the systems used to implement the Arpanet protcols, so it would be interesting to get some of the real/emulated systems networked together - how about an emulated UUCP network with Usenet on top of it, and some mail/news clients on the emulated systems. - retro workshops/tutorials: how to edit with ed, using nroff, posting a Usenet article, dealing with bang paths. I'm proposing to gather a bunch of people to start the ball rolling on the technical/demonstration side. We'd need people: - with terminals, portable PDP-11s and VAXen, Sun boxen - prepared to set up emulated systems - who can help bring the networking (UUCP, Usenet, Arpanet) back to life - willing to write and run workshops that show off this old technology - to help set up terminal servers and all the RS-232 to telnet stuff Some of this we can start doing now, e.g. rebuild an emulated Arpanet, UUCP, Usenet, get emulated systems up, build front-end telnet interfaces. Is there anybody willing to sign up for this? I think once we have some momentum, we can tell the Usenix people and get some buy-in from them. Post back and/or e-mail me if you can help.

Hmmm, on our TU77, the vacuum pump was not that audible, but then it was in a room with a LOT of noise. Liebert air conditioner, 11/780, RM05, RP07 and then the TU77. When the drive was not running flat out, the bup-bup from the tape columns was not real loud, but when you were pushing data fast, like BACKUP with /buffers=5, it made a pretty steady BRRRRRR noise.

The BA11-K had that incredibly heavy H765 power supply, maybe it was too heavy to safely rotate? > I'm not sure what the original part number or manufacturer was. Anyone > have this information handy? Anyway, I've seen BA11-K boxes with several different kind of mounting slides. The tall, grey-coated ones are made by Chassis Trak, a division of General Devices of Indianapolis. The 4 I looked at, all idential looking (except for handedness), all had different numbers on the CT sticker, so I don't know what the model number is! This one says '060RH'. I've also seen BA11-K's with narrower (height-wise) slides, in some sort of bright metal finish. I don't know who made those. GD is still in business; I looked on their web site and found similar slides. I didn't order any because they were kind fairly pricy. BTW, does anyone know that they grey coating is? Is it some sort of phosphate plating, or perhaps some sort of early powder coat, or what? Mine are rusty, and I'd like to blast them and get them re-coated, but I can't figure out what that coating is. Noel From nf6x at nf6x.net Sat Mar 4 22:35:34 2017 From: nf6x at nf6x.net (Mark J.

The two I've had - both 11/34A versions, if it makes a difference - both rotated. I no longer have most of the 11/34 docs, but according to the Field Maintenance Print Set (MP00082 11/34A) on Bitsavers, the BA11-KE and BA11-KF had the "SLIDE, 3 POS TILT" described in drawing D-PS-1211825-0-0.

Right now in the server room here at the house it's at 77dB -- well, right at the server rack; it's a bit lower where I sit. There's only 7U powered up right now, though, and the x3850 doesn't have its fans on due to the open windows and pleasant conditions outside. So, it could be worse -- and has been. For instance, I could turn on the G5 RackMac to measure it, but since I have those windows open it would only piss off the neigbhors :-) (ok, ok, once the OS takes over the fan control, that one drops to only "pretty annoying" from "banshee". Where did Apple get these damned fans from, anyway?) mcl From linimon at lonesome.com Sun Mar 5 02:19:54 2017 From: linimon at lonesome.com (Mark Linimon) Date: Sun, 5 Mar 2017 02:19:54 -0600 Subject: Full immersion emulation In-Reply-To: References: Message-ID: <20170305081954.GC32411@lonesome.com> On Wed, Mar 01, 2017 at 05:22:10PM -0500, Christian Gauger-Cosgrove via cctalk wrote: > Don't forget what a machine room and the equipment looks like.

Given the possibility that you don't, my comment here is that your request for internal documents are somewhat vague. Can you be somewhat more specifics? The reason specifically I'm asking, is I was reviewing an old Unix book/document earlier, "Life with Unix" by Don Libes & Sandy Ressler. The document makes a lot of comments about both Berkeley/BSD and AT&T, and how AT&T was using Unix internally all over the place. It is of no direct value here, but the book is available to the public in pdf format here in case you are interested: During my time in the military, I spent most of the early 1990's in the Pacific theatre, and although at the time I was not wearing a Unix admin hat, I was reminded by the book that I observed AT&T 3b2 systems in Japan on base that were part of the telco system, and had no IT usage. And to be more specific, I'm wondering out loud here if possibly, the documentation you might need may not be directly accessible, but that information might be available in a round about way, possibly thru the telco side of things. If nothing else, food for thought.

Well, there are "daylight" type fluorescent bulbs. Those are quite good. We've had them around the house (my electronics workshop and our home office) for years now. The more modern replacement would be daylight (5500 K) LEDs, and in fact you can get LEDs that fit in fluorescent fixtures, either as is or (probably a better choice) with the ballast removed.

The fixtures themselves were so high that they *did* make for some recreation. Bored operators would engage in late-night "ring toss" with magtape write rings to see who could land the most on top of the fixtures. I'm sure that the maintenance people detested getting the big ladder out and clearing them off the fixtures, but they weren't around at 2AM to observe the evil deeds. I don't recall many who used those yellow rings for their intended purpose. It was just too easy to forget to remove one. You mounted tapes without and reached around the back of the reel with a punch card and tripped the "finger" that detected the ring. So the things accumulated in great piles. This probably changed (I don't recall) when the 66x auto-loaders came into the picture. --Chuck From witchy at binarydinosaurs.co.uk Sun Mar 5 12:25:43 2017 From: witchy at binarydinosaurs.co.uk (Adrian Graham) Date: Sun, 05 Mar 2017 18:25:43 +0000 Subject: FW: More 8085a oddities In-Reply-To: Message-ID: Hi folks, I didn't see the message at the bottom of this one arrive since I think I sent it JUST as the list software was being changed over.

No change in behaviour though. I'm baffled as to why the upper address bus doesn't blip once RESET goes high. HOLD is permanently pulled low so it's not that. Any suggestions?

By that I mean the processor locks up after only a few cycles so doesn't get as far as attempting to read anything, when it freezes the S0/S1/WR status lines are all high which shouldn't be possible since S0/S1 high should be 'Fetch' according to the manual, not WRITE. Vcc, RESET and clock are good and I can't see any other external signal which might hold the CPU. The PSU is good and putting out +5/+12/-12 as it should. CPU checks out in another 8085 system I forgot I had. Interestingly my analyser shows the upper half of the address bus doesn't change while the lower half manages a single transition, as does the ALE signal. From the CPU both halves of the address bus go directly to a 74LS373 each which both check out OK on a breadboard circuit I made up earlier. ROMs are all OK and the lines themselves back to the LS373 and CPU check out with little resistance. I'm stumped and can't help but think this is something stupid which I'm overlooking. Maybe more sleep will help.

So, was the write enable state latched at some point in the loading cycle on those drives? That surprises me, because I would have expected the write enable sensor to interrupt write current as combinatorial function on the drive, and/or pass sensor status up to the formatter a combinatorial signal. -- Mark J.

Yup. You loaded the tape, then bumped the "finger". As I mentioned, this worked on 60x and 65x drives. Since the autoloaders closed the door as part of the cycle, this probably didn't work for 66x. This actually worked pretty well--you never ran the risk of leaving a ring in inadvertently. The consequence of forgetting to enable write was usually far less dire than mistakenly writing to a tape that was supposed to be read-only. --Chuck From pete at petelancashire.com Sun Mar 5 11:08:15 2017 From: pete at petelancashire.com (Pete Lancashire) Date: Sun, 5 Mar 2017 09:08:15 -0800 Subject: Still Looking For AT&T 3B2 Internals Docs In-Reply-To: <20170228033340.GA19027@loomcom.com> References: <20170228033340.GA19027@loomcom.com> Message-ID: One i've had luck with is posting on Craigslist and putting ads in local newspapers to where the manufacturing was done.

In my limited experience of drives, but I expect it's typical, the write enable is electro-mechanically latched: if the write ring is present at load, a solenoid is activated which pulls the sense finger further in to hold the finger off the write ring, so it won't be a friction and wear point while running. The solenoid is released at unload.

When the vacuum motor started, there was a little air pump there that produced air bearing air (or in the REALLY bad old days, air pressure to blow the tape away from the vacuum capstans). That air pressed a finger against the write ring. if the write ring was present, the finger was blocked, and then retracted, and the write was enabled. if the finger was not blocked (no write ring present) then the finger extended and locked out as long as air pressure was present (until the vacuum motor shut off.) Some other drives had a ring that was forced back when the write ring was present. The ring had reflectors on it, and a photocell read the reflector during the tape load sequence to set the write enable FF. You couldn't just leave a probe against the write ring all the time as it would cause the write ring to work out of the groove and jam the reel hub. Mention above about the vacuum capstans. Some really old drives had two continuously counterrotating capstans with slots in them. Valves applied either air pressure, to make the tape float over the capstan, or vacuum, to make the capstan grab the tape.

Doesn't feel "really old" to me, at least. :) In the CDC drives, there was a voice-coil type valve for switching the vacuum around. I understood that the 65x units had a "cost reduced" version of the valve, from the 60x units. All in all, I much preferred the big orange 60x drives to the gray metal and blue glass of the 65x one--the 60x drives just felt more sturdy. --Chuck From billdegnan at gmail.com Sun Mar 5 14:56:53 2017 From: billdegnan at gmail.com (william degnan) Date: Sun, 5 Mar 2017 15:56:53 -0500 Subject: What's the rarest or most unusual computer-related item do you own?

Only if you don't bother editing it down to whichever address you want to reply to (as I did for this message). If your user agent doesn't let you do that, well, your choice of a crippled user agent (and an inability to edit the list of recipients is a pretty serious failing for a user agent) is not reason to mangle the list even further for everyone else. > This is *wrong* and must be corrected (i.e. removed)! I disagree. For one thing, that is one of only two places the actual sender's address appears anywhere in the headers, based on the mail I'm replying to (and the other one is in a Received: comment, even less available to user agents and not present unless the sending mailsystem happens to add it). Mind you, I'd prefer the former state. But I'm not about to criticize Jay's handling of the lists when I'm in only peripheral touch with the relevant issues; even the issue of the bounces I have only the smallest experience with. I haven't personally seen a subscription suspension since I made my mailer accept-and-drop list mail it would normally reject, which makes me think that the suspensions people are seeing are probably due to the receiving mailserver rejecting the mail and should be dealt with by the subscriber in question talking with the mailserver admin in question and getting that sorted out. > No, the Envelope-From: [...] The envelope-from is not a header and in general does not have a name with a colon after it. (Your user agent, or possibly your mail store, may be (mis)presenting it that way, but that's not how it's carried on the wire and it is not handled that way in general.) > And yes, the change in the address fields don't cure the bounce > problem because the envelope from field is unchanged (and *that* > field is used for bounces, not the header fields *within* the mail). As I understand it, the attempt to "fix" the suspended-subscription "problem" has nothing to do with where the bounces are going, but rather with their being produced in the first place. As far as I have seen described on the list, nobody knows why the bounces are being generated; there have been plausible guesses involving misguided anti-spam measures, but even those I haven't seen any confirmation of as the cause of any of the suspensions. It's certainly possible I've missed something, but the continuation of the discussion as before seems to imply that's not it. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From jnc at mercury.lcs.mit.edu Mon Mar 6 08:02:37 2017 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Mon, 6 Mar 2017 09:02:37 -0500 (EST) Subject: UNIBUS RK611 (RK06/RK07) controller available Message-ID: <20170306140237.D3D7E18C0CE@mercury.lcs.mit.edu> So I have a complete RK611 (backplane and boards, no cables, sorry).

Yes, and it must not be in the Reply-To: field because in normal cases, this field is the one used for replying, and I want to reply to the list, and only to the list. If I want to reply personally, I override the default and take the From: address instead. That's how it should work. For example, alpine ask me "Use "Reply-To:" address instead of "From:" address?" and defaults to "yes" because the former field has a higher priority.

None of these seem to be online, and I've done some exhaustive searching of library archives and the used book market to see if I can find them, but they haven't turned up any hits yet. Anyway, the documents that I think would be most useful are all listed in the 1987 and 1993 editions of the Bell Labs catalog "The AT&T Documentation Guide", both of which are posted online. 1. "3B2 Computer Technical Reference Manual" (305-490) 2. "3B2/3B5 Computer Driver Design Guide" (305-495) 3. "Unix System V/VME OEM Porting Manual" (307-780) 4. "AT&T 3B2 Computer Feature Card Interface Design Manual" (305-492) 5. "AT&T 3B2 Computer Debug Monitor Guide" (305-442) The numbers in parentheses are document numbers used by AT&T. > The reason specifically I'm asking, is I was reviewing an old Unix > book/document earlier, "Life with Unix" by Don Libes & Sandy Ressler.

One of the most useful books for this project has been Maurice Bach's "The Design of the UNIX Operating System", which describes System V Release 3 in great detail. This, combined with the SVR3 source code, have been invaluable to me. The 3B2 was the main porting platform for SVR3, so there are lots of tidbits and details about the hardware in it. In fact, without the SVR3 source code, I would be absolutely nowhere in this project. > And to be more specific, I'm wondering out loud here if possibly, the > documentation you might need may not be directly accessible, but that > information might be available in a round about way, possibly thru the telco > side of things. Indeed, there's a lot of documentation about the 3B20 thanks to the telco side of things. I haven't found any 3B2 documentation down that path, but it remains interesting to me. > Wishing you luck, Many thanks and best wishes! > Jerry -Seth From jnc at mercury.lcs.mit.edu Mon Mar 6 13:11:45 2017 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Mon, 6 Mar 2017 14:11:45 -0500 (EST) Subject: Fluorescent lights (Was: Full immersion emulation) Message-ID: <20170306191145.BE9F318C0ED@mercury.lcs.mit.edu> > From: Paul Koning >>> terrible fluorescent lighting. >> There's another kind? :-) > in fact you can get LEDs that fit in fluorescent fixtures, either as is I've been looking for LED replacements, but I haven't seen them; I'd have thought that that would be a pretty popular item, but I haven't seen them in any local stores.

I've got the T8 lights in my shop running from solid-state (GE) ballasts that I picked up perhaps 20 years ago. When I get to the bottom of the box, I'll probably replace the fixtures with LED ones, so any information like this is good to know. FWIW, they're 4-lamp fixtures (2 ballast). Replacements needn't fit the original form factor--I suspect that there are smaller, more compact LED fixtures with equivalent light output. --Chuck From abuse at cabal.org.uk Mon Mar 6 13:42:31 2017 From: abuse at cabal.org.uk (Peter Corlett) Date: Mon, 6 Mar 2017 20:42:31 +0100 Subject: Fluorescent lights (Was: Full immersion emulation) In-Reply-To: <20170306191145.BE9F318C0ED@mercury.lcs.mit.edu> References: <20170306191145.BE9F318C0ED@mercury.lcs.mit.edu> Message-ID: <20170306194231.GA16037@mooli.org.uk> On Mon, Mar 06, 2017 at 02:11:45PM -0500, Noel Chiappa via cctalk wrote: [...] > I've been looking for LED replacements, but I haven't seen them; I'd have > thought that that would be a pretty popular item, but I haven't seen them in > any local stores.

Banyan Vines sat on top of SysVR3 Unix, and we used a lot of Banyan Vines. When (Banyan) boxes went down, typically due to poor power/power outages and no UPS's, I typically got a call to recover them, which entailed interacting with the Unix underneath, until it was recovered enough that file systems were repaired and the full Banyan NOS stack could come up. Back on topic, I guess I had not understood your request enough, I had though you were needing specific hardware and CPU information.

Very interesting, I wonder if I could learn anything from Banyan Vines? I recall it on the PC, but I didn't realize it was on SVR3 as well. > Back on topic, I guess I had not understood your request enough, I had > though you were needing specific hardware and CPU information. Did not > realize that there were software/SysVR3 questions you were still asking. Oh, I definitely do still need specific hardware information. The "big" chips (the CPU, MMU, DMA controller, floppy & disk controllers, UART, etc.) are thankfully very well documented! But the rest of what makes up the 3B2/400 system board is not documented anywhere but inside the SVR3 source code. Also, if I ever hope to emulate the cartridge tape controller or the extended serial ports, SCSI, or Ethernet cards, I'll need yet more information. I don't have the source for those drivers, so I have absolutely no idea how they operate. > Jerry Kemp -Seth From other at oryx.us Mon Mar 6 18:09:32 2017 From: other at oryx.us (Jerry Kemp) Date: Mon, 6 Mar 2017 18:09:32 -0600 Subject: Still Looking For AT&T 3B2 Internals Docs In-Reply-To: <20170306232416.GA23899@loomcom.com> References: <20170228033340.GA19027@loomcom.com> <2a8850d1-37fc-4580-2ecb-7e83b5eca83d@oryx.us> <20170306190618.GA9296@loomcom.com> <20170306232416.GA23899@loomcom.com> Message-ID: <5ded7c42-aa42-7d1e-d611-7395259628fb@oryx.us> On 03/ 6/17 05:24 PM, Seth Morabito via cctalk wrote: > * On Mon, Mar 06, 2017 at 03:54:17PM -0600, Jerry Kemp via cctalk wrote: >> Very interesting.

A term common, at least in my circles in the early to mid 1990's. Banyan Vines sat on top of SysV release 3 Unix and, to the best of my knowledge, only ever ran on top of 32 bit x86 systems. Much in relationship, to, at least at one time, the Novell Netware system sat on top of DOS. OTOH, towards the later part of Banyan's existence, Banyan had decoupled their X.500 based directory product, StreetTalk. I understand that the StreetTalk was available for most common Unix's on RISC processors of the day, but my only actual, hands on experience with the directory product was on Solaris on SPARC processors. Although it has been since the mid 1990's since having any personal hands on experience with any Banyan product, I do know that they are out there floating around on the Internet. A couple of years back, I was able to obtain a copy of (as I understand) the last release of Banyan Vines, version 8.5, on 3.5" floppy disk images. Not sure if there is anything of value to you in the above rant, or if I am just reminiscing out loud to the group over decades gone-by. Feel free to reach out to me back channel if you believe I might have anything that may further your ATT 3B2 emulation effort.

In a mapped system, DCH map functions are transparent to these devices since only the 'logical' address is sent from the device to the CPU during a DCH data transfer. It is up to the specific processor and its corresponding operating system to determine how and when the logical-to-physical map. The DG hardware interface guide describes the PIO, DCH and on MVs the BMC, specifications.

Cameron, Please keep in mind that these things are rare as hens teeth, if not rarer. This is only the second or third mention I?ve ever seen of them, and the first I?ve seen of anyone having any. Please do not recycle them. If nothing else, see if you can get them to one of the museums. About the only thing I know of that?s rarer seems to be the DECnet kit for RT-11!

The retrofits I made are electrically isolated from the line, and have 88 square inches of copper PC board material to act as a heat sink. They still run quite warm, although when on, the optical output of these things is stronger than full sunlight, so they appear to be REALLY warm on the skin, so that fools you. You have to test the temperature just one second after they are turned off to get a better idea of the real temperature. I'm running about 19 W total into 20 1W LEDs, replacing TWO 48" tubes. Previous input to a 2-lamp ancient ballast was 103 W, the LED supply draws 21 W, as measured with a real power meter.

The "From:" header containing the original author's address is the cause of the unsubscribes due to bounces, and (I assume) the motivation for the recent change to the list behavior. The problem is that major production MTAs will reject (bounce) email with a "From:" whose domain uses DKIM or SPF, when the sending MTA isn't in the DKIM or SPF authorized sender list. This will almost always be true when messages are forwarded by a mailing list. Since the bounces go back to the mailing list, the mailing list software then drops the entirely legitimate list subscriber's subscription. :-( The behavior you describe is certainly correct according to the RFCs, but unfortunately now falls apart in practice. :-( From pete at dunnington.plus.com Tue Mar 7 04:58:38 2017 From: pete at dunnington.plus.com (Pete Turnbull) Date: Tue, 7 Mar 2017 10:58:38 +0000 Subject: I hate the new mail system In-Reply-To: References: <8081e31ffd8e4ce6abdcaa1c48ac16e5@livingcomputers.org> <20170228215001.D9185A58595@yagi.h-net.msu.edu> <201702282254.RAA05100@Stone.Rodents-Montreal.ORG> <3e67191c-319c-eebe-6df1-38ade2bccd6f@sydex.com> <7d5b91e2-9a85-1d9f-d29a-9a510e106c71@gmail.com> <3672896e-7498-ad86-941a-34296d007c0a@tds.net> <0625918f-47a6-4e73-6e46-396d5c9cbb06@sydex.com> <7844bcc8-c063-da0b-ad5a-0e81f7396f9f@gmail.com> <201703061330.IAA00599@Stone.Rodents-Montreal.ORG> <201703061733.MAA22646@Stone.Rodents-Montreal.ORG> Message-ID: <5c8dc30b-f205-d1fe-7bdc-5d906b5c9561@dunnington.plus.com> On 07/03/2017 09:57, Christian Corti via cctalk wrote: > And BTW, what you are doing is not clever at all: > mouse at Rodents-Montreal.ORG > SMTP error from remote mail server after initial connection: > host MX-4.rodents-montreal.org [98.124.61.89]: > 550-.de's whois server, whois.denic.de, is completely broken, handing > 550-out no contact information at all when queried for .de domains in > 550 the usual way.

Nope, that's taken from their own documentation - and it makes no difference which options I give it, or none. I didn't show all the permutations I tried, both using a standard UNIX whois client, and using telnet to port 43.

Very very kinda sortof. Netware 2 could cold-boot itself. Netware 3 & 4 needed DOS as a bootloader. If you wanted, you could issue a command: REMOVE DOS ... and then the memory was reclaimed and added to the disk cache. But if you wanted to load stuff from floppy or from a FAT C: drive, or from a CD that didn't have Netware drivers, you needed DOS present.

Given that they come from 1984 or so, they should work with the 11/780, 11/785, 11/750, 11/730, 11/725, and probably later VAXen with a Unibus. What's less clear to me is how long the drivers were supported. IIRC, the docs on Bitsavers mention support for VMS 3.x. I would rather expect support through VMS 4.X, but I wouldn't count on an SMP-friendly driver for VMS 5.X and newer unless support was specifically mentioned on the SPD. A lot of older stuff didn't get brought forward with VMS 5.X drivers. -ethan From sales at elecplus.com Tue Mar 7 11:08:37 2017 From: sales at elecplus.com (Electronics Plus) Date: Tue, 7 Mar 2017 11:08:37 -0600 Subject: 3B2 stuff-maybe Message-ID: <032b01d29765$76532fe0$62f98fa0$@com> I called the only place I know of that supported 3B2 stuff, which is Communications Hardware in TX.

Well, RFC-5322 allows a mailbox-list in the From: header, and an address-list for the Reply-To:, I don't think this is illegal. And I just noticed this RFC: 6854 Update to Internet Message Format to Allow Group Syntax in the "From:" and "Sender:" Header Fields. B. Leiba. March 2013.

In either version of the document you can see how the ISA has progressed in the opcode tables towards the end of each appendix; this might be the best original ISA reference readily available. As to the earlier ISA levels I believe their definitions were only buried as parts of the respective MIPSCO processor manuals, i.e. the R2000/R3000, the R6000 and the R4000/R4400. The latter is available online in several places; originally at and . The final version of the R6000 manual may not have been made. A very early revision was found and has been scanned and published at as tarballs of TIFF images (I have made a PDF conversion and placed the result at ). It is inaccurate and lacks opcode encodings. I have seen a copy of the original R2000 manual once, in the form of a collection of pages in a ring binder. That copy may have been lost since. Silicon manufacturers like IDT, LSI Logic, Performance Semiconductor or Siemens published their R2000/R3000 (and R2010/R3010 FPA) implementation manuals though that may serve as a reference; you should be able to track down scanned copies online.

The book ?MIPS RISC Architecture? by Gerry Kane (ISBN 0-13-584293-X), copyright 1989 by MIPS Computer Systems, has the following blurb as the preface: ?This book is a comprehensive reference for the MIPS RISC architecture. It describes the functional characteristics and capabilities of the R2000/R3000 Processors and the R2010/R3020 floating point accelerators.? I suspect this is as close to a publicly available architecture reference that exists for that generation of MIPS processors. - Rob From bulk at blit.ca Tue Mar 7 22:10:40 2017 From: bulk at blit.ca (Chris Reuter) Date: Tue, 7 Mar 2017 23:10:40 -0500 Subject: Looking to re-home some NeXT hardware Message-ID: I have some NeXT hardware that I'm looking to re-home. Items include: 1 NeXT cube with an unknown expansion card 2 Monochrome monitors 2 NeXTStation "slab" workstations, non-functional Boxed NeXTStep installation media with manuals (may not be complete) 2 Mice, 3 keyboards, various cables, SCSI drives, odds and ends. (Picture at ; the fruit is not included.) I'm located in Toronto; preference will be given to anyone who is willing to come here and haul it away. I *may* be willing to ship it somewhere, but if so, you're paying for it and it can't cause me a lot of hassle. Everything is believed to work unless marked otherwise; however, it's been years since I powered up any of these so I can't promise anything. The monitors both worked when I last tried them. One had succumbed to the dimness problem but the other was still bright, if blurry. Presumably, you could swap CRTs and have one like-new NeXT monochrome monitor. One of the two slabs would get partway through its boot sequence before hanging so it might be easily fixable. The other one was stripped for parts before I got it. The Cube worked the last time I tried it. I did, however, try to add a second drive, which didn't work. This may have screwed up the SCSI termination.

They do have to work thru ballasts and deal with starter issues that are no longer relevant, unless you remove and rewire the ballasts / starters out of the old fixtures. The things I've seen are the same form factor as a 4' dual tube dual 40 watt fixture with 110 in and light out. Pull and toss an old dual tube fixture and replace with new LED. But I've not seen the tube solution. I've got a couple of spots the tube thing would be desirable, but no source of such.

Tested yesterday too. > Sounds like it may be the whois client instead - what OS are you guys > using, and which 'whois' version? This is rather intriguing. No, not the fault of the whois client. I repeated yesterday's tests and a few more because I'd closed the terminal windows I used yesterday, and also to try to eliminate any temporary aberrations. I did wonder if whois.denic.de is actually a load-balanced server farm and I just happened to be hitting a broken member of the farm and some of you guys weren't. But that does not seem to be the case. FWIW I was using linux whois-4.5.17 originally from www.linux.it, based on the RIPE whois client, compiled locally from source under IRIX. It's part of various Linux distributions and it works on hundreds of other whois servers; I use it frequently (part of my job) and never had a problem before. That's important because when I eventually found the "DENIC Public-Whois Documentation" I noted that it recommends the RIPE whois client. So just to be thorough I downloaded and compiled the latest RIPE whois on an Ubuntu Linux system and get a similar result with a standard query. I also downloaded and tested Microsoft's whois for Windows and got the same broken result, same "Error: 55000000007 Request not clearly specified" message. More importantly, I tested connecting directly using telnet to port 43, exactly as specified in RFCs 3912 and 954. Here it is again, showing the output of the (required) HELP command: $ telnet whois.denic.de 43 Trying 81.91.170.6... Connected to whois.denic.de. Escape character is '^]'. ? % SYNTAX: whois [-r] [-T types] [-C charset] key % % where our server understands the following options: % % -r turn off recursive lookups (default: on) % -T ace ACE input for domain lookup % -T domain (dn) only look for objects of type domain % -T status (st) only look for domain status % -C charset specify character set for the input/output % Available charsets: US-ASCII, ISO-8859-1, UTF-8 (default) % % NOTE: Read the detailed documentation for valid argument combinations. There are two special queries % % [?, HELP, help] displays this text % alive at whois returns 'alive' if whois server runs properly % % Detailed documentation under https://www.denic.de/webwhois/?lang=en % Connection closed by foreign host. $ Notice that - unlike normal whois servers - this one apparently requires some other stuff, possibly including the text "whois", as part of the query. That may explain why a normal whois client gets an error, because the standard way to make a query is simply to send the string to query (eg, "uni-stuttgart.de" or "dunnington.cx"): $ whois -h whois.denic.de uni-stuttgart.de % Error: 55000000007 Request not clearly specified OK, so back to telnet, and try it with the syntax DENIC claims to want: $ telnet whois.denic.de 43 Trying 81.91.170.6... Connected to whois.denic.de. Escape character is '^]'. -T dn uni-stuttgart.de [lots of output] $ Aha! That works. But I can't replicate it with most whois clients. However, it /does/ work with the jwhois client, which some linux systems have, and which seems to have some special method to deal with DENIC. It doesn't work with the RIPE client - despite DENIC recommending that - unless you construct a rather odd-looking query by adding at least "--T dn": gleek:whois3-3.2.2 $ ./whois -h whois.denic.de uni-stuttgart.de Domain: uni-stuttgart.de Status: connect gleek:whois3-3.2.2 $ gleek:whois3-3.2.2 $ ./whois -h whois.denic.de --T dn uni-stuttgart.de [lots of output] gleek:whois3-3.2.2 $ So IMHO it's broken; it doesn't respond to a standard query format as defined in the RFCs, but only to a modified query string, one which some perfectly good clients can't correctly format. Just for comparison, I also tested the RIPE client, Microsoft client, and telnet with some .co.uk, .ac.uk, .com, .cn and .cx domains using several whois servers, and found a standard query worked every time. Obviously that's not exhaustive but so far whois.denic.de is the only one I've found with this odd behaviour. -- Pete Pete Turnbull From bulk at blit.ca Wed Mar 8 13:09:28 2017 From: bulk at blit.ca (bulk at blit.ca) Date: Wed, 08 Mar 2017 14:09:28 -0500 Subject: Looking to re-home some NeXT hardware In-Reply-To: References: Message-ID: <4330b2ab7c5beb0228a3bdb57d201632@blit.ca> On 2017-03-08 11:06, Tapley, Mark wrote: > On Mar 7, 2017, at 10:10 PM, Chris Reuter via cctalk > wrote: > >> >> I have some NeXT hardware that I'm looking to re-home.

It's been a long time since I had the Cube open so this is from memory. However, I'm reasonably sure that this was based off a NeXT card (whose name escapes me) that was half bus interface and half prototype board so that you could build one-off interfaces.

Now that is interesting! I concur completely, this does not look anything like my NeXTDimension. But it looks from the outside as though you have not one but two boards on the left side. My cube originally had only the board on the right of your picture (and in that same location). Unless there are internal connections between the two slots on the left side, you may have two Mystery Boards. Very neat!

Fwiw, Fujitsu Fi-4530 like I've got does 11x17" ADF or 11x17+" oversize (e.g. foldouts), it's fast, fairly compact, and weighs 18.7 lb. Recommended without hesitation for binders/documents.

I did a little research on that: The '-T' option is passed to the whois server, it's not a client option. Intelligent or modern clients know what options to pass to the appropriate server, in this case '-T dn' to the DENIC whois server. This option is completely legal and was introduced at DENIC in an attempt to better protect the domain holder's privacy (you know, different country, different rules). This was many years ago, but it's still there. RFC 3912 doesn't specify what output the whois server is supposed to send. Everybody "assumes" that it should be the complete domain information, but that's simply not the case. Imposing this assumption is what Mouse does, and that is wrong. Heck, I could even have a whois server that tells me the current weather forecast for a specific request ;-) It is a minimalistic directory service, nothing more.

So I wonder what replaced RFC 3912, and why there's a > mismatch between documentation and functionality. RFC 3912 is still the current RFC for whois; it's not been replaced. But there are two other related information systems, Rwhois (Referral whois, RFC1714, RFC2167) and whois++ (structured whois, RFC1835, RFC1913, RFC1914). They're more sophisticated, of course, but I don't know of any real-life examples and references I've found suggest they were never deployed. Rwhois runs on port 4321 by default and its syntax is nothing like that used by DENIC, while whois++ runs on port 63. Being an extension to provide structured responses to a range of template-based queries (it too can perform recursive queries on behalf of a client, like rwhois), its syntax also looks nothing like normal whois or that used by DENIC.

The software mentioned in the article sounds very interesting. It talks about starting with digital data streams from the 9 heads, but adds that you can start with analog data too.

NRZI is not self clocking if you consider an individual track in isolation. But it IS if you consider all the tracks at the same time, provided either (a) the data is recorded with odd parity, or (b) the all-zeroes data character isn't used. (a) is the case for 9-track tapes. 7 track tapes may be even parity, but that case seems to apply by convention only to text data (not binary data) and there, (b) applies. You do have to correct for track skew in this process, but that applies in any case even if you have an independent authoritative bit clock. It clearly can help to have tach signals as a way to improve bit framing, but I don't see that it's mandatory. paul From ard.p850ug1 at gmail.com Fri Mar 10 13:17:46 2017 From: ard.p850ug1 at gmail.com (Tony Duell) Date: Fri, 10 Mar 2017 19:17:46 +0000 Subject: HP 9815A In-Reply-To: <009f01d299c1$e51a4e50$af4eeaf0$@classiccmp.org> References: <009f01d299c1$e51a4e50$af4eeaf0$@classiccmp.org> Message-ID: On Fri, Mar 10, 2017 at 5:15 PM, Jay West via cctalk wrote: > Local electronics place has a HP 9815A for sale, the appearance from a 10 > foot distance was "fair" or slightly less than fair condition.

It is, IMHO the only HP desktop machine to be truely RPN. It has the 4 level stack with automatic lift/drop like the handhelds. The older HP desktops with the 3 level stack (9100, 9810) don't have automatic lift and drop so in my opinion are not true RPN machines. The other interesting aspect is that this is the only HP desktop calculator (as opposed to computer) to use a standard microprocessor. Earlier machines used a TTL-based bit-serial thing, slightlty later ones (HP9825, etc) used an HP custom processor. But the 9815 has a 6800 in it. -tony From cclist at sydex.com Fri Mar 10 13:25:23 2017 From: cclist at sydex.com (Chuck Guzis) Date: Fri, 10 Mar 2017 11:25:23 -0800 Subject: Tape reel data recovery from MERA-400 polish computer In-Reply-To: <67AC132D-6D57-40F2-963F-42E6A0C2C70A@comcast.net> References: <67AC132D-6D57-40F2-963F-42E6A0C2C70A@comcast.net> Message-ID: <7b5cdaeb-7f77-1e9f-29dc-762a1222c5b7@sydex.com> On 03/10/2017 10:58 AM, Paul Koning via cctalk wrote: > >> On Mar 10, 2017, at 1:39 PM, Al Kossow via cctalk >> wrote: >> >> >> The next extension is to track the tachometer values so that you >> can detect and compensate for tape stick/drag which is absolutely >> critical for formats that don't self-clock, like NRZI. > > NRZI is not self clocking if you consider an individual track in > isolation.

I think I mentioned that a couple of years ago. Even parity 7 track tapes were used on very old systems for reasons that escape me. One of the problems, then was how to represent an all-zero character, since there would be no transitions in that particular frame. A tach signal is useful for adjusting the width of the "window" when deskewing. I wonder if there's not a better way to attack the problem with some simple hardware. The original posters mentioned an AVR Arduino as their initial platform, but cheap SBCs are available that run much, much faster. Consider, for example, the RPi zero or the Orange Pi zero or a host other sub-$10 hosts running at a GHz or more. You'd need level-shifting for a modern MCU/CPU anyway, as logic levels are most commonly 3.3V, not 5V. --Chuck From echristopherson at gmail.com Fri Mar 10 13:34:21 2017 From: echristopherson at gmail.com (Eric Christopherson) Date: Fri, 10 Mar 2017 13:34:21 -0600 Subject: Vintage Computer stuff on EBAY.DE In-Reply-To: <985986916.2634209.1489130682505@mail.yahoo.com> References: <985986916.2634209.1489130682505.ref@mail.yahoo.com> <985986916.2634209.1489130682505@mail.yahoo.com> Message-ID: Hi, Martin.

One of > the problems, then was how to represent an all-zero character, since > there would be no transitions in that particular frame. Sure. One tape document I looked at mentions the use of odd parity on the 7-track tapes when writing binary data, even parity when writing "IBM BCD" character coded data, with one of the 6-bit values forbidden in that case (the value encoded on tape as 6 zero bits). A stretch with no transitions occurs of course at the block boundary (the gap). It also apparently occurs in other spots, for a few bit times: tape marks seem to consist of two frames separated by a few clocks worth of blank space. Ditto between data and block check frame(s), if I remember right. > A tach signal is useful for adjusting the width of the "window" when > deskewing. Yes, that was my point: useful to make the process easier or to improve the quality of the result if the inputs are marginal, but you can make it work without a tach signal. > I wonder if there's not a better way to attack the problem with some > simple hardware.

Al's mention of that Saleae device fits there: you could plug that into any suitable fast enough computer, and it deals with analog data so you can do the threshold in software.

Didn't understand the reason. - Also DD.MAC in the 5.0 - 5.4 and 5.7 changes often. I tested tu58fs with oversized TU58 tape for 5.3 and 5.7, the number of blocks is always patched into into offset 0x2c, 0x2d in DD.SYS - I made a working DD.SYS with .macro DD, .link DD, .rename DD.SAV DD.SYS Do you know how to make DDX.SYS?

I don't think Tor has suggested it's a client option, and I certainly did not. It's simply part of the string that one particular client knows to send to DENIC, and which at least one other client can be forced (manually) to send. > Intelligent or modern clients know what options to pass to the > appropriate server, in this case '-T dn' to the DENIC whois server. Well, for one value of modern :-) The RIPE client which DENIC themselves recommend people to use, does not do that. It has to be cajoled into sending the "-T dn" along with the query string. > This option is completely legal and was introduced at DENIC in an > attempt to better protect the domain holder's privacy (you know, > different country, different rules). This was many years ago, but it's > still there. Legal in what sense? It's not part of any RFC, and appears to be unique to DENIC. I regularly use dozens of whois servers and not one other honours, let alone requires, that option. Also not that RFC3912 gives a single protocol example which does not require any such option, and refers to RFC954 for normative references - ie, they way it should be done. No -T there either. > RFC 3912 doesn't specify what output the whois server is supposed to > send. Everybody "assumes" that it should be the complete domain > information, but that's simply not the case. That's certainly true. Very few whois servers return all the information; many won't disclose phone numbers, for example. In fact I was surprised how much text /is/ returned by DENIC. > Imposing this assumption is what Mouse does, and that is wrong.

No, that is not what I'm doing, though I can certainly see how you could come to that conclusion. I'm not expecting/requiring/whatever that the relevant WHOIS server return all available information. But there is a lot of room between that and returning no contact information whatever, which latter is what DENIC does when queried in the usual way, ie, just the domain name without any DENIC-specific text. And that's well on the "unreasonable" side of the line. In my opinion, of course. It's my mailserver, so that's what matters. >> This option is completely legal [...] > Legal in what sense? I make no claim about its legality, in either the RFC sense or the off-net-law sense (except that I believe I am within applicable off-net law). I simply consider it antisocial and uncivilized, and am not interested in accepting mail from any domain within its bailiwick. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From elson at pico-systems.com Fri Mar 10 20:42:32 2017 From: elson at pico-systems.com (Jon Elson) Date: Fri, 10 Mar 2017 20:42:32 -0600 Subject: Tape reel data recovery from MERA-400 polish computer In-Reply-To: <67AC132D-6D57-40F2-963F-42E6A0C2C70A@comcast.net> References: <67AC132D-6D57-40F2-963F-42E6A0C2C70A@comcast.net> Message-ID: <58C36418.8090707@pico-systems.com> On 03/10/2017 12:58 PM, Paul Koning via cctalk wrote: >> On Mar 10, 2017, at 1:39 PM, Al Kossow via cctalk wrote: >> >> >> The next extension is to track the tachometer values so that you can detect and compensate for tape stick/drag >> which is absolutely critical for formats that don't self-clock, like NRZI. > NRZI is not self clocking if you consider an individual track in isolation. But it IS if you consider all the tracks at the same time, provided either (a) the data is recorded with odd parity, or (b) the all-zeroes data character isn't used. (a) is the case for 9-track tapes. Yes, but the problem is 800 BPI is about the upper limit on density due to tape skew. I don't know for sure, but I strongly suspect that skew gets worse as the tape gets older. I've seen some tapes that were only a few years old where the skew got very bad. You could put a scope on the skew alignment test point and see the skew pattern pulsing as the supply reel rotated, meaning the tape got differentially stretched while sitting on the reel. But, glad they were so successful in their effort!

Ditto between data and block check frame(s), > if I remember right. The classic NRZI definition for 800 BPI 9-track is that there is a 2-character gap after the end of the user data block, then the CRC and LRCC characters follow. We had some tapes made on out IBM 360 that had little short gaps all over them, as they had the machine misconfigured and were exceeding memory bandwidth. The IBM could read them fine. I think they only detected the big gap to define the end of the record. Our DEC controllers all used the 2-character gap to detect where the block was ending. No way to fix that if the hardware tape control decided those gaps were the end of data.

Yes, several times though like Raymond says you may be stymied straight away if your adapter is using a fake FTDI chip. Neither of my adapters work with ADTPro largely because of the signals I think it's expecting to get with regard to hardware handshaking. Also they're using CH340/1 chips which are the Chinese FTDI clones. Recently I tried setting up a Raspberry Pi using a genuine FTDI USB breakout adapter that gives all handshake signals but couldn't get that to work either and resorted back to my old faithful XP desktop with real 16550 UART which works every time. My next idea was to get a BusPirate to see exactly what signals were in use on the real serial port but at the time BusPirates weren't available. Now I see they are again so I might have another look. -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

This is one of the things I will revisit. I'm still trying to compile programs on the vax that are designed to plot directly to a tek terminal connected to a serial port.

I can't run DecWindows on a MicroVax II with 11MB of memory, so I loaded the basic support files for DecWindows.

On the VAXstation II that I ran in college for one of the departments we would do TEK plots all the time. The programs that did them would send an escape sequence that would kick the normally VT100-ish terminal emulator on screen into Tektronics 401x emulation and then send the sequence of tektronics escape sequences to do the plot. We'd then take a screen shot of the plot if we needed to print it quickly (but at low quality) on the laser printer, or we'd fire up the Tektronics Plotter and redirect the output there if we were doing photo-ready for a conference or paper. This was all on VMS 5.4 running DISSPLA... We did have 16MB of memory, though.... Warner From blstuart at bellsouth.net Sat Mar 11 12:43:27 2017 From: blstuart at bellsouth.net (Brian L.

There are two things that come to mind as possibilities. First, if xterm isn't getting switched into Tek mode, who knows what you'll see displayed. To force it into Tek mode, start it with the -t option or in a vt100 xterm window do a ctrl-middle click and you'll get a menu where you can select "Switch to Tek Mode." The other possibility is that depending on setting, kermit might not be 8-bit clean. IIRC the Tek escape codes need the terminal line to be in 8-bit mode. When I'm connecting to a device speaking the Tek escape codes, I usually use cu instead, and it's generally worked pretty well for me.

I've had difficulties with USB to RS232 adapters in the past, which is why I bought it from the ADTPro website. I figured that it would be more likely to work straight away. When I stare at device manager and pull out the cable. nothing happens. If I scan for hardware changes, the system still sees "unknown device" and "base system device" and tries again to find drivers for them. Device manager is showing an installed USB to serial adapter, but these others won't go away. On a venture to the grocery store today, I stopped in at a Radioshack which was having a liquidation sale. I bought their "Gigaware" USB to serial cable for a decent discount at $20. As I understand it, this one uses a Prolific chipset which can occasionally be troublesome.. Thankfully, there appear to be drivers for it specifically for Windows 7. I'll give it a shot and report back. Thanks for your're assistance!

That's the chipset name I was trying to remember earlier.

The KA630, the MicroVAX-II CPU board (which includes the console serial port), has a relatively limited serial port. For example, it has only a byte or two of buffering in each direction, it cannot be used directly from userland even if the kernel wants to let it (it is accessed with MFPR and MTPR instructions), it has no software baudrate control, and various other limitations. These have concomitant benefits for console use, such as no software setup being required to get small numbers of characters transferred. But they do rather cripple it for voluminous data transfer. If you have an at-least-mildly-smart serial port card (eg, with substantial hardware buffering capability, and/or with DMA capability), you will probably get better performance with it. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From dj.taylor4 at comcast.net Sat Mar 11 19:19:36 2017 From: dj.taylor4 at comcast.net (Douglas Taylor) Date: Sat, 11 Mar 2017 20:19:36 -0500 Subject: Tektronix Terminal Emulation In-Reply-To: <01QBV3TJJQBC002QSL@beyondthepale.ie> References: <71dcab3b-4be8-5cb9-d1f4-78903be1a400@comcast.net> <71d7b48e-1e4a-9f3f-60fb-bfd8c9c1e325@comcast.net> <01QBV3TJJQBC002QSL@beyondthepale.ie> Message-ID: <6407e82d-866b-de53-29de-98bcb18b0939@comcast.net> On 3/11/2017 4:11 PM, Peter Coghlan via cctalk wrote: >> >> I can't run DecWindows on a MicroVax II with 11MB of memory, so I >> loaded >> the basic support files for DecWindows. > > Are you sure? > > I can run the old XUI DecWindows on VMS 5.5-2 (the newest VMS that > will support > XUI) in monochrome on a VaxStation 2000 with just 6MB.

Just to bring some closure to this thread, I had some time this evening to get everything hooked up: A PDP-11/34 connected to an SB11 QBus chassis via a DW11-B. And I've successfully booted XXDP and Ultrix-11 from a CMD CQD-200 SCSI controller installed in the SB11. Seems to work perfectly.

It was 8-bit clean. And did allow for connection of a printer to it, though a relatively simple one. We wound up in the end, though, not using it except in a pinch. The limitations were just a bit too much to give reliable behavior for anything other than having a DECwriter II or VT220 connected to it. We had a 4-port serial card to connect the plotter, and a few other specialty devices we needed for our VaxStation II (which had the same KA630 CPU board and a graphics board).

TU58? They're hard to come by, but the good news is you can *emulate* them with a PC and a serial port (or USB adapter). That's how I run XXDP on most of my systems, and pretty much all of the systems I check out for people. You've got a DLV11-J in there so you've already got SLU0 in place (or can strap it up for it). AK6DN has a bunch of useful TU58 images premade, with listings of what XXDP utilities are on them. It's also possible to boot other OSes on TU58, like RT-11. There's even a patched RT-11 driver to fudge the capacity on TU58s so you can use the emulator(s) to store a much larger volume of data. Helps to set SLU0 for a higher speed than 9600 if you plan on doing that :) Thanks, Jonathan From starbase89 at gmail.com Sun Mar 12 15:57:54 2017 From: starbase89 at gmail.com (Joe Giliberti) Date: Sun, 12 Mar 2017 16:57:54 -0400 Subject: help needed installing USB to Serial Cable for ADTPro In-Reply-To: References: Message-ID: The bootstrapping option is grayed out in ADT so I can't do that.

While not a COPYRIGHT issue, it is possible, and not unlikely, that they were considered to be part of the course work, and that those taking the course may have agreed, explicitly or implicitly, not to pass them on.

Resell: sure. The copyright interest of the seller is extinguished when you purchase them by whatever means absent an explicit agreement to the contrary. Copy and upload the copy: No. Copyright Law would preclude that absent permission from the current owner of the copyright. Copy for yourself and then sell: Legal grey area, most likely not legal, but kinda depends on your local jurisdiction. Copy and upload to bitkeepers: Possibly the most beneficial thing you could do. Likely not a lawful copy, thought (see above).

These materials were apparently never available except by enrolling in the course. Sure, such an agreement would have to exit, but not necessarily attached to the course workbook. It could exist as part of the documents that the participant signed to REGISTER for the course. And, as the appellate court ruled in ProCD V Zeidenberg, it does not have to be in writing, nor signed, so long as it is known AT THE TIME that the agreement was reached. (not necessarily NOW!) There is no problem with selling the sole copy in terms of COPYRIGHT law. Your comments are entirely about the copyright law. Which is not the issue to be concerned about in this case. The worse problem here is whether the previous owner entered into a licence agreement as part of registering for the course. I have run into such license agreements in registering for commercial courses. ("all materials used in the course . . . ") Not seeing a license agreement attached to the materials is sufficient to show that you had no willful intent to violate it, and that should be enough to sell them, in good faith. But it doesn't mean that it doesn't exist. (Certainly having a work with the title/verso (copyright) page torn out is not the same as it never having had one, of course, but the license agreement need never have been physically attached) Remember that ProCD V Zeidenberg was about material that is presumably not even copyrightable! but the courts upheld a violation of license, on a shrink-wrap license! It was a LICENSE lawsuit, not a copyright one, although that was also alleged. http://www.freibrun.com/not-fast-appeals-court-reverses-upholds-shrink-wrap-agreement/ Zeidenberg bought a retail "single user" copy (not even the multi-user version) of a CD-ROM telephone directory. He then created a website selling access to the content from it. The appellate court explicitly ruled that ProCD did NOT have to print the license agreement on the outside of the box. The licensee does NOT need to sign! "A contract for sale of goods may be made in any manner sufficient to show agreement, including conduct by both parties which recognizes the existence of such a contract." (about EXACTLY that.) (such as the documents regietering for the course!) Zeidenberg DID click the "I accept" box. If there WAS a license agreement, then it was abject stupidity for the licensor of these materials not to embed that information on the item! Personally, I feel that the court gave far too much power to adhesion contracts!

Again, that's an explicit, in writing modification of the normal terms of copyright. Click through licensing has been, I must note, non uniformly enforced. > Personally, I feel that the court gave far too much power to adhesion > contracts! Yea. It certainly sounds like it, but I've not looked into the particulars of that case to know for sure. One of the tenants of the ProCD case is that the terms must be commercially reasonable and not otherwise unconscionable which gives a lot of wiggle room for a good lawyer. Absent seeing any agreement, it's hard to know what the terms are. And if a number of years have passed since the original material was distributed, it can be difficult to prove that the person making the sale has an obligation to follow the original license if it wasn't provided upon a sale contrary to the original license. It also depends where you are located (China doesn't enforce click through licenses, for example). So there's lots of "yea butt's" here and the specifics of the original company and License matter a lot. Absent those, it's quite difficult to know what applies here. Maybe there was a license. Maybe the licensor still cares. Maybe they can prove it in court. Maybe a simple sale would trigger a case. Maybe not. It's all about how much risk you are willing to assume in the absence of concrete, verifiable information as to whether you proceed with the sale....

I am currently up on IBM and I'd find it odd if there were not clear notices in any class document with IBM copyrights, dates, etc. Also if the strings mentioned at length in the other answer thread exist, and IBM had anything to do with this (as in they own AIX), the owner of the course usually publishes such notices clearly as well. Not absolutely, but every document since IBM lost the copyrights on MVX and the like is pretty well done right by their legal department. Maybe some scans or snaps of the front part of the document of such notices we can help more if it isn't clear with what they put there. thanks jim From barythrin at gmail.com Sun Mar 12 23:53:53 2017 From: barythrin at gmail.com (Sam O'nella) Date: Sun, 12 Mar 2017 23:53:53 -0500 Subject: AIX documentation Message-ID: <34i2481uc2v735drdbsbwfe3.1489380833181@email.android.com> As others said, we're not lawyers so ymmv but I would take it as the same as selling a used cd, dvd, software or books.

They're hard to come by, but the good news is you can *emulate* them with a PC and a serial port (or USB adapter). That's how I run XXDP on most of my systems, and pretty much all of the systems I check out for people. You've got a DLV11-J in there so you've already got SLU0 in place (or can strap it up for it). AK6DN has a bunch of useful TU58 images premade, with listings of what XXDP utilities are on them. What makes them hard to come by is that they must be preformatted for the TU58, as far as I know only DEC had hardware to do that. The Drive as it stands cannot do that, It is not capable of higher storage capacity as a result (hardware limit, programming and no formatting). > It's also possible to boot other OSes on TU58, like RT-11. There's even a patched RT-11 driver to fudge the capacity on TU58s so you can use the emulator(s) to store a much larger volume of data. Helps to set SLU0 for a higher speed than 9600 if you plan on doing that :) I run RT-11XM using TU58 a real one. Boot times to load the RT-11XM: driver and copy the tape and boot to XM: virtual disk that takes about 5 minutes. That's with the files optimally placed on the tape (in order of need) to limit the number of rewinds. The VAX750 used TU58 to load microcode and diagnostics. Any os that can fit on the 256K per tape times two tapes would likely be bootable if it can do the serial protocal used for the booter and the OS. A PC emulation (or Rpi) can do this a bit faster (just over a minute for a boot can copy to VM:) but you are limited to the max baud rate (38K) of the serial port use by the DD driver. There was at least one company that used a floppy drive (360K 5.25 or 720K for two sided) with a TU58 emulation that was somewhat faster than tape due to faster seeks to a block.

Speak for yourself; my comments below are the legal position as best I know it, and not influenced in any direction. Of course, as are most people here, I am not a lawyer (although I've spent enough money on Intellectual Property lawyers over the years to send myself to law school, had I had the time, so I now know a little bit about the subject :-), and my perception is that the lack of knowledge on all our parts implicit in that is a far larger risk than any bias. > From: Warner Losh > Resell: sure. The copyright interest of the seller is extinguished when > you purchase them I don't think that's correct: any copyright rights held by any party are generally not, AFAIK, modified by sale of the material from a second party (i.e. not a rights holder), to a third (you). But that's immaterial, as long as one is only selling a copy which one purchased. As long as that copy was itself not produced in violation of a copyright, transfer to a fourth party (whoever you sell it to) is entirely legal. (Just like selling used books - which generally are in copyright - is legal.) You are (I'm pretty certain) not in any danger on copyright grounds, as long as you don't make any copies yourself. (What the situation is, if that copy _was_ produced in violation of a copyright, I am not sure of.) Restricted rights (such as a duty not to pass the material along) are probably not an issue, as that is entirely a civil contract between the issuer and the second party (above) who purchased them. If that party elects to sell the items _without_ making a second civil contract with the third party (you), those restrictions would not apply. For the second party's violation, the only recourse of the first party would be to sue the second party. Since the third party doesn't have a contract with anyone, there are no grounds for any claim against them. If there are trade secrets involved, I'm not 100% sure of the situation, since there are some protections for trade secrets in the law; but those mostly apply to deliberate theft or espionage. My suspicion is that if a third party gains access to trade secrets through negligence on the part of the second party - i.e. the second party giving/selling material containing trade secrets to a third party - the third party is clear to do what they want with the information. But maybe not, I just don't know enough about protection of trade secrets. The final area to be considered is theft. If the party from whom the documents were obtained did not rightfully own them (e.g. if they technically still belong to the first party, and they were merely on loan to the second party), then the third party (you) can't own them either, and so you (legally) can't sell them. Having said all that, it would probably cost more to ascertain their exact status (were they sold or loaned, etc) than they are worth (unless they are worth a goodly amount). But I also suspect that the rights holder(s) probably no longer care - but that's just a guess.

Prefer collection, but will ship small stuff at your *own risk and cost*. I will ship small items outside Europe but the large stuff is UK/EU only due to likely power supply restrictions and excess shipping costs. Unless otherwise explicitly stated, all items are **untested**. I will test computers on demand if needed. Cards and CPUs I can't really be bothered to. No returns, folks, ya gets what ya gets.

One of the systems is an Ardent Titan, which to my knowledge was the first (mini-) supercomputer to come with an integrated high-end graphics subsystem (1280x1024 at 60Hz, hardware spheres, antialiasing, and cast shadows). After careful checking, I powered it on yesterday, and got as far as trying to boot it; unfortunately, the harddisk does not contain the OS, but I'm trying to get access to an installation tape. There's a full writeup about my efforts this weekend on my website: http://www.vaxbarn.com/index.php/42-repair/576-ardent-titan-power-on A description with some pictures of the Ardent can be found here: http://www.vaxbarn.com/index.php/other-bits/565-ardent-titan Uncrating pictures are here: http://www.vaxbarn.com/index.php/41-acquisitions/575-supercomputers-have-ar rived Anyone who knows anything about these machines, please contact me! Also, if you have access to installation tapes, manuals, brochures, anything related to these systems, please let me know.

I have old copies of OS that have been opened and prob registered somewhere, like old Sun and Solaris. Even Microsoft stuff was never a problem, although I would not go so far as to pull license stickers off recycled computers. Never got in trouble for selling those. So I doubt there will be a problem over these, since they do not deal specifically with security or anything. A 26 year old manual is not going to excite anyone too much.

IT the system expects to be able to rewrite some locatons then you need EEPROM. If the system expects to be able to rewrite blocks then it s flash. If you put a Eprom in you can do none of those things without a UVlamp and an external programmer(most cases). The P112 can use all or any save for being in system writable if needed.

But for the group...) Assuming there isn't a hardware issue like the null modem being plugged into the wrong DIN5 socket on the IIc, my guess is there's a bit-width issue with Java. First, some background: it sounds like you've been hacking around with (the location of) the RXTX serial library, which should not at all be necessary; it should be left where it is after unzipping the ADTPro distribution. Also, it's unusual for Windows not to recognize the FTDI-based chip in your UGREEN adapter; it should be automatically downloaded and installed. You should not need to install it manually. You should see the COM port populate in the Windows hardware manager when you plug it in (and the device driver is correctly installed). You said your Windows was version 7, 64-bit. Let's check Java. Go to a command line, and run 'java -version'. The build identifier will let us know if it's 32- or 64-bit. If it doesn't match your OS, that's the reason why ADTPro can't see the serial port (through RXTX). - David From steve at oldcomputers.net Mon Mar 13 14:10:14 2017 From: steve at oldcomputers.net (Oldcomputers) Date: Mon, 13 Mar 2017 12:10:14 -0700 Subject: Fwd: Looking for Apollo Workstations for TV show References: Message-ID: Get your systems on TV!

Granted the PC currently in use is a 32bit XP machine so I could make sure everything was working on a real 16550 UART before going over to the USB adapter but I'll try a win 7 64bit machine when I get the chance. My adapter is a clone one with the CH340 chipset used and abused on arduino clones so I already had the driver package, it was discovered as COM4. Fire up ADTPro via the .bat file, go to serial setup to make sure COM4 is selected along with '//c with imagewriter cable' then plug in the //c and boot to the ] prompt followed by: IN#2 14B On the PC go to 'bootstrapping -> ProDOS -> speediboot' and hit OK...up she comes.

(My answer to the latter question, BTW, is 'Yes.') Thank you. We don't agree on all the details, but it's a worthwhile discussion when kept factually accurate. For example, there is no lack of copyright in "abandonware", but it is true that some things will not be pursued. She should definitely sell them. On THAT, we all agree. Whether that is completely legal is unclear, but on a 26 year old manual, the likelihood of repercussions is miniscule. It turns out that they are NOT materials created by the people giving the courses, but instead are [excerpted?] photocopies of manuals put out by IBM. Therefore, license issues are rather unlikely.

The key fits snug on a plastic white pin, shaped as a ?+?. Over the plastic pin is a small spring. If the spring is not installed, the pin will simply ?fall down? due to gravity, causing a continuous ?key pressed? signal. You can (gently) pull the key cap. If the pin does not ?fall down?, you have the reason why it is hard to use: dirt or dust.

Sure. It might be cleanable. VT52 keys are crossed wedges, gold plated, with the key pluger in between which moves out of the way when you push the key. They were incredibly reliable. > 1.

On the VT52s/VT55 that I've worked on... It's actually not a separate switch. There's an single moulded frame for the entire keyboard. Each swtich constists of a pair of contacts which naturally touch, a return spring and a plunger that keeps the contacts apart when the key is not pressed. You can pull off the keycap. Often carefully cleaning the contacts (which are then visible) will help. The plunger and spring pull out too, officially you are not supposed to re-use the plunger but you have to now. The contacts can be desoldered from the track side of the board and pulled out. There was a special tool to put them back without damaging them, it is possible (but tricky) to do it with long-nosed pliers. Avoid removing the contacts unless you really have to replace them with ones from another key or keyboard. It's the same type of contact mechanism as in the early TRS-80 Model 1 and the HP85. The technical reference / service manuals for these 2 machines may be of interest. -tony From paulkoning at comcast.net Tue Mar 14 08:20:48 2017 From: paulkoning at comcast.net (Paul Koning) Date: Tue, 14 Mar 2017 09:20:48 -0400 Subject: VT52 keyboard question In-Reply-To: References: Message-ID: <9548185C-E0F3-4CB7-8CA2-0759DE60BB81@comcast.net> > On Mar 13, 2017, at 5:07 PM, Henk Gooijen via cctalk wrote: > > ... > My guess is that the VT52, VT55, VT05 and LA30 are identical. No, fortunately not. The LA30 was notorious for having a very bad and very unreliable keyboard. Some GT40s had that same keyboard as well, I don't remember if that changed later. The keycap shapes were different too: larger and more square with sharper corners. I don't remember the VT05 well enough, it may have been like the LA30 or different yet again. The VT52 keyboard technology shows up in other VT variants of the same family: VT55, VT61/t, VT62. It is also used in the LA36. Similarly, VT100 style keyboards show up in other devices of that era: Gigi for example. And the LA120 may use that generation of switches, I don't remember anymore. paul From dkelvey at hotmail.com Tue Mar 14 11:25:20 2017 From: dkelvey at hotmail.com (dwight) Date: Tue, 14 Mar 2017 16:25:20 +0000 Subject: sourcing Atmel 29Cxxx series flash roms In-Reply-To: <7a13e80a-5595-825b-81f3-b0ea55c12f62@verizon.net> References: <58C6CB5A.5020303@pico-systems.com>, <7a13e80a-5595-825b-81f3-b0ea55c12f62@verizon.net> Message-ID: What about the package?

The LA30 was notorious for having a very bad and very unreliable keyboard. Some GT40s had that same keyboard as well, I don't remember if that changed later. The keycap shapes were different too: larger and more square with sharper corners. I know that back in the day, we had about a dozen VT52 and 3 VT50's. They were the same keyboard, but with different internal circuit boards (we had a few former VT50's that were upgraded to VT52's, at least according to the techs that I worked with at the time). I still remember having to edit my FORTRAN code for a while on a UPPERCASE ONLY terminal until I got enough seniority to warrant moving up a dual-case terminal.... thankfully these were all replaced by VT100s over the years I worked there and my role shifted a bit to needing a VT100 to support a customer that had an application that used the advanced features of the VT100: double size characters, line drawing boxes, etc. Man, that was a million years ago...

Sufficient hardware documentation has been available to write emulators (Previous) and port NetBSD. That said, I don?t understand why one would have NeXT hardware and then run NetBSD on it instead of the NEXTSTEP/OPENSTEP operating system that was designed for it and is period-appropriate. If you?re not going to use it as NeXT hardware, maybe someone who will use it that way would be happy to have it. Also, especially for software that?s (1) built using a common and well-undertsood architecture, (2) not ?secured? in any way, and (3) not being updated, you really can maintain and improve it yourself pretty reasonably. Heck, there?s a pretty accurate Open Source decompiler for Objective-C called ?code-dump? (derived Steve Nygard?s ?class-dump?) to which it would probably be straightforward to add 68040 support? -- Chris From cmhanson at eschatologist.net Tue Mar 14 14:08:42 2017 From: cmhanson at eschatologist.net (Chris Hanson) Date: Tue, 14 Mar 2017 12:08:42 -0700 Subject: Looking to re-home some NeXT hardware In-Reply-To: References: Message-ID: On Mar 12, 2017, at 7:26 PM, Ed via cctalk wrote: > > OK anyone else have a cube out there that is cosmetically decent? does > not need to be internally complete? > > Ours is a bit of a beater for the display What?s wrong with yours that you can?t clean it up for a non-operational display? -- Chirs From jnc at mercury.lcs.mit.edu Tue Mar 14 14:11:17 2017 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Tue, 14 Mar 2017 15:11:17 -0400 (EDT) Subject: Pair of Twiggys Message-ID: <20170314191117.D8ED118C07A@mercury.lcs.mit.edu> > From: Zane Healy > Good grief!

Yes, of course: nobody had thought of a cheap personal computer before him. (Which reminds me, does the CHM have a Datapoint 2200? If not, we really out to try to round one up for them.) Or even a personal computer. (Ditto for the LINC.) Although I suppose you might have been talking about the software. I mean, without that whole display/windows/menu/mouse thing he invented, to allow ordinary people to use a computer, where would we be? Look, I fully admit that Steve Jobs was a _very_ sharp person who had a _tremendous_ influence. (Every time I hear someone saying marketing people are useless - first up against the wall, etc - I reply 'No, only bad ones - which is a lot of them. The very best ones, like Steve Jobs, are worth their weight in triple-refined iridium. A _good_ marketing person can tell you what customers _want_. A _truly great_ one can tell you what they _need_, but don't yet even realize they do.') However, the people (and there are quite a few of them) who have gone way off the deep edge, and have turned him (and Apple) into some sort of overblown cult, just don't have a balanced perspective. There are plenty of people out there who deserve at least as much credit for the information society we now live in, who are almost totally unknown to the population at large; starting (probably) with Licklider.

On the other hand, Steve Jobs wasn't really just a marketing wizard ? he was a visionary, although some of his visions were less than great. He was also a stickler for perfection and largely unwilling to make compromises. So, Steve Jobs may not have invented the personal computer, or graphical user interfaces, but he should get some of the credit for the fact that we're not all running Windows on variations of crappy PC hardware.

I know the Knight TV system at the AI Lab was a very early bit-mapped display, but I don't know where the idea first appeared. (There were of course influential earlier display systems, such as the one on SAGE, althoug those were of course all stroke-based systems, given the limited memory of the period.) Windows and menus are AFAIK from PARC, but maybe there are antecedents I don't know of. > Bah, he was an ego-driven trinket salesman.

I know the Knight TV system at the AI Lab was a very early bit-mapped display, but I don't know where the idea first appeared. (There were of course influential earlier display systems, such as the one on SAGE, althoug those were of course all stroke-based systems, given the limited memory of the period.) Windows and menus are AFAIK from PARC, but maybe there are antecedents I don't know of. > Bah, he was an ego-driven trinket salesman.

Mercury dissolves lots of metals (iron is one exception), forming alloys called amalgams.

Lots of folks are creating digital negatives. I don?t know if you can even get paper for a stabilization processor, not to mention I doubt it would work for me. My main enlarger (currently the only usable one) is a old Beseler 45. I spent a day last summer getting it working better. My latest score was two Jobo CPE2 processors in the last month. Between the two, I only need one more tank (and technically I don?t need it). I can now do daylight rotary processing of anything from 35mm to 11x14 (I can currently shoot up to 8x10). So far I?ve only used it to process 8x10 sheet film. One of my next projects needs to be to get a proper darkroom setup, so that I can heat it, or cool it. That way I can work year around. Ideally it would include room for things like drum scanners and LF printers, but that?s dreaming. :-) Zane From vintagecomputer at bettercomputing.net Tue Mar 14 18:53:53 2017 From: vintagecomputer at bettercomputing.net (Brad H) Date: Tue, 14 Mar 2017 16:53:53 -0700 Subject: Pair of Twiggys In-Reply-To: References: Message-ID: <059f01d29d1e$3dd8e510$b98aaf30$@bettercomputing.net> I'm assuming anything can be interfaced to old tech.

A lot depends on whether you want to make replicas, or compatible. Jobs wanted a closed system with significantly increased difficulty for after-market supply of common items. The bizarre Twiggy drive system did not provide improvement over 96tpi double density ("quad") standard systems. A long time ago, Eric Smith explained to me the details about them (he could probably build one): 1) track to track spacing is 62.5? tracks per inch, as opposed to the "standard" 48tpi or 96tpi (or less common 100tpi (Micropois)) That should not be very hard to do, but not trivial. 2) They used variable rotation speed, from 200RPM? to 350RPM?, to make less variation in the FCPI (flus changes per inch) Relatively trivial, for a drive to be used on something other than the original Lisa, as the rotational speed could be left constant, and vary the data transfer rate. 3) Instead of a "normal" pair of facing heads, they wanted to keep single sided heads, with their felt pressure pads, so they went with that strange double slot, providing unmatched opportunities for always leaving a thumbprint on the media. That could be easily worked around, by simply using conventional double sided head, and maybe, in some cases, losing half a revolution waiting for the desired sector to come around. Very few pieces of software (copy protection) rely on the relative timing of the two sides. Since the Twiggy heads are connected to the same mechanism, but on opposite sides of the spindle, when one head is hubward, the other one is rimward, so for most purposes, switching to a conventional head system would provide improvements in speed. The optimum speed method for reading a Lisa Twiggy would be to stick with one side, reading all tracks, and then when at the last track, the other head would be in position to read the first track of that side. That is not the same as what we have become accustomed to, where after reading one track, switch to the other head, and read that track of the other side, and then step to get to the next two tracks. 4) GCR. I don't know the specific GCR pattern used, but that information is out there, or can be empirically determined. 5a) There is an extra hole, for latching the disk in place? or for later plans for a disk changer? 5b) Notch out of one corner to avoid ibverted insertion. 5c) Write protect/enable notch is in a different position. Trivial. (I was amazed that on the "Computer Bowl" quiz show, nobody on Bill Gates' team could remember where the write protect notch on an 8" disk was!) Total capacity was 850K? Media appears to be 600 Oersted (same as 1.2M) You will not be able to use a Western Digital/IBM style of disk controller, due to the GCR, non-WD/IBM sector headers, and maybe the variable speed. BUT, if you manage the track spacing, then it should be possible to read them with a flux transition board, such as Kryoflux. Or, design and build a suitable logic board. There are a couple of ways to manage the track spacing, ranging from analog positioner (Amlyn), extremely crude milling a new "record" for an SA390/SA400, different diameter winding hub for split band positioner, gearing interposed between stepper and positioner, different stepper motor, etc. I know none of the details for doing those, but it does not seem insurmountable. Judging by the eBay response, it looks like a replica (or counterfeit?) would be far more valuable than a usable substitute.

I keep waiting to see how much a Macintosh version of the Twiggy would sell for.

Xerox got pre-IPO Apple stock in exchange for the PARC visits and the chance to use and build on what they saw. 2. What the Apple folks saw and what was implemented for Lisa and then Macintosh were vastly different. Just a few examples: - Overlapping windows that update even when partially obscured. - The top-of-screen menu bar. - The one-button mouse. - Open & save dialog boxes. A lot of research and development went into the Lisa and Macintosh interfaces. They weren?t just ?copied from Xerox.? If you sit someone who knows how to use a Mac in front of a circa-1979 Xerox Alto, they?ll be pretty mystified.

I had one of these in my office for a few months, after their demo in Houston we were in constant contact to promote and sell them. Ardent, later Stardent supplied the hardware and we ported an application to show at the Offshore Technology Conference, in our booth. Great guys, and it got a lot of interest - it was a 3D model of downhole pipe exhibiting corrosion, 100K rendered polygons and you could swing it around in realtime, very impressive hardware for the 80's. I have maintained my interest, they dissolved in spite of a very impressive machine. The visualization pipeline was spun off as a separate company, AVS. Kubota (who purchased Stardent) put the rendering software, Dore' in the public domain. I have built it here under FreeBSD on a PC; it was in the ports system for a while, and without to much messing with, I got the demos running (FLAG, a flag blowing in the wind, with controls for wind speed and direction, controlled by the knob box) are still impressive. Let me know how you come along, I really want to see you bring this up. I can certainly copy Dore' over to you. Another great resource, is the story of the machine itself.

One of the systems is an Ardent Titan, which to my knowledge was the first (mini-) supercomputer to come with an integrated high-end graphics subsystem (1280x1024 at 60Hz, hardware spheres, antialiasing, and cast shadows). After careful checking, I powered it on yesterday, and got as far as trying to boot it; unfortunately, the harddisk does not contain the OS, but I'm trying to get access to an installation tape.

This would >be a first for me, I have EPROMs from the seventies which are still fine. I caused (I have people working for me who are really good at this) the 8748 to be removed from the one PCB. Reading it in my Expro gives me sort-of random results. Looks like some bits are high, some are low, and some float all over the place. No two reads return the same data, but some bytes are constant over two or three reads and other bytes are constant over two or three other reads. Is this the way an EPROM would fail? Seems reasonable to me. Anyway, I guess I'm SOL unless I can find a working drive. As far as I can tell these were used in the Heath / Zenith 170/170 luggables, also in the Morrow Pivot maybe. Tony would probably just rewrite the firmware. It's only 1024 bytes, how hard can it be? :-) Seriously, I am thinking of reading each byte say 100 times, averaging that, and then sticking the whole thing through a disassembler. But it seems a bit of a mammoth task.

Absolutely; and that's a large part of the reason for the success of Apple. His products were just really well done. It's also, I think, a big part of the causality for another Apple characteristic: their push for closed systems. The thing is that Steve wanted to make the user experience as good as possible (another hallmark of Apple stuff) - and when the 'system' includes pieces being independently sourced from multiple entities, it's hard to make that happen - there will be glitches, etc. So that's why he usually wanted to bring the entire thing inside the Apple envelope. > So, Steve Jobs ... should get some of the credit for the fact that > we're not all running Windows on variations of crappy PC hardware. I think that's not accurate; Linux may not have a large user base among non-technical people in the laptop area, but it does show that there are other alternatives.

I don't agree with the "vastly". (Having said that, I salute the Lisa/Mac people for doing a very good job of producing a excellent user interface.) The changes in the interface (menu bar, etc) are not that large; they are mostly minor refinements to the basic image/pointing-based interface pioneered by Xerox. The biggest improvement, IMO, was not in the details of the window system, but that everything used a common user interface - and the lack of that on the Alto was not planned, but more a result of the fact that the Alto was so far into new territory, and not done as an integrated system, but as a platform for research. > - The one-button mouse. Err, some of us don't see that as an 'improvement'... :-) > If you sit someone who knows how to use a Mac in front of a circa-1979 > Xerox Alto, they'll be pretty mystified. Yeah, but that's in good part because the Alto user interface is such a dog's breakfast - Draw is nothing like Bravo is nothing like etc, etc. But, like I said, that was inevitable, given the process that produced the Alto.

The Programma 101 indeed used a delay line. Such delay lines use magnetostrictive means to push a torque pulse into one end of the wire, as well as detect a torque twist at the other end of the wire. Magnetostrictive materials are typically a metal alloy that lengthens or shortens depending on the polarity of an external magnetic field, and will also generate a small magnetic field if stretched or compressed. In a magnetostrictive delay line thin strips of magnetostrictive metal are attached to opposite points tangential to the circumference of the end of a nickel-alloy(typically) wire. These strips, for whatever reason, are typically called "tapes". Each tape has a small coil of magnet wire surrounding it, wound oppositely around each tape, such that when a short current pulse is sent into the coils, one tape momentarily lengthens, and the other tape contracts, causing a slight but sharp twisting torque to be applied to the wire. This acts to transmit a pulse of energy into the wire. The torque twist mechanically travels through the wire to the other end, where it causes one tape to lengthen slightly, and the other to compress slightly, which induces a small current pulse into the coils around the tapes, which can be amplified to match the electrical characteristics of the original pulse. Sending a current pulse through the coils in one direction causes the twist to occur clockwise, and the pulse going the other direction induces a counter-clockwise twist, allowing ones and zeros to be pushed into the wire as clockwise or counter-clockwise torque twists. The amount of time that elapses (delay) from the pulse being injected to being received at the other end of the wire is based on the metallurgy of the wire, and its length. The wire is capable of remembering some number of torque twists as bits, with a clockwise torque, for example, representing a one, and a counter-clockwise twist representing a zero. The wire was typically arranged in a spiral inside a metal housing. Silicone or rubber supports supported the wire without attenuating the torque pulses in the wire. In some cases, there were "taps" along the length of the wire that used the same transducer method to pick off bits at different delay periods. The use of such delay line technology in calculators arose out of the need to store a moderate number of bits to represent the working registers of the calculator. At the time, magnetic core memory was still quite expensive, integrated circuit technology was in its infancy and too expensive to use for mass storage in a calculator, and it was generally cost and size prohibitive to store the bits required in discrete transistor flip flop storage registers (though a few very early electronic calculators did use this method). Given that delay line technology had been used with success on computers (though the Univac I delay lines were very different than magnetostrictive delay lines), they were a low cost, relatively simple way to provide the small amount of storage required for an electronic calculator. A prime example of the use of magnetostrictive delay lines in a computer was the Packard Bell 250, a low-cost "personal" computer introduced in the early 1960's. The bit-serial nature of the delay line was ideal for a calculator, since a bit serial architecture is coincident with the most efficient way to make an electronic calculator, where raw speed is not a requirement, and minimizing the component count saves money. The serial nature of the delay line means that if a specific bit is needed, the logic must wait around for the bit to arrive at the end of the delay line. This slows down the operation of the device, but in the case of a calculator, where results are subject to human perception, 10s to 100's of milliseconds is well within the acceptable time for a calculation to occur. > I forget what the Dielh Combitron used but I know it used a two delay lines. One was for registers and the other was for lookup tables that loaded at turn on time from a metal tape ( as I recall ). The Diehl Combitron did use two separate delay lines, one for the registers(as well as learn-mode program storage) as mentioned, but the other one wasn't really for lookup tables, but instead stored the operating microcode that made the machine run. The microcode was indeed loaded from a punched metal tape at power-on time. The ingenious design of the Combitron was done by Dr. Stanley Frankel, a nuclear physicist who was deeply involved in the mathematical modeling that made the atom and hydrogen bombs possible. After the Manhattan project ended, he was involved in the design of quite a few computers and calculators. Notable computers that he designed were the Librascope-General Precision LGP-30, the aforementioned Packard Bell 250, and some design work on early General Electric computers. He also designed the Smith Corona/Marchant Cogito 240 (and follow-on Cogito 240SR) electronic calculator, as well as the Diehl Combitron. Many calculator companies used magnetostrictive delay line technology for storage in their earlier calculators, before the time that integrated circuits took over the storage duties. They included Friden(Singer) (all of their in-house designed machines used delay lines, e.g., 130, 132, 115x, 116x), Canon(which made machines for Monroe), Wyle Laboratories (WS-02 and Busicom 202, 207 and 2017), Olivetti (Programma 101 & follow-ons), Sony(early Sobax), Victor(1400-series), Monroe(EPIC 2000/3000, 820/820A), Diehl(which made machines for SCM and Victor), and Olympia. -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com From echristopherson at gmail.com Wed Mar 15 11:07:05 2017 From: echristopherson at gmail.com (Eric Christopherson) Date: Wed, 15 Mar 2017 11:07:05 -0500 Subject: I hate the new mail system In-Reply-To: References: <8081e31ffd8e4ce6abdcaa1c48ac16e5@livingcomputers.org> <0625918f-47a6-4e73-6e46-396d5c9cbb06@sydex.com> <7844bcc8-c063-da0b-ad5a-0e81f7396f9f@gmail.com> <201703061330.IAA00599@Stone.Rodents-Montreal.ORG> <201703061733.MAA22646@Stone.Rodents-Montreal.ORG> <5c8dc30b-f205-d1fe-7bdc-5d906b5c9561@dunnington.plus.com> <817e28b4-215f-883f-01ed-92f2988cf7bf@dunnington.plus.com> <377cb432-1749-94e3-3e11-714e9d8e923a@dunnington.plus.com> <56e6dbb3-d8ec-3226-941b-2d28a429affb@jetnet.ab.ca> Message-ID: On Wed, Mar 15, 2017 at 4:44 AM, drlegendre . via cctalk < cctalk at classiccmp.org> wrote: > I was wondering why 99% of my cctalk shows up as "read mail".. =/ > > What a PITA, I can't tell what I have read from what I have not read - is > this part of the 'new' system? > You mean in Gmail?

That never happened, except for in certain areas, like server and HPC applications. As for smart-phones, it was Apple that introduced the idea of having smart-phones that were almost all battery and display, and using a purely graphical/touch interface. That class of device might have emerged eventually without Apple, but it's a fact that most of the mobile phone vendors had to do a lot of redesign in a short time after the iPhone was introduced (or a few months before, in the case of Google). If you haven't guessed, I like Apple ? for several reasons, but mainly because they make good, solid products that work well, and they actually work well for both ordinary users and enthusiasts. I have absolutely no problem with paying a little extra for a computer that lasts a little longer, keeps its value longer and works better in many ways, both subtle and obvious.

A closed system (aka "monopoly") has significant characteristics. 1) lack of difficulty integrating "other" peripheral stuff, through greater quality control, and INABILITY to add "other" peripheral stuff. Examples: a) MFM V RLL V ESDI V SCSI hard disks - much more struggle for users than "here is THE drive. Buy it. It JUST works." (Q: which meaning of "just" is that? simply? or barely?) b) specific example: Sunshine EPROM programmer (ISA almost free) specific example: ECC memory board (I don't think that Apple was even using parity) 2) MAJOR hurdles to development of an after-market industry. I've heard that Jobs was displeased when he was shown the numbers of what percentage of Apple2 disk drives were being purchased from vendors other than Apple. Woz ENCOURAGED an after-market ("open" system) Jobs sought to eliminate or at least rein it in. A closed system tends to be more profitable to the controller of it, but can be presented to the public as a means of quality control. Check out the "right to repair" link that Chuck gave us!

On computers, the OS is predominantly Windoze and Apple, with Linux and Chrome as less common, but present alternatives. on Phones, the OS is predominantly Android and Apple.

(Having said that, I salute the Lisa/Mac > people for doing a very good job of producing a excellent user interface.) "copied from" V "based on" V "inspired by"? Apple didn't "steal" it; the PARC researchers encouraged them to go with it. Apple was not that open when it was their turn to be copied from, when DRI produced GEM, or MICROS~1 produced Windoze 2. (There was a conflict, that keeps recurring in this industry! Apple had agreed to let MICROS~1 use certain stuff in Windoze; but then felt that Windoze 2 was a different product (citing "ALL NEW!" marketing) that wasn't included in the agreement. But, that is not the only time. Seattle Computer Products was "grandfathered" royalty free unlimited license to MS-DOS. When SCP was on the rocks and considering selling out to AT&T, etc. ("assets include unlimited license to MS-DOS"), MICROS~1 took the stance that that would not apply to anything but Verion 1. In an uncharacteristically reasonable move, MICROS~1 bought SCP, keeping it off the market without a battle.) > > - The one-button mouse. > Err, some of us don't see that as an 'improvement'... :-) some point to "cognitive delay" some point to simpler instructions in documentation I loved the Logitech 3 button mouse.

The whole idea of an "operating system" seems to have morphed into the notion of a user interface. To my way of thinking,t he various flavors of Linux are really a user interface build on a single operating system. I recall that back in the days of Windows 95, MS defended it as an "operating system" (re: the default inclusion of MSIE in the same), rather than a user interface built on top of MSDOS. I once had a fellow proclaim that his group had constructed an entire operating system in COBOL. When I asked him about his file management, he said that it was handled by the kernel and not the operating system. One thing you can depend upon in this field is the inconstancy of definitions. I always wondered about the wisdom of single-sourcing storage devices such as the Next optical drive, the Twiggy or the SuperDrive of the early Macs. --Chuck From geneb at deltasoft.com Wed Mar 15 15:42:25 2017 From: geneb at deltasoft.com (geneb) Date: Wed, 15 Mar 2017 13:42:25 -0700 (PDT) Subject: Pair of Twiggys In-Reply-To: References: <20170315153721.2BAA718C092@mercury.lcs.mit.edu> Message-ID: On Wed, 15 Mar 2017, Warner Losh wrote: > On Wed, Mar 15, 2017 at 1:13 PM, geneb via cctalk wrote: >> On Wed, 15 Mar 2017, Fred Cisin via cctalk wrote: >> >>> Below the user interface, is Android very similar to Linux? >>> >> I'm pretty sure Android runs on top of Linux. > > Android runs a hacked BSD libc on top of a linux kernel.

The administration wanted it to be remedial job training for the digital sweatshop, and never go past what commands do you do to format a disk, etc., and called for discontinuing the class once Windoze95 came out. I tried, instead, to create an understanding of what an OS was, as well as how to use it, and how to deal with problems. I dealt with sector editing repair of directories, etc. (In creatively handling user interface problems, I had a test question of: "You have a PC-DOS 3.30 PS/2 with a damaged keyboard (Pepsi Syndrome). There are other computers handy, but no other keyboards with the right connector. The 'A', 'C', and 'D' keys won't work! List some ways that you can copy files from the hard disk onto floppies") Among the answers that I would accept were: using and the numeric pad, creating a batch file on another computer, even "REN X?OPY.EXE XBOPY.EXE". One fellow included enough detail about cleaning key contacts and/or splicing the keyboard cable onto another one that I accepted that. I even accepted a moderately detailed description of how to remove the hard disk and connect it as temporary second HDD on another computer. (definitely a question of come up with a way, not "single right answer") I started the internals discussions with "DOS est omnis divisa in partes tres", and wrote on the board: BIOS(usually ROM)/BDOS/CCP (Console Command Processor) ROM&IO.SYS/MSDOS.SYS/COMMAND.COM ROM&IBMBIO.COM/IBMDOS.COM/COMMAND.COM hardware interface/file management/user interface We then spent some time on what each of those parts was. It doesn't HAVE TO be three parts, but those are a reasonable division. I loved how PC-DOS 1.00 documentation included partial description of what was needed to write a replacement command processor! > One thing you can depend upon in this field is the inconstancy of > definitions.

I was surprised that Jobs didn't make the Lisa floppy 5.0 or 5.5 inches, and used a relatively standard drive for the Mac. I would have thought that he would want people to buy even their media from Apple. For people who think that that is absurd, remember that there have been more than one machine that was capable of formatting it's own diskettes, but was not supplied with a FORMAT program. -- Grumpy Ol' Fred cisin at xenosoft.com From ams at gnu.org Wed Mar 15 16:34:19 2017 From: ams at gnu.org (Alfred M.

Twiggy drives seemed to be junk even new, which is why they changed the model to use the Sony 3.5" drives. -----Original Message----- From: Chuck Guzis via cctalk Sent: Wednesday, March 15, 2017 4:40 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Pair of Twiggys I always wondered about the wisdom of single-sourcing storage devices such as the Next optical drive, the Twiggy or the SuperDrive of the early Macs. --Chuck --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From toby at telegraphics.com.au Wed Mar 15 17:55:39 2017 From: toby at telegraphics.com.au (Toby Thain) Date: Wed, 15 Mar 2017 18:55:39 -0400 Subject: Pair of Twiggys In-Reply-To: <01QC0MP3EM4K002QSL@beyondthepale.ie> References: <20170315153721.2BAA718C092@mercury.lcs.mit.edu> <20170315191007.GD3511@ns1.bonedaddy.net> <01QC0MP3EM4K002QSL@beyondthepale.ie> Message-ID: <4c4870cc-6fa7-8d83-93f9-092789d78894@telegraphics.com.au> On 2017-03-15 5:17 PM, Peter Coghlan via cctalk wrote: >> >> The whole idea of an "operating system" seems to have morphed into the >> notion of a user interface. >> >> To my way of thinking,t he various flavors of Linux are really a user >> interface build on a single operating system. >> > > Has anybody else noticed that the meaning of "portable code" seems to have > morphed into "can be built on two or three different flavours of Linux"? 1983.

Message-ID: Hi folks, this might be quite interesting for the folks that miss front panel switch handles! As some of you might know I'm currently working (a bit) on a new batch of Omnibus USB boards. And I have announced that there will be a kind of handle for the boards this time... I went to my neighbour and showed him some bits and pieces. He has a nice little workshop for concrete artwork (https://www.fritzundfranz.com/) and spent a lot of time into perfecting his moulding skills. I gave him a pdp8/e yellow switch handle with broken axle (usual problem) to try what can be done. Today I came home and he gave me the piece saying that he was unable to replicate it. I took it (a bit frustrated) and stated that he has somehow ruined the surface... Haha! It was the replica! He told me that this was a first "fast" shot including a "rough" approximation of the colour. I was stunned! Here you can see pictures. Even the defects of the original have been replicated. https://www.dropbox.com/sh/sih4qrrw4o3zgbh/AACf7kY7MbGDLt5FYJgfI4kDa?dl=0 He told me that it was a bit difficult to get the holes at the side right. I think that it would be no problem if they'd be more shallow or even gone. * His material is less translucent than the original. Won't probably change. So a perfectionist could spot the difference. * He states that he can hit colors even better! (Think of the special colors!!!) * The axle stubs would be omitted and made of steel (something I already plan for repair of that weakest point) * He is able to produce flawless finish (remember: it's a raw prototype!) This is not my business. I told him that I'd ask around if there would be serious interest. He is not in vintage computing and does not work for free. So one piece would probably cost around 5-15 EUR each, depending on demand, color etc. Please give some feedback!

I agree that for this level of molding precision the pivot axle would be better if done as a separate piece and press fitted. Steel would be fine, brass rod would also be ok and softer to machine. A small jig could be made to cross-drill the hole accurately. Same for the side holes just using the depression as the centre point. Your neighbour has done an excellent job there, well done.

Even if it is moulded perfectly - the axle will still be THE point of failure. So the replica will be better than the original.

I think that he can make everything glossy. For matte finish, we'd need a perfect original or see if we can somehow prepare the mould.

They have > no function and are nearly invisible. They aren't structurally functional and they aren't visible, *but* they have a purpose... when making a large object, the side holes ensure that the deepest point of the object is shallower than if the hole weren't there. This accomplishes two things - the center of the part cools and hardens faster, plus there's less overall plastic so the shrinkage factor as it cools is less likely to put a depression/flaw where it might be visible. Negative space still has a function. It's a common thing with injection-molded plastics to consider wall thickness and body thickness. It's not about "saving a few cents in plastic", but it is about less effort to get faithful parts. > If there's enough demand, I'll probably manage the > distribution/shipping/ordering. Cool. I don't know if folks would want to get 20-30 toggles at 15 Eur, but closer to 5 Eur is in striking range What is the material, BTW? > I think that he can make everything glossy. For matte finish, we'd need a > perfect original or see if we can somehow prepare the mould. My memory of all the toggles I've handled (no pun intended) is that they have a glossy finish, not a matte finish. -ethan From bfranchuk at jetnet.ab.ca Wed Mar 15 21:56:36 2017 From: bfranchuk at jetnet.ab.ca (ben) Date: Wed, 15 Mar 2017 20:56:36 -0600 Subject: DEC frontpanel switch replica!

I can tell you exactly what the Diehl Combitron does; I have a running bachelor thesis for a student who is developing an emulator and assembler for that machine, and we have also disassembled (but not yet understood) the firmware (contained on the metal tape) of the machine. In fact, it uses two magnetostrictive delay lines, one is called the R delay line containing 219 bits plus one external in a flip-flop. The other is called the M delay line with a total of 10889+1 bits. The main clock of the machine is 1 MHz thus a bit time (called P) is 1 ?s. The R line holds four words ? 55 bits, one in the I phase P bits time, one in the I phase /P bits time, one in the /I phase P bits time and one in the /I phase /P bits time. The instructions are always fetched from the I phase /P bits and executed in the /I phase. The M line holds a total of 99 P words and 99 /P words. The phase between P and /P changes every M cycle During the loading phase (e.g. at power on or after a 'e1' order) the R line is filled with the contents coming from tape and then executed. Usually the code just transfers the other three words of the R line somewhere into the M line and restarts the loading phase for the next block. After loading the last block a fill instruction "jumps" to the entry point of the firmware. The fill instruction transfers four words from the M line to the R line.

Here are a few comments. 1. Rather than single items a full set to suit say a PDP-8/e might be an idea. 2. This would prevent color mismatches where replaced. 3. Any chance of say 8/i rocker switches. 4. Whats the production method? 5. Whats the production rate? 6. Batch to batch color matching? Rod Smallwood -- There is no wrong or right Nor black and white.

I received an Intel iPSC/860 supercomputer, but it?s lacking the Intel SRM (System Resource Manager), without which the system is a boat anchor. The SRM is an Intel 386 desktop machine, with a SYP301 motherboard and a plugin card to connect it to the iPSC/860. There?s a cable coming from the iPSC with a 25-pin D connector, which I believe is the connection to the SRM. It?s not a regular serial port, but a bidirectional 2.6MByte per second connection. The interface card likely uses a bunch of Xilinx chips (the interface cards on the iPSC node boards do). I have not been able to find a picture of what the box looks like on the outside, so I have no idea. So, I?m looking for one of these, preferably one the owner would be willing to part with :-) Camiel From geneb at deltasoft.com Thu Mar 16 10:28:12 2017 From: geneb at deltasoft.com (geneb) Date: Thu, 16 Mar 2017 08:28:12 -0700 (PDT) Subject: Pair of Twiggys In-Reply-To: References: <20170315153721.2BAA718C092@mercury.lcs.mit.edu> <20170315191007.GD3511@ns1.bonedaddy.net> <01QC0MP3EM4K002QSL@beyondthepale.ie> <4c4870cc-6fa7-8d83-93f9-092789d78894@telegraphics.com.au> Message-ID: On Wed, 15 Mar 2017, Warner Losh via cctalk wrote: > I'm waiting for the rise of cell phones to make it > > 202x All the world's an ARM running Android > ....on Linux. :) g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.diy-cockpits.org/coll - Go Collimated or Go Home.

I can tell you exactly what the Diehl Combitron does; I have a running bachelor thesis for a student who is developing an emulator and assembler for that machine, and we have also disassembled (but not yet understood) the firmware (contained on the metal tape) of the machine. In fact, it uses two magnetostrictive delay lines, one is called the R delay line containing 219 bits plus one external in a flip-flop. The other is called the M delay line with a total of 10889+1 bits. The main clock of the machine is 1 MHz thus a bit time (called P) is 1 ?s. The R line holds four words ? 55 bits, one in the I phase P bits time, one in the I phase /P bits time, one in the /I phase P bits time and one in the /I phase /P bits time. The instructions are always fetched from the I phase /P bits and executed in the /I phase. The M line holds a total of 99 P words and 99 /P words. The phase between P and /P changes every M cycle During the loading phase (e.g. at power on or after a 'e1' order) the R line is filled with the contents coming from tape and then executed. Usually the code just transfers the other three words of the R line somewhere into the M line and restarts the loading phase for the next block. After loading the last block a fill instruction "jumps" to the entry point of the firmware. The fill instruction transfers four words from the M line to the R line.

I thought Djikstra, but it turned out to be Stan Kelly-Bootle: "The definition of FORTRAN from the "Devil's DP Dictionary", by Stan Kelly-Bootle: "FORTRAN n. [Acronym for FORmula TRANslating system.] One of the earliest languages of any real height, level-wise, developed out of Speedcoding by Backus and Ziller for the IBM/704 in the mid 1950s in order to boost the sale of 80-column cards to engineers. In spite of regular improvements(including a recent option called 'STRUCTURE'), it remains popular among engineers but despised elsewhere. Many rivals, with the benefit of hindsight, have crossed swords with the old workhorse ! Yet FORTRAN gallops on, warts and all, more transportable than syphilis, fired by a bottomless pit of working subprograms. Lacking the compact power of APL, the intellectually satisfying elegance of ALGOL 68, the didactic incision of Pascal, and the spurned universality of PL/I, FORTRAN survives, nay, FLOURISHES, thanks to a superior investmental inertia."

Even the IBM 650 had a FORTRAN of sorts 2. One thing that was a sales point for the PDP-8 back in the day was that for about $5K, you could get a computer that would run 4K FORTRAN: http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp8/software/DEC-08-AFCO-D_4K_FORTRAN.pdf 3. FORTRAN was originally released, IIRC for the IBM 709, and was a card-only system; versions for the 704, and, as previously mentioned, the 650. I've used card-only FORTRANs on the 1620 and 1401. 4. The 8080/Z80 had FORTRAN, and I suspect there was also a FORTRAN for the 8008 (if APL on the 8008 was possible, surely FORTRAN was). 5.

I know of FORTRAN implementations for one's complement machines with word length of 24, 27, and 60 bits, decimal machines (IBM 1620), two's complement machines of 12, 16, 48 bit words, just to pick a few. FORTRAN implementations tended not to be all that demanding of resources: 4k words is a typical minimum. I think a lot of high level languages are quite portable. ALGOL is not as widely ported but not because it's inherently harder. PASCAL was ported to many different machines too. C is a bit of an anomaly because it's more like a high level assembly language, so it has portability limitations that many other high level languages don't run into. paul From hachti at hachti.de Fri Mar 17 08:43:21 2017 From: hachti at hachti.de (Philipp Hachtmann) Date: Fri, 17 Mar 2017 14:43:21 +0100 Subject: I hate the new mail system In-Reply-To: <3515ADFA26064845BC65479CE6276B18@310e2> References: <8081e31ffd8e4ce6abdcaa1c48ac16e5@livingcomputers.org> <20170228215001.D9185A58595@yagi.h-net.msu.edu> <201702282254.RAA05100@Stone.Rodents-Montreal.ORG> <3e67191c-319c-eebe-6df1-38ade2bccd6f@sydex.com> <7d5b91e2-9a85-1d9f-d29a-9a510e106c71@gmail.com> <3672896e-7498-ad86-941a-34296d007c0a@tds.net> <0625918f-47a6-4e73-6e46-396d5c9cbb06@sydex.com> <7844bcc8-c063-da0b-ad5a-0e81f7396f9f@gmail.com> <00b001d29e94$2e6f24f0$8b4d6ed0$@classiccmp.org> <3515ADFA26064845BC65479CE6276B18@310e2> Message-ID: On 03/16/2017 10:07 PM, Mike Stein via cctalk wrote: > I'm pretty confident that every member of the list appreciates the > time, effort and whatever else you and certain others have > contributed to keep this list humming as well as it almost always > does; Full ack, of course!

This is a one?s complement, 16-bit machine and the Fortran compiler is now functional in 16KW of available space (a smaller version (12KW) was available but I don?t know if any copies survived). The source code for the compiler is available on Bitsavers - it?s written mostly in Fortran. John.

Not quite true. ALGOL was the first choice for a couple of architectures: Electrologica X8, and the Burroughs 48-bit mainframes. And I supposed you could claim that status for Bliss in the case of VAXen, though in a different sense there was a whole set of high level languages that were there day 1 because the architecture envisioned all of them (and any combination of them). paul From cclist at sydex.com Fri Mar 17 13:56:20 2017 From: cclist at sydex.com (Chuck Guzis) Date: Fri, 17 Mar 2017 11:56:20 -0700 Subject: Architectural diversity - was Re: Pair of Twiggys In-Reply-To: References: <57b958c7-eefd-b2bc-5993-7b7a42309b19@jetnet.ab.ca> <765d682d-cfc1-deed-e345-015c4c01b0a9@sydex.com> <9231cf00-fe35-af1d-1641-fc11c681ceff@sydex.com> <3ae3cb89-9452-274e-3c8e-a7703c94d094@sydex.com> Message-ID: <55da3360-9b08-f355-71e6-7c86d86763d4@sydex.com> On 03/17/2017 11:41 AM, Paul Koning wrote: > Not quite true.

Well, okay--the European-American divide must be taken into account--and the Burroughs B5000 architecture was sui generis. But by and large, FORTRAN, at least in North America, was the first language of choice in implementation--after assembly, if one can call assembly a language--many would call it "symbolic coding"; using symbols instead of numeric addresses. --Chuck From cclist at sydex.com Fri Mar 17 14:00:51 2017 From: cclist at sydex.com (Chuck Guzis) Date: Fri, 17 Mar 2017 12:00:51 -0700 Subject: Architectural diversity - was Re: Pair of Twiggys In-Reply-To: References: <57b958c7-eefd-b2bc-5993-7b7a42309b19@jetnet.ab.ca> <765d682d-cfc1-deed-e345-015c4c01b0a9@sydex.com> <9231cf00-fe35-af1d-1641-fc11c681ceff@sydex.com> <3ae3cb89-9452-274e-3c8e-a7703c94d094@sydex.com> Message-ID: <2abe9574-bea1-5270-17b4-a1aec6ea589b@sydex.com> On 03/17/2017 11:41 AM, Paul Koning wrote: > Not quite true.

I'll also consider that there are probably other exceptions. Did FORTRAN or RPG have the honor of "first implemented" on the S/360 Model 20? My gut says RPG. --Chuck From dkelvey at hotmail.com Fri Mar 17 14:17:47 2017 From: dkelvey at hotmail.com (dwight) Date: Fri, 17 Mar 2017 19:17:47 +0000 Subject: AC magnetic field strengths In-Reply-To: <58CB2871.1080606@cimmeri.com> References: <92bfdf07-06d2-bb4d-771b-1810637c9217@bitsavers.org>, , <58CB2871.1080606@cimmeri.com> Message-ID: Al You should also measure at about 1 inch.

Why would I save things at significant expense and continue to collect them for 20 to 40 years then "get rid of that junk". I am lucky not o have such a person in a significant place.

A colleague of mine carried out some ecological fieldwork ~30 years ago, and her results are stored on eight magnetic tapes (two of 7" diameter, one 8.5", and five 10.25"). The data would be incredibly useful to look at, as the study was looking at how restored mines changes over time (the study is somewhat described here; https://www.jstor.org/stable/20038221?seq=1#page_scan_tab_contents). If we could get these original data, we could compare how the mine is now with how it was then, which would be phenomenally useful to conservation biologists trying to conserve and restore damaged ecosystems. Do any of you have any ideas as to how I might get the data off this tape? I live and work in Utah (USA), but I would be willing to travel a little ways if it meant getting the things read off into a computer! Thanks again for your time, Will Pearse --- Need a phylogeny?

Do you have an honest to gosh differential probe, or are you using some other technique? (If you have a differential probe, then the TU56 manual indicates that you should see 10mv-12mv (the addition of the two paired heads together), so as a first guess I am guessing you are looking at the coils one at a time. The reason I ask is that the TU56 that I use most often has gotten a bit cranky over the years. Generally I can read and write, but I do typically see some errors - unacceptably many, and it *seems* that the longer the machine is on, it seems the more mark track errors I get when running the ZTCC?? diagnostic (test 3). I don't have a differential probe, and the A-B math function on my Rigol DS2072 scope is not anywhere near fast enough (though maybe a firmware patch which I have downloaded will help, but I doubt it will help because their is a lot of HF noise on the signals when measuring voltages this low). However, if I apply a 50KHz low pass filter on the signal on the scope, then sometimes I can see a 5mv per coil signal using an ordinary probe. I say sometimes because the scope seems to have some firmware problems so it isn't consistent in its behavior. (I have downloaded a firmware update that *might* help). I don't really doubt my heads at this point - certainly nothing is open - I can measure each coil at about 1.5 ohms (3.0 ohms across both), but it is something I would like to make sure I know how to do. Also, have you degaussed your heads? If so, how? I ask because some of my symptoms could point that way (I have yet, for example, to test with a tape, have it get worse, then go back with the machine "cold" and see if it gets better - and if it doesn't, that could point to demagnetized heads.)

However, the CF entry on Wikipedia says: "Most CompactFlash flash-memory devices limit wear on blocks by varying the physical location to which a block is written. When using CompactFlash in ATA mode to take the place of the hard disk drive, wear leveling becomes critical because low-numbered blocks contain tables whose contents change frequently. Current CompactFlash cards spread the wear-leveling across the entire drive. The more advanced CompactFlash cards will move data that rarely changes to ensure all blocks wear evenly." ... I'm a little wary about the way it says "most CF cards", implying that there are some out there which don't do any wear-leveling at all. So, the obvious question: is there a way of knowing which cards are going to be good and which are useless as IDE replacements? Maybe by age, capacity, manufacturer? I'd prefer not to invest time into setting software up only to find that the card fails in a matter of weeks. cheers Jules From alexandre.tabajara at gmail.com Sun Mar 19 11:05:05 2017 From: alexandre.tabajara at gmail.com (Alexandre Souza) Date: Sun, 19 Mar 2017 13:05:05 -0300 Subject: Looking for cassete basic rom code Message-ID: <5BA8BBFA7397418C82C9C9D8C7339679@deskjara> Dear friends Is it allowed to request a ROM code?

In my opinion, the object-oriented successor to COBOL is called Java - it's similarly verbose, and like COBOL, originally intended for average, fungible programmers.

They are not run continuously, but have been run for months at a time. These use regular-size SD cards as the "disk" for a Linux OS. I did set the noatime flag on the file system. They are still running on the original SD cards. I have a Beagle Bone running LinuxCNC under a Debian-based distro, and I fire it up at various times to text boards I make, and it is still running the original micro-SD card.

It's almost impossible without trying to be an ass to the card to have it fail in a few weeks. I've run 64MB cards in Soekris boxes for a decade w/o any problems. The key, as with all flash purchases, is to buy the best, fastest you can rather than the cheapest you can. But most unix systems can do many things to mitigate wear. There's dozens of tutorials about mounting noatime (to keep access times from being updated), to more advanced features like putting /var/tmp and friends on memory disks, etc. With a 486, though, that might not be an option. Not sure what kind of system you are migrating though... CF cards tend to be much more compatible with systems than SD card adapters, but on extremely old system can be picky even with CF cards. I had a system back in the day not present the CF card as a bootable device because something in its ID string was a bit wonky to it. SD cards tend to be crap too without careful selection (which usually means getting a couple of the faster cards and hoping that at least one of them is good). These days, it's more a precaution than an actual requirement though, but see below. For $40 you can get a 32GB Lexar Professional that boasts 1066x speed and UDMA7. You'll likely not do UDMA at all in a system of that age. DMA is another area where you have to buy the right CF card (though it's hard to buy the wrong kind new, random used stuff is a crap shoot whether all the pins needed for UDMA are present). If you have problems, try setting the to PIO. Seems like overkill. If you are looking for a smaller card because the BIOS just can't cope with anything that big, you'll need to buy the professional grade used cards, though that too is a crap shoot (so buy several). If you have a reasonable sized system (say 2GB) the way you cope with failure is to backup an image every so often with DD and just blast it out to a new card if the one you get fails. But if you do that, the size has to be >= the old one. And with a 486, you likely don't have an LBA BIOS, so you need to make sure the geometry matches which can be tricky. The geometry reported by CF<->USB adapters will almost certainly be different than what the CF<->IDE adapter reports. So good luck!

There was another FORTRAN 66 available fro the S/360, but you usually saw it on the lower models (25, 30, 40). It was called "Basic FORTRAN IV" or sometimes "USA Basic FORTRAN". There doesn't seem to be a manual in S/360 section for this on bitsavers. I recall that it was a slim little packet. It was brutal--basic INTEGER, REAL and DOUBLE PRECISION data declarations; blank COMMON only; arithmetic IF only, computed and unconditional GO TO--and the bugbear of many programmers: strict enforcement of "mixed mode" prohibitions. File I/O was reasonable, I suppose. A maximum of 6 characters in a variable name, stuff like that. Better than some of the stripped-down FORTRAN II versions, which often didn't even include type declarations. FORTRAN IV was a step forward--vendor "extensions" of FORTRAN II were getting out of hand--contrast some of the conventions of, say, 7090 FMS II/IBSYS fORTRAN with other vendors. For example, punching a 'B" in column 1 indicated a "logical/Boolean" expression and so on... Still, vendors kept extending their FORTRAN IVs. I think I remarked on a CDC syntactic extension that resulted in the ability to write an ambiguous statement, with no clear way to resolve the meaning. I believe that Univac, at one point, boasted an 1100 "FORTRAN V". That's chutzpah for you. "FORTRAN VI", of course, was PL/I. F77 tightened that up and brought out the notion of having to flag any non-ANSI syntax. F90 was clear in that vendor extensions were to be disabled by default; i.e., the user must explicitly enable them. F90 was, to me, the point of departure. Many statement types were deprecated; since the world was no longer coding on cards, free-format input was standardized. Extensions for high-end supercomputers were codified, etc. Reserved words made their appearance--in previous versions, the notion of "whitespace" was introduced. It was perfectly legitimate to name a variable "FORMAT" or "REAL" and write it as "F OR M AT", though I suspect that few ever did. The Fortran of today resembles FORTRAN II in the same way that COBOL 2014 resembles IBM COMTRAN. But, mutatis mutandis, Fortran/FORTRAN still lives. --Chuck From cclist at sydex.com Sun Mar 19 13:42:10 2017 From: cclist at sydex.com (Chuck Guzis) Date: Sun, 19 Mar 2017 11:42:10 -0700 Subject: CF cards as storage - wear leveling In-Reply-To: References: <91dd6ff7-6968-5f2b-a3ae-c735a9cd00ce@gmail.com> Message-ID: <377716d9-4cec-fe44-690e-f2b3cb1c48c8@sydex.com> On 03/19/2017 11:20 AM, Warner Losh via cctalk wrote: > Just about ANY CF card you buy today new will have wear leveling. > It's almost impossible without trying to be an ass to the card to > have it fail in a few weeks.

Not sure what kind of system you are migrating though... If you're worried about write wear on a CF card and can do with higher power consumption and somewhat slower speed, use one of the "Microdrives" offered by IBM, Hitachi or Seagate in past years. I believe that capacity of 12GB may be the upper limit. They're comparatively inexpensive, as NOS items. I ran a 5GB Seagate drive for about 5 years 24/7 in a mailserver with no issues. --Chuck From cctalk at beyondthepale.ie Sun Mar 19 13:44:22 2017 From: cctalk at beyondthepale.ie (Peter Coghlan) Date: Sun, 19 Mar 2017 18:44:22 +0000 (WET) Subject: CF cards as storage - wear leveling In-Reply-To: <58CEC90F.6010303@pico-systems.com> References: <91dd6ff7-6968-5f2b-a3ae-c735a9cd00ce@gmail.com> Message-ID: <01QC62HU0JJE00159O@beyondthepale.ie> > > I don't think anybody is actually using real CF cards > anymore, they are about a decade out of date. > > Jon > Jon, This is the list where we discuss using stuff that's a decade and more out of date.

I've successfully read tapes that were stored in an uncontrolled Michigan attic for 20+ years. VMS Backup format isn't that hard to deal with: there are at least one or two open source tools which can read most save sets, and feeding an image to an actual VMS system in emulation is easy too. The worst threat is the "sticky shed" issue, wherein the binder which holds the coatings onto the tape backing absorbs moisture and gets gooey. A number of approaches have been described in the literature, from mechanically removing the back coating applied to some media to reduce static and other issues, to chemical applications, to baking out the moisture. > Some other people have a lot of experience with baking the tapes at > low temperature to improve the chances of good data recovery, you you > might see if they want to do it, first. I've had good luck with the lowest of tech solutions: a food dehydrator. Many libraries have used convection ovens. Target temperature seems to be in the neighborhood of 130-140 degrees. I've seen recommendations for 2-4 hours, but I seem to have better luck with 24.

I'm reminded of a T-shirt sold while I was in college (mid 1970s) with this text: (.)(.) IKF4084I I looked that up in Messages and Codes, found a pointer to the IBM COBOL messages manual, where I found this message text: "Questionable use of parentheses accepted with doubts as to meaning".

Recalling the messages from December, it looked like proper operation of the reset circuitry at power-up expected the presence of the battery to power the reset circuitry with 12V prior to the 5V bus coming up. It looks like you could add a reset switch to the unit by paralleling R406 (11K) with a NO pushbutton switch and ~ 4.7 uF cap (all 3 in parallel). Closing the pushbutton switch simulates the absence of 5V. The cap provides a little debounce delay, but may not even be necessary.

Some further detective work found a leaky 1500uF cap in one of the B+ supplies which was causing the 'surging' issue on the scope. For good measure I replaced all six 1500 and 3000uF caps even though ripple was low. Better safe than sorry and if it means pulling that chassis and its covers again, all the better. I attempted to weigh it on my shipping scale, but it only registers to 100 lbs and the indicator flew right past that. There had been a small thermal event in the AC junction box that the twist lock connector mounts to, and I suspect it occurred pre-60's refurb. It's not too surprising as the wiring on the computer side is aluminum and the feed is copper. The box needed replacing but was a unique Hubbell variation of a std 4" box with special ears.

Some further detective work found a leaky 1500uF cap in one of the B+ supplies which was causing the 'surging' issue on the scope. For good measure I replaced all six 1500 and 3000uF caps even though ripple was low. Better safe than sorry and if it means pulling that chassis and its covers again, all the better. I attempted to weigh it on my shipping scale, but it only registers to 100 lbs and the indicator flew right past that. There had been a small thermal event in the AC junction box that the twist lock connector mounts to, and I suspect it occurred pre-60's refurb. It's not too surprising as the wiring on the computer side is aluminum and the feed is copper. The box needed replacing but was a unique Hubbell variation of a std 4" box with special ears. I couldn't find anything even close to that at any of the supply houses online, probably because it violates today's conductor fill rules (it's only 1" deep but the socket consumes most of that depth and 75% of the area).

Algorithm 1 dates from 1960 and is in Algol; indeed all of Volume I and a good part of Volume II are exclusively Algol. You don't hit FORTRAN until about 1968 (somewhere around Algorithm 330). After that, you'll see pages and pages of FORTRAN. I do think that Algol is far more elegant for describing algorithms than FORTRAN; but the sad fact is that many (US-based) programmers didn't speak Algol. --Chuck From witchy at binarydinosaurs.co.uk Sun Mar 19 18:01:56 2017 From: witchy at binarydinosaurs.co.uk (Adrian Graham) Date: Sun, 19 Mar 2017 23:01:56 +0000 Subject: 8085 RESET In-Reply-To: Message-ID: On 19/03/2017 19:59, "cctalk" wrote: > On 2017-Mar-18, at 5:21 PM, Adrian Graham via cctalk wrote: >> >> 8085-based phone system weirdness continues and I'm beginning to wonder if >> the PSU rails are all coming up in time for RESET to go high - given there's >> 4116 DRAMs in there isn't there supposed to be a proper power up order? >> >> While I look at using a 20-pin ATX PSU to run this machine temporarily I >> need a safe way to reset the CPU rather than constantly power cycling.

I've just checked the image you're referring to and the resistor numbers are offset so it looks like R406 is the top one of three where it's actually the middle one.

Fortunately, my scope can go down to 500uv/division (5mv/division with the 10x probes). First, updating to the latest software on my DS2072A helped - but just a little. Getting the settings just right - not all of them immediately intuitive - helped more. (BTW, if you do not have a DSO, they are WONDERFUL. If you haven't seen one of these things in action, go to the EEVBLOG on YouTube My normal analog Tek scope now has a tear in its eye. Poor thing - it served me well. I got my scope during a time when Rigol had a promotional offering, so I got the decode features and a few other things that one might normally pay extra for. I got my from Saelig and they offered a discount to match that offered by other vendors who join the EEVBlog *forum*). https://www.youtube.com/watch?v=_TSr9nFN1GU Here is what I learned over the past couple of days: 1. I set the bandwidth limit on the input to 20MHz. So this limits the bandwidth before it even gets to the Math processing and reduces the sample rate. Maybe this gives the 'scope more time to do other processing? Anyway, this made a VAST difference. I can still see the waveform without doing this, but it is attenuated and more quantized. 2. At times I did not have the 10x multiplier on the input channels set to match the probes, which meant my signal readouts were 10x off. This was another important mistake that lead to incorrect readings. (D'oh) 3. I then used the "Math" function on the scope and select a low bandwidth filter, and set it to 50Khz (more or less matching the TU56 manual's 60Khz identification of the Tek module they used). This gets rid of almost all of the noise (I live less than 2 miles from a bunch of TV and radio towers!) This way, I reliably get decent signal readings off of the heads. In fact, in this configuration, I could even set the Math to A-B and sometimes see the wave as the manual offers intended, though it was chock full of noise (unfortunately and understandably, the scope can't do both low filter and A-B at the same time.) (It might even be that I could use the scope to capture the data, and then post process it, but what I have now is just fine. It was helpful that I had reasonable confidence in the head to begin with.

It is set to make the motherboard memory decoder drop out half of the 512K from decoding as memory as well as disabling the memory if there is any. you put this option in to do the disable when you install the AT/370 card. It has 256K on board which fills in the other 256 K. When the 370 is running there is no difference in the operation of any software, as the dual ported memory is just memory to the AT. If you have a 256K AT this is a rare and exotic memory expansion board for all intents an purposes. The hosting software handles the dual memory as it needs. When the hosting software is running, and you have an IBM 3270 card which is compatible with the regular 3270 remote access software, you can either run that software and have a CUA connection over the 3270 coax to the mainframe, or a DFT session if you have that software. If you have the AT/370 software running there is a function key action which switches between a 3270 CUA session with your mainframe, which if you want it to be very useful should be VM of some sort (we has VM/SP5) running. With that session running you can file share with the mainframe's minidisks, initiate IND$FILE uploads and downloads from elsewhere (similar to FTP for the most part), and have a CUA VM session logged in. You can flip the PC to a CP / CMS session on your local 370 PC system as well. It sees both the local disk 30mb (unless you finagle the host software, about the limit), or you can map mainframe minidisks to your local VM, which is the real payoff. And there is a DOS session running in the smige off memory left, so you can copy files to / from the 30mb local AT disk (pretty much all you got room to run). And you can set up the printer port on the AT to be a legitimate 3270 printer if you have the mainframe 3270 port config generated to have a printer there. Would love to archive the entire site, it seems to have a lot of great well organized information.

I went off and did a little cursory (pun intended) research, since you've shown me up for relying on sketchy recall. I never saw these machines new at the time; I was a primary school pupil when the PC shipped and only in secondary school when the Mac did. This is just based on what I've read over the years. So, some cited Apple innovations. The first few come from the Lisa, AIUI, the later ones more from the Mac: * global menu bar * the desktop metaphor * the trash can * desktop icons for drives * drag-and-drop file manipulation * self-repairing windows * the Human Interface Guidelines and standardised UI across apps -- keystrokes, menu entries, etc. Citations: http://www.mac-history.net/computer-history/2012-03-22/apple-and-xerox-parc/3 http://www.folklore.org/StoryView.py?project=Macintosh&story=On_Xerox,_Apple_and_Progress.txt -- Liam Proven ?

Will try that. Limited success with that forum. Not critical of them, just my style doesn't run with how they do. I need to study if there is a way to get push feed from interesting threads or such. I don't peruse much on sites anymore, and prefer to have an RSS feed or such and scan that with one liners or so. I don't recall finding that, though I may have a registration. thanks Jim From geneb at deltasoft.com Mon Mar 20 13:47:45 2017 From: geneb at deltasoft.com (geneb) Date: Mon, 20 Mar 2017 11:47:45 -0700 (PDT) Subject: Looking for cassete basic rom code In-Reply-To: <27993baa-29e8-d9ac-e431-2e2dd197c992@jwsss.com> References: <5BA8BBFA7397418C82C9C9D8C7339679@deskjara> <27993baa-29e8-d9ac-e431-2e2dd197
