Hey there...
I'm going to slowly put together this page... It will be related to things I (am) doing. Hopefully, it will be mostly "fun" (In my opinion) stuff. If you would like to add something, send me mail to one of the addresses below. If you like what you see here, & want me to do a design for you, got to BC Computers home page. If you like what you see, & you want to hire me (I hope), go to my RESUME.
Now, on with the "fun" stuff
I built this with a (very) little help from someone else for my EE424 class. The schematics are shown below, but are also available HERE. Eventually, I will remove them from this page to save space. The computer is based on the i8086 microprocessor. The schematics include 8k of static RAM, and 8k of EPROMS. The EPROMS will hold the OS, while just about anything can be done with the RAM... The machine has a single RS232C asych serial port which can be connected to a dumb terminal to give input to the machine. It also has 2 parallel I/O ports available for external inputs. Included on this page (and in the package) is monitor.zip which includes the full source code & assembled binary to be put on the EEPROMs... Remember, the 8086 has a high & low memory bank, so the binary must be split into its odd & even components on the EEPROMs. This shouldn't be a problem, as most EEPROM burners have this capability built into their software... If you have ever used an SDK-80/85/86, the OS I have written for this thing is _VERY_ similar to the monitor program on those those... (IE read memory, copy memory, load memory {write your own prog in hex}, and execute from that point... Make sure to put a return statement at the end of your program ;)... Have fun!
