If you didn't get a keyboard one I'd beg the seller to connect you
with someone that did. Hopefully they will be willing to help you sort
out the keyboard at least. It can't be too impossible to recreate.
Software for development stuff is always so hard to find though. On
cassette tape I can't even imagine. Someone probably reused them for
Journey mix tapes.
I did end up with one of the Keyboards. Went down to pick it up this
morning, and as far as I can tell I have basically a complete system
(minus peripherals). Serial #16. 8080A CPU board, 5 8K RAM boards
(full of 2107's), an I/O board (tape and EIA) containing 256 bytes of
ROM (in an 8702), and the Keyboard/Video interface. Seems like a nicely
put together system. Very clean. The backplane is 100-pin but is
probably not S-100 (different form factor for the cards at least).
I can take pictures if anyone's interested.
Any recommendations for a programmer that can dump 8702s? (Reprogramming
might be a nice feature as well :)) I'd like to start with a ROM
disassembly so I can work out what this machine is trying to bootstrap
from (and how), and work from there.
Thanks,
Josh
