Maybe what I have is just a partial system.
There's nothing on my board that can run native CP/M (ie, no 8080 or Z80
processor). It's just one board carrying the 8088, RAM, (boot?) eprom, and
logic. It's not even clear how it connects to anything else--apart from an
empty dip socket in the corner and a couple of lugs to connect +5 vdc,
there's no obvious electrical interface. Of course, I have no documents to
help me :) Clearly I don't know what I'm missing: is there another base
board that's supposed to go with this "Co-Power" card?
Aha...it sounds like you just have the upgrade kit. To use this, you'd
need the CP/M computer it was designed for. I forget; did you mention that
it says ATR on it somewhere? I don't have a part number list to identify
which machine it's for, unfortunately.
Did they make a different model for each host
computer, or did they use a
single pcb design with different interconnects and/or eproms to suit each
target system?
To the best of my (limited) knowledge, it was the same board just modified
to interface to specific machines. Don Maslin might know more about the
magnitude of the differences between models.
I'd love to find out more.
