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?

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?

I'd love to find out more.
