1. "Disk n" disk controllers, n=1, 1A, 1B,
2, 3, or 4.
2. "CPU nn" CPU cards, nn=85/88, Z, etc.
3. "Interfacer n" I/O boards, n=1 to 4
4. "System Support" boards, with real time clock, console port, etc.
5. "RAM nn" boards, nn usually greater than 16.
On a more
serious note, I looked inside and there was:
A Z-80 cpu card.
2 cards with 512K on them and were labled Disk something.
Well, then, these are your disk controller(s). The "something" that
comes after Disk is very important in identifying them!
The "512K" sounds like a Compupro board etch identifier, but I just
looked over my Compupro Disk 1's, 1A's, Disk 2's, and Disk 3's, and
none of them say 512K. Maybe it's a Disk 1B? Disk 4? A wire wrapped
(home-brew looking) card that looks like the 8" drive
interface.
What makes you think that it's the 8" drive interface? Look for the 50-pin
cable coming from the drive box and figure out where it's going. Another card
covered with 6116 Ram chips.
32 6116's gives you 64Kbytes, a comfortable amount for running CP/M-80.
Your description matches that of the Compupro RAM17, though lots of
of other manufacturers made similar boards that might be in your system.
