Nope... I suspected RAM disc cards because 512K is the AMOUNT of RAM I
counted (a board covered w/ 4116s). And there were no connectors to the
boards other than the card edge.
It sounds like an "MDRIVE/H" card. If so, it's a RAM disk board made by
Compupro. 512K was standard on them and each system could use up to 8 of
these boards.

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?
