Re: Can you help identify two cards?

They are from a backplane type A2 clone. These typically would have as
many as 10 slots, though most had 9. So you could get 1-7 and Slot 0
had the CPU and 64K RAM, ROMs, etc. If the RAM and ROMs were not on
the CPU card, it would be 9 or 10 slots, with the CPU on it's own, the
RAM and ROM either together or on their own, and the game port and
sound on either another separate card, or two separate cards like you
have here.

By 'CPU' I mean the CPU and all the rest of the logic. A keyboard
would either hook up via 16 pin socket or IDC header.
