    I had never seen that Toshiba chip before. The 2716 was just a guess
based on the part number. I'd guess that it's 200ns RAM. Is it a 2kw chip?

    Actually, of 63 chips, only the 16 RAM chips, a 24-pin socket next to
the uP, and two 16-pin chips near the PIO and CTC chips are empty.

    Do you have any schematics or other info on this board?
