I've done some research on this card and learned that it was a coprocessor system that
enabled multiple CP/M sessions on a Unibus machine, most often a VAX with a Unibus
cabinet. It has four full and distinct Z80 microcomputers on the board - processor and
64k RAM each. I suspect the 2901s are microcoded 'glue logic' to support the
emulation of disk and peripherals. It's going to be fun to see if I can
reverse-engineer this to the point that I can load and run code on the Z80s! -- Ian

I have several non-DEC Q-Bus cards with MC68000 and a non-DEC Q-Bus
machine with MC68020 ;-))

Don't forget the 8008 (no typo there) on the KY11-LB, the
"programmers' front panel" control board for the PDP-11/04 and 11/34.
I don't have one in front of me, but isn't there an 80186 on the TQK50?

If memory serves, a lot of the EIDE drives have 80186 on the
