AEHR / Computest CPM computer?

Dick,

   It uses a large card in the bottom for the CPU and support circuitry.
There's several cables that come off of it and connect to various other
areas (power supply, monitor, backplane, etc). Above that is a backplane
with about ten or twelve sockets similar to those used in PCs. The cards in
it look very similar to PC cards but they don't have the metal bracket on
the back. Their connectors just stick through the back of the case and
there's one screw located below each connector.

  If that's not clear enough I can take a photo and post it for you.
