3) Qbus-like board, supposedly a CPU, handles made by
DEC, board is 4
slots wide, labelled "PCS" (is that PCS CADMUS?), has Motorola
MC68000L10, 4k SRAM (2*6116), 16k EPROM (2*2764), clock chip (MM58167),
battery. Between the handles, there are two 40-pin 3M connectors (Berg
style). The EPROMs have stickers saying
MINITOR MINITOR
R900.123 R900.123
E9 2.200LO E10 2.200HI
Without a picture, it's kinda hard to guess, but the 68000 was a common
chip to use in the 1980s for a VAX peripheral (we did it on the COMBOARD,
DEC did it with the DMB32, etc).
If there are 1488s and 1489s near the BERG connectors, it is probably
a protocol converter of some sort (like a COMBOARD or Simpact board).
Otherwise, if there are any other large chips, they might reveal what
this board did.
