I hauled the DEC + friends boards home earlier which I
mentioned finding on
the list last week.
The "unknown" board I'd noted down as M7961 is actually M7951, which
Google
suggests is a DUV11 interface board (whatever one of those may be ;-)
The board with the 128 mmc3764 ICs on it has what I think is a National
Semiconductor logo on it. Google's no help in IDing the 3764, but I'm
guessing it's a 64kx1 DRAM or related.
Next up we have the Emulex boards - all "FH" ("full height", 4 bus
connectors) or "HH" ("half height", 2 bus connectors):
TU0310401, FH, 2x50-pin headers on outer edge.
SU0210401, FH, 1x60-pin and 2x26-pin headers on outer edge.
CU0210402, FH, 2x50 pin and 1x16-pin headers on outer edge.
QD3310401, HH, 1x60-pin on outer edge and 2x26-pin
headers just inboard.
QD33 = QBus MSCP compatible SMD-E disk controller

QD2110402, HH, 2x20-pin headers on outer edge, then a
34-pin and 10-pin
header just inboard.
QD21 = QBus MSCP compatible ESDI disk controller
