Does anyone have any information on a Plessy board model number PM DCV51?
It appears to be a disk controller one 34 pin connector and four 20 pin
connectors. It has plastic handles on the ends like a QBUS board. (I
suppose it could also be a quad wide unibus board but I don't think so.)
Markings on one of the chips is:
P/N 706131-1001B
S/N S-179 1/5/87
Model PM DCV51 (could be OCV51 the D and O are hard to tell)
There is a NEC D7261AD chip on the top, an uncovered EPROM (worrisome),
several PALs and a large chip (68pin DIP) labelled AM29x305
Anyone?
