I need some help identifing some of the boards that I
pulled out of Paxtons
yesterday:
M7904 - Not listed in the Field Guide
Hex-Height
40-pin ribbon cable sticking out the side
This is one of the five boards (M7900-M7904) in the RK06 system
unit. This particular board contains the drivers for the actual
drive interface.

From the part number, I'd say it was a DLV11-*
clone. Does it have
one 40-pin connector or 4 10-pin connectors or ? MSI-11

faded to read
Andromeda has made a lot over the years, but from the part number I'll
hazard a guess that this is a Q-bus memory board. If you could mention
any obvious chips, arrays, or connectors maybe a better guess will be
upcoming. A two board set
from Plessey Peripheral Systems connected via a 50-pin
ribbon cable. The top board (P/N 703580) has 8 LEDs and a 10-pin
connector. The bottom board (P/N 703570) has 4 26-pin connectors and a
roughly 66-pin connector (not sure its exact size). The only thing I can
think of is some kind of drive controller.
If the big connector is 60-pins, then it's the Plessey 4 SMD drive
controller. Plessey also made some other two-board controller sets
for Pertec unformatted tapes, but this sounds more like their SMD
controller.
