  A 50pin cable goes to some sort of Plessey converter,
another 50pin cable from the converter to the cipher drive.

  Is this a RK03 or RK05 pack ? 
AFAIK, an RK03 pack and an RK05 pack are completely interchangeable
(someone please correct me if I'm wrong), and certainly have the same
capacity and layout.  The drives are different; RK03 drives were made
by someone else (Diablo, IIRC) and rebadged by DEC, whereas the RK05
drives were actually made by DEC, and have a faster access time.

If it helps, that Plessey part number is an RK05 controller.
