PDP11 Plessey disk drive info needed

Hi all,

I would like to connect a Plessey disk drive to a PDP11 RK11-D controller.

The drive has a fixed platter and a removable platter, compatible to RK05 I
believe, and these numbers on it:
Plessey 3468-0231
PMDD/11B
700540-200217D

It has a 42 pin MRA 42 S mating connector, and same with a terminator. I
believe the 42 pin should be a Drive Bus, to be connected with standard
Unibus cable to controller slot 2A/2B.

Question: Would anyone have a maintenance manual for the Plessey drive
available ? Short of that, maybe the pinout of the connector, so that I can
make the cable ?

Of course, reverse engineering of the disk electronics should reveal the
pinout/RK11 compatibility, but having the docs just would save a lot of work
and be more reassuring !

Thanks and regards
John G. Zabolitzky
