Motorola Exormacs - disk cable

We've just acquired a Motorola Exormacs system, which is sadly without its 
floppy drive cable (40 pins on the Exormacs side, 50 on the 8" floppy unit 
(Exordrive III I believe).

I suspect the floppy side is just straight-through to the drives, but can 
anyone confirm that, and does anyone know the pinout on the system unit side 
of things?

Worst-case we'll have to reverse engineer it, but maybe someone knows (we've 
got no floppies for the system and no useful manuals unfortunately)
