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)
cheers

Better check that!
"normal" 5.25" floppy is 34 pin. 40 pin implementations, such as some
PS/2s put power on those other 6 pins.
34 to 50 pin cabling information is readily available.

Aha - no, I merely meant that the cable between the drives (8") and the back
of the disk cabinet is *probably* straight-through. How it's wired between the
40 pin connector on the Exormacs itself and the 50 pin connector on the drive
cab is a complete unknown (to us).
Hopefully someone knows; failing that it's *probably* a recognised FDC in the
system unit and so will be traceable. I'll do some more digging inside the
machine if needs be, but I'm sure someone on here has mentioned that they have
an Exormacs machine in the past...
Of course there's a question of how usable it may be given the absence of any
media; I'm not sure how much was in ROM on these machines and how much was
booted from floppy.
