I haven't personally looked into doing this in detail, so I can't give a
definitive answer, but your last question here makes alarm bells go off in my
head.
The M930 is designed to go in UNIBUS In/Out slots. These slots do have
different wiring from the A/B MUD slots. (For instance, UNIBUS In/Out slots
have _single_ pins assigned for BG4-7 and NPG, providing 'grant in' or 'grant
out' functionality, depending on if it's an In or Out slot. I don't recall
offhand what function/signal is on those pins in a MUD slot, but I'm pretty
sure it's not a grant!)
I would be fairly astonished if a device intended for a MUD slot would work
in a UNIBUS In/Out slot, and vice versa.
