I've been trying to track down online documentation (manual, engineering
drawings) for this Quad Unibus card, a controller for the RX50. No luck at
all. Nada :-<. Just some references in RSX/RSTS/Ultrix marketing
documents.
Does anyone have, or know where such documentation can be found?
Also, does anyone have (or knows someone who has) a spare/loose M7522 that
they'd be willing to part with?
Thanks!
