This is like the twilight zone. I _never_ though I would work on another
Q-bus board!

Anyway, after designing 5 Q-bus boards for Avalon (and 4 Unibus!) I've
got those specs memorized. For the promise of a beer at some future
conference I might be able to unarchive them from my brain. It was not
a very complex bus, at all.

DEC used to print the spec in the really old peripherals handbooks.
IIRC it also appeared in a processor handbook or two. I imagine
Avalon's old designs aren't exactly top secret and confidential any
more. I could put a Q-bus page up for ftp as a .ps file, possibly, that
would at least get you the pin-out.
