I was on the research staff at SRC from 1987 until 2001, and I had a
Firefly as my main computer for several years until we replaced them with
MIPS and Alpha based machines.
Mine originally had two MicroVAX II 2-cpu cards and a cpu+I/O card. Later
the two 2-cpu cards were replaced with 2-cpu CVAX

Did you get an actual Firefly (research) board, or a prduction VAXstation
3520/3540 board? I don't think you're likely to find schematics or pinouts
for either, but it's not impossible to find 3520/3540 stuff, while I've
never before heard of anyone encountering any actual Firefly boards in the

Impressive. You might be able to get some information from DEC research lab
reports. Some SRC reports describe aspects of Firefly, but probably not the
stuff you need. It may be that some of the creators are still reachable, in
which case you might get first hand data.

Against my better judgement, I obtained a DEC SRC Firefly dual processor
card. If i read this* correctly, then this card is interfaced to the
shared memory bus (MBUS) as opposed to the QBUS (the card uses a Q bus
format).
I realize it's probably hopeless, but I'll ask anyway: Are
