Yep, I was thinking that too. Wish I'd tried to bring the whole machine
home now!
I wonder if I can power the board here... far as I know it's standard
VME bus and probably doesn't need any strange voltages (just lots of
current - there's a huge amount of silicon on the board).
Only question is whether it'll get upset not being connected to a
backplane (which would contain a handful of pull-up / pull-down
resistors etc.).
Other than the bus issue it's a totally self-contained board, so I'd be
able to fault-find on it under powered conditions on the bench.
