I tried a MicroVAX II in this backplane earlier and it...errr started to
smoke and the little display panel just said F.

Smoked the uVAX? That's a bad sign. I would otherwise have guessed that maybe your memory card is not actually strapped to address 0 when you look at all 22 bits?


Yeah!   It smoked the   VAX II! It could've been user error...but how the hell could I plug the breakout in wrong and have it smoke?!

Starting to think the backplane mayyyyy be wonky.
