D'oh!   my 1M RAM board was set to 18-bit mode, not 22-bit.

My SCSI controller seems to dislike it on 22-bit, though...

...is my backplane not 22-bit?!   I know very very little about it.

http://bitsavers.trailing-edge.com/pdf/clearpoint/Clearpoint_QRAM-22B_User_Information_Manual.pdf
is the RAM board,

http://bitsavers.trailing-edge.com/pdf/cmd/MAN-000420-000_CQD-420_May94.pdf
is my SCSI controller.\

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?
