Yep, it's in a BA23 with a ridiculously dense Q-Bus. I considered installing
the KZQSA from the 4000 in the 3200, but the edge connectors won't fit even
after removing the panel, plus I read in the list archives that the 3200
won't boot from it. :^(
I just tried an M5976 KZQSA with an M7620 KA650, an M7624 KA640, and
an M7625 KA655 CPU. None of them would recognize the M5976 KZQSA as a
boot device.
I think you need at least an M7626 KA660 CPU or better to recognize a
SCSI CD-ROM attached to a M5976 KZQSA as a boot device, where it
should normally appear as DKA0.
The VAX 4000/200 M7626 KA660 CPU is the last VAX CPU which plugs
directly into a Q-Bus slot and you could in theory use it in a BA23
chassis, but wiring up the on board interfaces would take some work
without the cab kit for that. I've only seen one of those go buy on
eBay:
