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: http://www.ebay.com/itm/151768446404
