AFAIK it has straight Q/CD Backplane like
in the BA21x enclosures.
I'm assuming I can't stick something like a
4000-300 boardset in it
No. The 4k200 / KA 660 was the last Q/CD VAX CPU. The later
4k[34567]00
CPUs are using a special connector to the backplane. It caries the
QBus, a DSSI bus and the memory interconnect. You need a BA440 for this
CPUs.
