I was working on the MicroVAX-II support, just slacked off for a while.
I've got almost the exact same configuration (KA630, 9MB, dual RD54 on
RQDX3, etc. For the record, your disk drive is an RD54 and the RQDX3
supports it, maybe even in the same box (if you've got a BA123, the big
box).  It took some extra cables to run 2 RD54s and a TK50 in my little
BA23 box.

Last thing I was doing was working on a standalone boot program, since
ultrix's boot isn't usable.  Ragge said something about a boot
program too -- do you have a standalone library and/or device drivers?
I scrounged some standalone code from 4.4bsd.
Now I've got a ka630 manual  and can figure out how to set up a boot block.
