The console commands for the MicroVAX II are a subset of the commands
available for 3100, the "KA630-AA CPU Module Users Guide" mentiones:
- "X" (binary load and unload)
- "BOOT"
- "CONTINUE"
- "DEPOSIT"
- "EXAMINE"
- "FIND"
- "INITIALIZE"
- "HALT"
- "REPEAT"
- "START" (same as DEP into PC and CONT)
- "TEST" (valid args are 3..7 and B)
- "UNJAM"
There's no way to get information about installed devices or
memory-size from the console commands directly.

In prinicple it's possible to netboot a MicroVAX II, but NetBSD's current
netboot/mopboot binary doesn't hold a standalone driver for the DEQNA.
The netboot/mopboot image get's transferred via mop without problems,
but then then problems start, since this image doesn't know how to
use the DEQNA for the next boot-phase.
In other words: Nobody has written this standalone qe-driver yet and
without this driver it won't work.

At the moment i see two options:
- write a standalone qe-driver ;-)
- attach some spare 5.25" floppy drive from a PC to your MicroVAX II and
use the RX33-images to boot the machine.
