<A couple of very custom DEC chips that form the VAX CPU IIRC.
The Microvax CPU is one chip. The DMA is the other. However neither is
a 78032 Microvax CPU. Maybe a later one.

Determins if the machine will stay in diagnostic mode, Inquire what language
to use (13 possible) and run straight through to trying to boot. If there
is a boot device it will try it, if not you get an error message and the
>>> prompt.

sounds about right.

DELQA eithernet, the better one to have.

RQDX3 controller, drive is likely Micropolus 1325(70mb) or
Maxtor2190(159mb).
