As I recall you plug in disk one and it works if you do B DUA0;
if you separately plug iun disk two (with its own cable etc.) it also boots as
DUA0.

As far as I can see this is hardware. The RA7x drives can either be told their
unit number by the OPC (the panel on the front) or they can have it
set by switches somewhere. I'm away from any manuals or real hardware
until Thursday but I'll try to check then. If (when :-) I forget,
you'll have to prompt me.

Yup. You need V5.3 or V5.7 or some such (see, I told you I wasn't near any real
hardware). What you have is an early vintage set of EPROMs that can only do
more or less what the MicroVAX II could do in terms of console commands. Later
on in the day they became much more friendly.

Well if 
	B XXXX
works then XXX was recognised as a device :-)
