[Simh] Ultrix 1.0

[Henry Bent]

I had success booting the Unix Archive's floppy distribution of Ultrix 1.0
on the MicroVAX 1 simulator.  It appears that the distribution there was
only meant for a dual-RX50 MicroVAX 1 with an RD drive, and will not boot
on any other machine.  RQ0 needs to be an RD51 or RD52, and RQ1 and RQ2
need to be RX50s.  TTI and TTO need to be 7 bit.  To boot the installer,
put 32m-1.0-bin/01 on RQ1 and 32m-1.0-bin/02 on RQ2.  The install goes
cleanly, albeit with quite a bit of disk swapping - the installation disk
set is 13 floppies.

The QVSS is supported and will display some output on boot.  I haven't yet
looked into what is needed to use it as the console (if that's possible?).

The kernel seems to support what I assume is the DEQNA - it has references
to a qe device - but I can't figure out how to get it recognized.
Unfortunately there are no kernel config files in the distribution, so I
have no idea if the stock kernel is expecting the controller at a
non-standard address.  Any help with this would be greatly appreciated,
