Jerome Fine replies:

Might it be possible to use the colour output when connected
to the TV? Now that would be an interesting appliance?

What hardware does your PRO350 have and what disk drives?
RX50? RD51?

Since PO/S is really based on RSX-11 (if I remember correctly),
your are already running RSX-11. RT-11 also runs on the PRO350,
but you must have an RX50 that allows RT-11 to boot. If
you have all the required files on the RX50 that runs on a normal
PDP-11, then for the RT11XM monitor, add (assuming they are missing):
PIX.SYS
DWX.SYS
DZX.SYS
If you then execute the command:
COPY/BOOT:DW DU0:RT11XM.SYS DU0:
(assuming I have not confused the hard drive device driver DZX.SYS
with the floppy device driver DWX.SYS). That RX50 can then be
booted on the PRO350. I am not sure which version of RT-11 was
first able to use the PRO350, but certainly by V5.03 of RT-11, it was
possible.

I don't know what VENIX is or how it works, but I get the
impression that VENIX was used on the PRO350 when
the PRO350 was used as the console device for the
VAX 780??????

Sincerely yours,
