We were a beta test site for NOS/VE and the hardware (Cyber 180?). CDC
sent the machine and a software support engineer to help us do something
with it. My one recollection was that the command language was horribly
awkward, but I didn't spend much time on the system.
I know there are some manuals for NOS/VE on bitsavers, but I wonder if
any of the software still exists?

I came to it all a bit later. I do recall the CDC salesthing saying
something like "oh, you guys have some Unix around here? Have we got
something for you!". And the systems guys brought up NOS/VE on the last
CDC machines we ever bought.

Please...I'm trying very hard not to remember them (or NOS...worse,
NOS/VE).
I left CDC at around the time that SCOPE 3.4 was being renamed NOS BE
and KRONOS was becoming NOS. I remember attending a design meeting for
the pager in what was to become NOS/VE. I asked the presenter if he'd
conferred with any of the virtual memory pager talent that CDC had
in-house. Blank stare. I informed him that the STAR-100 people had
lived in that particular hell since about 1969--and that demand paging
was not the way to run a shop. STAR had long-since switched to a
working set algorithm.
Even that wasn't enough. If one selected a large (65 KW) page size and
set up certain vector instructions so that addresses crossed page
boundaries, it was impossible to get the required pages into memory all
at once.
The system just sat there and thrashed....
