They are indeed different. V7m is based on 7th edition A&T UNIX,
whereas Ultrix was based in BSD.
Ultrix32 was based on 4BSD, but Ultrix-11 is very definitely v7m rebranded.
Ultrix--11 2.0 did pull in some improvements from 2.9BSD, System III and
System V, at least according to the SPD. Ultrix-11 3.0 pulled in networking
I thought V7M and Ultrix were entirely diferent
and unrelated things.
At least on the Pro, DEC released a betal version of the one (which I
tried when
it came out) and then canceled it and replaced it by a release
of the other. I forgot which came first, other than that the beta was
really clunky. As in, a "vi" that didn't do real screen updates...
