It does. Running Ultrix DECwindows/Motif is almost acceptable, while Motif
is really slow under VMS. If you really want to push it you can run Ultrix
in the 4MB of onboard RAM on the VS3100. The box will boot multiuser and
you can login to DECwindows Motif. I did this already many years ago. The
reason nobody ran Ultrix on VAX is best symbolized by the DECstation 3100
IMHO. Cheaper than the VAXstation 3100 and 3 times as fast.
What I wanted to say is that it's not a fair comparison. People who bought
a VAXstation 4000/90 didn't buy it because it was fast. They bought it
because they needed VMS.
