There are no OS dependencies that I am aware of, beyond how much
physical RAM you have to stuff into the box. We ran 4.0BSD and 4.1BSD
(and VMS 3.4, I think) on an 11/750 w/2MB. When our leased system
went away, I added the extra memory line to the backplane and took
that same 11/750 to 8MB, where it still remains. On that machine, we
ran VMS 4.x and various versions oUltrix.

There is. Finding it might be tricky, though, and I forget what
versions run on the 11/750, but ISTR we started with Ultrix 1.1
sometime around 1988 (and it wasn't particularly new then).

Unless you are a dedicated DEC masochist, I can recommend exploring
4.3BSD-Tahoe vs Ultrix.
But for me, even though we did run both BSD and VMS back in the day,
if I were going to pay to power a Unibus VAX, I'd set it up to run VMS
and leave BSD to more generic hardware.
