Xenix didn't support VM until much later in its life; I
ran Xenix for the x86 on a 10MB HD original PC XT system.
Everything had to compile and run in Small model.  The
286 supported both Small and Medium model, which gave you
access to more than 64k of data space at once... man, was
that living!  8-)

Xenix also ran on Sun 3 hardware, but was never released
on it outside Microsoft's walls, and ran on 68000 hardware
from Radio Shack: the Tandy 6000.  It used the two CPU
fault restart trick... 8-)
