ULTRIX and VMS

Regarding ULTRIX and VMS,

ULTRIX was NOT "developed" by DEC wizards.  ULTRIX is a version of
BSD 4.2 UNIX which is being supported and sold commercially by DEC.
DEC is undoubtedly working on supporting their newer hardware and
probably some DECNET compatability.

VMS and the VAX architecture were developed together as one product.
Therefore VMS and the VAX hardware are optimized for each other.
UNIX was ported from PDP-11s to the VAX.  U.C. Berkeley then added
paging (plus several other changes).

Both UNIX and VMS have their strengths and weaknesses depending
on what you are trying to do (UNIX usually given the edge in a
software development or documentation environment).  As far as
the number of user a machine supports, that depends far more on
the applications being run on the machine rather then whether it's
UNIX or VMS.
