INTERACTIVE Systems Corp. (ISC) also ported a UNIX system to an
early VAX 750 computer running DEC's VMS operating system
starting in mid- 1978. ISC was in the business of porting the
UNIX operating system to many different computer hardware
architectures, mini-computers to mainframes, but the first
complete UNIX system port was actually done to the DEC VMS
system. We delivered the first UNIX on VMS system to a customer
in the Fall of 1979.  Many of these systems were delivered to
customers in North America as well as in Europe well into
the mid-1980's.
