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.

Where's the disagreement?
Eunice post-dated DEC's first Unix offering by several years. They
sold V7 and later V7M before rebranding it to Ultrix. Eunice was
4.1BSD (later 4.2 and 4.3) that Dr Kashtan grafted into VMS in ways
that... provoke strong feelings among reviewers... The TCP/IP stack
that was inside of Eunice would form the basis for Wollongong's TCP/IP
offerings on VMS... A more refined version, also done I think by
Kashtan, was marketed by TGV and there was always much rivalry between
the two companies...
Wollongong got its license because they were the marketing company
formed to market Dr. Miller's port to Interdata, and they later
branched out significantly because their license was so special... Or
at least that's the story they told customers and internally... I
never saw the original license to know...
