An existing C compiler made it possible without too much effort. The
UNIX
source was available to Universities by then. I also developed Mini-UNIX for the PDP11/10=C2=A0 (also no memory protection) in the 1976 timeframe. This source code was also made available to Universities, but the source code for LSX was not.

Peter Weiner, the founder of INTERACTIVE Systems Corp.(ISC) in June
1977,
the first commercial company to license UNIX source from Western
Electric for $20,000. Binary licenses were available at the same time.
I joined ISC in May of 1978 when ISC was the first company to offer
UNIX support services to third parties. There was never any talk about
licensing=C2=A0 UNIX source code from Western Electric (WE) from the foundi= ng
of ISC to when the Intel 8086 micro became available in 1981.
DEC never really targeted the PC market with the LSI-11 micro,
and WE never made it easy to license binary copies of the UNIX
source code, So LSX never really caught on in the commercial market.
ISC was in the business of porting the UNIX source code to other
computers, micro to mainframe, as new computer architectures
were developed.

As the author of LSX an= d MiniUnix, are you aware of anybody porting
them to another non = PDP-11 architecture? ISC didn't do that at all, but
maybe you= heard of something through the years?
