Unix Seventh Edition Manual

So there must have been a sixth edition....

Was trying to remember the Bell Labs followon to Unix...thinking it was PLAN (6) maybe.

The Unix Seventh Edition is copyrighted in 1979
it was most likely UnixTSS 7 (1979)

My Bell Labs Unix System V R2 manual
is dated December 1983.

I worked at Bell Labs in Denver from 1982 - 1990
We used System V Release 2.
or BSD 4.3 or Amdahl UTS.

Some Super sub-sets of Unix
were used in Switches up through COs
