OK, that does look like the official Mini-UNIX release from
Bell Labs in 1979. I'd have to look at the files in the .tap file

Note the name Mini-UNIX was also used by Andrew Tanenbaum
for the system he developed at Vrije Universiteit in Amsterdam
much later in 1987 independent of the Mini-UNIX that I developed
at Bell Labs in the mid 1970's. See here:
