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
to verify this.

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:

There are tools that will convert to/from Bob's Simulator format as needed.

How do I open a .tap file in the .zip file for mini-unix?
Also, do you have a date for this snapshot. A date would be
very useful for "product comparisons" at that date.
