I won't dispute your age, or how many layers of pearl are on the seed
Larry, but MP unix was a thing long long ago.

I am pretty sure it was written up in BSTJ, and there was Pyramid by
1984/5 and an MP unix system otherwise running at Melbourne University
(Rob Elz) around 1988.

You might be ancient, but you weren't THAT ancient in the 1980s.
