Hi everyone,

I am collecting old UNIX license agreements to be able to establish the dates of
early installations. So far, I have licenses for Regents of the University of
California (1973-12-01), KU Nijmegen (1974-12-01), University of Manitoba
(1975-02-01), and KU Leuven (1977-09-01), as well as 1982 license specimens
found by segaloco and others from the ‘80s.

They did not track license dates at Bell Labs, so this is the next-best way to
determine that. Before we found documentation on the receipt of the Utah UNIX V4
tape, I narrowed down when we could have received it from tracking down software
agreements for institutions around Utah in Ken’s list of licensees. It’s also
interesting to see the evolution of licenses.

If you have UNIX software agreements that are public or I could publish, please
send them my way! I’m also looking for first-hand accounts of such dates.
