My earliest recollection, and earliest contact with the department of
Computer Science, is from the spring of 1978, when I came for an open house.
I saw the Norpak graphics system as well as some other demos, which I later
learned made use of the PDP 11/45, behind the scenes, running UNIX Sixth
By the time I started working (part-time) for the department, late in my
first year of study, in 1980, the PDP 11/45 was still running UNIX 6ed.
One of the first tasks that my brother and I undertook, when we were put in
charge of administering that machine a year later (summer of 1981), was
upgrading to UNIX 7ed, which had been released in 1979, and which had
been purchased and was (sadly) sitting on the shelf for almost two years.
I have no knowledge of specifics pre-1978, but I'm quite sure the PDP had
been around for a few years already, so it's quite possible that UNIX 6th
edition (released May 1975*) had been purchased for it, or in anticipation
of using it at a later date.
According to Bill Reid:

And one of my first tasks after going to work full-time for the department,
in the fall of 1989, was to get our systems Internet-ready.

I'm not _that_ old! ;)

Yes, they did, but I'm not sure how far back the "early days" go in this
