[TUHS] Early X (or W?) sighting from 1984

[Lars Brinkhoff]

I found this 1984 video about MIT's Project Athena.  A few VAXstation
100 are visible running some demos in a windowing system.  Nothing
exciting unfortunately, just a few seconds and no details visible.

Since X was started in 1984, it could be a very early version we see
here.  I asked Jim Gettys, and he suggested it could also be W since it
was apparently used before X in Project Athena.

I checked the xdemo director in X10R3 (earliest available so far) for a
match against the circle demo, but all samples are written in CLU...
