(that is the
display which connected to 8/L's at Carleton college; they
had a great extension to FOCAL called COLPAC which would plot to the
display and do a vector font. They also had a joystick straight out
of "lost in space" - a large ball with stick and a "button" bar at
the
top.)
The one shown on page 1-3 of the below manual?

yes, that's exactly it. as I recall the "button" was bright orange and
the "stick" was silver.
the colpac "snowball" game was killer. it still makes me laugh. I may
have to recreate it just for yucks.
That display produced nice sharp green lines. it was nice to look at.
I remember once someone rigged up an 8mm camera and somehow had it
grabbing one frame at a time with some sort of electromechanical stutter
release. My guess is they made a movie, but I never saw the result. I
bet it was great...
