All, I'm looking for images of the cat device as

times in the 7th edition manual, see e.g. TROFF(1)and CAT(4).
From what I gathered during my digs is that it should look like a
GSI 8400, but that didn't help. Anyone here who can help me find out
what these machines looked like? A picture would be the best, but
information on what to look for in images of unnamed typesetters will
do as well.
I really have to dive deep in some old papers where I used to have some
documentation including the the way the light path worked (fiber optic
cable, the DBL lens). One of these days I will try. The wikipedia
description <http://en.wikipedia.org/wiki/CAT_(phototypesetter)> seems
pretty accurate although I have never seen the beast myself.
