In the mid-eighties, I was making the transition from CADDS 4x to
DEC-Euclid. By late eighties, from DEC-Euclid to CATIA. Busy busy time
in the CAD world.

In the mid-1980's I lived in Lowell, MA and my
then wife (and briefly,
myself) worked for a circuit board design company. Their primary CAD system
was a PDP-11 based system from a company called, I believe, Telesys. It was
a very good system from my recollection; it used a dual-display concept
which was very efficient and had extremely good performance.
The actual design consoles looked a lot like arcade video game consoles.
There was a small monochrome CRT on the lower panel which displayed menus
which one used a light pen to navigate through, and which was also used for
drawing. One saw the results in "realtime" on the larger colour screen, all
very sharp.
Does anyone here have any more info on these. I do recall this being a
*very* good system, but I can't find mention in my web searches.
Thanks,
