I heard at the time, that the Apple Laserwriter was the "most powerful" 
machine that they made, and that certain people were connecting terminals

Postscript, but didn't have a Laserwriter.  It was a stack based language, 
with similarities to Forth.   I suspect that the "terminals" were actually 
terminal emulation in whichever machines were currently connected anyway.

I made a company logo that was outline letters with a fill of lines 
radiating from a point (think about Moire pattern artifacts when pushing 
the resolution limits).  Then I found that the "Freedom Of Press" 
Postscript emulation of the commercial large format printer was too slow,
