Agreed. The 411x machines had much more local processing and were
My thought was not to make a statement about the power of the 4105
relative to other members of the period Tektronix product line. My
thinking was that this meager amount (by today's standards) of ability
in a Tektronix 4105 was sufficient for the CAD market at the time. I
could be wrong there too :-). In 1986 I wasn't doing market analysis
of product requirements for CAD. However, I was reading the print
eddition of EE Times (man, what a great EE paper for the 80s, I wonder
if any collection of printed issues survives?). They regularly talked
about product announcements, particularly in the realm of CAD tools.
Still, it feels like simple 2D raster displays is what the CAD
programs were talking to at the time. I'm not sure when workstation
based CAD started taking over from terminal based CAD, but I have a
feeling that by 1990 it was firmly in the hands of workstations.
Another decade later and it feels that CAD was firmly in the hands of
Al, is anyone compiling CAD software history for the CHM?
