Lesson plan
Digigraphics
Digigraphics was one of the first graphical computer aided design systems to go on sale. Originally developed at Itek on the PDP-1 as EDM (Electronic Drafting Machine), the efforts were purchased by Control Data Corporation and ported to their machines, along with a new graphics terminal to support it. Systems cost almost $500,000 and supported only a few users at a time, so in spite of a number of advantages it was not cost competitive with traditional manual methods and only a few systems were sold.
