Are you old enough to remember the Scitex Response 280?
In the picture you can see the CAD Input Digitization System, based on a color workstation and the large format drum-based Super Scanner. The system was designed to scan technical drawings in raster and feed them to a CAD system as vector data with certain amount of intelligence added to it.
The picture was sent to us by Shmuel Dekel (See ExScite Nostalgia section posting from: 12/11/2003 6:27:51 PM).
