the early days of AutoCAD, we attempted to support some truly awful
hardware in the hopes that its manufacturers would help us promote
AutoCAD. To give you a flavour of some of the things we tried, I'm
including a description of the attempt to get AutoCAD-80 running on
the DataType 150, an RS-232 graphics terminal. The DataType 150 was
neither the best nor the worst device we attempted to support. It
shared with the best and the worst one common attribute: we never sold
a single AutoCAD configured for it.
