I took a course in Autocad back in the early 80s, I just loved it's precision. I aced the course and found a pirated copy (it was several thousand smackers back then) and I was a drawing fool. I still can't afford it and wouldn't even if I could because it's scandalous. I have a little version from autodesk, QuickCad, but it's old and they don't make it anymore. I've found that turbocad 15 - 17 is a pretty good replacement. Ever since I took the course I've just been crazy about CAD drawing ever since. Back then I has an old XT, I scraped up about $200 to buy an 8087 math coprocessor to run it. My ex wife was really upset, but then i actually used it for work.

Never used anything but OrCAD GMS. lol

Man, I remember the days of having to get a separate math co-processor and then I remember when they started to combine both on the same chip. Man those were the days. Only had to fiddle a few times with Autocad (to create searcheable PDFs of Circuit boards that were laid out in Autocad as I recall) but never used it to draw. I believe there is an open source cad program, but never used that one either (just not in to CAD programs I guess).

Back in the 80s, Technicad was the big kahuna, until AutoCAD rolled out. It was rather clunky, I thought it was easier to draw by hand. AutoCAD changed my mind on that, using the plotter.

Lyle, yes, I originally had an SX machine but couldn't run AutoCAD on it, until I installed the math-coprocessor. I'm trying to remember what my actual processing speed was (it's been so long ago) 33mHz? It wasn't a lot, lol.
