I started on ACAD in ver.2.1 with dual monitors (one color, one b/w) on a Radio Shack 8086 with 2 MB above board RAM (640k on the motherboard), two video cards and a 40 MB drive. We wrote drawings to two removable Bernoulli drives of 10MB each. I have used a digitizer all along and a custom tablet menu and overlays make fast work of drawing. My current tablet is a Calcomp/Summagraphics with 16 button cursor. I rewired the two center, top row buttons to be left click. Other buttons are common tasks like zoom, line, and custom menu entry.
R10 was a big improvement over 9.1 which allowed some 3D with Lisp routines only. Autodesk is upward compatable so most of the command line entry still works. There have been big improvements over the years as multiple commands were merged into single commands to make things go faster.
We had a pen plotter with only one holder. If you wanted multiple colors, you had to change pens. A C size plot of a complex schematid would take an hour or more. If you went to lunch and the pen clogged, you started all over again.
That book has a lot of useful info, I would keep it around for a reference.
