Of course, I'm running AutoCad 1.21 here...

Let me guess, the RAM is above board. I have forgotten how really advanced Autocad was at that point in it's life. Our first workstation was a Tandy 1000 with 2 Meg above board RAM, a 28Meg hard drive and an external 10" Bernoulli drive for drawing storage. We quickly upgraded, settling on Autocad Ver. 3.21 for several years.
When considering CAD computers remember that CAD is video intensive so that computers that share system RAM for video will bog down. Depending on the CAD platform you are using, they usually spec minimum video card and video RAM. Follow the manufacturer recommendations or forever be waiting for numbers to crunch in the video RAM, especially during zooms and 3D views.
