Imperfections, but at least we get a general idea. ;)
Really? I bet there is a factor of 2 at least in that lot when you put them together? (Depending on what you are running) Remember the reason you are scrabbling around for this ancient machine is to answer a question along the lines of 'is my program useable on a .....' ? Also you want to make sure you haven't made an assumption about an actual feature (you left a cmov in somewhere? You assumed AGP? LBA block addressing etc).
