A simple IBM- a Tandy 3830, 386 with 4mb RAM is all it took to get this off the ground. Of course, the entire chapter on methodology was written on it. With the water spill on the computer, well--I can't get to it. So, for any detail on methodology, we go here instead. Oh, and the dog is a good consultant for taking breaks (he wasn't the water-spiller though . . . )
