I guess another thing that would be useful would be the initial starting
point of the serial numbers for each computer. I find by looking at the
date code on the ICs, I can get *some* idea of when a machine was
actually built. Of course, that assumes that the chips were used
shortly after they were made, and I generally look at a variety of chips
to find the latest date code. I hadn't thought of ECO's; that sounds
like a good idea. Thanks!
