Information on Old Computers?

sj12fn asks: "I am working on a Computer Family Tree. It's going to include every OS ever made, every piece of hardware ever produced, every computer language ever written, and every standard ever published. What I'm here to ask is if anyone out there in the Slashdot crew has any useful info for us to use." That's a pretty tall order, but it sounds like a worthwhile project, if only from a historic point of view. It looks like the recent question on the first computer OS will get more use than expected.
