Exactly what it says on the tin. Lots of useful historical information here; I came looking for details about MacHack.

From the earliest ones to the present. It's nice to see that people are now making replacement CPU boards for the older systems so you can use a more modern chess engine...

Stretch-ing Is Great Exercise: It Gets You in Shape to Win - IEEE Journals & Magazine
Fred Brooks on the IBM Stretch project, which pioneered pipelining, 8-byte bytes, multihead hard disks, and various other things we take for granted today. I particularly liked this bit about ECC memory: "The contract required that Stretch run for a month with better than 90% availability. The machine chugged along great and was hovering right above the 90% line when one bit driver, or else one sense amplifier, failed completely! For the rest of the acceptance test, the IBM team just ran it the way it was. There was not time to stop and fix it; stopping would have ruined the statistics. So the Stretch ran along to the end of the month single-error correcting every memory access from that box."

The terms are surprisingly old -- there's a 1963 paper with a diagram that's pretty much what's on my CMP202 slides.
