Stretch-ing Is Great Exercise: It Gets You in Shape to Win - IEEE Journals & Magazine edit / delete

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."

rcornwell/ctss: CTSS source and binaries edit / delete

Tidy copy of the CTSS code. I was struck by how modern this is in several ways -- the MAD language it's written in is remarkably nice for the timeframe.

Retrograde Station edit / delete

A large collection of early PC "booter" games, mostly converted to be hard-disk installable. Useful if you're after period-appropriate software for an XT or AT. (Although this hostname appears to be pointing at a different site today, for some reason...)
