In the latest edition of Jack Ganssle's Embedded Muse newsletter, he mentions an the embedded systems timeline on Embedded.com. While the title of the article is "Milestones in embedded system design", this is really more of a general timeline of the history of computing, touching on the hardware and software innovations that have produced modern computing systems.
There's the obligatory picture of the first bug, plus a couple of gems - including a picture of one of the first Apple computers, complete with hand-made wooden keyboard case. It's not nearly as attractive as the steampunk keyboard (or anything else, for that matter) out of the Steampunk Workshop, but it represents a bit of history that I'd previously not encountered.
All in all, an interesting distraction for a few minutes, and one that makes me want to re-read something like Kidder's The Soul of a New Machine.
