> German Utility Patent 1,279,693

This one's pretty amazing to see, given how close it is in appearance to the Ergodox and other "glove keyboards" (rather, the other way around—they all resemble IBM's patent!).

> British Utility Patent 1,363,777 (GB1363777A)

While the buckling spring switches used in the Model M (or, for those with more rarified tastes, Model F) are rightly lauded, the beamspring is less well-known. The individual modules are absolutely massive as far as keyswitches go, but they feel wonderful to type on. They were designed to evoke the Selectric so as to be familiar to new users, and some models, such as the 3278, even included a solenoid that would click with each keypress. They also featured doubleshot keycaps and were absolute bricks that make the Model M seem a featherweight by comparison.

I wish I had had this 5 years ago. The early laptops are worth scrolling down for. Really amazing resource.

Anybody aware of similar resources for other early computer patents for Apple, Commodore, Tandy etc? Or another IBM resource specifically covering more than just keyboards ie the 5150, PC Jr etc?

Eliot Noyes Sighting!

One of the GOATS. Thanks for posting - there's so much awesome stuff here beyond his designs, but as an architect I gotta rep my man.
