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?

Not cheap but I think he got the patent, tooling, and all.

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.

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 remember typing on a Model M as a kid. My fingers pushing the empty spaces between CTRL and ALT, where on newer keyboards, an OS meta now lives.

I remember writing Basic. Then Turbo Pascal. Full of curiosity and wonder.

The IBM authentic keyboards have a badge on the back with the year and month of manufacture. Most of these keyboards are older than my co-workers. Many still function correctly.

They're a joy to use.
