I LOVE the beeper in those keyboards! So happy to see one loved and working with it’s machine. ❤️

Clean keycaps with denture tablets, move up to soap and water with a sponge if needed, flitz polish as a last resort (it will wear the caps down, other two are perfectly safe). Caps are doubleshot iirc so no risk of wearing off the legends.

Retrobrite at your own peril. I do not advise. That said, only ABS plastic goes yellow with age, so the same techniques for retrobriting will work on both caps and case.

Cleaning the spring with conventional rust removers is up to you but the springs will rust again so I say to leave the rust on to protect against future rust. Oiling the springs would help though.

I love to see old tech being loved and treasured. Cheers to this and may every old computer have such a loving home.

An anarchist group is authoritarian? What are you smoking.

Yes but antifa is anti fascist.

Calling antifa a terrorist organization because in another universe an organization sharing the name could be bad is like banning ice cream because it could be made out of maggots.

Op, please patent it so no other company can use it for the next 20 years

As a big keyboard nerd it is cool to hear about Alps in another context. They used to dominate the mechanical keyboard market too back in the late 80s.Thanks for sharing!
