In this video I go through the steps to fix a broken IBM Selectric Touch Keyboard from 1993 - also known as the IBM M2 Buckling Spring Keyboard.
Takes a little bit of soldering and 3 cents worth of components.
We also explore how wrong ChatGPT is about the chip inside this keyboard.

When I dissembled mine a couples of years ago I think I managed to brake one of the stabilizers on the spacebar. As those is also made of brittle plastic.
Think it can be good to mention that.
Thanks for a good video!

Thank you. Yes, it's not a very durable design. Same for most other larger keys - they really should've put a metal bracket to hold them but I guess it's another cost cutting measure.

Would this count as a mechnical keyboard?

[@AndersNielsenAA]

Good question. It has very distinct spring mechanism providing the switching.. but on the other hand it’s still a membrane keyboard. Both and neither I guess.

@@AndersNielsenAA Model Ms used a membrane too and folks would usually consider that mechanical (due to the buckling spring). I'd consider it mechanical.

[@AndersNielsenAA]

@@colinstu Usually the distinction is made between individual switches vs a membrane but it doesn’t really make much sense as a measure of “quality”.
You can find plenty of horrible mechanical switches and some great rubber dome keyboards too - I can’t handle 20 minutes of typing on a C64 keyboard no matter how “mechanical” it is ⌨️ 😆

I love mechanical keyboards and I'm a big fan of the old Model M. I was surprised to find out they had membranes under the buckling springs. I feel like a Coca-Cola fanatic who finds out they've been drinking Pepsi all this time without realising. All I can say is they _feel_ mechanical. I guess that's the main thing, right?
