Hi there. I just acquired a Twentieth Anniversary Mac. Previous owner says the N key is non-functional, so I'm planning to pop the key off and see what I can do to fix it. After a lot of searching, I can't find existing info on what type of mechanism is used under the keys on the TAM keyboard.

Has anyone ever disassembled a TAM keyboard? Hoping to figure out what type of mechanism is under the keys so I don't break anything when disassembling.

Oh, and if you've ever run into a non-functioning key on a TAM keyboard (or similar), please let me know if you have any tips/leads on how best to fix.

Thank you for any guidance you can offer...
