Model 4 Membrane Keyboard Repair Document

[Wildgen]

I recently acquired a TRS-80 Model 4GA that wound up having some issues with some of the keys.

Despite being told they were almost irreparable, using info/advice on some 10 year old posts I went ahead and took it apart, cleaned it, and put it back together with successful results.

I wanted to share this procedure with the community so I write up a PDF that is attached.

I hope everyone finds this useful.
Enjoy!

Hi and welcome to the forums

Thanks for sharing your experience and taking the time to document it. I have one of these machines in storage and imagine I will have to do this one day
