Part II of my TRS-80 Model 16B restoration. This time, I'm focused on the Keytronic keyboard: I test it out using my TRS-80 Model 12. I then clean it up and replace the capacitive foam pads. Afterwards, we verify operation and reassemble it. Unlike previous videos, I did not leave the time lapse sequences fully intact. This was done to keep the video down to a reasonable length.
You can find the replacement capacitive foam pads for Keytronic keyboards at TexElec: texelec.com/product/foam-capacitive-pads-keytronic
