Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.com/g/m3hn11
In this video we refurbish a TRS-80 Model 2 Keytronic ‘foam and foil’ keyboard. After learning how to identify the type of keyboard we have a good general cleaning done and a new set of foil/foam pads are installed. We then use a simple BASIC program to test all the keys. Will we get all the keys functioning once more? Join us and find out.
