Hey Birt!'s video: Dodgy Bodgy Fixing up a TRS-80 Model 102 with a few questionable vintage upgrades

Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://pcbway.com/g/m3hn11 In this video we take a look at a Tandy/TRS-80 Model 102 with a few questionable vintage upgrades. No doubt someone did the best they could back in the day but they did not age well. We’ll revert these mods to more of a factory condition and then get led down the primrose path when testing. Will we get this poor little T102 working again?
