I bought this Tandy 6000 computer system back in 2013. It’s the last model in the Tandy/TRS-80 model II/12/16/6000 series. It would not power up, and I began an on-again/off-again project of fixing its power supply spanning over several years while being distracted by all sorts of other shiny objects. I ended up temporarily (?) replacing its power supply with a modern generic power supply in 2018. This is a summary of what I did, in case it might inspire other owners of the Tandy/Radio Shack business computer system line.
