In this video we take a look at a TRS-80 Model 200 which does not boot and has a strange symptom. This sort of symptom can lead one down the primrose path but luckily we find it is a simple fix and as a bonus we fix a bent AA battery contact as well.

01:07 – Strange symptom
02:10 – Memory battery testing and replacement
08:11 – Partial assembly for testing and testing
