In the basement today we have quite a rare machine (for North America:) The BBC Master 128. It's an evolution of the original Acorn BBC Micro from 1981. My first task is to service the PSU and convert it to 120v, then see if this machine is working.

Part 1: This part!
Part 2:    • Refurbishing the BBC Master 128  
Part 3:    • BBC Master mods and improvememts
