Well, I'm kinda stuck. The power switch is shot. I could repair the housing, but the contacter element is missing. At the moment it's just a plastic rod.
I have found a small part rolling around in the housing, but I'm not sure if it's the missing contacter or not. I've added pictures to my Google Drive here: https://drive.google.com/drive/folders/0B-nu1y5KwPr4MDBXcjBZNXQ3T2M I tried shorting the pins on the power switch to check that the machine powers up, but I don't get consistent results each time I do. The machine appears to power on, but I haven't gotten a startup splash on the monitor, just vertical lines. I might be shorting the wrong pins on the switch, given my experience level. If the switch is irreparable, I'll have to get a new one from a scrap unit. I don't suppose anyone has a Tandy 200 power switch that I could buy? Any advice would be appreciated.
