I have 3 European retro computers that I'm trying to run on North American power through a step-up transformer. So, I am using 220V/60Hz instead of the European standard of 220V/50Hz.
- BBC Master works 100%
- Commodore C128D works 100%
- Atari 1040ST fails to boot
Obviously, my question mainly concerns the Atari. I am getting 5V and 12V from the PSU, but no video or any other indications of "life". This Atari was reported to be working by the prior owner (in Europe). Does anyone know definitively whether a European ST can/should work on 60Hz power? Any additional advice/warnings about the other machines using 60Hz is also welcome.
