- The 50 hz timing should really have no effect on the computer itself. The
- power supply supplies "pure" full bridge DC at 5 and 12 volts to all computer
- components. In addition, most power supplies have a switch on them to allow
- them to work directly from either 110V or 220V power lines.
-
- As for the monitor, a lot of newer monitors can actually adapt to 110/220
- 50/60 hz and other worldwide standards automatically. Check your monitor
- docs before you try this, unless you like living dangerously [heh heh].
-
- As for dot matrix printers, their power supplies are usually similar to
- computer switching power supplies and generally supply only DC current to
- the printer, so most will work fine on 50/hz.
-
- Take a close look at the power supply rating stickers first.
