I want to bring mine over to Europe where 50 Hz is what comes out of the plug. I guess that the real-time clock would be something you often control by the mains. I'm not worried about the video frame rate, since switchable terminals are always run at 60 Hz rate anyway in order to minimze the flicker, and that works fine. I suppose that the voltage will be the problem, since the supply is probably not switchable to 220 V. (At least it wasn't on Apple II) -- Bjorn -------

Apple told us (and it came out in print in the next Consortium newsletter that all that is needed is a good quality voltage converter since 50 Hz is still within the Mac's operating range. They don't use the line frequency for any kind of clock. Alan Crosswell Columbia University Computer Center -------
