Wrong, it depends on which Mac you have.  To be sure, see what it says
on the voltage panel on the back.

Short list of US Macs that *can* work on 120-240 V:

	Mac II
	Mac IIx
	Mac IIfx
	SE
	SE/30
	IIsi
	IIcx
	IIci

Short list of US Macs that *cannot* work on 240 V:

	Original 128K
	512K
	512KE
	Mac Plus
	Portable (when plugged in :) with US charger/power supply)
	Classic (though might be a jumper inside you can change)
	LC (I think--again, might be a jumper for 240 if so)
	Laserwriter
	Imagewriter

Finally, don't trust *me*, look at the UL label on the back.
