I've been asked what is required to make MAC's
(Plus, SE, CI, FX)  from
North America run in Africa.
I took a quick looked at a few of mine and didn't notice a switch on the
back of the powe supply like some of the older PC's had.
Is the costs worth the cost of shipping? 
Many early macs were world machines, just use a cable with the
correction plug for that country and the mac worked fine without
diddling any switches or anything. Here is a link to the Apple Spec

Something I tell people about older computers, anything is SO much
better than nothing.
