AFAIK, the LCD is powered from the //c's video expansion port. In it
there's a VCC line that allows a few miliamperes to be drawn from it, to
feed the RF modulator or the LCD screen (both are very low-power
devices). It's also done that way because the LCD screen plus a 12 V
battery pack make the //c actually a portable machine - and it wouldn't
make any sense having to power the screen from a 110/220 V. outlet when
the rest of the computer runs off a battery.

Would anyone on this list in the UK have an Apple IIc UK power supply
available for sale? I finally realised a long standing ambition to
find an Apple IIc with the LCD screen and recently acquired one from
the US. (Another childhood dream achieved, thanks eBay). Also, does
anyone know whether the LCD is driven off the IIc or has its own PSU?
I didn't ask when I bought it as I didn't want to be put off getting
it! How sad is that? Regards, John.
