Yes. The NTSC IIe uses a 2332 or 2732 video ROM/EPROM. The PAL IIe
uses a 2364/2764 chip to provide a choice of US-ASCII or the appropriate
character set for the country of sale. Based on the IIgs reference manual,
it appears that Apple support the following:
USA PAL & NTSC
UK PAL
French PAL
Danish PAL
Spanish PAL
Italian PAL
German PAL
Swedish PAL
This left French Canadians with a problem so Apple made an adapter socket
to allow the use of the French character set on an NTSC motherboard.
>Can I fit a US video rom in a PAL Apple IIe?
Yes, although you will loose the UK pound, a-acute, c-cedilla etc characters.
You should also leave the language switch under your keyboard in the
USA position.
Just make sure it is plugged into pins 3-26 (away from the notch at the
pin 1+28 end of the socket).
