Or just change the PAL on the Apple Memory card.

The larger socket is for a CharGen chip that has duel Char Sets. Eurpoean
or models specifically meant for French Canada have the chip. It's a2764
instead of a 2732.

This is becauseof the "ZipChip" in there.

: I have noticed this also.  The IIc Tech Ref (p.87) says "On all Apple IIc
