 By plugging this card into a Macintosh LC (and later models incorporating an LC PDS slot), through hardware and (some) software emulation, the Macintosh can run most software written for the 8-bit Apple IIe computer.This miniaturized computer on a card was made possible by a chip called the Mega II, first used in the Apple IIGS computer to emulate the Apple IIe.The Mega II duplicates all the functions of a standard Apple IIe, minus RAM, ROM and CPU.
