The Apple IIe Card For Macintosh
In March 1991, shortly after the release of the Macintosh LC series, Apple released the PDS slot-based Apple IIe Card for the Macintosh. 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.
Many of the built-in Macintosh peripherals can be "borrowed" by the card when in Apple II mode (i.e. extra RAM, 31⁄2 floppy, AppleTalk networking, clock, hard disk). It can run at an accelerated 2 MHz. As video is emulated using Macintosh QuickDraw routines, it sometimes can not keep up with the speed of a real Apple IIe in slower machines. With a specialized Y-cable, the card can use an actual Apple 5.25, Apple UniDisk 3.5 or even Apple II joystick/paddles. The Apple IIe Card is thought of as an Apple II compatibility solution or emulator rather than an extension of the Apple II line.

Famous quotes containing the words apple and/or card:
“No people require maxims so much as the American. The reason is obvious: the country is so vast, the people always going somewhere, from Oregon apple valley to boreal New England, that we do not know whether to be temperate orchards or sterile climate.”
—Edward Dahlberg (19001977)
“Mothers are not the nameless, faceless stereotypes who appear once a year on a greeting card with their virtues set to prose, but women who have been dealt a hand for life and play each card one at a time the best way they know how. No mother is all good or all bad, all laughing or all serious, all loving or all angry. Ambivalence rushes through their veins.”
—Erma Bombeck (20th century)
