 This article gives the specifications for the Apple IIe Card for the
 Macintosh LC and Performa 400, 405, 430, and 450 computers.  For a
 description of the Apple IIe Card software, search under "Apple IIe Card"
 and "software".


 DISCUSSION ------------------------------------------------------

 OVERVIEW
 --------
 The Apple IIe Card lets the Apple Macintosh LC computer and Performa 400
 series run the more than 10,000 Apple IIe programs.  To assure compatibility
 with virtually all Apple IIe applications, the Apple IIe Card contains a
 65C02 microprocessor -- the same one that's built in to the Apple IIe
 personal computer.  The card comes with 128K RAM standard and can use up to
 1MB of Macintosh LC RAM.  A floppy-drive controller and connector ports for
 a 5.25-inch floppy disk drive and an Apple Joystick II are also included.

 The Apple IIe Card takes full advantage of the Macintosh LC Performa 400
 series' components, including the monitor, keyboard, mouse, and internal
 disk drives.  With the superior resolution offered by Macintosh monitors,
 text and graphics generated by Apple IIe applications appear crisp and clear
 in all Apple IIe video modes.  Regardless of the video mode, Apple IIe
 applications run at normal Apple IIe speeds -- or, using an optional mode of
 the Apple IIe Card, they can be run up to twice as fast.
