Macintosh
     
         (Mac) A range of single user, 32-bit {personal
        computers} manufactured by {Apple Computer, Inc.}, originally
        based on the {Motorola 68000} {microprocessor} family and a
        proprietary {operating system}.  The Mac was Apple's successor
        to the {Lisa}.
     
        The project was proposed by {Jef Raskin} some time before
        {Steve Jobs}'s famous visit to {Xerox PARC}.  Jobs tried to
        scuttle the Macintosh project and only joined it later because
        he wasn't trusted to manage the {Lisa} project.
     
        The {Macintosh user interface} was notable for popularising
        the {graphical user interface}, with its easy to learn and
        easy to use {desktop} metaphor.
     
        The {Macintosh Operating System} is now officially called
        Mac OS.
     
        The first Macintosh, introduced in January 1984, had a
        {Motorola 68000} {CPU}, 128K of {RAM}, a small {monochrome}
        screen, and one built-in {floppy disk} drive with an external
        slot for one more, two {serial ports} and a four-voice sound
        generator.  This was all housed in one small plastic case,
        including the screen.  When more memory was available later in
        the year, a 512K Macintosh was nicknamed the "Fat Mac."
     
        The standard Macintosh screen {resolution} is 72 {dpi} (making
        one {point} = one {pixel}), exactly half the 144 dpi
        resolution of the ancient {Apple Imagewriter} {dot matrix}
        printer.
     
        The Mac Plus (January 1986) added expandability by providing
        an external {SCSI} port for connecting {hard disks}, {magnetic
        tape}, and other high-speed devices.
     
        The Mac SE (March 1987) had up to four megabytes of {RAM}, an
        optional built-in 20 megabyte hard disk and one internal
        expansion slot for connecting a third-party device.
     
        The Mac II (March 1987) used the faster {Motorola 68020} {CPU}
        with a 32-bit {bus}.
     
        In 1994 {PowerPC} based Macs, {PowerMacs}, were launched, and
        in 1999, the {iMac}, updated on 2002-01-07.  PowerMacs clocked
        at over 1GHz were planned for 2002-01-22, to be followed by
        dual 1GHz processors and "Superdrive" (combined DVD-ROM,
        DVD-RW, CD-ROM, CD-RW).
     
        If "Macintosh" were an acronym, some say it would stand for
        "Many Applications Crash, If Not, The Operating System Hangs".
        While this was true for pre Mac OS 9 systems, it is less true
        for Mac OS 9, and totally incorrect for Mac OS X, which has
        protected memory, so even if one application crashes, the
        system and other applications are unaffected.
