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.
     
        See also {Macintosh file system}, {Macintosh user interface}.
