3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Macintosh \Mac"in*tosh\, n. Same as {Mackintosh}. From WordNet r 1.6 [wn]: macintosh n 1: a lightweight waterproof, usually rubberized, fabric [syn: {mackintosh}] 2: a waterproof raincoat made of rubberized fabric [syn: {mackintosh}, {mac}, {mack}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: 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}.
