GEM
     
         One of the first commercially available
        {GUI}s.  Borrowing heavily from the {Macintosh} {WIMP}-style
        interface it was available for both the {IBM} compatible
        market (being packaged with {Amstrad}'s original {PC} series)
        and more successfully for the {Atari} ST range.  The PC
        version was produced by {Digital Research} (more famous for
        {DR-DOS}, their {MS-DOS} clone), and was not developed very
        far.  The Atari version, however, continued to be developed
        until the early 1990s and the later versions supported 24-bit
        colour modes, full colour {icons} and a nice looking sculpted
        3D interface.
