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.
