GEM operating system
One of the first commercially available GUIs. 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.
