Graphical Environment Manager

GEM (Graphical Environment Manager) was a windowing system created by Digital Research, Inc. (DRI) for use with the CP/M operating system on the Intel 8088 and Motorola 68000 microprocessors. Later versions ran over DOS as well. It was a low-cost alternative to Microsoft Windows that was generally much more functional until Windows 3.0 was released, at which point GEM essentially disappeared.

GEM is known primarily as the graphical user interface (GUI) for the Atari ST series of computers, and somewhat less well known as the operating system for a series of PC-like computers from Amstrad. It was also the core for a small number of DOS programs, the most notable being Ventura Publisher. DRI also produced FlexGem for their FlexOS realtime operating system.
