FreeGEM released in 1999 is a windowing system based on Digital Research's GEM which was first released in 1985.[1] GEM stands for "Graphics Environment Manager". FreeGEM is the free software/open source version of GEM developed after Digital Research released the GEM code under the terms of the GNU General Public License free software license.

FreeGEM code works on almost every version of DOS, and runs on almost every IBM compatible PC. One can download all the FreeGEM binaries and source code in one package through the OpenGEM SDK. The OpenGEM SDK also contains language bindings, documentation, and compilers. There are additional FreeGEM resources available through John Elliott's GEM website (see external links below).

OpenGEM is a popular FreeGEM distribution. Other distributions include Owen's FreeGEM Distribution.
