FreeGEM

FreeGEM released in 1999 is a windowing system based on Digital Research's GEM which was first released in 1985. GEM stands for "Graphics Environment Manager". Overview FreeGEM is the free software/open source version of GEM developed after Caldera Thin Clients released the GEM code under the terms of the GNU GPL-2.0-only free software license in April 1999. Caldera Thin Clients owned the source code to GEM through Caldera's purchase of the remaining Digital Research assets from Novell on 23 July 1996, who had acquired Digital Research in June 1991. 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 C. Elliott's GEM website. OpenGEM is a popular FreeGEM distribution. Other distributions include Owen's FreeGEM Distribution.
