What is GEM?

A graphical environment for the IBM PC and the Atari ST. PC GEM was a fairly widely used GUI until the release of Windows 3.0.

Lineo now own GEM, and have released source for GEM/3 and ViewMAX/3 under the GPL - see the Links section.

Links

• GEM open-source developer site
• The Atari archives can occasionally come up with information relevant to PC GEM. In particular, I recommend Professional GEM, a series of articles on GEM development. They're aimed at Atari GEM, but PC GEM is similar enough that nearly all the information comes across.
• David Given's PC GEM archive contains an installer which may help you to crowbar GEM onto your system.
• Trident still supply GEM drivers for some of their video cards. Unfortunately they like to frobnicate their web site every week (or so it seems) and it's not worth my time to keep the link to them updated. So do a Google search for UC51-DOS.EXE and UL61-1.EXE.
• Viglen's FTP site contains an 8514/A driver for GEM. Winsite contains a GEM driver for Carrera cards.
• ATI supply a GEM driver for their EGA Wonder card.
• Artline pages contain all versions of Artline for GEM.
• Downloadable binaries of GEM applications (no source).
• GEM Development and Promotion Pages
• Heinz Rath's pages contain a VESA 800x600 driver, the ViewMAX/3 desktop, and the start of a web browser for GEM.
