Digital Research's GEM (Intel 8086 version!)
GEM was a very close match for the MacOS - the same on-screen layout of menu bar at the top of the screen, then windows below - the first version of the GEM Desktop had a wastepaper basket. Then Apple took DRI to court and got the bin and some other stuff taken out, with the end result that GEM became much less like the Mac.
GEM was one of the first commercially available GUIs 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 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. Like the Macintosh interface and Microsoft Windows, GEM provides a windowed environment for running programs.
IBM PC class machines code.
The first retail version was GEM 1.2 (9/85)
The last retail version was GEM 3.13 (4/89)
After Apple's lawsuit and DRI's continued weak marketing of GEM, the original developers began to leave (literally run) in other directions.
Lee Lorenzen and Dan Meyer, started ventura software continued to customize the GEM sys, never affected by DRI's 'apple' problems.

Also includes the GEM Resource Editor (RCS)
The 2.3 version was enhanced to support the setting of 'state bit' flags in GEM resources. The setting of such bits can be used to override the way the AES displays border styles.
The Resource Construction Set (RCS.APP) includes a new icon editor that provides many convenient ways to create your icon or image. It can also scale your icon for different resolutions. Both high and low resolution resources are now provided.
The utility LMAP2SYM is also included. It is used to convert a large model map file generated by LINK to a sym file needed by GEMSID for symbolic debugging. For those who use PLINK, PMAP2SYM is the corresponding utility.
