These disks are the nearly-forgotten Geoworks Ensemble 1.0.  The 1.x releases
are significant in that they run on ANY PC as long as you have a graphics card,
a 10MB hard drive, a mouse, and 512K RAM.

The "installed" .rar archive is what is written to the hard drive after setup
has completed, but before it has been run for the first time.  This may help
people who want to run it on systems without floppy drives.

Geoworks Pro was more full-featured, but the only distribution method that I
have ever run across for Pro was on 720K 3.5" disks, so this 1.0 version
remains the only version you can install onto a 5.25" floppy system.
