GEOS Commodore 64

The GEOS (Graphic Environment Operating System) was a third party GUI designed for the Commodore 64 computer by Berkeley Softworks released in 1986. 

The GEOS closely resembled the Macintosh 1.0. In its time the GEOS was the second most popular GUI second to the Macintosh 1.0 based on units shipped. A fun detail about GEOS is the reboot icon which consists of the letter R and a drawing of a boot.
