What is GEOS?
GEOS used to be an acronym for Graphical Environment Operating System, back when Berkeley Softworks made Commodore GEOS for the Commodore 64 and 128. Then Berkeley Softworks changed its name to Geoworks and developed PC/GEOS for Intel-compatible personal computers. GEOS was then used on small hand-held devices such as the Tandy Z-PDA and Nokia 9000 Communicator. Then GEOS was being maintained by NewDeal, as part of their NewDeal Office suite.
