GEOS (8-bit operating system) fully reverse-engineered and rewritten as C for the cc65 compiler suite. The reverse-engineered source code has been made available at Github. Dozens of official and third-party applications and other products were produced for GEOS. Among the most important and popular were the following: GEOS (8-bit operating system) GEOS ("Graphic Environment Operating System") is a discontinued operating system from Berkeley Softworks (later GeoWorks).
