GEOS Commodore 64 Commodore 128 a version mouse joystick GUI Amiga Byte multimedia computer operating system PCs personal computer
In the Commodore world, GEOS was available on the Commodore 64 and Commodore 128. Later, a version was available for PCs running DOS. It could be used with a mouse or a joystick as a pointing device, and came with a suite of GUI applications. Commodore's later product line, the Amiga platform, ran a GUI operating system by default. The Amiga laid the blueprint for future development of personal computers with its groundbreaking graphics and sound capabilities. Byte called it "the first multimedia computer... so far ahead of its time that almost nobody could fully articulate what it was all about."
