History of Computers: Geoworks is a preemptive multitasking operating system with a user interface similar to those of Microsoft Windows or the Macintosh. Like the earlier versions of Windows it is a DOS extension. Unlike Windows, it also runs on older machines (like PC/XT) with little RAM (640K required).

After its introduction, it promised to be a real alternative to MS-Windows, but due to the fact that no Windows applications could be run under Geoworks and the lack of commercial programs, it could never assert itself against Microsoft Windows.

Included in the Geoworks ensemble package is a word processor, a drawing program, limited desktop publishing capabilities, Tetris and Solitaire games, communications software, and a variety of extras for file management and customization of the interface. Support for a large number of printers and mice is also included, and Geoworks provides automatic access to all DOS and Netware drives.
