GEOS

(jee -os) The first all-scientific satellite in geostationary orbit, built by the European Space Agency for the purpose of studying the Earth's magnetosphere. GEOS–1, launched in April 1977, failed to reach its planned orbit; GEOS–2 was successfully launched in July 1978 and operated for two years with the reactivated GEOS–1 and some other satellites. Having become redundant it was boosted into a higher orbit in 1984.

GEOS

A small windowing, microkernel (less than 64 kbytes long) operating system written in heavily bummed assembly language for MS-DOS computers. It multitasks rather nicely on a 6 Mhz Intel 80286 with at least 512K memory.

It was adapted to PDAs by adding pen recognition, which doesn't work very well.

(2) (Graphic Environment Operating System) An earlier graphical user interface (GUI) and application platform from Breadbox Computer Company. Originally developed by Geoworks Corporation, GEOS was first available for the 8-bit Commodore 64 and Apple II in the mid-1980s.

In 1990, PC/GEOS was introduced for DOS-based PCs, and GEOS ran under various DOS versions in notebook computers and handhelds, including Brother's GeoBook and Nokia's Communicator. GEOS was also the first front end to AOL's website, and GEOS SC was a 32-bit version used by Mitsubishi for cellphones in Japan.

DOS-Based GEOS Suites
Breadbox Ensemble (formerly Geoworks Ensemble) included GEOS-based productivity apps and utilities. A School Suite included educational apps, and an Android tablet pre-loaded with GEOS School Suite was proposed.

GEOS was first licensed to Breadbox, Geoworks' largest application developer and training organization. Breadbox acquired the rights to GEOS software in 2003. See Commodore 64, Apple II and DOS.

GeoWorks (formerly Berkeley Softworks) began shipment of GeoWorks Ensemble (Figure 1), its first product for the IBM pC and compatibles market, on November 9, 1990.
GeoWorks Ensemble consists of PC/GEOS (PC/Graphical Environment Operating System), a new state-of-the-art multitasking graphical environment and seven integrated productivity applications designed to run across the full family of IBM-compatible PCs.
The result of three years of research and development is PC/GEOS, the foundation for GeoWorks Ensemble.
System requirements for GeoWorks Ensemble are an 8088 processor or better, 512 kilobytes of RAM, a hard disk, a mouse, and graphics screen capability (Hercules, CGA, EGA, VGA, MCGA).
In addition to PC/GEOS, GeoWorks Ensemble contains an application suite of full-featured productivity software:
GeoWorks Ensemble also includes a unique, two-level, scalable user interface (Figure 3) that adjusts to the user's level of experience.
Geoworks Ensemble is a graphical environment for IBM PCs and compatibles that is full of surprises.
