Negotiations to make PC/GEOS an integral part of PC DOS 7.0 failed. IBM released the PC/GEOS-based EduQuest SchoolView network management tool for K-12 schools in 1994. During that time, the popular single 3.5' disk that AOL was distributing on could be hacked to boot the GeoWorks graphical operating environment. The NEC Bundle retailed for around $500.00 with a 1x external CD-ROM, SCSI Interface Controller, Labtec CD-150 amplified stereo speakers and 10 software titles.Ī scaled-down version of GeoWorks was used by America Online for their DOS-based AOL client software from the time of introduction on IBM compatible PCs until the late 1990s when America Online dropped development for graphical DOS in favor of Microsoft Windows. In December 1992 NEC and Sony bundled an OEM version of GeoWorks called the CD Manager with their respective CD-ROM players that sold as retail box add-on peripherals for consumers. Former CEO of GeoWorks claims that GEOS faded away 'because Microsoft threatened to withdraw supply of MS-DOS to hardware manufacturers who bundled Geoworks with their machines'. It was also bundled with numerous PCs at the time, but like other GUI environments for the PC platform, such as GEM, it ultimately proved less successful in the marketplace than Windows.

Each had a name prefixed by 'Geo': GeoWrite, GeoDraw GeoManager GeoPlanner GeoDex, and GeoComm. GEOS was packaged with a suite of productivity applications. GeoWorks saw a market opportunity to provide a graphical user interface for the 16 million older model PCs that were unable to run Microsoft Windows 2.x. Commonly referred to as GeoWorks Ensemble, it was incompatible with the earlier 8-bit versions of GEOS for Commodore and Apple II computers, but provided numerous enhancements, including scalable fonts and multitasking on XT- and AT-class PC clones. In 1990, GeoWorks released PC/GEOS for IBM PC compatible systems. PC/GEOS should not be confused with the 8-bit GEOS product from the same company, which runs on the Commodore 64 and Apple II.

In 2015, Frank Fischer, the CEO of Breadbox died and the operating system was put to a halt until later in 2017 when it was bought out by blueway.Softworks.

Version 4.0 was developed in 2001 by Breadbox Computer Company, LLC, and was renamed Breadbox Ensemble. PC/GEOS was first created by Berkeley Softworks, who later became GeoWorks Corporation.
