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 IBM PC XT- and AT-class PC clones. In 1990, GeoWorks (formerly Berkeley Softworks) released PC/GEOS for IBM PC compatible systems. 2.1 Zoomer devices Tandy Z-PDA, AST GRiDPad 2390, Casio Z-7000 & XL 7000.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 efforts on the operating system stopped until later in 2017 when it was bought by blueway.Softworks. Version 4.0 was developed in 2001 by Breadbox Computer Company, limited liability company (LLC), and was renamed Breadbox Ensemble. PC/GEOS was first created by Berkeley Softworks, which later became GeoWorks Corporation. Versions for some handheld platforms were also released and licensed to some companies. Originally released as PC/GEOS, it runs on DOS-based, IBM PC compatible computers. GEOS (later renamed GeoWorks Ensemble, NewDeal Office, and Breadbox Ensemble) is a computer operating environment, graphical user interface (GUI), and suite of application software.
