GEOS (Graphic Environment Operating System) is a discontinued operating system from Berkeley Softworks (later GeoWorks). Originally designed for the Commodore 64 with its version being released in 1986, enhanced versions of GEOS later became available in 1987 for the Commodore 128 and in 1988 for the Apple II family of computers. A lesser-known version was also released for the Commodore Plus/4.
GEOS closely resembles early versions of the classic Mac OS and includes a graphical word processor (geoWrite) and paint program (geoPaint).
A December 1987 survey by the Commodore-dedicated magazine Compute!'s Gazette found that nearly half of respondents used GEOS.[1](p4) For many years, Commodore bundled GEOS with its redesigned and cost-reduced C64, the C64C. Second chance updated mac os. At its peak, GEOS was the third-most-popular microcomputer operating system in the world in terms of units shipped, trailing only MS-DOS and Mac OS (besides the original Commodore 64's KERNAL).[citation needed] Quaddro 2 mac os.
Other GEOS-compatible software packages were available from Berkeley Softworks or from third parties, including a reasonably sophisticated desktop publishing application called geoPublish and a spreadsheet called geoCalc. While geoPublish is not as sophisticated as Aldus Pagemaker and geoCalc not as sophisticated as Microsoft Excel, the packages provide reasonable functionality, and Berkeley Softworks founder Brian Dougherty claimed the company ran its business using its own software on Commodore 8-bit computers for several years.
Development[edit]
Written by a group of programmers, the GEOS Design Team:[2] Jim DeFrisco, Dave Durran, Michael Farr, Doug Fults, Chris Hawley, Clayton Jung, and Tony Requist, led by Dougherty, who cut their teeth on limited-resource video game machines such as the Atari 2600, GEOS was revered[citation needed] for what it could accomplish on machines with 64–128 kB of RAM memory and 1–2 MHz of 8-bit processing power.
Unlike many pieces of proprietary software for the C64 and C128, GEOS takes full advantage of many of the add-ons and improvements available for these systems. Commodore's 1351mouse is supported by GEOS, as are its various RAM expansion units. GEOS 128 also fully supports the C128's 640×200 high-resolution VDC display mode through a compatible RGB monitor.
The C64 version of GEOS incorporates a built-in fast loader, called diskTurbo, that significantly increases the speed of drive access on the slow 1541. GEOS is the first Commodore software that could use a floppy disk as swap space or virtual memory.[3] GEOS 128 can take advantage of the C128's enhanced 'burst mode' in conjunction with the 1571 and 1581 drives. The Commodore version of GEOS uses a copy protection scheme that renders users' disks unbootable if it detects that the disk has been illegally duplicated.[4]

Via Berkeley's special geoCable interface converter or other third-party interfaces to connect standard RS-232 or Centronics printers to the Commodore serial bus, GEOS supports a wide variety of printers, including HPPCL printers and the Apple LaserWriter. Baldis basics rp mac os. This ability to print to high-end printers was a major factor in making GEOS a desktop publishing platform.
The Apple II version of GEOS was released as freeware in August 2003. The Commodore 64/128 versions followed in February 2004.
The latest GEOS desktop suite for IBM PC compatibles is Breadbox Ensemble. Revivals were seen in the OmniGo handhelds, Brother GeoBook line of laptop-appliances, and the NewDeal Office package for PCs. Related code found its way to earlier 'Zoomer' PDAs, creating an unclear lineage to Palm, Inc.'s later work. Nokia used GEOS as a base operating system for their Nokia Communicator series, before switching to EPOC (Symbian).

Reverse engineering efforts[edit]
On August 19, 2016, Michael Steil posted in his blog[6] that the source code for GEOS 2.0 for Commodore C64 had been fully reverse-engineered the cc65 compiler suite. The reverse-engineered source code has been made available at Github.[7]
