DeviceLogics was a company in Lindon, Utah, USA, founded in November 2002. Originally doing business mostly under the DeviceLogics name, the company was incorporated as DRDOS, Inc. for legal reasons. The DeviceLogics name was later dropped.
Bryan Wayne Sparks co-founded the company, together with Bryce Burns and Troy Tribe, and acquired DR-DOS from the Canopy Group, a Utah technology venture group. Copies of DR-DOS 7.03 have been licensed and distributed by this company. [1] [2] [3] [4] The company's web site went offline in 2018.
In 1994, Bryan W. Sparks, with help from Novell's Raymond John Noorda, founded Caldera, Inc. Caldera bought DR-DOS from Novell in 1996. [5]
DR-DOS is a disk operating system for IBM PC compatibles, originally developed by Gary A. Kildall's Digital Research, Inc. and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. Upon its introduction in 1988, it was the first DOS that attempted to be compatible with IBM PC DOS and MS-DOS.
GEM is a discontinued operating environment released by Digital Research in 1985. GEM is known primarily as the native graphical user interface of the Atari ST series of computers, providing a WIMP desktop. It was also available for IBM PC compatibles and shipped with some models from Amstrad. GEM is used as the core for some commercial MS-DOS programs, the most notable being Ventura Publisher. It was ported to other computers that previously lacked graphical interfaces, but never gained traction. The final retail version of GEM was released in 1988.
Digital Research, Inc. was a privately held American software company created by Gary Kildall to market and develop his CP/M operating system and related 8-bit, 16-bit and 32-bit systems like MP/M, Concurrent DOS, FlexOS, Multiuser DOS, DOS Plus, DR DOS and GEM. It was the first large software company in the microcomputer world. Digital Research was originally based in Pacific Grove, California, later in Monterey, California.
Novell, Inc. was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi-platform network operating system known as Novell NetWare. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide.
FreeGEM released in 1999 is a windowing system based on Digital Research's GEM which was first released in 1985. GEM stands for "Graphics Environment Manager".
Caldera International, Inc., earlier Caldera Systems, was an American software company that existed from 1998 to 2002 and developed and sold Linux- and Unix-based operating system products.
Star Trek is the code name that was given to a secret prototype project, running a port of Macintosh System 7 and its applications on Intel-compatible x86 personal computers. The project, starting in February 1992, was conceived in collaboration between Apple Computer, who provided the majority of engineers, and Novell, who at the time was one of the leaders of cross-platform file-servers. The plan was that Novell would market the resulting OS as a challenge to Microsoft Windows, but the project was discontinued in 1993 and never released, although components were reused in other projects. The project was named after the Star Trek science fiction franchise with the slogan "To boldly go where no Mac has gone before".
CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system's DOS BIOS during boot. CONFIG.SYS was introduced with DOS 2.0.
Raymond John "Ray" Noorda was a U.S. computer businessman. He was CEO of Novell between 1982 and 1994. He also served as chairman of Novell until he was replaced in 1994.
The Canopy Group is an American investment and property management firm founded by Ray Noorda in 1995 through the Noorda Family Trust. It is headquartered in Lindon, Utah. At various times it has consisted of, or been known as, Canopy Technologies, Canopy Properties, and Canopy Ventures.
ViewMAX is a CUA-compliant file manager supplied with DR DOS versions 5.0 and 6.0. It is based on a cut-down runtime version of Digital Research's GEM/3 graphical user interface modified to run only a single statically built application, the ViewMAX desktop. Support for some unneeded functions has been removed whilst some new functions were added at the same time. Nevertheless, the systems remained close enough for ViewMAX to recognize GEM desktop accessories automatically and to allow some native GEM applications to be run inside the ViewMAX environment. Many display drivers for GEM 3.xx could be used by ViewMAX as well, enabling ViewMAX to be used with non-standard display adapters and higher resolutions than possible using the default set of ViewMAX drivers. Also, Digital Research's SID86, the symbolic instruction debugger that shipped with DR DOS 3.xx and provided dedicated functions to debug GEM applications, could be used for ViewMAX as well.
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers.
Lineo was a thin client and embedded systems company spun out of Caldera Thin Clients by 20 July 1999.
Arachne is an Internet suite containing a graphical web browser, email client, and dialer. Originally, Arachne was developed by Michal Polák under his xChaos label, a name he later changed into Arachne Labs. It was written in C and compiled using Borland C++ 3.1. Arachne has since been released under the GPL as Arachne GPL.
The AARD code was a segment of code in a beta release of Microsoft Windows 3.1 that would issue a cryptic error message when run on the DR DOS operating system rather than the Microsoft-affiliated MS-DOS or PC DOS. Microsoft inserted the code in an attempt to manipulate people into not using competing operating systems; it is an example of the company's fear-uncertainty-doubt tactics.
Fear, uncertainty, and doubt (FUD) is a manipulative propaganda tactic used in sales, marketing, public relations, politics, polling, and cults. FUD is generally a strategy to influence perception by disseminating negative and dubious or false information, and is a manifestation of the appeal to fear.
Caldera, Inc. was a Canopy-funded software company founded in October 1994 and incorporated on 25 January 1995 by former Novell employees Bryan Wayne Sparks, Ransom H. Love and others to develop the Caldera Network Desktop (CND) and later create a Linux distribution named OpenLinux (COL). The company was originally based in Provo and later in Orem, Utah, USA.
DOS Protected Mode Services (DPMS) is a set of extended DOS memory management services to allow DPMS-enabled DOS drivers to load and execute in extended memory and protected mode.
In computing, a hardware code page (HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator's resident read-only memory and are thus not user-changeable. They are available for use by the system without having to load any font definitions into the device first. Startup messages issued by a PC's System BIOS or displayed by an operating system before initializing its own code page switching logic and font management and before switching to graphics mode are displayed in a computer's default hardware code page.
DR-WebSpyder is a DOS web browser, mail client and operating system runtime environment that was developed by Caldera UK in 1997. It was based on the DR-DOS operating system and networking components from Novell as well as the Arachne web browser by Michal Polák of xChaos software. The system was designed to run on low-end desktop systems, but being able to boot and execute from disk as well as from ROM or network, it was also tailored for x86-based thin clients and embedded systems with or without disk drives. Using the web browser as its principal user interface, it could be also used for kiosk systems and set-top boxes. It was ported to Linux in 1999 under the name Embrowser and was renamed Embedix Browser in 2000.
