Addamax was an American software company that developed Trusted operating systems based on UNIX System V and Berkeley Software Distribution (BSD) variants of UNIX. [1] The company was founded in 1986 in Champaign, Illinois by Peter A. Alsberg and had a sales and development office in Gaithersburg, Maryland.[ citation needed ]
Addamax filed a high-profile antitrust lawsuit in 1991 against the Open Software Foundation (OSF), alleging that OSF created a cartel that controlled the UNIX operating system and exerted monopsony price fixing and led to the company going out of business. [2] [3]
The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif widget toolkit. It was part of the UNIX 98 Workstation Product Standard, and was for a long time the Unix desktop associated with commercial Unix workstations. It helped to influence early implementations of successor projects such as KDE and GNOME, which largely replaced CDE following the turn of the century.
Tru64 UNIX is a discontinued 64-bit UNIX operating system for the Alpha instruction set architecture (ISA), currently owned by Hewlett-Packard (HP). Previously, Tru64 UNIX was a product of Compaq, and before that, Digital Equipment Corporation (DEC), where it was known as Digital UNIX.
The Open Group is a global consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications." It has 900+ member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development. It was established in 1996 when X/Open merged with the Open Software Foundation.
The Open Software Foundation (OSF) was a not-for-profit industry consortium for creating an open standard for an implementation of the operating system Unix. It was formed in 1988 and merged with X/Open in 1996, to become The Open Group.
Ultrix is the brand name of Digital Equipment Corporation's (DEC) discontinued native Unix operating systems for the PDP-11, VAX, MicroVAX and DECstations.
In computing, Motif refers to both a graphical user interface (GUI) specification and the widget toolkit for building applications that follow that specification under the X Window System on Unix and Unix-like operating systems. The Motif look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements.
OSF/1 is a variant of the Unix operating system developed by the Open Software Foundation during the late 1980s and early 1990s. OSF/1 is one of the first operating systems to have used the Mach kernel developed at Carnegie Mellon University, and is probably best known as the native Unix operating system for DEC Alpha architecture systems.
Presentation Manager (PM) is the graphical user interface (GUI) that IBM and Microsoft introduced in version 1.1 of their operating system OS/2 in late 1988.
OPEN LOOK is a graphical user interface (GUI) specification for UNIX workstations. It was originally defined in the late 1980s by Sun Microsystems and AT&T Corporation.
The Unix wars were struggles between vendors to set a standard for the Unix operating system in the late 1980s and early 1990s.
IXI Limited was a British software company that developed and marketed windowing products for Unix, supporting all the popular Unix platforms of the time. Founded in 1987, it was based in Cambridge. The product it was most known for was X.desktop, a desktop environment graphical user interface built on the X Window System. IXI was acquired by the Santa Cruz Operation (SCO) in February 1993.
MkLinux is an open-source software computer operating system begun by the Open Software Foundation Research Institute and Apple Computer in February 1996, to port Linux to the PowerPC platform, and Macintosh computers. The name refers to the Linux kernel being adapted to run as a server hosted on the Mach microkernel, version 3.0.
Trusted Operating System (TOS) generally refers to an operating system that provides sufficient support for multilevel security and evidence of correctness to meet a particular set of government requirements.
The following tables compare general and technical information between a number of notable IRC client programs which have been discussed in independent, reliable prior published sources.
The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but also had many problems. Bell Labs, frustrated by the size and complexity of Multics but not its aims, slowly pulled out of the project. Their last researchers to leave Multics – among them Ken Thompson, Dennis Ritchie, Doug McIlroy, and Joe Ossanna – decided to redo the work, but on a much smaller scale.
The Common Open Software Environment (COSE) was an initiative formed in March 1993 by the major Unix vendors of the time to create open, unified operating system (OS) standards.
Unix International (UI) was an association created in 1988 to promote open standards, especially the Unix operating system. Its most notable members were AT&T and Sun Microsystems, and in fact the commonly accepted reason for its existence was as a counterbalance to the Open Software Foundation (OSF), itself created in response to AT&T's and Sun's Unix partnership of that time. UI and OSF thus represented the two sides of the Unix wars in the late 1980s and early 1990s.
The Berkeley Software Distribution or Berkeley Standard Distribution (BSD) is a discontinued operating system based on Research Unix, developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley. The term "BSD" commonly refers to its open-source descendants, including FreeBSD, OpenBSD, NetBSD, and DragonFly BSD.
Locus Computing Corporation was formed in 1982 by Gerald J. Popek, Charles S. Kline and Gregory I. Thiel to commercialize the technologies developed for the LOCUS distributed operating system at UCLA. Locus was notable for commercializing single-system image software and producing the Merge package which allowed the use of DOS and Windows 3.1 software on Unix systems.
The History of the Berkeley Software Distribution begins in the 1970s.
