Irix
IRIX ( ) is a discontinued operating system developed by Silicon Graphics (SGI) to run on the company's proprietary MIPS workstations and servers. It is based on UNIX System V with BSD extensions. In IRIX, SGI originated the XFS file system and the industry-standard OpenGL graphics system. History SGI originated the IRIX name in the 1988 release 3.0 of the operating system for the SGI IRIS 4D series of workstations and servers. Previous releases are identified only by the release number prefixed by "4D1-", such as "4D1-2.2". The "4D1-" prefix continued to be used in official documentation to prefix IRIX release numbers. Prior to the IRIS 4D, SGI bundled the GL2 operating system, based on UniSoft UniPlus System V Unix, and using the proprietary MEX (Multiple EXposure) windowing system. IRIX 3.x is based on UNIX System V Release 3 with 4.3BSD enhancements, and incorporates the 4Sight windowing system, based on NeWS and IRIS GL. SGI's own Extent File System (EFS) replaces t ...

IRIX Interactive Desktop
IRIX Interactive Desktop (formerly called Indigo Magic Desktop) is a desktop environment normally used as the default desktop on Silicon Graphics workstations running IRIX. The IRIX Interactive Desktop uses the Motif widget toolkit on top of the X Window System found on most Unix systems. The default window manager on the IRIX Interactive Desktop is 4Dwm. History IRIS Workspace is SGI's first desktop environment in IRIX versions 3.0 through 5.0. This was succeeded by Indigo Magic Desktop, introduced in 1993 with IRIX 5.1 on the Indy multimedia workstation. Along with Sun Microsystem's former OpenWindows environment and the Common Desktop Environment from COSE released the same year, these were some of the first desktop environments to be provided by default on a Unix computer system. The Indigo Magic Desktop was renamed to IRIX Interactive Desktop with the release of IRIX 6.5 in 1998. Beginning in 2000, Eric Masson, a passionate user of SGI systems, began work on a recr ...

Silicon Graphics
Silicon Graphics, Inc. (stylized as SiliconGraphics before 1999, later rebranded SGI, historically known as Silicon Graphics Computer Systems or SGCS) was an American high-performance computing manufacturer, producing computer hardware and software. Founded in Mountain View, California in November 1981 by James H. Clark, Jim Clark, its initial market was 3D graphics computer workstations, but its products, strategies and market positions developed significantly over time. Early systems were based on the RealityEngine, Geometry Engine that Clark and Marc Hannah had developed at Stanford University, and were derived from Clark's broader background in computer graphics. The Geometry Engine was the first very-large-scale integration (VLSI) implementation of a geometry pipeline, specialized hardware that accelerated the "inner-loop" geometric computations needed to display three-dimensional images. For much of its history, the company focused on 3D imaging and was a major supplier of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SGI O2
The O2 was an entry-level Unix workstation introduced in 1996 by Silicon Graphics, Inc. (SGI) to replace their earlier Indy series. Like the Indy, the O2 used a single MIPS microprocessor and was intended to be used mainly for multimedia. Its larger counterpart was the SGI Octane. The O2 was SGI's last attempt at a low-end workstation. Hardware System architecture Originally known as the "Moosehead" project, the O2 architecture featured a proprietary high-bandwidth Unified Memory Architecture (UMA) to connect system components. A PCI bus is bridged onto the UMA with one slot available. It had a designer case and an internal modular construction. Two SCSI drives could be mounted on special caddies (1 in the later R10000/R12000 models due to heat constraints) and an optional video capture / sound cassette mounted on the far left side. CPU The O2 comes in two distinct CPU flavours; the low-end MIPS 180 to 350 MHz R5000- or RM7000-based units and the higher-end 150 t ...

4Dwm
4Dwm is the window manager component of the IRIX Interactive Desktop normally used on Silicon Graphics workstations running IRIX. 4Dwm is derived from the older Motif Window Manager and uses the Motif widget toolkit on top of the X Window System found on most Unix systems. 4Dwm on IRIX was one of the first default graphical user interface desktops to be standard on a Unix computer system. 4Dwm refers to " Fourth dimension window manager" and has no relation to dwm. Other X window managers that mimic the 4Dwm look and feel exist, such as 4Dwm theme for IceWM and 5Dwmhttp://5dwm.org/roadmap.html#5Dwm_The_Window_Manager 5Dwm, The Window Manager] which is a Clone (computing), clone/compatible implementation of 4Dwm based OpenMotif. 5Dwm support both the classic SGI look and a modern/polished look and feel with anti-aliased fonts and UTF-8 support.

SGI IRIS 4D
The SGI IRIS series of terminals and workstations from Silicon Graphics was produced in the 1980s and 1990s. IRIS is an acronym for Integrated Raster Imaging System. Overview 68000 The early systems up to IRIS 3000 use the Motorola 68000 series of processors originally, and later models feature early-generation MIPS processors. These systems run the GL2 operating system, a predecessor of the IRIX operating system, which is based on UniSoft UniPlus System V Unix. GL2 uses a proprietary windowing system named mex (Multiple EXposure). The first model, the IRIS 1000, was shipped around November 1983 with an 8 MHz Motorola 68000 CPU. It is a graphics terminal intended to be attached to a VAX-11 system running either VAX/VMS or BSD Unix. The related IRIS 1200 terminal has a 20-slot backplane in its cabinet versus the 10-slot backplane of the IRIS 1000. The IRIS 1400 Workstation (also known as the IRIS Workstation) was shipped only in 1984. It has a 10 MHz Motorola 68010. MIPS ...

MEX (windowing System)
MEX (Multiple EXposure) was a windowing system created by Silicon Graphics, used on 68k-based IRIS systems and early IRIS 4D systems. Rocky Rhodes, Paul Haeberli, Kipp Hickman, "Mex — A Window Manager for the IRIS", '' USENIX Conference Proceedings'', Summer 1985, pages 381–392. MEX was originally loaded over a network through the utilization of GL1 routines kept on a remote host machine, usually a VAX. When the IRIS 1400 workstation and GL2-W (IRIX) were introduced, MEX was allowed to run locally. MEX was used in IRIX from the GL2-W2.1.0 release to the 4D1-2.3 release. With the introduction of 4D1-3.0 (IRIX 3.0), and the complete migration to MIPS processors, support for the GL / GL2 powered MEX ended in the late 1980s, replaced by Sun Microsystems' NeWS and the 4Sight window manager A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Executable And Linkable Format
In computing, the Executable and Linkable FormatTool Interface Standard (TIS) Portable Formats SpecificationVersion 1.1'' (October 1993) (ELF, formerly named Extensible Linking Format), is a common standard file format for executable files, object code, shared libraries, and core dumps. First published in the specification for the application binary interface (ABI) of the Unix operating system version named System V Release 4 (SVR4), and later in the Tool Interface Standard,Tool Interface Standard (TIS) Executable and Linking Format (ELF) SpecificationVersion 1.2'' (May 1995) it was quickly accepted among different vendors of Unix systems. In 1999, it was chosen as the standard binary file format for Unix and Unix-like systems on x86 processors by the 86open project. By design, the ELF format is flexible, extensible, and cross-platform. For instance, it supports different endiannesses and address sizes so it does not exclude any particular central processing unit (CPU) o ...

IRIS GL
IRIS GL (Integrated Raster Imaging System Graphics Library) is a proprietary graphics API created by Silicon Graphics (SGI) in the early 1980s for producing 2D and 3D computer graphics on their IRIX-based IRIS graphical workstations. Later SGI removed their proprietary code, reworked various system calls, and released IRIS GL as the industry standard OpenGL.

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UniSoft
UniSoft Corporation is an American software developer established in 1981, originally focused on the development of Unix ports for various computer architectures. Based in Millbrae, California, it now builds standardization and conformance testing applications for the digital television market. History UniSoft was founded on October 5, 1981, in Emeryville, California. Their original business was Unix development, and they were soon recognized as one of the early implementers of Unix for the emerging 16-bit microcomputer market. By 1989, they had completed over 225 Unix implementations on various hardware platforms, which was estimated to have been about 65% of all such ports. UniSoft's port of Version 7 Unix was the first operating system for Sun Microsystems' Sun-1 workstations and servers. It also developed Apple Inc.'s Unix variant, A/UX, for the Apple Macintosh II. UniSoft UniPlus System V served as the basis of Silicon Graphics' GL2 operating system, which eventually e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System V Unix
Unix System V (pronounced: "System Five") is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as ''Unix System Unification'', which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV. , the AT&T-derived Unix market is divided between four System V variants: IBM's AIX, Hewlett Packard Enterprise's HP-UX and Oracle's Solaris, plus the free-software illumos forked from OpenSolaris. Overview Introduction System V was the successor to 1982's UNIX System III. While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementati ...
