SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems from 1982 until the mid-1990s. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based on BSD, while versions 5.0 and later are based on UNIX System V Release 4 and are marketed under the brand name '' Solaris''. History SunOS 1 only supported the Sun-2 series systems, including Sun-1 systems upgraded with Sun-2 ( 68010) CPU boards. SunOS 2 supported Sun-2 and Sun-3 ( 68020) series systems. SunOS 4 supported Sun-2 (until release 4.0.3), Sun-3 (until 4.1.1), Sun386i (4.0, 4.0.1 and 4.0.2 only) and Sun-4 ( SPARC) architectures. Although SunOS 4 was intended to be the first release to fully support Sun's new SPARC processor, there was also a SunOS 3.2 release with preliminary support for Sun-4 systems. SunOS 4.1.2 introduced support for Sun's first sun4m-architecture multiprocessor machines (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oracle Solaris
Oracle Solaris is a proprietary Unix operating system offered by Oracle for SPARC and x86-64 based workstations and servers. Originally developed by Sun Microsystems as Solaris, it superseded the company's earlier SunOS in 1993 and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris was registered as compliant with the Single UNIX Specification until April 29, 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. Sun aimed to build a developer and user community with OpenSolaris; after the Oracle acquisition in 2010, the OpenSolaris distribution was discontinued and later Oracle discontinued providing public updates to the source code of the Solaris kernel, ...

Sun386i
The Sun386i (codenamed ''Roadrunner'') is a discontinued hybrid UNIX workstation/ PC compatible computer system produced by Sun Microsystems, launched in 1988. It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems. Hardware Unlike the Sun-3 models, the Sun386i has a PC-like motherboard and "mini-tower"-style chassis. Two variants were produced, the Sun386i/150 and the Sun386i/250 with a 20 or 25 MHz CPU respectively. The motherboard includes the CPU, 80387 FPU, 82380 timer/DMA/interrupt controller and a custom Ethernet IC called ''BABE'' ("Bus Adapter Between Ethernet"). Floppy disk, SCSI, RS-232 and Centronics parallel interfaces are also provided, as are four ISA slots (one 8-bit, three 16-bit) and four proprietary 32-bit "local" bus slots. The latter are used for RAM and frame buffer cards. Two types of RAM card are available, a 4 or 8 MB card, and the "XP Cache" card, incorporating up to 8 MB with ...

OpenWindows
OpenWindows is a discontinued desktop environment for Sun Microsystems workstations which combined a display server supporting the X Window System protocol, the XView and OLIT toolkits, the OPEN LOOK Window Manager (olwm), and the DeskSet productivity tools; earlier versions of OpenWindows also supported the NeWS protocol. It implements the OPEN LOOK GUI specification. OpenWindows was included in later releases of the SunOS 4 and Solaris (operating system), Solaris operating systems, until its removal in Solaris 9 in favor of Common Desktop Environment (CDE) and GNOME 2.0. History OpenWindows 1.0 was released in 1989 as a separately licensed addition to SunOS 4.0, replacing the older SunView (originally "SunTools") windowing system. Its core is the "xnews server", a hybrid window server that as its name implies supports both X11 and NeWS-based applications. The server can also display legacy SunView applications, although this functionality was not well-supported. (A standalo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SVR4
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 implementation. A s ...

Berkeley Software Distribution
The Berkeley Software Distribution (BSD), also known as Berkeley Unix or BSD Unix, is a discontinued Unix operating system developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley, beginning in 1978. It began as an improved derivative of AT&T's original Unix that was developed at Bell Labs, based on the source code but over time diverging into its own code. BSD would become a pioneer in the advancement of Unix and computing. BSD's development was begun initially by Bill Joy, who added virtual memory capability to Unix running on a VAX-11 computer. In the 1980s, BSD was widely adopted by workstation vendors in the form of proprietary Unix distributions such as DEC Ultrix and Sun Microsystems SunOS due to its permissive licensing and familiarity to many technology company founders and engineers. It also became the most popular Unix at universities, where it was used for the study of operating systems. BSD was sponsored ...

Sun Microsystems
Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer components, software, and information technology services. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, Reduced instruction set computer, RISC processors, thin client computing, and virtualization, virtualized computing. At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center. Sun products included computer servers and workstations built on its own Reduced instruction set computer, RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own computer storage, storage systems and a suite of software products, including the Unix-based SunOS and later Solaris operating system, Solaris operating s ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user 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). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Sun4c
Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, first appearing in July 1987, with the launch of the Sun 4/260. The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models. Sun 4/280 was a base system used for building an early RAID prototype. Models Models are listed in approximately chronological order. : In 1989, Sun dropped the "Sun-4" name for marketing purposes in favor of the SPARCstation and SPARCserver brands for new models, although early SPARCstation/server models were also assigned Sun-4-series model numbers. For example, the SPARCstation 1 was also known as the Sun 4/60. This practice was phased out with the introduction of the SPARCserver 600MP series in 1991. The term ''Sun-4'' continued to be used in an engineering context to identify the basic hardware architectur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SunView
SunView (Sun Visual/Integrated Environment for Workstations) is a discontinued user interface toolkit and windowing system from Sun Microsystems, launched in 1985, and included as part of its Unix implementation, starting with SunOS Release 3.0. Sun had introduced support in 1983 for a window-based environment known as the Sun Window System, providing the Sunwindows (or SunWindows) window manager and Suntools (or SunTools) user interface toolkit. SunWindows was one of the first widely used Unix window systems and, unlike later Unix windowing systems, relied on dedicated support in the system kernel, albeit limited to window hierarchy management and therefore being less invasive than other early window system implementations. In SunWindows, graphics device operations were performed by applications and not in the kernel. SunView was introduced as an object-oriented toolkit layer on top of the SunWindows platform to address the increasing complexity of the underlying system and t ...
