Sun Solaris (1989) 38 Unix

Solaris is a Unix based operating system created by Sun Microsystems (now purchased by Oracle in 2010). It is the successor to SunOS and was released initially in June of 1992. The OS is based off of System V Unix and its first release was known internally as SunOS 5. This OS was typically used on SPARC based processors, up until 1994 when it began to support x86 and x86-64 based machines. Versions of Solaris up until version 8 are considered abandoned, with version 9's support ending in October 2014.

SunOS (1985) 19 Unix

SunOS was a UNIX based OS derived from BSD. Initially released in 1982, it was the standard OS on Sun Machines at that time. Platforms supported by this OS were the Motorola 68000, the Sun 386i, and the SPARC. SunOS machines are still actually in use today powering dams and bread factories.

SunPC Coprocessor Software (1994) 0 Unix

This is the software required to operate a SunPC co-processor card under Solaris. The SunPC provides Sparc users with IBM PC compatibility and the ability to use MS-DOS, Windows 3.1, or Windows 95 within Solaris.

SuperDOS (1991) 1 Other

BlueBird SuperDOS is a proprietary multi-tasking multi-user system built to run business applications simultaneously over dumb terminals, replacing expensive mainframe/minicomputers with a single commodity PC. Business Computers systems, and then IBM PC systems. It grew to support protected mode on 386/486 systems. Although it uses MS/PC-DOS to install, "Protected Mode SuperDOS is a freestanding operating system that is not dependent on either DOS or the ROM BIOS.". Most applications for it are written in BlueBird SuperDOS Business Basic. and moving-and-storage companies that needed workstations at many points for data entry, but did not want to put a powerful and expensive computer on every desk. Office, Manufacturing, Auto Rental, Van and Storage, Wholesale Distribution, and Word Processing. Most of these were ported from Data General compatible Business Basic software. multi user basic-oriented product was Thoroughbred/OS, and much later Citrix Multiuser attempted to fill a similar role.

Originally released in 1983 by Science Management Corporation and later under Concept Omega Corporation, Thoroughbred/OS is a unique BASIC oriented multi-tasking multi-user operating system for the IBM XT and compatible systems. serial terminals. It can power up to 16 terminals with the right serial expansion cards. All of the applications are written in BASIC, and the shell itself is an interactive BASIC interpreter.

Tru64 UNIX (1999) 3 Unix

Tru64, formerly Digital UNIX, formerly OSF/1 was DEC's UNIX product for their line of Alpha based systems. After DEC's acquisition by Compaq, it was renamed to Tru64. DEC previously had sold a BSD derivative named Ultrix for Vax and MIPS based systems. Their new UNIX on Alpha was meant to counter AT&T and Sun's SVR4 Unix. Tru64 / DIGITAL UNIX / OSF/1 is somewhat interesting in that it used portions of the Mach microkernel and BSD kernel and userland in a manner not entirely unlike NeXTSTEP or Mac OS X. Like OS X, Tru64 itself is not a microkernel system but uses Mach code in its kernel to implement threading and scheduling and possibly other features.

UCSD p-System (1984) 2 Other

The UCSD p-System is a highly portable operating system. It uses the Pascal programming language, and all applications are compiled to interpreted bytecode. This means an application written for the p-System should run on any p-System platform, regardless of the CPU and architecture. However, depending on the use, it could be quite slow. p-System, but it lost its portability advantage as the industry standardized on the x86 IBM PC architecture.
