ChorusOS – a highly scalable and reliable embedded operating system that has established itself among top telecommunications suppliers. The ChorusOS operating system is used in public switches and PBXs, as well as within access networks, cross-connect switches, voice-mail systems, cellular base stations, web-phones, and cellular telephones.

The Sun Embedded Workshop software provides a development environment with the necessary tools to build and deploy the ChorusOS operating system on a telecommunications platform. The ChorusOS operating system is the embedded foundation for Sun’s Service-Driven Network. Offering high service availability, complete hardware and software integration, management capabilities and JavaTM technology support dedicated to telecom needs, the ChorusOS operating system allows the dynamic and cost-efficient deployment of new features and applications while maintaining the reliability and functionality of existing networks.

The ChorusOS operating system supports third-party protocol stacks, legacy applications, and applications based on real-time and Java technology, on a single hardware platform.

The ChorusOS operating system can be tuned very finely to meet the requirements of a given application or environment. The core executive component is always present in an instance of the ChorusOS operating system. Optional features are implemented as components that can be added to, or removed from, an instance of the ChorusOS operating system.

Each API function in the ChorusOS operating system is contained in one or more of the configurable components. As long as at least one of these components is configured into a given instance of the operating system, the function is available. Some library functions are independent of any specific component and are always available.

ChorusOS 5.0 runs over Solaris operating environments, and supports the following targets:
– UltraSPARC II (CP1500 and CP20x0)
– Intel x86, Pentium
– Motorola PowerPC 750 and 74×0 processor family (mpc7xx)
– Motorola PowerQUICC I (mpc8xx) and PowerQUICC II (mpc8260) microcontrollers

The last version | Released: 1.3.1

HeliOS – an open-source, Unix-like operating system for parallel computers developed by Perihelion Software. Helios was developed by the (now defunct) company called Perihelion Ltd., mainly targeting the INMOS Transputer but later adding other CPUs like the ARM series or TMS320c4x DSPs when INMOS’ decline became clear.

Perihelion Software Limited was a United Kingdom company founded in 1986 by Dr. Tim King along with a number of colleagues who had all worked together at MetaComCo on AmigaOS and written compilers for both the Amiga and the Atari ST.

The HeliOS primary architecture is the Transputer. The transputer is a series of pioneering microprocessors from the 1980s, featuring integrated memory and serial communication links, intended for parallel computing.

The last version | Released: R10.4.1.2 | March 1992

Domain/OS – an Unix-like and Multics*-like the Apollo/DOMAIN operating system produced by Apollo Computer, Inc. (founded in 1980 in Chelmsford, Massachusetts, by William Poduska) from 1980 until 1989, when it was purchased by Hewlett-Packard. It was originally launched in 1981 as AEGIS, and was rebranded to Domain/OS in 1988.

The first Apollo/DOMAIN systems were the DN100s, of which 2 were shipped on March 27, 1981 with Aegis SR1 installed on them to Harvard University (information provided by Jim Ward). Documentation for Aegis SR1 consisted of 3 books written by Penny Orwick. The DN100s were discarded by Harvard University a few years ago (Harvard CS Help Desk).

The latest OS that is available for Apollo’s is Domain/OS SR10.4.1.2 (SAU7) and SR10.4.1.1 (all other SAUs), consisting of 5 tapes for SR10.4 and 3 tapes for the SR10.4.1 upgrade. Hewlett-Packard offers some patches for Apollo/DOMAIN machines (You are now required to register (free) to retrieve any patches) (Domain/OS SR10.3.5 and SR10.4/SR10.4.1). Those patches bring the OS up to SR10.4.1.2. All the SAUs from SAU1 thru SAU6 (all three-digit machines except the new HP/Apollo 4xx Series) were dropped at SR10.4 and thus can’t run Domain/OS SR10.4 operating system. SAU1 (DN100, DN400, DN420, DN600) was dropped at about SR9.7.5 or SR9.7, thus making SAU1 systems (DN100, DN400, DN420, DN600) the only ones that can’t run any of the SR10 systems.

The DN10000 machines run a different OS release, with a .p suffix, which stands for PRISM, the name of the DN10000 CPU’s architecture (Parallel Reduced Instruction Set Machine), e.g. SR10.4.p. The latest OS for DN10000’s is SR10.4.1.2.p, consisting of the 5 basic install tapes for SR10.4.p, one upgrade tape for SR10.4.1.p and HP’s patches.

Apollo was one of the first vendors of graphical workstations in the 1980s, featuring a display manager which was integrated with the operating system’s own window manager known as wmgr.

*Multics (“Multiplexed Information and Computing Service”) is an influential early time-sharing operating system based on the concept of a single-level memory.

Sprite – a research operating system developed at the University of California, Berkeley, by John Ousterhout’s research group.

Sprite is a distributed operating system that provides a single system image to a cluster of workstations. It provides very high file system performance through client and server caching. It has process migration to take advantage of idle machines. It was used as a testbed for research in log-structured file systems, striped file systems, crash recovery, and RAID file systems, among other things.

The Sprite project has now ended, although Sprite is still running on a few machines. If you have a DECstation 5000/200 or a SparcStation 2, you could try running Sprite off the Sprite CD-ROM.

The one single archive contains following files:
– bench.tar.Z: Sources for a collection of small benchmarks used in the paper “Why Aren’t Operating Systems Getting Faster as Fast as Hardware”.
– gdb.tar.Z: gdb for Mach 3.0. (missing)
– gld.tar.Z: Gnu linker with modifications for cross-linking between different machine types.
– hash.tar.Z: The Sprite hashing package. You’ll also need the list package.
– list.tar.Z: The Sprite list package.
– mab.tar.Z: Sources for Modified Andrew Benchmark (used in paper “Why Aren’t Operating Systems Getting Faster as Fast as Hardware” and for other purposes).
– mipsim.tar.Z: A simulator and assembly-language program debugger for the MIPS R2000 architecture, written by John Ousterhout for use in a freshman-level course in C and assembler.
– tcl: A subdirectory full of various files containing sources and documentation for Tcl and Tk and related packages. See the README file in that directory for more information.
– xtsim.tar.Z: library to interface event driven simulator to Xt toolkit.
– sprite-1.096.tar.Z: Sprite kernel sources, version 1.096. Won’t compile into a kernel, but useful for browsing or borrowing code.
– sprited.tar.Z: Sources for a Mach-based Sprite single-server. Mostly of interest only to people doing work with Mach.
– cdrom.txt: Information about Sprite sources and docs on CDROM.

ULTRIX – an operating system made by DEC (Digital Equipment Corporation), based on the 4.2BSD UNIX operating system with improvements 4.3BSD and System V Release 2 Contain various improvements that are specific to the digital hardware systems.

First Ultrix-32 was based on 4.2BSD with some of the features of System V, and released in 1984.
Its purpose was to be a pure UNIX for VAX with support for DEC. Later, Ultrix-32 added support for DECnet DEC and other appropriate protocols such as LAT.

ULTRIX runs on VAX and MIPS (R2000, R3000 or R4000 series).

The file systems support:
– can read/write: UFS (RW)e36, NFS (RW)e36
– can read: ISO 9660 (R)e100
– can read/write through third party or optional software: FAT (RW)w55 [using “mtools”, a set of MS-DOS utilities for UNIX, SMB (through SAMBA)

The latest version Ultrix-11 V4.5 was released in November 1995.

The Digital Equipment Corporation was bought in 1998 by Compaq, and starting from 2002 the Compaq is a part of Hewlett-Packard.
