OS/2 – a proprietary operating system, started in 1985 by IBM and Microsoft with a name of “CP/DOS”. Originally, OS/2 was expected to gradually replace DOS and Windows.

In the summer of 1990, Microsoft announced Windows 3.0 and it became a monster hit. The relationship between IBM and Microsoft was already strained, and further development of OS/2 was left entirely to IBM. Microsoft went on to develop NT, enhance Windows, and produce Windows 95.

Eventually, IBM figured out what was wrong and fixed it. OS/2 2.0 and 2.1 used 386 memory management, ran almost all DOS programs, and ran most Windows applications as well. IBM now supports clone computers, and has largely abandoned its PS/2 Microchannel family for the same PCI, ISA, IDE, SVGA architecture everyone else uses.

In the fall of 1994, IBM released Warp (OS/2 3.0) and made its last big marketing push for OS/2. IBM had a product out ten months before Windows 95 would be released. OS/2 was technically a better system than Windows 95 would be, with real program integrity, priorities, and server-quality I/O. None of this was discussed in any of the IBM ads or announcements. Instead, IBM concentrated on a “one button connection to the Internet” through IBM’s expensive public network. It would be six months before IBM released a version of Warp for corporate and campus use (with LAN support) and IBM never succeeded in capturing market share for Warp among home computer users.

Application programs could not interfere with themselves or with each other. The system could natively use larger amounts of memory. Yet the system maintained the command language and file structure of DOS.

Each OS/2 program runs in its own address space. It is common to talk about the old 16-bit programs and the newer 32-bit programs, but OS/2 does not separate the two or treat them differently. More accurately, OS/2 assumes that each of its applications may have a mixture of 16-bit and 32-bit pieces. OS/2 is itself a hybrid system with mixtures of both types of code.

OS/2 recognizes when a program has been constructed using the old 16-bit tools (producing variable sized segments) or with the new 32-bit tools (providing 4K pages). The different EXE file structure changes the way that the program is loaded into memory. Once they start running, however, all modules get the same services and all are assumed to have both 16 and 32-bit components.

Native OS/2 programs open files, request storage, or load programs by calling standard system routines. These routines are packaged in the same sort of Dynamic Link Libraries (DLLs) that are used in Windows. There are 16-bit and 32-bit libraries with versions of all the standard system services, and a program can choose which to call.

The Workplace Shell (WPS) was introduced in OS/2 2.0. WPS is an object-oriented shell allowing the user to perform traditional computing tasks such as accessing files, printers, launching legacy programs, and advanced object oriented tasks using built-in and third-party application objects that extended the shell in an integrated fashion not available on any other mainstream operating system.

The last version of OS/2 4.52 was released in 2001.

The project was re-branded to ArcaOS and is under development by Arca Noae.

Inferno – an operating system designed for building distributed and networked systems on a wide variety of devices and platforms. Inferno was based on the experience gained with Plan 9 from Bell Labs, and currently being developed by Vita Nuova. Applications for this system are written in the Limbo language. The name of the system and some related programs (including Styx, Limbo) come from the Dante’s Divine Comedy.

Inferno can run as a user application on top of an existing operating system or as a stand alone operating system. Most of the popular operating systems and processor architectures are supported:
– Host Operating Systems
– Windows NT/2000/XP
– Irix
– Linux
– MacOS X
– FreeBSD
– Solaris
– Plan 9

Inferno applications are written in Limbo®, a modern, safe, modular, concurrent programming language with C-like syntax. It is more powerful than C but considerably easier to understand and debug than C++ or Java. It is easy to express the concurrency in the physical world directly in Limbo’s syntax. Any Inferno application will run identically on all Inferno platforms.

High level security is an important part of the Inferno system. By using one standard protocol for all network communication, security can be focused on one point and provided at a system level. Inferno offers full support for authenticated, encrypted connections using a certificate based user identification scheme and variety of algorithms.

Inferno 4 was released in 2005 as free software.

Founded in March 2000, Vita Nuova Holdings Ltd is an operating systems and application development company specializing in technologies for distributed applications on network devices and embedded systems.

Oberon – a single-user, multi-tasking system that runs on bare hardware or on top of a host operating system. Oberon is also the name of a programming language in the Pascal/Modula tradition.

The Oberon project was started at the Swiss Federal Institute of Technology in Zürich (ETHZ) in 1985 by Niklaus Wirth and Jürg Gutknecht. Although the project was originally targeted towards in-house hardware, the language and system have now been ported to many computer platforms. Oberon is also a name of a modern integrated software environment.

In 1991, Jürg Gutknecht and his group continued the development towards the ETH Oberon System. The goal was to exploit the inherent potential and features of Oberon to a much larger degree, upgrade the system by a concept of composable and persistent objects, complement the textual user interface by a graphical companion and provide support for the ubiquitous network. In 1995, the first official Oberon System 3 release was finished. Since then, the system has been constantly improved and extended. In 1997, the Release 2.2 including a large palette of applications was published together with a comprehensive hypertext-based documentation. In March 2000, a new release was ready and the system was renamed “ETH Oberon System”.

The original Oberon system is a single-threaded, single-user, co-operative multi-tasking operating system that runs on bare hardware or on top of a hosted operating system as a single-window application. The ETH Oberon System is an extended version that has intrinsic support for persistent objects and for building graphical user interfaces. It presents itself as a hierarchy of modules, many of which export one or several powerful abstract data types. Application modules simply reuse these data types and do not have to care about their implementation at all.

ETH Oberon System highlights:
– Advanced Textual User Interface
– Integrated object support in the kernel
– Object Autonomy and Persistence
– Extensibility by Software Bus Technology
– Fully Hierarchical Composability
– Generalized MVC Scheme
– Powerful GUI Framework Gadgets
– Self-Contained Documents
– Extensibility on Different Levels

The ETH Oberon System package includes several interesting tools and applications. Many of them were developed as productivity tools by ETH assistants and students.

The Oberon system is available free of charge and no registration is required for downloading the material. The source code is available under a BSD-like License.

PureDarwin – a community project to make Darwin more usable (some people think of it as the informal successor to OpenDarwin).
Darwin is the Open Source operating system from Apple that forms the basis for macOS.

The goal of the PureDarwin project is to make Darwin more usable for open source enthusiasts and developers by providing documentation and by enabling them to retrieve, understand, modify, build, and distribute Darwin.

UseD components are specifically released by Apple for use with Darwin, as well as other Open Source components (collectively called “upstream code”). Specifically, it means that we do not use any components from Mac OS X. It also means that we try to stay as close as possible to the “outside world” as in Mac OS X (e.g., regarding the choice of compilers, options, etc.). It does not mean, however, that we do not modify and add to the upstream code, to the extent that the respective licenses allow.

OpenDarwin – a freely available, multi-platform Berkeley Software Distribution (BSD) / Mach 3.0 kernel-based UNIX-like operating system.

The goal of the OpenDarwin project, founded in April 2002, is to create an independent branch of the Darwin operating system that increases collaboration between Apple developers and the open source community. Apple benefits from the project because development in OpenDarwin is often incorporated into Darwin releases; and the open source community benefits since it is given complete control over its own operating system.

The OpenDarwin developers use a version control system called Concurrent Versions System (CVS to manage changes to the OpenDarwin source code. Many of the OpenDarwin developers are Apple employees, whereas others are not. It should be noted that the OpenDarwin project is fully independant of Apple, and has complete control over it’s own code, though they generally try to stay compatible with Apple’s own software.

Like most modern operating systems, OpenDarwin employs a built-in kernel debugger to help the developers find kernel bugs.

The goal of the OpenDarwin project is to provide resources for open source developers to interact and produce products for Apple’s Mac OS X. One of the key aspects of the project is to enable interested Mac OS X developers to be able to retrieve, modify, build, and distribute operating system changes.

The project has a Core Team , similar to the other various BSD projects. We are currently seeking contributors for all aspects of the project, and additions to the Core Team will be chosen from the most active contributors. One of the initial Core Team’s first action items is to establish the rules for how future Core Team and project members will be selected.

OpenDarwin core team members:
– Rob Braun – Founder of darwinfo.org (a now defunct darwin information site), maintainer of xinetd , and contributing author to the UNIX System Administration Handbook.
– Kevin Van Vechten – The Darwin team at Apple.
– Torrey T. Lyons – A committer on the XFree86 Project, Torrey is the founder of the XonX Project. He is a scientist at Mission Research Corporation, Los Angeles.

GNU-Darwin – a project that ports packages of free software to Darwin.

Darwin is an open-source Unix operating system first released by Apple Inc. in 2000. It is composed of code developed by Apple, as well as code derived from NeXTSTEP, BSD, Mach, and other free software projects.

The GNU-Darwin project mission is two-fold: focus on new projects that leverage the unique capabilities of Darwin/Mach, and help Apple users to enjoy the benefits of free software.

The GNU-Darwin Distribution is an amalgamation of the Darwin and GNU operating systems and a large collection of free software compatible with Darwin and Mac OS X. We are commited to Darwin as a free OS, Mac OS X compatibility, and helping users attain the benefits of software freedom.

Founded in November 2000 by proclus, The ports system and package management system were adapted from FreeBSD in order to bring Unix software to Darwin / MacOSX on PowerPC and also on the Intel and AMD x86 architecture.

In 2002, GNU-Darwin extended its services to full-featured mail accounts (with POP, IMAP and webmail support), Web Hosting and file sharing with an original web interface that provides users an easy way to manage their site and, since 2003, shell accounts on a Darwin x86 ssh server.

GNU-Darwin has always been very strident regarding software freedom and dedicated to concrete progress in this direction while concurrently defending digital liberties in general.

The most convenient way to install the distribution is to use the GNU-Darwin Office cd for ppc and x86.
These are NOT bootable cds, they install the distribution (over 250 applications and libraries) on an existing Darwin system.
Requires either Darwin 7 or 8, or MacOS 10.3 or 10.4.
