ARX – a Mach-like operating system written in Modula-2+[3] developed by Acorn Computers Ltd. ARX is a comprehensive OS going beyond UNIX but backwards compatible is expected to be provided with a layer on top. Lightweight processes, share a common address space, amounts to little more than multiple program pointers with no mutual protection. Obviously this means that switching between such processes (called threads) is extremely fast.

ARX it has written in Modula 2 and is reputed to UNIX like. An interesting point for RISC haters is that the code compiled for the Archimedes is less than twice the size of the same code compiled for the 32016, which is very definately a CISC (Complex Instruction Set .. Computer).

Apparantly Acorn are not releasing details of the ARX operating system because they do not want to “confuse the market”. Even software houses, as a whole, have not been told about ARX. Whilst this may be just because ARX isn’t ready for release yet my paranoid brain worries about it’s price.

It was not finished in time to be used in the Acorn Archimedes range of computers, which shipped in 1987 with an operating system named Arthur, later renamed RISC OS.

Genera – a proprietary, commercial operating system and integrated development environment for Lisp machines created in 1982 by Symbolics. It is a fork of an operating system created on the Massachusetts Institute of Technology (MIT) AI Lab’s Lisp machines which Symbolics had used in common with Lisp Machines, Inc. (LMI), and Texas Instruments (TI).

Symbolics is currently a privately held company which acquired the assets and intellectual property of the old public company called Symbolics, Inc. The old Symbolics was the premier producer of special-purpose computer systems for running and developing state-of-the-art object-oriented programs in Lisp. It designed and built workstations as well as writing a fully object-oriented operating system and development environment called “Genera” to run on those workstations. Symbolics also created a number of software tools to work with Genera. The new Symbolics continues to sell and maintain these products, along with Open Genera which runs on Alpha processor based workstations running Tru64 Unix. If you would like to know why you should be interested in developing your application in Genera, click here to see 25 reasons. Symbolics also distributes the Macsyma and PDEase software products for Windows PCs.

FedBerry – a Fedora Remix specifically built for use with Raspberry Pi® 2/3 Model B computers.

FedBerry allows people to easily install and use Fedora on the RPi2/3. FedBerry was created when Fedora did not previously support the Raspberry Pi 2/3 Model B (RPi2/3).

FedBerry is an optimised Fedora remix which fully supports all RPi2/3 hardware.

The major differences between Fedora arm releases as compared to Fedberry releases are:
• The use of our own custom kernels (using the Raspberry Pi foundation’s bcm2709 kernel port).
• The use of Raspberry Pi foundation’s own bootloader (ie. we don’t use uboot).
• The use of swap files in lieu of swap partitions.
• tmpfs is enabled but size limited to 100M.
• The root partition is automatically expanded on first boot.
• Various RPi specific applications / software are included by default.
• To facilitate optional headless booting, a default root password is set in the ‘minimal’ release.

JavaOS – a closed source, based on a Java virtual machine, and written in Java operating system developed by Sun Microsystems. JavaOS is a highly compact operating system designed to run Java applications directly on microprocessors in anything from net computers to pagers.

JavaOS brings the design advantages of the Java™ programming language to an operating system. As perhaps the smallest and fastest OS that runs Java, JavaOS enables Java on a broad range of devices. JavaOS will run equally well on a network computer, a PDA, a printer, a game machine, cellular telephone, or countless other devices that require a very compact OS and the ability to run Java.

In addition, JavaOS has been built to be fully ROMable for embedded applications, and can run with as little as 512K ROM and 256K RAM. For network computers, an entire system with JavaOS, the HotJava™ Browser and space for downloading Web content and applets requires only 3MB ROM and 4MB RAM. JavaOS can be this small because it is almost completely written in Java.

JavaSoft, headquartered in Cupertino, CA, is an operating company of Sun Microsystems Inc. The company’s mission is to develop, market and support the Java technology and products based on it. Java supports networked applications and enables developers to write applications once that will run on any machine. JavaSoft develops applications, tools and systems platforms to further enhance Java as the programming standard for complex networks such as the Internet and corporate intranets.

SparkyLinux – a desktop-oriented operating system based on the Debian operating system. The project offers a ready to use operating system with a set of various customized lightweight desktops to choose from.

The project was born on October, 2011 as an Ubuntu remix with Enlightenment as the default desktop having the name ue17r (Ubuntu Enlightenment17 Remix). After a few months of testing, the base system was changed to Debian and it was renamed to SparkyLinux.

The default desktop environments are LXQt (former LXDE), MATE and Xfce but users can install other desktops via ‘Sparky APTus’.

As Sparky iso image features a few proprietary packages, the ‘Sparky APTus’ provides a small tool called ‘Non-Free Remover’ which can easily uninstall all ‘contrib’ and ‘non-free’ packages from the system.

Special Editions:
– GameOver Edition, targeted to gamers. It features a large set of free and open-source games and some needed tools;
– Rescue Edition, provides a live system and a large number of applications for recovering broken operating systems;
– Multimedia for audio, video and html pages creating;

SparkyLinux is still under active development, the post is published on 10th Sparky anniversary.

Flint OS – a fast, simple and productive operating system built on open source Chromium OS.

Flint began with a vision where all applications and services we use today will be living in the Cloud. With the ever advancing browser platform technology and web frontend performances, it’s not surprising that most things we do today with the internet can be done through a single browser window. Powered by Cloud technology, driven by the open source community, equipped with an optimized custom kernel, bundled with the best browser platform and incorporating numerous user experience enhancements, Flint OS is here to take you to a new horizon of computing.

Flint OS works perfectly on most x86 and ARM based hardware platforms. We are particularly interested in making Flint OS run on single-board-computer (SBC) solutions based on ARM architecture, such as the Raspberry Pi, SBCs with RK3288 and RK3399 chips.

On March 6, 2018 Neverware announced about acquiring Flint Innovations, creators of Flint OS.
