RISC OS Open Ltd. (also referred to as ROOL) [1] [2] is a limited company engaged in computer software and IT consulting. [3] It is managing the process of publishing the source code to RISC OS. [4] Company founders include staff who formerly worked for Pace, the company which acquired RISC OS after Acorn's demise. [5]
The source code publication was initially facilitated by a shared source initiative (SSI) between ROOL and Castle Technology (CTL), [6] prior to a switch to the more widely recognised Apache licence in October 2018. [7] ROOL hopes that by making the RISC OS source code available for free it will help stimulate development of both the RISC OS source code and the platform as a whole. [8] [9]
ROOL set initial goals to make the source code easily available (on the web), and also to establish a wiki, forum and bug tracker. [10] These have been available since December 2006. [11]
Operations exist to facilitate tasks related to ROOL's goals. Additionally, staff undertake development work on the code themselves. Since early 2009, ownership, development and sales of the Acorn C/C++ tools were transferred to RISC OS Open. [12] As an extension to the initial goals, in 2011 ROOL introduced a bounty scheme to encourage further development. [13]
Attendance at RISC OS computer shows is often arranged, with other knowledgeable coders sometimes standing in when ROOL staff are unavailable. [14] A Facebook page and Twitter feed was created in 2012 to communicate events via social media. [15] [16]
A number of book titles have been published starting in 2015 with the RISC OS Style Guide, a three book set in support of the Desktop Development Environment, BBC BASIC Reference Manual and the RISC OS 5 User Guide.
Online discussions take place on the forum. Developers can seek technical assistance with writing software, debugging, and porting the operating system to new hardware. End users can seek assistance with applications, emulation, and enquiries of a more general nature. A common area exists to make announcements that are broadly related to the theme of RISC OS, and discussion of future wish list features or applications.
Risc PC was a range of personal computers launched in 1994 by Acorn and replaced the preceding Archimedes series. The machines had a unique architecture unrelated to IBM PC clones and were notable for using the Acorn developed ARM CPU which is now widely used in mobile devices.
RISC is an abbreviation for reduced instruction set computer.
RISC OS is a computer operating system originally designed by Acorn Computers Ltd in Cambridge, England. First released in 1987, it was designed to run on the ARM chipset, which Acorn had designed concurrently for use in its new line of Archimedes personal computers. RISC OS takes its name from the reduced instruction set computer (RISC) architecture it supports.
The Iyonix PC was an Acorn-clone personal computer sold by Castle Technology and Iyonix Ltd between 2002 and 2008. According to news site Slashdot, it was the first personal computer to use Intel's XScale processor. It ran RISC OS 5.
The Phoebe 2100 was to be Acorn Computers' successor to the RiscPC, slated for release in late 1998. However, in September 1998, Acorn cancelled the project as part of a restructuring of the company.
These tables provide a comparison of operating systems, of computer devices, as listing general and technical information for a number of widely used and currently available PC or handheld operating systems. The article "Usage share of operating systems" provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers.
NetSurf is an open-source web browser which uses its own layout engine. Its design goal is to be lightweight and portable. NetSurf provides features including tabbed browsing, bookmarks, and page thumbnailing.
Castle Technology Limited, named after Framlingham Castle, was a British computer company based in Cambridge, England. It began as a producer of ARM computers and manufactured the Acorn-branded range of desktop computers that run RISC OS.
The A9home was a niche small-form-factor desktop computer running RISC OS Adjust32. It was officially unveiled at the 2005 Wakefield Show, and is the second commercial ARM-based RISC OS computer to run a 32-bit version of RISC OS. When the Iyonix PC was withdrawn from sale, the A9home remained the only hardware to be manufactured specifically for the RISC OS marketplace.
The Fourth Dimension (4D) was a major video game publisher for the BBC Micro, Acorn Electron, Acorn Archimedes and RiscPC between 1989 and 1998. Previously, The Fourth Dimension had been known as Impact Software, which specialised mainly in BBC Micro games. Some of 4D's staff had worked for Superior Software. Notable release included Cyber Chess, Stunt Racer 2000, Galactic Dan and Chocks Away.
Acorn User magazine was founded by Acorn Computers in 1982, contract-published by Addison-Wesley, to coincide with the launch of the BBC Micro. It covered the range of Acorn home computers, the BBC Micro and Atom at first and later the Electron, Archimedes and Risc PC.
RISCOS Ltd. was a limited company engaged in computer software and IT consulting. It licensed the rights to continue the development of RISC OS 4 and to distribute it for desktop machines from Element 14 and subsequently Pace Micro Technology. Company founders include developers who formerly worked within Acorn's dealership network. It was established as a nonprofit company. On or before 4 March 2013 3QD Developments acquired RISCOS Ltd's flavour of RISC OS. RISCOS Ltd was dissolved on 14 May 2013.
Drobe was a computing news web site with a focus on the RISC OS operating system. Its archived material was retained online, curated by editor Chris Williams until late 2020.
The Icon Bar is a computing and technology website with a focus on the RISC OS computer operating system.
Acorn C/C++ is a set of C/C++ programming tools for use under the RISC OS operating system. The tools use the Norcroft compiler suite and were authored by Codemist and Acorn Computers. The tools provide some facilities offered by a fully integrated development environment.
RISC OS, the computer operating system developed by Acorn Computers for their ARM-based Acorn Archimedes range, was originally released in 1987 as Arthur 0.20, and soon followed by Arthur 0.30, and Arthur 1.20. The next version, Arthur 2, became RISC OS 2 and was completed and made available in April 1989. RISC OS 3 was released with the very earliest version of the A5000 in 1991 and contained a series of new features. By 1996 RISC OS had been shipped on over 500,000 systems.
VirtualAcorn is the brand name of several commercial emulators of Acorn Computers computer hardware platforms.
In computing, Aemulor is an emulator of the earlier 26-bit addressing-mode ARM microprocessors. It runs on ARM processors under 32-bit addressing-mode versions of RISC OS. It was written by Adrian Lees and released in 2003. An enhanced version is available under the name Aemulor Pro.
Impression is a desktop publishing application for RISC OS systems. It was developed by Computer Concepts and initially made available in pre-release form during 1989, having been demonstrated in February 1989 at the Which? Computer Show and subsequently announced as being available from June 1989. The "completed" version was eventually delivered on 18th January 1990.

We really want to stimulate development both in and around RISC OS
The whole project is based on the fundamental premise that the software will die out if there are no developers.
According to Steve Revill at the South East Show, RISC OS Open Ltd. has been formed to achieve a number of goals: Provide an interface for people to get at the source code of RISC OS; Manage developer forums; Manage a faults database; Provide a wiki for people to contribute to
