Background and Evolution of RISC OS Open
RISC OS was originally developed by Acorn Computers in the late 1980s as a proprietary operating system for their ARM-based computers. In 2004, RISC OS Open was founded to release the source code under an open-source license, aiming to preserve and extend the platform beyond its commercial lifespan. Since then, the project has released multiple updates, maintained compatibility with legacy hardware, and fostered a dedicated community of developers and users.
Over the years, RISC OS has seen periodic updates, including support for new hardware and features, often driven by community contributions. Its niche status means it is primarily used in education, embedded systems, and among retro computing enthusiasts. The 20-year milestone reflects a sustained effort despite the platform’s limited mainstream presence.
“Celebrating 20 years of open-source development for RISC OS is a testament to the community’s dedication and the platform’s unique place in computing history.”
— John Marshall, RISC OS Open CEO
