TL;DR
RISC OS Open has celebrated its 20th anniversary, marking two decades of open-source development for the RISC OS platform. The milestone underscores its sustained community effort and evolving relevance in computing.
RISC OS Open celebrated its 20th anniversary on March 15, 2024, marking two decades since the platform’s transition to open-source development. The milestone highlights the platform’s sustained community effort and evolving relevance in the computing world, especially among enthusiasts and niche users.
RISC OS Open was established in 2004 to develop and maintain the RISC OS operating system as an open-source project. Over the past 20 years, the project has grown through contributions from a dedicated community of developers, hobbyists, and companies. The anniversary was marked by a series of online events and reflections from key figures involved in the project, including updates on ongoing developments and future plans. RISC OS, originally developed by Acorn Computers in the 1980s, has seen a resurgence in interest due to its lightweight design and unique architecture, appealing to retro computing fans and embedded system developers alike. The project continues to maintain core features, with recent efforts focusing on improving hardware support and modernizing certain aspects of the OS. While the community remains active, challenges include limited mainstream adoption and hardware compatibility issues, which the project aims to address moving forward.Why the 20-Year Milestone Matters for RISC OS and Its Community
The 20th anniversary underscores the resilience and dedication of the RISC OS open-source community, which has maintained and evolved the platform despite limited mainstream adoption.

Historical Background and Recent Developments in RISC OS
Originally developed by Acorn Computers in the 1980s, RISC OS was designed for ARM-based computers, gaining popularity for its efficiency and simplicity. In 2004, the source code was released as open-source under the RISC OS Open project, allowing community-driven development. Over the years, the project has seen periodic updates, with notable milestones including hardware support expansions and interface improvements. The platform has maintained a niche but dedicated user base, often centered around retro computing and embedded applications. Recent years have seen efforts to modernize the OS further, including adapting it for newer hardware and improving compatibility with contemporary peripherals. The anniversary celebration in 2024 reflects both the platform’s longevity and ongoing community engagement, despite challenges such as limited commercial support and hardware limitations that persist today.
“Celebrating 20 years of open-source development for RISC OS is a testament to the dedication of our community and the platform’s enduring relevance.”
— John Cartmell, RISC OS Open CEO
