Twenty Years of RISC OS Open

RISC OS Open Ltd marked its 20th anniversary on June 20, 2026, reflecting on its mission to open-source a proprietary operating system that began in 2006. Over two decades, the organization has released the OS across multiple platforms—from BeagleBoard to Raspberry Pi—while establishing community-driven development processes like nightly autobuilds and a bounty scheme that allow users to contribute code and fund desired features. The initiative has successfully revitalized RISC OS, bringing the vintage operating system to new hardware and introducing it to new generations of users.
