RISC OS is a computer operating system designed in Cambridge, England by Acorn. First released in 1987, its origins can be traced back to the original team that developed the ARM microprocessor. RISC OS is owned by Castle Technology Ltd.

An amount of developer funding may be available for aspects of this project.

  • RISC OS has been ported to OMAP3 processors and currently runs on the BeagleBoard and related hardware.
  • Looking to the future, RISC OS will be capable of running on OMAP4 processors, available in products such as the PandaBoard. Achieving this is currently conceived as being a twofold process:
    • Single-core implementation; and
    • Multi-core utilisation and preemptive multitasking.
  • Relevant discussions can be followed on the RISC OS Open forum:
