What is RISC OS?
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 RISC OS Developments Ltd. You can find out more at sites such as riscos.info, The Icon Bar and RISCOSitory. Also take a look at the printed RISC OS magazine, Archive, first published in the same year as the Arm launch.
