RISC OS is an operating system originally developed by English company Acorn Computers. It powered its Archimedes, RISC PC, and A7000 computer lines. Although Acorn no longer exists, RISC OS is still under active development as an open source project, and can be run on various ARM-based minicomputers such as the Raspberry Pi line.
