RISC OS

RISC OS is a computer operating system originally designed by Acorn Computers Ltd in Cambridge, England in 1987. RISC OS was specifically designed to run on the ARM chipset, which Acorn had designed concurrently for use in its new line of Archimedes personal computers. It takes its name from the RISC (reduced instruction set computing) architecture supported. Fast, compact and efficient, RISC OS is developed and tested by a loyal community of developers and users. RISC OS is not a version of Linux, nor is it in any way related to Windows, and it has a number of unique features and aspects to its design.
