RISC OS
RISC OS specifications
RISC OS is an operating system designed to run on ARM computers. Originally designed in 1987 by Acorn Computers of England, it was made for use in its new line of ARM-based Archimedes personal computers and was then shipped with other computers produced by the company. Despite the demise of Acorn, RISC OS continues to be developed today by the RISC OS Open community on version 5.0 of the system that was open sourced in 2018.
