Paradox OS for a 68K machine (eg Sage II)
What kind of OS is this?
RISC OS 2 for the Acorn Archimedes machines
RISC OS 3 for the Acorn Archimedes and R260 machines
Arthur (predecessor of RISC OS) for the Archimedes A310
Is there any relation between Arthur and RISCOS? If not, what kind of Os
was Arthur?
