RISC iX is a discontinued Unix operating system designed to run on a series of workstations based on the Acorn Archimedes microcomputer.[1] Heavily based on 4.3BSD, it was initially completed in 1988, a year after Arthur but before RISC OS.[2] It was introduced in the ARM2-based R140 workstation in 1989,[3] followed up by the ARM3-based R200-series workstations in 1990.[4]
