The Acorn Archimedes was the first general-purpose home computer based on the 32-bit ARM RISC CPU from Acorn Computers Ltd. The term 'Archimedes' is also commonly used to describe Acorn computers that were not officially called Archimedes, but were based on the same architecture.
It was first released in the UK in 1987, and used an operating system called ARTHUR, allegedly standing for "A Risc-based operating system by THURsday" (later versions were named RISC OS). The current version of RISC OS is version 4, and it runs on the RISC PC.
Please only submit sites relevant to the emulation of the Acorn Archimedes range to this category.
For sites about the actual Acorn Archimedes please consider submitting to: Computers: Systems: Acorn: Archimedes.
For emulation of other platforms on the Archimedes, please submit to the relevant Computers: Emulators category. For example a Sinclair ZX Spectrum emulator that runs on RISC OS should be submitted to Computers: Emulators: Sinclair: ZX Spectrum not Computers: Emulators: Acorn: Archimedes.
