For questions relating to Acorn's Archimedes computers

The Archimedes line of computers, originated by Acorn Computers, were the first commercially available computers to use the ARM microprocessor. After an interim operating system (Arthur) they used the RISC OS operating system, later used by the RISC PC line.

Use this tag for questions relating to hardware, software, or peripherals of the Archimedes computers, such as the A305, A410/1, A5000, etc.

Questions relating to the A7000 may be better suited to the risc-pc tag.
