Acorn 32-bit

The Acorn 32-bit series, developed by Acorn Computers Ltd., marked a new generation of personal computers built on the Advanced RISC Machines (ARM) architecture and powered by the RISC Operating System. Introduced in 1987 with the Acorn Archimedes as the successor to the BBC Micro, these systems offered greater speed and a more streamlined design. The line expanded over the following decade with notable models including the A5000 in 1991, the A4 Laptop in 1992, the Set Top Box in 1994, the A7000 in 1995, and the Phoebe 2100 in 1998.
