The Acorn Archimedes, launched in 1987, is one of the most quietly important computers ever built. It was the first machine to ship with an ARM processor — Acorn’s own design, created because nothing on the market was good enough — and that processor family went on to power most of the phones and tablets in the world.
What it is
The Archimedes is a 32-bit desktop computer built around the ARM2 (and later ARM3 and ARM250) running RISC OS, a fast, tightly written graphical operating system with a distinctive icon bar. For a machine of the late 1980s it was startlingly quick, and it stayed competitive on responsiveness well into the 1990s.
In the UK it was mostly known as an education machine — it followed the BBC Micro into schools — but it also had a strong niche in music, DTP, and technical work.
Why it still matters
- it is the origin point of the ARM architecture
- RISC OS still feels lean and immediate today
- the games library, while small, includes genuine standouts — Star Fighter 3000, Zarch, Elite, Lander
- surviving machines are increasingly collectible as the ARM story gets retold
Owning one today
The Archimedes family spans a lot of models, from the original A300/A400 series through the compact A3000 to the A4000 and A5000. The main hazard with any of them is the same: onboard batteries that leak and destroy the mainboard if left unaddressed. Check and remove the battery before powering on an untested machine.
For a period-correct display, the Acorn-badged Microvitec AKF50 is a natural pairing.
