Acorn A4000

Acorn · 1992

The A3020's boards in a separate desktop case with a detachable keyboard, for buyers who wanted an Archimedes that looked like a workstation rather than a home computer. Mechanically the most conventional of the ARM250 machines and the easiest to work in. Uncommon, having sold in far smaller numbers than the wedges either side of it.
