The Acorn Archimedes A3000 was replaced by the Acorn A3010 and A3020, two simililar but slightly different models, aimed at the home and educational markets.
The A3020 was a lower-cost replacement for A3000 aimed at British classrooms. The case was slightly shorter at the back and an awkward to reach mouse port that was underneath the A3000 was moved to the back.
