== Capacitor health == The A3000 main board uses leaded aluminium electrolytics and tantalums plus surface-mount ceramic decouplers; the PSU module has its own electrolytics and mains-side suppression capacitors. None of the board electrolytics are the leaking surface-mount type found on the later [[Acorn Archimedes A5000]] and Risc PC, so the board itself ages gently — the battery and the PSU are the priorities. Full designator list and procedure: [[Acorn Archimedes A3000 Capacitor Guide]].
