== Is the A3000 a recap candidate? == The A3000 board uses '''leaded aluminium electrolytics and tantalums''', not the leaking surface-mount electrolytics of the later [[Acorn Archimedes A5000]], A4 laptop and Risc PC. The board therefore ages gently; the urgent items on an A3000 are the '''CMOS backup battery''' (which leaks and corrodes the bottom-left corner — see [[Acorn Archimedes A3000 Maintenance Guide]]) and the '''PSU module'''. A board recap is still reasonable on a 35-year-old machine that is already open, or to chase ripple-related instability.
