Amiga A501 Battery Replacement - Unnecessary Surgery
17I'm not sure if the old girl is going to thank me or curse me for bringing her into the 21st century, but I did just that by replacing the long gone built in battery for my Amiga's A501 memory board's clock with a standard coin cell battery. This is how I did it. Props to a Jan Beta video, which helped put things together for me.
