All parts have been disassembled and cleaned. Functionality has been verified using multiple software programs and "Burn-in the Cassette" software. Long-term operation has also been confirmed by running Momotaro Dentetsu in a computer-controlled automatic battle mode. The capacitors marked with red circles have been replaced with new ones. Exterior dirt has been cleaned with a melamine sponge. This is the main unit only; the cassette in the photo is not included. It will be shipped within 48 hours.
