This is a maintenance item for the Pioneer LaserActive CLD-A100 and PAC-S1 (Mega Drive). In preparation for the sale, the following operations and maintenance have been performed: * LD/CD playback possible * PAC-S1 (Mega Drive) recognition possible * Mega CD reading possible * Mega LD reading possible * Mega Drive software reading possible * All capacitors on the PAC connection board have been replaced. (Capacitors tend to lose their capacity over time, which can cause the Mega CD/LD to not be recognized, but this has been addressed by replacing them with new capacitors.) * Pickup lens cleaned * Tray rubber belt replaced * PAC-S1 internal battery replaced + holder added ※ The game software used for operation check is not included. The exterior has no noticeable scratches or stains, but please refer to the photos for details. I will consider a slight price reduction, so if you are interested, please leave a comment.
