Famicom Disk System Late Model RAM Adapter with AC Adapter Maintenance Completed Maintenance includes belt replacement, gear adjustment, head adjustment, head cleaning, disk press felt processing, and greasing. I have confirmed operation with several disks I own, but disks with degraded magnetic properties may not be read. Therefore, I do not guarantee the reading of all disks. I will confirm operation before shipping. Due to the risk of substitution, returns are not accepted after purchase. Please examine the images carefully and purchase with the understanding that this is a vintage item. I am also listing this item on another flea market site, and may remove the listing without notice.
