Famicom Disk System Late Model RAM Adapter with AC Adapter Maintained Maintenance performed: belt replacement, gear adjustment, head adjustment, head cleaning, disk press felt processing, greasing, etc. I have confirmed operation with several disks I own, but some disks with degraded magnetic properties may not be read. Please understand this. I will confirm operation before shipping. Due to the risk of product substitution, returns are not accepted after purchase. Please consider this an item of considerable age before purchasing. I am also listing this on another flea market site, and may remove the listing without notice.
