I have 5 Atari 810 Disk drives that I'm looking to sell. Two of them have Happy enhancements in them. The two drives with the Happy enhancements work but sometimes will not read or write disks. Two of the other drives turn on, disk spins, etc, but will not read disks either. The 5th drive is not complete, but has some parts missing.
If anyone is interested in purchasing them, please let me know. I live in Monroe, NC and could either ship them or meet to give them to you. I really don't know what they are worth in the condition that they are in, but the Happy enhancements both worked the last time the drives read disks.
