This is around 150 Commodore 64 disks of various games, I tried them about a year ago and some of them were working I did not try many of them. I cannot vouch for how well they work, but the ones I did try did work. (Heart of Africa, Hardball, Leaderboard Golf). It includes the two disk holders. Also if you need a disk drive let me know I have one available rarely used in box I am looking to get rid of.
