Just for the naysayers... The story behind my question was completely innocent. Although I grew up in the 70s I never knew about these. Wasn't a big video game kid (although I did own intellevision). My wife and I were out yard saleing a couple years ago and we saw a sign for a yard sale that lead us back to an old barn. The older gentlemen was having a "barn sale". We walked in, but it was mostly tools and tractor equipment etc. we almost left, but decided to look around a little since we were already there. In the back was a plastic bag in what seemed to be a pile of junk. I opened the back and recognized the atari cartridges in there (the pic I posted from June 29 was everything I found in the bag.), but didn't know what everything else was. As a matter of fact I thought the cassettes were audio stories like I used to have on record when I was a kid - like spiderman, pacman, etc. The old man told me I could have the bag for $5. I had just sold two restaurants and was planning on opening a "retro cafe" in which several "retro" items would be displayed on the walls. So I bought the bag with the intention of displaying the cartridges. The cafe never got opened (yet) and so the bag just sat in my bedroom until a few months ago a friend was over and I showed it to him. He didn't have any idea what the cassettes were either. When we began to do some research on them, I found that I might have struck a "diamond in the rough". I took them to a game shop in charlotte nc who verified and explained to me what they were. I'm not a gamer so I didn't have any use or interest in them so I found a fair value and sold the lot for about 70% of fair value just so I could put a little cash in my pocket and get rid of them quickly. If this is something you are into, then you probably would have loved this lot (pictured from June 29). Geez, when I asked the question a couple months ago, I was just asking because I was really neive about all this. But the person that bought them is very happy and I was happy to have some cash and a really cool story about a good find.
