What did I just find here today? (Atari 400/800 prototypes?)

[Armageddon Potato]

Hello! I wanted to ask what this is, as I found some unusual looking Atari 400/800 games at a flea market today. I collect prototype stuff personally, but I am not as familiar with prototype Atari 400/800 stuff. What did I find here?






I don't know what the missing-label games are, but when I get home tomorrow I can check.

Thanks! -Danny

Did you open them up. I believe those are just a hobbyist that copied ROM's and used donor carts. I just ran into a lot just like that. I opened them up and saw they were copies stuff in other shells.
