Protos (aka Lab Loaners):
Atari CRAZY Prototype Lab Game Crazy Climber
I don’t think that everybody knows what these “lab loaners” and protos are exactly. Quick and symplified description: these were done to test the games, to show them before releasing (mass production) and for previews-reviews in magazines. That’s why you must consider them one-of-a-kind: these are handmade.
