Frog Pond

Frog Pond is a games that Atari never officially released to the public. 2 different versions exist with this - one with a "rainbow" title screen, and one with a detailed graphics screen (most likely the final version). An even earlier (work-in-progress) version was shown at the Summer 1982 CES show. Prototypes (and possibly copies) have been available for some time now. Best Electronics had it for $12 at one time.
