This cartridge came with the first VCSes Atari sold. Forgive me for enjoying such trivia but this is a 2 KiloByte program, while VCS big carts are 8K and the common small ones are 4KB. By saving just $1 per unit times one million units is like a million dollars directly into somebody's pocket, Atari could've saved even more by repurposing 4KB chips tested to have bad cell(s) in the half intended to go unused. 2K is so small a game, I know no other (on model 2600, "Syntron" is a model 800 game less than 2KB size). Atari did the same trick on Space Invaders 1980 cartridge for model 800, they put a 4KB game on half of an 8KB memory area.
