This appears to be the last version that was worked on before the game
was scrapped. Although there is some interaction with the screens

There is a hidden message in the rom code that says:
GATO, The Atari 7800 Version by Jack Sandberg, Sr. Software Engineer,
ibid inc., West Hartford, CT., Ver. 1.0 04/24/87 -- Security String
