It wasn't much of a leap, after the Apple II and Commodore 64 versions of ComputerEyes had been developed and were on the market, to come up with a version for the 8-bit Atari computers, since it too used the same 6502 processor chip. These computers had developed a large following and sold a reported two million units during their life spans. (Unfortunately, not all of them got ComputerEyes.) They were sold not only in computer shops but also in department stores.
Like the Apple II version of ComputerEyes, the Atari version connected to the computer via the joystick port. Actually, since there weren't enough signals on a single joystick port to send commands to and receive data from the ComputerEyes module, two ports were used!
Graphics and gaming were the Atari's long suits, with several graphics modes available to display images with, so the image quality surpassed that of the Apple and Commodore versions, even though the ComputerEyes hardware was essentially the same.
