Input wasis given through two Atari keypad controllers, which came with special overlays to show how to type the different commands and letters.<ref>[https://atariage.com/controller_page.html?ControllerID=4&SystemID=2600 Controllers - Atari Keypad], Atari KeypadSystem: Atari 2600, Model Number: CX50, ''Sold in pairs, functionally identical to the Kid's Controller and the Video Touch Pad.
