The display-and-keyboard interface Apollo astronauts used with the guidance computer was the DSKY.
DSKY stood for “display and keyboard” and served as the human interface for the Apollo Guidance Computer. It combined numeric displays, indicator lights, and a calculator-style keypad so astronauts could enter commands and read navigation data.
Apollo crews operated it through a structured Verb-Noun system. A Verb specified an action, such as displaying or starting something, while a Noun identified the data involved. This let astronauts interact with a computer that had extremely limited memory by modern standards.
DSKY is often confused with the guidance computer itself. The AGC was the computer; the DSKY was the control and display unit connected to it. Other Apollo abbreviations referred to spacecraft guidance systems, inertial hardware, or launch-vehicle computers, but they were not the astronaut-facing keyboard interface.
