The Display Keyboard (DSKY) was the method by which Apollo astronauts communicated with the computers on board the Apollo Command and Lunar Modules. A Command module had two DSKYs: one on the main control panel and one in the lower navigation bay. The LM had one, identical DSKY. The interface consisted of a simple numerical keyboard, a row of status lights, and a set of lighted numerical indicators. Astronauts instructed the computer by keying in numerical codes in a "verb - noun" sequence; e.g. "display velocity."
This DSKY was one of two installed on the Command Module of Apollo 16, crewed by John Young, T.K. Mattingly, and C.M. Duke in April 1972.
