Keyboard, Display (DSKY), Apollo Guidance Computer

Although computers controlled much of an Apollo mission automatically, there were several parts of a mission where an astronaut's interaction with the computer was critical. The Display Keyboard (DSKY, pronounced as a word "diskey") was the primiary interface between Apollo astronauts and the computers on both the 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 specimen is probably an unflown version used for tests.

Transferred to the National Air and Space Museum to NASA in 1976.
