The Display Keyboard (DSKY), designed by the Raytheon Corporation, was the method by which Apollo astronauts communicated with the computers on board the Apollo Command and Lunar Modules.
This specimen is of an early version of the design, which was modified for later flights that actually took astronauts to the Moon.
Transferred by NASA to the Museum in 1972.
This object is on display in Human Spaceflight at the Steven F. Udvar-Hazy Center in Chantilly, VA.
