This is an unflown example of a "Block I" display keyboard (DSKY) developed by Raytheon for the Apollo program. It was the primary means by which astronauts communicated with the Apollo on-board guidance computer. The Block I design was used in several unmanned flights, but it was replaced by a more advanced design for the piloted flights, which took astronauts to the Moon and back, and to several missions in near Earth orbit.
Transferred from NASA to the Museum in 1972.
