Apollo Guidance Computer

c. 1965 MIT/Raytheon, United States
Developed by Eldon Hall at the MIT Instrumentation Laboratory and manufactured by Raytheon, this is an engineering prototype of the computer that guided the Apollo Lunar Excursion Module (LEM) from lunar orbit through its descent to the moon’s surface. It could also perform the computations for a computer-piloted landing, but the astronauts usually took over manual control for this critical procedure.
The Display and Keyboard Unit (DSKY), was designed for ease of in-flight operation and was controlled by the astronauts with a verb/noun syntax commands such as “display" + “velocity.”

Developed by the MIT Instrumentation Laboratory under the direction of Eldon Hall and manufactured by Raytheon, this is an engineering prototype of the computer that guided the Apollo Spacecraft Command Module (CM) from Earth orbit to the Moon and the CM’s return to Earth surface. It guided the Lunar Module (LM) from lunar orbit through its descent to the moon’s surface and return to rendezvous with the CM in lunar orbit. During the critical landing procedure it accepted manual steering commands from the astronauts to make a safe landing.
