The "Block I" Apollo Guidance Computer represented the initial design by the MIT Instrumentation Laboratory, to meet NASA's requirements for on-board Guidance, Navigation, and Control for a Lunar Mission. It was replaced by a more advanced design, called "Block II," as the Apollo program matured. Block I computers were flown on three unmanned Apollo tests between August 1966 and April 1968.
This computer is an unflown unit. It was built by the Raytheon Corporation, and used about 4,000 circuits.
Transferred from NASA to the Museum in 1972.
