This is a guidance computer designed and built for Project Gemini, a two-man spacecraft. It flew on the Gemini 8 mission, on March 16, 1966, piloted by astronauts Neil Armstrong and Dave Scott.

Gemini Guidance Computers were stored-program, digital, real-time, solid state computers, which provided on-board calculations for pre-launch and re-entry, as well as back-up guidance for the launch vehicle during ascent. They were built for NASA by the Federal Systems Division of IBM, located in Owego, New York.

Transferred from NASA to the Museum in 1968.
