This device is part of the Attitude Control and Maneuver Electronics (ACME) for the Gemini spacecraft designed by Honeywell, Inc. The ACME provided attitude control, automatically or manually, during all flight phases of a mission. It worked in conjunction with the spacecraft rate gyros, inertial platform, horizon sensors, computer, and hand inputs to provide commands to the craft's thrusters.
This specimen was installed on the Gemini 8 spacecraft, which flew in March 1966.
Transferred by NASA to the Museum in 1970.
