Apollo CM Block II Electronic Control Assembly (ECA), measuring approximately 23.5″ x 5.75″ x 6″ and weighing 17 lbs, with the top featuring four ports and the back featuring a Honeywell parts label: “Electronic Control Assembly, Mfr. Part No. BG286H2, NAA/S & ID Control No. ME901-0705-0402, Contract No. M7J7XAH-470005A, Mfr. Serial No. 10028AAE1021, Mfr. Date 6 June 1969.” In fine condition, with scattered marks and scratches.
A key component of the Apollo spacecraft's guidance, navigation, and control system, the Electronic Control Assembly (ECA) served as a central ‘brain’ of the Apollo Command Module, responsible for processing data, making decisions, and controlling various critical systems to ensure the success of Apollo missions, including the iconic Apollo 11 mission that successfully landed astronauts on the Moon. Some of its responsibilities included processing critical data for guidance and navigation, controlling the firing of the Reaction Control System, and managing the ignition, shutdown, and performance of the Service Propulsion System.
