Apollo Command Module Sequential Events Control System Lunar Docking Events Controller (LDEC), measuring approximately 6 x 12 x 8.5, with four connectors on top labeled “J1” through “J4,” and a fifth on the front labeled “J5.” No parts tags or numbers are present. Scattered soiling and adhesive remnants, otherwise fine condition. The LDEC, in parallel with the LM Separation Sequence Controller (LSSC), was responsible for energizing pyro squibs to separate the Lunar Module from the Spacecraft LM Adapter; it subsequently sequenced final separation of the LM docking ring during Lunar Module jettison from the Command Module.
