Apollo Command Module (Block II) Pulse Code Modulation (PCM) Telemetry Assembly, measuring 13.75″ x 7.25″ x 14″ and weighing 42.5 pounds, with the front bearing its parts tag from Radiation, Inc. of Melbourne, Florida, which reads: “NAA S&ID PN ME901-0719-0005, Date of Mfr. 16 Sept 66, Collins Radio Co. PN 5140041-010, Mfd. By Radiation, Inc. for the Apollo Spacecraft.” The back also bears a parts label: “Serial No. 071208040006, Part No. 514-0045-010.” The top, which is labeled “C13-1A101,” contains a total of 18 ports, with the left side featuring an additional three ports. The unit received and sampled analog, parallel digital, and serial digital information, which consists of astronaut biomedical, spacecraft operation, and scientific data. It then converted the data to a single serial output for transmission to Earth. This single-output signal was routed to the Premodulation Processor for transmission to the ground or to Data Storage Equipment. In fine condition, with scattered scuffs and marks, and some chipping to the paint. A large, impressive piece of Command Module technology.
