Apollo Command Module (Block II) Premodulation Processor equipment manufactured by Collins, measuring approximately 5˝ x 10˝ x 7˝, with a tag on the end reading: "Premodulation Processor Equipment, NAA S&ID PN ME478-0068-006…Contract No. NAS 9-150, Date of Mfr. 29 Jan 69…Mfd. by Collins Radio Co. for the Apollo Spacecraft, Serial No. 026728100021." The unit is labeled "C28-1A111” on the top, and features connectors “J1” through “J4.” In fine condition.

The processor is of solid state design and modular construction, with redundant circuitry for it mission-critical application. It provided the interface connection between the spacecraft data-gathering equipment and the S-band RF electronic—thus, it was essentially the brains of the Apollo CM's telecommunications system.
