Extremely rare Ground Support Equipment RCA-110A Launch Computer Core Memory Module, 8″ x 10.25″ x 5″, bearing an affixed Radio Corporation of America parts tag reading, “Product Spec. NA 2273, Assy. No. 1608889-501, Ser. No. 16C,” with another below, “Logistic Serial No. 0009, Date Cleaned 6/13/69.” One side of the module has six serial-type ports labeled “J7” through “J12,” and an additional label provides instructions for appropriate connector mating. In fine condition. Originating from the RCA-110A computer, which served as the ‘brains’ for Saturn system checkout during its time on the launch pad, this core memory is believed to have been de-integrated from one of the RC-110A computers that supported most if not all Apollo launches.
