Saturn V LVDC Memory Module

Saturn V Launch Vehicle Digital Computer (LVDC) Memory Module, measuring 6 x 5.75 x 5.25, produced by IBM under NASA contract number NAS 8-11561. The module is a self-contained assembly with memory timing, drive, inhibit and sensing circuits arranged around the core array for use in the LVDC. It has a capacity of 4,096 word locations (28 bits each) of primary storage, and up to eight of these modules could be grouped together for an overall capacity of 32KB. The modules could be operated in either a simplex or duplex mode, as determined by the Memory Control Elements; in simplex, the system utilized its full memory capacity, while duplex mode only used half of the available space but in duplicate to provide redundancy in case of failure. In fine condition.
