An Apollo-era Coincident Current Core Memory Plane, 6 x 6.25, which represents a fascinating example of early random access memory (RAM), similar to the type that was used in the Apollo Guidance Computer (AGC). A close-up view of the memory plane reveals the wires threading the doughnut-shaped ceramic magnetic cores. Arrangement of the wiring through the cores allows the computer to address any one of the cores in the memory plane (representing a single bit as 0 or 1). Mounted with thumb tacks and framed to an overall size of 8.75 x 8.5; one of the thumb tacks is loose inside the frame.
