This artifact, a flight ready spare, was designed at the Marshall Space Flight Center in Huntsville, Alabama for the Saturn V flight control system.
It consists of 10 Texas Instruments gold base metal hermetically sealed transistors, 20 glass Zener diodes, and 20 Allen Bradley carbon composition resistors. The back of the circuit board contains electrical connector pins using gold in their construction. The high strength fiberglass circuit board is coated to protect the components from the environment.
The multipin interface connector has a triangular NASA certification stamp and 50M65845-1 designates the original designer as MSFC for the Apollo Saturn moon program. The dimensions are about 4.125 inches by 3.45 inches.
