A circuit board from the Saturn V rocket, reverse-engineered and explained
Ken Shirriff writes on his blog:
In the Apollo Moon missions, the Saturn V rocket was guided by an advanced onboard computer system built by IBM. This system was built from hybrid modules, similar to integrated circuits but containing individual components. I reverse-engineered a circuit board from this system and determined its function: Inside the computer’s I/O unit, the board selected different data sources for the computer.
This post explains how the board worked, from the tiny silicon dies inside its hybrid modules to the board’s circuitry and its wiring in the rocket. This board was first studied by Fran Blanch in The Apollo Saturn V LVDC Project. Then EEVblog made a video about it. Now it’s my turn to analyze the board.
