This paper discusses a number of interesting applications of digital computers in the checkout of individual Saturn stages and in the prelaunch checkout of the complete Saturn vehicle. It discusses the concepts of automation in Saturn checkout, the unique two-computer mode of operation at the launch site and the operations of the high speed data link connecting the two computers. Also discussed are the functions of the computer while propellants are loaded automatically on one of the stages; the functions of the display computer in the newest and largest Saturn display system, and operations and utilization of the Digital Events Evaluator, the main recording device utilized during stage checkout.
