Hallihallo!
In irgendeiner Computerzeitschrift stand mal ein Bericht über die Computer, die bei den ersten Mondlandungen der NASA verwendet wurden. Kennt jemand eine schlaue Internetseite zu dem Thema?

Hi Jörg,
hier ein Auszug
DIGITAL COMPUTER
The onboard digital computer is a binary, fixed point, stored program, general purpose, digital computer which provides executive functions, computations, timing and signal processing for spacecraft guidance and control. The Gemini computer has a memory of 4,096 words (39 bits/ word). It is random accesswith a non-destructive readout. Division of the memory into three syllables provides flexibility in instruction and data storage location assignment. It can add, subtract, and conduct a transfer operation in 140 microseconds. Multiplication (full precision) is accomplished in 420 microseconds. Division (full precision) is achieved in 840 microseconds. Multiplication and division may be programmed concurrently with addition and subtraction or transfer operations. The clock rate of the Gemini digital computer is 500 KC arithmetic bit rate; 250 KC memory cycle rate.
