Voici comment l'ordinateur d'Apollo, appelé en anglais Apollo Guidance Computer (AGC), a façonné le monde d'aujourd'hui, bien qu'étant des millions de fois moins puissant qu'un smartphone de 2019. It was hogwash to many and created a great deal of doubt. So, engineer Ramon Alonso came up with a simple display keyboard, named the “DSKY”, where two-digit numbers represent programs, verbs and nouns. The CM housed the computer in a lower equipment bay, near the navigator's station. When the design requirements for the AGC were defined, software programming techniques did not exist so it had to be designed from scratch. The navigational and guidance data obtained by the IMU flows to the guidance computer and is used along with data from the computerized space sextant to provide optimal control of the spacecraft.
