Integrated Circuits First Used in Apollo Moon shot
21st December 1968
The Apollo Guidance Computer (AGC) was responsible for guidance, navigation, and control computations in the Apollo space program. The AGC was the first computer to use integrated circuit logic and occupied less than 1 cubic foot of the spacecraft. It stored data in 15 bit words (with one parity bit) and had a memory cycle time of 11.7 usec. Astronauts communicated with the AGC using the "DSKY" (Display Keyboard) shown on today's homepage. It used digital displays and communicated with austronauts using verb and noun buttons, and a two-digit operation and operand code.
The AGC and DSKY form part of The Computer Museum History Center's permanent collection.
