1968 – Integrated Circuits
Used in Moonshot
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 microseconds. Astronauts communicated with the AGC
using the “DSKY” (Display Keyboard). It used digital displays and communicated
with astronauts using verb and noun buttons, and a two-digit operation and
operand code.
The AGC and DSKY from
part of The Computer History Museum permanent collection.
2000 – Child Internet
Protection Act into Law
President
Bill Clinton signs the Child Internet Production Act into law. The law is

defined as material. This included sexual acts or nudity.
