  • Main Topic : Francois Rautenbach : The historical significance of the computer that took us to the Moon.

The Apollo Moon project was without doubt one of man's greatest achievements and spurred advances in many fields including avionics, telecommunications and computers. When NASA awarded the contract to develop the Apollo Guidance and Navigation computer to MIT, they could not have realised the impact that this decision would have on the world 50 years later. In this talk, I will explain how the Apollo Guidance Computer (AGC) kick-started the computer revolution and changed our world forever. He will bring along the real hardware, so we can see and touch bits of history.
