It was about as powerful as an Apple II.

These gave the Astronauts ‘flight’ control.

So you see, these 4 computers were very powerful & did an amazing job.

Here are some facts for you to think about.

It took 350 people to design the software for  Apollo 11

IBM designed & built most of the computer systems.

The fastest computer today is 146 million times faster.

Your phone has over one million times more memory.

Computers flew most of the mission, not the astronauts.
