Today is the 46th anniversary of the first time we walked on the moon. The story from Time Magazine below gives you an interesting insight into one of the key pieces of technology - The Apollo Guidance Computer (AGC). To get a bit of perspective, the AGC had 64 kilobytes of memory which was a huge amount for that time. Today, a typical iPhone might have 32 gigabytes of memory which is 32 million kilobytes or the equivalent of 500,000 Apollo Guidance Computers. To play Bejeweled on that iPhone you need 65 megabytes or about 1,015 Apollo Guidance Computers. Your microwave oven’s control system has a lot more computer power and memory that the AGC that guided the astronauts to the moon.
