How powerful was the Apollo 11 computer?
With all the buzz about the 40th anniversary of the Apollo 11 Moon landing I got to thinking, how powerful were the computers that "took us to the Moon?" It turns out, they were nothing short of amazing. If you've never had a nerdy bone in your body, feel free to skip this post. But, if you ever laid on your back under the stars and thought about Mercury, Gemini, Apollo or the Space Shuttle, read on and see if you're as geek-struck as I was researching this.
Comparing the Apollo Guidance Computer to an IBM PC XT
My first thought was how did the Apollo computer compare to the iPhone? It turns out that's a really tough comparison to make. The iPhone is so advanced compared to the computer used in Apollo's guidance system that it's hard to believe they both came from the same planet -- at roughly the same period in time when viewed in contrast to man's time line on Earth. To really make a comparison that makes much sense it's much easier to look at the home computers of the late 1970's and early 1980's.
