For those that read the comments first, this has nothing to do with rockets. :-) It's interesting, though, that the rockets have a similar relationship. The Titan computer was a scaled-down version of Atlas, and the Titan rocket was a fallback in case the Atlas rocket didn't ship on time.

An Atlas was the first computer I used. At school in about 1970 we had some programming lessons and we sent our coding sheets (in FORTRAN) to be run at the Atlas Computer Lab near Oxford. Those lessons were probably responsible for launching my career in software which I'm still enjoying today.

I am simultaneously glad that I did not have to live through such times where computing power was so scarce, and sad to have missed such an exciting time. It is always fun to read these stories, though.
