Man, I would have given up some serious allowance money for this back when the Apollo program was active.

Reading through the descriptions of some of the flight and launch control systems gives me a high level of respect for the software folk responsible. Sure, the systems were simple compared to today, but there was no room for any of the sloppiness we see passed off as "software engineering" in the interim years. "Mmm, I'm not entirely sure about that launch abort method, but we'll check it in, see if test finds anything."
