I knew a retired couple near where I lived growing up who, I found out later, were software programmers on the Apollo Program. Quite possibly worked in that lab. The husband passed away soon afterwards, and I never got around to asking the wife about her experiences (they both worked for the program!). But it was really cool reading about how the core software was written.
