If you’re interested in the systems behind Apollo, go find and read “Digital Apollo”.

It goes all the way through the project and describes in good detail everything, how they developed the control systems, the computer hardware, how the software was designed, how they implemented one of the first real computer systems project management, all the interactions between astronauts/test pilots who still wanted to “manually fly the lander”, the political back and forth between competing teams, the whole thing.

It’s a great read if you have a technical mindset.
