An excellent book about the guidance computer on the Lunar Module, is Sunburst and Luminary. https://www.sunburstandluminary.com/SLhome.html https://www.sunburstandluminary.com/SLhome.html It describes in a very entertaining style about building testing and editing the software and hardware of the Apollo program. It includes a lot of commentary and anecdotes about the era and life style of many of the program's engineers, designers, pilots, technicians, etc. Very recommend.
