The 'tech' comparison in TFA only applies to computer hardware for the guidance computers. I'd be keen to know more about the engines, the fuels, the materials, the construction techniques, etc.
Personally, I'm much more interested in how problems were identified and overcome than how The Trench was organized and how astronauts liked to speed in their corvettes.

I have the book! While it's a worthy book and I enjoyed reading it, it is not written by an engineer or scientist and comes from a lay perspective. There are a few great tidbits in it, like how to determine the amount of fuel left in a tank at 0 gee, but you had to read a lot of pages to find those nuggets.
* Stages to Saturn
* Digital Apollo
* The Apollo Guidance Computer
The last one may be too boringly technical. Some parts can be a slog even for me who breathe that stuff.
That's all non-computer stuff.
