The material was all proprietary/NDA and I don't think it's ever been shared publicly, sorry.

The main point I wanted to make with how I became the CPU expert was not actually the "reading multiple times" in order to deeply understand it (although that was important) but rather the fact that I chose to become the CPU expert rather than having it assigned to me.

It was one of many times that I became the acknowledged expert of some area, and perhaps therefore in charge of that area, just by working hard in that area until I was "obviously" the expert.
