Computer Time Travel: How to build a microprocessor from transistors Hardcover – 31 Jan. 2017

my first machine was a ZX80 back in 1981. since then ive gone on to work in IT for a quarter century. this book gives me a greater understanding of what goes on under the covers.

This book takes you back to the very basics of computer CPU design, right down to the transistor level. It's written in a logical order that steadily builds upon the previous chapters are you progress through the book. The one citicism I have of this book is the print quality of the schematics is terrible. The diagrams are very faint and very difficult to read. I did reach out the author via their website to see if it was possible to obtain a PDF version or something similar, but unfortunately I received no reply. Whilst the book's technical content is good, the schematics made following along in parallel a real chore for me.
