The book he references ( https://www.amazon.com/Making-Prince-Persia-Jordan-Mechner-e... ) is a collection of journal entries he wrote while making the game. It's been about ten year since I read it, so the details are fuzzy, but it's a very raw retelling of the process of making a game basically entirely alone and before the internet. I'd strongly recommend it to anyone who writes software.
Regardless, very interesting and inspirational, they were really pioneering times.
