What atari history book are you talking about? I would be interested in that too but both of your links are to the Bagnall book on Commodore.
I am glad to see the MIT book is coming. Preordered it when I first heard about it. So few books on Atari and Commodore from those days and with so much computer history being written with them left out these are the only way to keep the memory of their contributions alive.
Sorry here's the link
