This one tells the story from the precursors to time-sharing to PARC, using the figure of J.C.R. Licklider as a pivot, and was recommended by Alan Kay as better than Dealers of Lightning. I personally enjoyed both.
And of most of the participants at ARPA-IPTO and PARC. "Dealers of Lightning" was too much of the "hero's journey" trope, and also very confusing in sequence (even to those of us who were there). Both books missed how and why researchers cooperated and coordinated across projects, but "Dream Machine" is much more clear and generally more accurate.
Dealers of Lightning does a great job detailing his role in it all - https://www.amazon.com/Dealers-Lightning-Xerox-PARC-Computer... that along with soul of a new machine really capture the spirit of that 60s/70s generation of computing.
