The Computer Connection
A group of idealistic immortals enlists the aid of Dr. Sequoya Guess, a Cherokee physicist, to take over Extro, the super computer that controls all mechanical activity on Earth, to rid the planet of all repression, but, instead, Extro gains control of Dr. Guess, who now must be eliminated. Reprint.

Not as good as The Stars My Destination and quite hard to read, but the core story is pretty cool.
