"There was a time, not too long ago, when the typewriter and notebook ruled, and the computer as an everyday tool was simply a vision. Revolution in the Valley traces this vision back to its earliest roots: the hallways and backrooms of Apple, where the groundbreaking Macintosh computer was born. This book traces the development of the Macintosh from its inception as an underground research project in 1979 to its triumphant introduction in 1984 and beyond." "Through period photos (many published for the first time here), original sketches, and Hertzfeld's firsthand accounts, the book reveals what it was like to be there at the birth of the personal computer revolution. The story comes to life through the book's portrait of the talented and often eccentric characters who made up the Macintosh team. Now, over 20 years later, millions of people are benefiting from the technical achievements of this determined and brilliant group of people."--Jacket.
