Some of the middle era SV history books are quite good, although they cover the combination of hardware, software, and startup stuff.
Fire in the Valley,
Dealers of Lightning,
Where the Wizards Stay up Late by Katie Hafner,
Soul of a new Machine by Tracey Kidder,
The Dream Machine.
There are histories of Apple, Microsoft, and many smaller (and now gone) companies and/or projects.
Showstopper (Windows NT),
Insanely Great (Macintosh),
Defying Gravity (Apple Newton),
In the Plex (Google),
Hackers (by Steven Levy),
Ghost in the Wires.
More philosophical type stuff
In the beginning was the command line
Dreaming Code,
Coders at Work
There's many worthwhile books about the history and culture of programming and hacking not listed, but this might be a useful starting point.
