Check out The Difference Engine by

William Gibson and Bruce Sterling.

Victorian setting, steam powered tech, mechanical computers.

This book is thought of as the opening shot of the steam punk style.

I'd be interested in a list of cyberpunk books. I only have a few so far.

"Neuromancer" is the cornerstone book....IMHO

The "Sprawl" trilogy began it all :

"Neuromancer"

"Count Zero"

"Mona Lisa Overdrive"

PKD was by all means inspiration to the idea behind "Cyber-punk" (I have read D.A.D.E.S. at least 5 times and have an album built around the ideas in it) but Gibson truly fused Dick's Dystopic character with the classic "hacker" in a number characters (staring with Case from "Neuromancer" and the more streetwise "enforcer" type (Molly from the "Sprawl"trilogy )

Neal Stephenson

"Snow Crash"
