Born of a soldering iron and some unfaithful screws
I know my knowledge of the American nineteenth century is like most people with the Russian Futurists, but can somebody explain to me why it still took me until this afternoon to hear about John Murray Spear's New Motor—a mechanical Messiah built by Spiritualists in a barn in Lynn, Massachusetts, mystically birthed by one of its female followers and eventually smashed to pieces by an honest-to-God angry mob? Steampunk, give it up. You can try on all the brass and goggles you like: actual history was weirder than you.

Interesting idea! If you write it, I'd be interested to read it.
As a kid I briefly thought of writing a story where it turned out that automobile mechanics and people like that actually had to do magical rites as part of repair work, but I quickly realised it wouldn't fly because suspension of disbelief would be impossible--too many people can do a certain amount of work on these things themselves. There's a lot more potential with computers, although maybe I say that because I can't programme to save my life. ;-)
I'm thinking Tom Holt had a throw-away line or two in one of his novels (Who's Afraid of Beowulf? or something like that?) where an evil sorcerer from the Viking Age who was still living in modern times revealed that he'd actually invented computers as part of his plot to take over the world. That still leaves a lot of room for you to run with this.
(a lot of writers described such a world where magic evolved instead of technology... Harry Turtledove comes to mind)
Indeed. Poul Anderson wrote a couple of fun ones as well: Operation Chaos (1971) and Operation Luna (2000).
