Ha! Okay, ya got meh! But! IN THEORY You could still construct a processor out of electromagnetic relays (springs, contacts, leads and solenoids only), if perhaps your goal was to never exceed 100 Hz. (...at first I was going to point out http://www.bigmessowires.com http://www.bigmessowires.com but it turns out that beyond the wire wrap connections, he's still using modern semi-conductor packages)
