I found this in Brendan's lego technic model book. It's completely insane!A crane that runs on punch cards.Rad!

The next step up: Alan's book of robots controlled by BASIC programs on the Commodore 64. This book rocks, with robotic arms, a punch card reader, drafter and heaps more all using technic pieces hooked up to the old Commo.
