Also, a >source for a couple of big steppers? Well, my recommendation is, of course biased. My company makes a good 1.75 inch square module (15 pin SIP package) that will drive up to 500mA per phase with full features (half step, auto or external step, free spin, etc.); alternatly we sell just the stepper chip that can drive four MJE3055T power transistors for very large motors. Datasheet with hookup schematics are on our web site at http://www.netins.net/showcase/elab The stepper IC is the EDE1200, in the 'Integrated Circuits' section. As for driving it serially, put one of our EDE300 PC Interface ICs on the front end. It will control up to 4 steppers depending on how much control you need over them. A datasheet for it is on there as well. As for stepper motors, try B.G.
