Maybe this is a 4 wire stepper? If it is a 5 or 6 wire stepper, try this: All the emitters go to PIC ground, along with the negative of your wall wart. Positive of the wall wart goes to the common(5 wire) or commons(6 wire) of your stepper. The four collectors each get a stepper lead. Put resistors between PIC and base! Let's say 220 ohms. This doesn't give you snubbing, but depending on the size of your motor you might get away with it. If your stepper is a 4 wire forget what I said, it won't work because you'll need bipolar drivers. -Bob http://www.bobblick.com/
