OT, large stepper drives

From time to time the question comes up about the driver electronics to
power a larger stepper motor. I have run across a deal on some serious heavy
duty industrial type bi-polar, current limiting drives that interface very
nicely with a Stamp. To drive them you just toggle a pin high or low to
determine the direction of rotation and then send a single pulse for each
microstep you want the motor to move in that direction.
