You could use a atmel 90s2313 chip it outputs a very fast stepping
signals, I've used it in the past, you can use free bascom for
programming in basic language.
The only thing I could not do on the code was implementing the ramp
up or down necessary to achive top speed at the motors.
BTW if anybody knows howto do it in Basic( ramp up or down)reply to
this.
