The advantage is that you can use spare lines on the EPROM to control such
things as direction/full,half stepping. I built such a device that drove 2
3-pole steppers in full or half step mode in either directon totally
independantly of one another.
It also only uses 2 IC's and you dont have to wire up counters.
