I have two L293Ds and one is in the default DIP socket on the actual board, and the other is external. The external chip, I wish to control four geared motors (they are GM10s if that makes any difference) How do I go about doing this? I already purchased these two radioshack products:

and

What ports do I use on the chip? Is this even possible, to control 4 motors with one chip? How do I control these if it is? And where do I connect them (outputs, voltages, grounds... etc)
