*********************
This chip is a stepper motor driver chip'IC'is made by
Motorola SAA1042 or SAA1042A
You looked in the wrong book,check out Motorola's book not TTL cook book.I'm
sorry that I can't provide you with the pin out as I don't have my books close
at hand,but just look in Motorola's book you will find it there.
