    @ Jerson, I agree completly!!

    Short answer - machine controller

    The project is an interface between PC parallel port and up to 10 axis of stepper/servos with 2 inputs per axis for limit/home switches. Also a couple of relays for some high power stuff.

    So the parallel port itself uses 12 pins, then each axis is 5 pins. so thats 62 right there. I have run out so I must have forgot some things.
    It will use 2 50 pin connectors to plug into 2 5 axis cards and carry all the needed stuff to them. Full digital setup for the stepper drives on these cards.
