Will a parallel port drive this?

    I'm wondering if a standard pc parallel port will drive this device
    with "MOS" level inputs. It's a forced feed back controller for Happ
    Controls Active Steering Wheel. Will the voltages match up?

    Motor Control PCB 50-2000-02
    1. J1 - 8-pin header – Optically Isolated control inputs. 14MA, active
    low current sink.
    Pin Function
    1 +5vdc
    2 Circuit ground
    3 Key
    4 Torque input A (least significant bit)
    5 Torque input B
    6 Torque input C
    7 Torque input D (most significant bit)
    8 Direction input

  2. It should be no problem, we've been driving stepper motors using
    driver chips and a parrallel port via a RABBIT microprocessor in class
    so I think that what you want to do is mostly the same and should work
