Re: INCONSISTENT STEPPING - WIERD SITUATION

Jeff,

Check your DIRECTION signal. My bet is it does not meet TTL
requirements when it has to carry opto LED current.

Try running things with the "common +5VDC" input jumper option. Get
your +5VDC from pin 1 on your game port. Your LPT1 port probably
can't source the required 16 mA. It will sink 16 mA though.
