Robert,

the small pcb should be able to be removed just by loosening some
terminal screws. At least it looks that way in the photo.

Of that is the case, take a photo of the back and the chip and put it
in the CNC-pics group (CCED, this group, has the files section locked.)

I really think you are just a simple circuit away from step and dir
with a small add-on board.

Also, I hope you got a few of these.

Dave
