Re: Changing Parallel Port Pins

I remember someone using this drive amp with the EMC but can't remember 
who or when -- might have been about six months ago.  Look in the 
archive.  I seem to remember something about a mechanical/electronic 
solution, like cutting the traces and jumpering or putting a cnckits.com 
breakout board in between.  You might also post this to the 
cad_cam_edm_dro and cad_cam_emc lists at yahoo.
