        Hmmm, too much work for too little trouble ;o)

        So tell me, HOW to do that? These are fairly common in Brazil - people=
 around here is crazy doing plotters with old matrix printers. But how to=
 get 0.1mm repeatability? Maximum I got was something around 1mm!! :oP

        The Yellow Box will be the size of the dip switches, eh? ;o)

        Well, this is not a hard thing to do. Have you tried the lutcho's pages?=
 Full of support for personal PCB plotters and engravers. I'll look for the=
