HP-41 PCB's pictures (for the HW guys out there... ;-) Message #1 Posted by Diego Diaz on 15 Sept 2005, 5:30 p.m. Hi Hope some of the Hardware "maniacs" here enjoy this *almost* complete collection... just for fun, not much real use indeed, but it can be used as a time reference as the PCB's are shown in chronological order. For the sake of precision, the initial CV shown in the picture is the four layer version PCB, there is a newer two layer verison with identical components footprint (except for the bender soldering pads) but with a more dense track pattern. http://www.clonix41.org/Maintenance/hp-41_PCBs.htm Have fun!! Diego. P.S. It's some 2Mbyte!!
