HP-41 PCB's pictures (for the HW guys out there... ;-)

[Diego Diaz]

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.

Have fun!!

P.S. It's some 2Mbyte!!

Thanks for the pics, it's always interesting to see the differences between models.
