Hi Katie,

very nicely done! Thanks for sharing. I think this is probably most interesting for people who do not wish to modify their calculator with the USB board. Sorry there is no link for ordering the PCBs, just email to: h dot pott at gmx dot net. Originally the board was intended to replace the PCB in the HP cable, so the cable could directly be connected to the USB port without an RS232 adaptor. For that purpose it seemed best to reuse the original pushbutton - hence I don't have any of those right now. But if there is an interest in these boards I can order some buttons and maybe even make the connectors. Unfortunately I don't think I can buy beryllium copper in Germany.

Harald.

Harald's board is slightly smaller then the one shown on your photo.
