Well I'm in Adelaide Australia, and the chances of finding a serial programming cable is... slim. From my reading the WP-34s book [reminds me of the PPC ROM book - big & comprehensive] there's a USB adapter board, but I can't find a website that sells it & several searches of MoHPC have come up "dead link". So the search is on, for another way to link to the calculator...

The guys at Dangerous Prototypes make several projects that each require assorted serial comms protocols. They came up with a project to talk to "anything" while it was still a jumble of parts on a breadboard. You can read about it at:

As for my own attempt: has a Digilent PMOD connector, and uses TI chip TCA8418. Plenty of blank space left on the bottom - the next version is planned to have USB battery charger. I'll try a Dropbox photo link.
