Anyway, the cable I have for the USB version is just a hacked up one for the serial version. It should be possible to modify the old cable by adding a DPDT switch and a USB connector so that it would work for both calculator versions, as only 2 pins need to switch.

We're talking about the same cable as one uses for updating the WP-34S (or 20b/30b/12c+/15c+) right?

DPDT switch?

Right.

The DPDT (double-pole, double-throw) switch would be needed to swap the both data lines between the USB interface and the existing RS232 level converter. I don't think that there is enough room inside that little black shell for such a switch, so it might require some repackaging.
