I'm getting into the WP34s (kind of late, I know). And I thought I document my temporary programming cable. Here it is:

   

It's not much. Basically, it's a CA-42 cell phone programming cable with the end cut off. I soldered the three wires (TX, RX, Gnd) to a breakaway header and used some Cat 5 wires to contact the programming pads. These CA-42 cables are quite cheap from China. I had several from another project. They use the fake Prolific chips and have a 3.3 V output. These chips can be a problem if you don't have the right driver, but I've had good luck with the driver mentioned in this post:

It is kind of fiddly. All this is temporary. I'm ordering the parts to build Katie Wasserman's cable connector. But I thought I'd show how simple it can be. I hope the pictures show up. I haven't tried this before.
