Ah perfect - I'll go over this tomorrow after work and assuming I figure it out I'll photo the results for the collection.

I mostly lurk (sorry!) but I was wondering if someone had a wiring diagram for PU-20 US/NTSC board? I've probed and figured out where the gate/data signals are, but I'm not sure where to start to find the SUBQ/SQCK signals required for the arduino sketch.
