Or a line that shouldn't be floating but is mostly managing to be in the right state just from stray capacitance. I'd say, though, from looking at the thoroughness of your work, that none of this is likely. But you asked for w.a.g's. Incidentally, that is a very cool project. I have been dreaming of / wishing for such a thing for a very long time. The FPGA is good evidence o= f why we've had to wait so long. Or of how far I would have gotten had I tried it. Your FAQ maybe should mention if you've ever considered making the hardware available.
