Good question, and the answer is yes. I have tested for continuity, the clock line thruout the board is indeed connected to the pin in question on the microcontroller.

Not sure if it’s really a bug. I think it’s probably more like a hack. Many people have been using this thing since 2009, and the only complaints I found was about how heavy this thing is or how much heat it generates, both of which seems to be by design.

My case should be somewhat unique, due to the history of unsupervised mod done to it.
