Referring to the controller port...
What signal appears on the wires when you write a zero in the least significant bit to $4016? For a 1 in the least significant bit, I think it's a double width pulse, and for a read of $4016, I think it's a single width pulse. Does anything appear on the wire when you write a zero?
