but both buttons are not wired up equally at the Amiga end, buttons 2 and 3 go into Paula, buttons 1 go into one of the CIA chips. we have to think about the circuits, not just isolated voltage potentials. i don't know enough about electronics. How exactly the multiplexer is implemented in the MD pad might also be important - is there any connection at all without a power supply? Bear in mind Amiga only cares about a connection to ground to detect the button press.
