I think André meant pins 1 and 6, which are ground and sense. It sounds like a dongle for Leaderboard Golf. Out of curiosity, what is the resistance of the resistor? A short circuit should work equally well. The only Commodore 64 interface that I know where the resistance matters is in the keyboard: if you make one of the wires connected to "shift lock" output '1' and the other output '0', you can distinguish between left shift and shift lock.
