I personally would not try feeding a signal into the XIN pin. Crystal
oscillator circuits would (I think) be fairly sensitive.
Can you borrow a CRO? I hooked up mine to the IIgs clock chip and got
a lovely sine wave on one of the XIN/XOUT pins (the other was a
slightly lumpy sine wave).
With the IIgs off the 1Hz pin was not active.
