Signal is noisy as hell on both pins 72 and 71; freq meter says 2842.888 khz, I think this 4/3 of the actual clock due to some weird harmoinics (clock xtal says D214J1), that would put the clock at 21.32166Mhz which seems awfully low...
Maybe I need to run it through a bandpass or something...
EDIT: with the more low-tech non 10:1 probe i get a much cleaner signal, but its still showing as 2842.888khz for clock. now that i can see the waveform i see why its getting confused, there are two places where the slope is appropriate for triggering the edge sensor...
