The pdf is much easier to read for me too.

I think 2v per division would be a good compromise, but make sure the x10 settings on the probes match the settings on the scope.

Also I think change the horizontal timebase setting, to show more memory cycles. Maybe 10 to 20 us for the width of the plots.

There should be enough memory reads from prom to show some pulses correspond between inputs and outputs, but some of the plots show no match at all, which makes me doubt the buffers are working.
