Time to make a map of where everything is before hooking up the oscilloscope. I find this ends up being a huge timesaver. Actual silkscreen labels on everything is even nicer, but often there just isn't room for it all to fit.

This board has /IOSEL wired up and the VGA outputs used as debug pins -- using it to develop disk or IO interface glue and better understand the timing of everything.
