This is where I wish my Sybex 'Programming the 6502' wasn't buried in the garage. It's probably been nibbled away to nothing by Silverfish by now.

So according to my poor schematic reading, input to Pin2 on the 6502 comes from Pin23 J4.

Is that right? Not sure it can be as there's nothing plugged into J4.
