NES PPU dissection

As promised, I did a new revision of my NES PPU schematics after finishing the 6522 dissection.

While waiting for new material from Frank, I'm trying to dig a bit into the NES APU again...

Thanks to all who make these chip dissections possible.

Since we had some 6522 related material in this thread,
I'm posting a link to the 8520 dissection here.
