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...

First release of the APU dissection:
Broken decimal mode in the 6502 core is not covered,
factory test area is not covered.

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.
