Today's guest is the famous NES PPU chip, RP2C07A by Ricoh. What's interesting about this particular sample is that it's very very dead. Many thanks to root42 (npub162r…ewqz) for supplying it!
As always, a short thread follows. Why not give this one a boost while you're here? :D

Note the die is oriented the same way Visual 2C02 has it: https://www.nesdev.org/wiki/Visual_2C02
