Not really sure where I should put this, but I figured some of you might find it interesting

Shame the chip they likely decapped and examined wasn't pulled from a NES. Might be binary compatible but from what I understand the 6502 used in the NES wasn't 1:1 identical with that of what was used in the Apple][, et al.

See:

2A03, just not traced out yet by them. The PPU also is being decapped I believe right now and being photographed. The lockout is already decapped and figured out. Everything is there for somebody who wants to remake them in bulk or study how they work, etc. And the NES's 6502 core is exactly the same as the MOS6502, except the BCD mode was hard wired not to work on it, since that was the only thing patented on the 6502.
