I hadn't noticed this on here. Sorry if this was posted about before. But I ran across this because of the recent post on the tia internals. This group reverse engineered the TIA and the 6502. Not by studying what it did, but with acid. They used sulfuric acid to melt the chip, and took photos of the internals of the chip. Then they converted these images to a netlist, and simulated the chips. They tested them by running an atari rom, with the simulated chips. On their website you can see the internals of the 6502 and TIA. They even have a Java based simulator, where you can watch the voltage in the transistors on the 6502. If someone wanted to create a TIA or 6502 with modern chips, these netlists could be used to create a nearly 100% accurate copy of the chips. This is probably the coolest Atari news I've heard in years.

The virtual 6502 was posted before, but the TIA is new -thanks for posting it.
