27C3: Reverse engineering the MOS 6502
The MOS 6502 CPU, which was designed in 1975 and powered systems like the Apple II, the Atari 2600, the Nintendo NES and the Commodore 64 for two decades, has always been subject to intense reverse engineering of its inner workings. This talk by Michael Steil presents the way from a chip package to a digital representation, how to simulate transistors in software, and new insights gained from this research about 6502 internals, like “illegal” opcodes.
This talk was recently presented at the 27C3 conference sponsored by the Chaos Communications Congress in Berlin, Germany.
The presentation is in six parts, part 1 above and the following:
