The whole point of the Visual6502 effort was to reverse engineer older processors by slicing up the die little by little and taking pictures of the die and using image recognition to convert them into transistor circuits. Then they simulate it accurate enough to be operational. http://www.visual6502.org/ http://www.visual6502.org/
