mcpublic writes: The MOS 6502 microprocessor is famous among the vintage computing and classic gaming crowds. It was used inside the Apple II, the Commodore 64, the Atari 2600, and the Nintendo Entertainment System (NES). Need I say more? In 2010, the chip's 35th anniversary year, reverse engineers came out in droves and published more details about the 6502 than ever before—yes, really! For the assembly language crowd there is Michael Steil's excellent 50 minute talk on the 6502's architecture and instruction set delivered at 27C3, the video posted just yesterday. Or maybe you just want a quick read on 6502 history and some awesome reverse engineering efforts? Check out Russ Cox's blog. But if you are looking for the original 6502 netlist, accurate down to the last undocumented instruction, or want to run an animated 6502 chip simulation in your browser, you'll definitely want to visit Greg James, Barry and Brian Silverman's visual6502.org web site. These pied pipers have attracted an enthusiastic following of like-minded engineers who are now photographing and disecting even more classic chips.
