For those interested in the idea of decapping and magnifying to reconstruct gate layouts, this story will be of interest.
"A team of three people—Greg James, Barry Silverman, and Brian Silverman—accumulated a bunch of 6502 chips, applied sulfuric acid to them to strip the casing and expose the actual chips, used a high-resolution photomicroscope to scan the chips, applied computer graphics techniques to build a vector representation of the chip, and finally derived from the vector form what amounts to the circuit diagram of the chip: a list of all 3,510 transistors with inputs, outputs, and what they're connected to. Combining that with a fairly generic (and, as these things go, trivial) “transistor circuit” simulator written in JavaScript and some HTML5 goodness, they created an animated 6502 web page that lets you watch the voltages race around the chip as it executes. For more, see their web site visual6502.org. "
And they say they're looking for hardware.
"We're always on the lookout for interesting classic hardware to study, especially rare hardware in danger of being lost or hardware that no longer works. Broken circuit boards and damaged chips are perfect for our methods which, ironically, involve completely and utterly destroying things in order to preserve them. We create accurate digital models of hardware - models that function exactly like the real thing - and by sacrificing just one single artifact, can create a digital model that will live on long after the last of the original hardware is gone."
