Visual 6502

The guys at made an amazing simulation of the real 6502, at the hardware transistor level! So finally no more secrets about the 6502!

Working from a single 6502, they exposed the silicon die, photographed its surface at high resolution and also photographed its substrate.  Using these two highly detailed aligned photographs, they created vector polygon models of each of the chip’s physical components – about 20,000 of them in total for the 6502.  These components form circuits in a few simple ways according to how they contact each other, so by intersecting our polygons, they were able to create a complete digital model and transistor-level simulation of the chip.
