Restoring a 6502

Restoring a microchip is much like any other kind of restoration, just on a smaller scale. This website details how a circuit board found in a barn (literally stinking of cow manure) contained a rare early MOS 6502 CPU from May 1976. The 6502 was extracted from the board, cleaned up and still works!

The 6502 is one of the iconic early CPUs of the microcomputer revolution in the 1970s being first produced in 1975, powering the likes of the Apple II (my IIe seen below). Amazingly the CPU is still produced today and used in many embedded systems.
