Perfect board with every chip working. Salvaged everything off of it and the cartridge port repaired one of my silver labels that had bent pins. Also it had a 6581Ar4 Sid chip from 1994 in it that is super rare and sounds FAT.

It is pretty sad. It is a 450425 board revision and in my experience the best board in terms of video clarity and construction quality. It was the last board revision before they went to the short board c64c, "C" standing for "Cost reduction". Should have been CQ for Cost and Quality.
