"Am I the first person to discover this?" is a tricky question when it comes to classic Macs, some of the most pored-over devices and boards on the planet. But there's a lot to suggest that user paul.gaastra, on the 68kMLA vintage Mac forum, has been right for more than a decade: One of the capacitors on the Apple mid-'90s Mac LC III was installed backward due to faulty silkscreen printing on the board. It seems unlikely that Apple will issue a factory recall for the LC III—or the related LC III+, or Performa models 450, 460, 466, or 467 with the same board design.
