I’ve never had occasion to write a trigger warning for a TidBITS article before, much less an ExtraBIT that points to someone else’s article, but Stephen Hackett’s Mac Chimes of Death piece on 512 Pixels deserves one. It provides clips of the sounds that various classic Mac models played when they were unable to boot. I didn’t think much about it when I played the first one, but by the end—and thanks particularly to the terrifying car crash sound made by the Power Mac 6100—my heart was palpitating. That said, I quite liked the ominous Performa chime of death, which I had never heard before. These clips may start you on a simple walk down memory lane, but watch out for the flashbacks.
