major arpeggio, followed by three or four notes, with slight variation depending on the model of the Macintosh. The PowerBook 5300, 190, and 1400 use the second half of the 8-note arpeggio as found on the Quadra and Centris models, or the entire death chime if the error occurs before the screen lights up. The Macintosh Quadra 660AV and Centris 660AV use a sound of a single pass of Roland D-50's "Digital Native Dance" sample loop, and the NuBus based Power Macintosh models (including 6100, 7100, and 8100) series use a car crash sound. The Power Macintosh and Performa 6200 and 6300 series, before the screen comes on for these models, along with the Power Macintosh upgrade card, use an eerily dramatic 3-note brass fanfare with a rhythm of drums and cymbals; the former plays the 8-note arpeggio instead when the screen is on. The pre-G3 PCI Power Macs, the beige G3 Power Macs, the G3 All-In-One, and the PowerBook 2400, 3400, and G3 all use a sound of glass shattering; these models do not display a Sad Mac icon. Since the introduction of the iMac in 1998, the Chimes of Death are no longer used in favor of a series of tones to indicate hardware errors.
