dagger01 said:Although it is true that not every Mac had it's own startup chime, and the chime did evolve over time, you are a bit muttled with respect to why, in what models and when.
The original Macintosh startup chime sounded different because it was based on an 8-bit, 22 kHz DAC. The chime remained pretty much the same until the 16-bit DACs and A/V models of Macintosh emerged in the early to mid-1990s. The chime was enhanced by adding more notes to the chord. The chord was still the same. The difference aurally between the standard 16-bit DACs in the Quadra series (and others with 16-bit DACs that came after) and the ones in the AV series was due to the DSP in the AV models. The DSP added spatial effects (reverb, sustain, etc.) to the chime. The other models lacked this DSP, so the chime 'sounded' different.
Since that time, and the time of the Power Mac, the chime has remained the same on all Macintosh models.

You seem to be forgetting that the PowerMacs 6100, 7100, and 8100 all had the Stanley Jordan plucked chord startup sound. I had a 6100 way back when...
