Really interesting about this to me was the audio sample rate of the original Mac line, and especially the unusual refresh rate — I would have expected a straight 60hz refresh due to US wall current, and 22050Hz audio. Missing from this reconstructed sound is the satisfying click of the power switch and the brief pre-sound of the circuits springing to life just before the beep (and of course, the quality of the tiny, tinny, speaker itself). Happy memories!
