I figured out how to play sampled sounds on the IIci by writing directly to the Apple Sound Chip, and I found enough free ROM space to take a newer Mac's startup chime and retrofit it in there.
Normally the IIci's startup chime is synthesized by giving it which notes to play. Using this method it just plays a sound file, so it could be my voice or whatever else I wanted it to be. This startup chime, borrowed from most of the LC/Performa series, is a sampled sound completely different from the IIci's original sound.
At this point, I am able to play whatever sound I want at startup, as long as I can fit it in the chip! The era of custom Mac startup sound hacking has arrived.
