NOTES

(1) Second generation PPC Macs are machines such as 7500, 8500, etc. that come with a PPC 603, 604 or 604e CPU daughtercard.

(2) Hardware tweaking for exclusive piping to a set of earphones/external speakers means that one needs to pull the connector on the internal speaker, otherwise output will be heard from it even if the earphones/speakers are connected. What's happening here is that the circuitry to shut off the internal speaker isn't activated, therefore one hears stuff from the internal speaker.

Burgundy

  • Most of the mutes don't work, or their state cannot be saved.
  • Volume sliders for the built-in stereo speakers and for the headphones are reversed (headphone controls the speakers and vice-versa).
