I have a Powerbook G4. It is the perfect machine for running the emulator SheepShaver, so that I can play old mac games that run in System 8 and thereabouts. Unfortunately, the sound on some games I've been attempting to play hasn't been working, and I've figured out the problem: I am missing the Apple extension named 'Sound Manager'.
(For those who don't know, Sound Manager is the old mac equivalent of sound-card drivers.)

As such, I've been looking all over the internet for Sound Manager and haven't found it. Even Apple has removed it from their old-software download page!
So, I have come here, to Emuparadise. Can anyone help me with this? I need a copy of Sound Manager, preferably version 3.anything but if another version comes up I'll take that too and see if it works. Regarding where to find a copy, this extension was often included on old Mac CD-ROM games so that people without it could install it. (I know there's a copy on the Mac CD of King's Quest 7, for instance).

Thanks in advance.
