So they signed a deal to only allow their pretty speakers to work with the pretty Macs of the time... lame.

The official users guide (http://www.harmankardon.com/images/media/ISUB_OM_EN.pdf) Says its Only for the 350mhz imac computers and faster, and not the PowerMac G3, G4 or Powerbooks.

That's a very particular device and I'm highly confused as to why they would do that. I have a 350mhz G3 imac with OS 9.2.2 if you want me to fire it up and look for that driver. Maybe we can change an identifier in it or something to make it function on other macs.
