Mac Pro and many other older machines, Mac OS X (10.6.6)
Did you ever find a copy of this OS?
In a similar boat here, the only way I can get all of the software/drivers that I need to work is to run OS 9.1 - so I am trying to replace my 2x1Ghz G4 running 9.2.2 with a 733MHz G4 DA... bought one off of eBay because the guy said he would include the 9.1 disc (even though it was running 10.4), well, after I paid he wrote and said he couldnt find the disk. I called Apple and they said that I could get a replacement disc from them (for $12?) so I told the guy I would take it anyhow (and he said he found the disc) ... well, got the computer and the included disc was for an iMac, no big deal, called Apple - and this time the person says that they no longer carry that OS - and there's nothing he can do (this was like 5 days later so I can see how things would change). So now I have a whole lot of crap that I can't use - and really no where to turn ... I have been looking for this disc for months now.
Have you checked with a nearby Apple User Group? Most large cities and universities have one -
Mac OS 9.1 for PM G4 digital audio
