Software restore discs from the bygone G4 PowerPC Macintosh era. This software was for iBooks, iMacs, and Power Macintosh units. I was tasked with liquidating these discs. It is something I will regret to my very end of days.
Now that the entire Apple product line is Intel-based, PowerPC support has been summarily dropped from OS X. The PowerPC is dead. Long live PowerPC.
