Recent iMac purchase with 10.8.5 blew up some DVD Training tapes I sometimes still use. I have tried to get my old Powerbook (1025) working just to view these tapes. The hard drive is toast but I can load the system from an old Firewire peripheral. I need to get to Quicktime 7.1 to view the tapes and for that I need 10.3.9. Problem is 10.3.9 won't load if a peripheral Firewire drive is attached. I would rather not partition my iMac drive and run 10.8. Any hope? I am recently retired so I don't want to throw a lot of money at this problem.
