Reinstalling Classic on PowerBook G4 running Tiger
I use my old powerbook G4 15" 1.5Ghz to run important business software that only runs in Classic. My hard drive died however (flashing folder with ?mark). All attempts to revive the old hard drive failed, so I bought a new internal hard drive and installed it myself. I found three old OS disks lying around (OS9, OS 10.1.3 and OS 10.4 tiger). I chose to install Tiger and all is well, except I don't have access to Classic, which was the whole point. I wish I knew if either of these three disks was the original system software for this particular Mac, but I can't remember. Seem like if I use the original disk, it would include Classic with it's install.
Basic question is: How do I get Classic running again on this PowerBook? I do have an old G4 Titanium that still runs. Can I pull an OS9 system folder off of that? Can I use my OS9 disk somehow?
Any help is greatly appreciated. I'm not a computer whiz, so explain in layman's terms please.
