Make sure that the CDs you acquire, are the correct ones for your system.
You should have a set of system disks, for your own use, on hand at all times.
Having a Mac without them, is like owning a car with the hood welded shut.
Some info below.
Tiger is available for purchase at
The Apple Store (US).
Panther, ais no longer available directly from the
Apple Online Store, as
Tiger 10.4.x is the most up to date OS.
A
Full Retail Version, of the
Panther Install CDs, or a
Full Retail Version of the
Tiger Install DVD, can be purchased rather inexpensively, at some online Apple retailers, Amazon, eBay, AppleRescue, etc.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
