Tiger install DVDs are in short supply. Tiger is no longer available at the Apple Store *but may be available for $129 by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753)*. For other sources, do a Google search for
MA453Z/A (10.4.6),
MA190Z/A (10.4.3) and
M9639Z/A (10.4) . Also look on eBay. Be sure & buy a retail version (black with silver X)
and not a model specific version (gray) (See
Can I use another Mac's system restore disc on my Mac? ). Expect to pay (possibly a lot) more than the Apple list price of $129.

After you install the base 10.4.x, update to the final Tiger version 10.4.11. Here's the link for the 10.4.11 combo update

Be sure to select Preserve Users & Settings. Also, repair permissions before and after the install.
