Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).

If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:

MB427Z/A  Leopard 10.5.1 install DVD

MB576Z/A  Leopard 10.5.4 install DVD

MB021Z/A  Leopard 10.5.6 install DVD (single user)

MB022Z/A  Leopard 10.5.6 install DVD (5-user family pack)

After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update

The DVD should look like this

Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.

My experience is that whilst the early versions of Leopard had little, if any, support for OS 9 later versions are more flexible.

With my 733 MHz G4+ it is very practical to have the latest versions of OS 9, Tiger and Leopard on three separate partitions and select which to boot into via startup disk preferences or by holding the option key down at boot. OS 9 can be booted directly or used as Classic via Tiger but not as Classic via Leopard.

The only disadvantage I have found is that a direct boot into OS 9 may get around some OS X security but no more than booting from, an OS 9 CD, memory stick or single user mode.

its free
