How can I install Mac OS 10.4 (Tiger) on a Mac without a DVD drive?
If you are looking for old MacOS Versions you can go to the download site of https://developers.apple.com and get an old version of MacOS. I didn't see your particular 10.4 Version, but I did see 10.3.9 and 10.5 Leopard. 
The different downloads can be found here. You can download them to your desktop and install it.
