downgrade Mac OS 10.4.x to 10.3.x

I have a Mac PowerPC G5 (1.1) Machine Model Power 11,2
Dual 2.3 GHz Power PC G5 1.5 Gb DDR SDRAM  Version 8S165 it came with Mac 10.4.3 install Disc version 1.0 2Z691-5607-A and 2Z691-5721-A Mac OS X because of some legacy mac software I would like to install the older Mac OS 10.3.x (step up grade 10.3.2 - 10.3.9) it's seem really hard to find that information out. Other than just go ahead and try it? I did find some info Apple website http://support.apple.com/kb/HT1633
from web site:

I believe you can do this in compatibility mode. I know this is not exactly what your looking for, but it has some notes you can apply to your problem.

There should be NO need to downgrade OSX 10.4 to 10.3.
What reason do you have to downgrade?
The newer version of OSX should be fine on a G5 processor.

You probably can't downgrade. Typically, Macs will not boot with system software older than the software they shipped with.

What software is presenting the problem? If you give us specifics, perhaps we can help.

Is the problem that you are trying to run OS 9 software and don't have Classic installed? If so, see: http://reviews.cnet.com/8301-13727_7-10331436-263.html

You can ignore the post about compatibility mode. Compatibiitiy mode is to run old PPC software on newer Intel Macs. Since your Mac is a PPC Mac you don't need compatibility mode.
