Downgrade PowerMac G5 from 10.5 to Classic-capable OS?

Just acquired a dual-processor very early PowerMac G5. I was able to install OS X 10.5, but I really need a Classic-capable earlier version of OS X. Where might I find one. I have an "Install DVD for OS 10.1", but that won't load.

PowerMac, Mac OS X (10.5), Dual processor, PCI bus

Purchase a retail Mac OS X 10.3 or 10.4 package and install that onto a blank drive or partition; if needed, Mac OS X 10.5's Disk Utility can repartition the internal drive without erasing it.
