It should work in 10.4. It may take checking the install to make certain all the needed kext files are there to support using the Zip drive. But as a data point, I picked up a random Zip disk from next to my older OS 8.6 Starmax where I usually use them and tried it in the Zip 100 drive in my G4 running OS 10.4.11. It loaded right up and mounted the disk to the desktop, and I had not used the drive in at least a couple years. The system disk for the G4 was a clean install from the 10.4 DVD and then used Migration Assistant to bring in parts of my setup from a borked prior system disk.
