I'm running 10.4 on mine and it's roughly the same specs, 233mhz.

However, I cheated a little. I pulled the drive out of the iMac and put it in an external case connected to my Quicksilver But here's the process anyway…

1. Partition the drive. You need to have one partition (the primary, boot partition) that is less than 8GB in size and you need to make sure the OS9 drivers are installed when partitioning. The rest of the drive can be partitioned any way you want it. APM/HFS+ of course on all partitions

2. Install Tiger (Leopard is a no go on a G3, unless you can figure out how to do it - someone has).

3. Put the drive back in the iMac.

4. Boot.

I did it this way because I kept running into too many problems trying to boot/install from CDs. The Mac booted right up. The key here though is a less than 8GB partition with OS9 drivers.

This little iMac I have has less than 100mb ram and Tiger runs slow but I don't use it for much and it can handle streaming internet radio from iTunes pretty well.
Who the heck has figured out how to put Leopard on a G3?????
 
As others have said, it'll run, but not well.

I've gotten lightbulbfan's install of Leopard to boot on my dosdude1-upgraded 400mhz iMac Bondi, but I have no input support whatsoever. I wonder if he ever got that sorted. I just haven't thought to ask...

I still need to get round to fixing that LOL

sadly life things have gotten in the way

but if you install/solder an ADB port onto your iMac G3s logic board that should at least work :D

(FYI you can use the IOUSB kexts from tiger to get mouse and keyboard working but any other USB device still wont work sadly)

I'll have to try that when I get the gumption to tear my Bondi apart again; probably when I get an mSATA and adapter; and only as an experiment. Funnily enough, my tweaked 250 mhz Wallstreet seems to run faster than the G4 Bondi under Tiger. It's probably the ancient 80gb WD spinner that I have in it...
