The latest Mac OS X version for the iMac G4 is Mac OS X 10.4.11 (Tiger)

Unless of course it can run Leopard 10.5
Leopard system requirements:

The iMac G4 has got a PowerPC G4 700 MHz processor, and Mac OS X Leopard requires a 867 MHz processor, so it can't run Leopard

The highest OS X that you can run on that iMac is Leopard 10.5.8.
See the "Maximum MacOS X" near the bottom of > iMac G4/1.25 20-Inch "FP" (USB 2.0) Specs (iMac USB 2.0, M9290LL/A, PowerMac6,3, N/A, N/A) @ EveryMac.com
In order to upgrade to Leopard you will need to find a black Retail Leopard Upgrade DVD somewhere like Amazon or E-Bay because Apple no longer sells it.
Sadly it will probable cost as much or more than your iMac is worth.iMac, Mac Mini, iPad, iPods, Mac OS X (10.6.8), (10.8.2), Safari, iTunes, iPhoto

mende1 is correct about the slowest Mac of that form factor, however, the PowerMac 6,3 iMac G4 does have a 1.25 Ghz CPU, thus it does support 10.5. Sadly updating to 10.5 will get rid of Mac OS 9 Classic compatibility. So consider your options here:
Web browsing under 10.4 is not as compatible as 10.5, but is manageable. 10.5 supports more iOS devices. Though neither supports iCloud.

a brody: Some comments on your article: Classic, Rosetta, and 32/64 bit revisited
At the end of Paragraph 3, it ends abruptly with the words: "For more on..."
I believe that you give too short shrift to the concept of running Snow Leopard with Rosetta in virtualization as an alternative to those who:
1. Have PowerPC apps that they are unable, or unwilling to upgrade or find alternatives; and
2. Have a Mac that requires Lion or Mt. Lion to boot.
Your only suggestion is for them to find a used Mac with original install discs. This is just not a reasonable alternative for most people, and in effect, you are telling them: Tough Luck!
I do not know why you consider running virtualized Snow Leopard as something you would not depend on. If there is no other choice, why not depend on it. At a minimum it buys the user some valueably needed time to continue to run their PowerPC apps until some other option comes forward.
As the principal proponent of virtualizing Snow Leopard, my thread, Installing Snow Leopard (with Rosetta) into Parallel has many positive comments from satisfied users of this approach; most of which are very grateful for some alternative to the bleak alternatives available to them.
The point of your well written piece is to provide all of the alternatives; you should not leave out one of the most important ones for this limited number of users.
Thank you for your consideration.

The reason why is I tried it on VirtualBox with no success. And this version was supposed to work. Secondly there is much question whether or not the licensing allows Snow Leopard client to be used in virtualization. I do refer to your process both on my Snow Leopard tip & Kappy and my PowerPC migration tip. I'll be editing the Classic, Rosetta, and 32/64 bit once I can with full editing capability. For whatever reason now, the Full Editor does not work on it, so I can't upload the images. It was enough to correct the old knowledgebase article links.

OS X 10.5 Leopard will run on this iMac.
I used a G4 MDD with a 1.25 Ghz CPU and 10.5 ran just fine.
I would make sure that this iMac had the max. RAM of 2 GBs installed for good performance.
1 GB of RAM really won't cut it.

Use of this link squelched all of Kappy's fears on the subject:
I cannot seem to locate your User Tip Contribution on Snow Leopard, but thank you!

https://discussions.apple.com/docs/DOC-2455 is my Snow Leopard tip. It is on the Snow Leopard forum.

Ah, thank you again! I was looking in the User Tip Contributions under your name.

The scrollbar should fix that. I know that's a bit of an issue with some ASC posts.
