Welcome To
Discussions Bob!
With supplemental
RAM added to the original
256 MBs, the
1.0 GHz iMac G4 80 GB will support
Panther, Tiger, or Leopard.
And below, I have customized for your situation, the post
Dale Weisshaar referred to.
If you call
Apple Phone Sales
1-800-692-7753, you can order
Tiger 10.4.x, for
$129.00.
If your
Mac meets the
Leopard System Requirements, the
Full Retail Version, of the
Leopard Install DVD, can be purchased at
The Apple Store (U.S.).
Panther, is no longer available directly from the
Apple Online Store, as
Leopard 10.5.x, is the most up to date OS.
If you know what to look for, a
Full Retail Version, of the
Panther Install CDs, a
Full Retail Version, of the
Tiger Install DVD, or a
Full Retail Version, of the
Leopard DVD, can also be purchased,
sometimes less expensively, at some online
Apple retailers, Amazon, eBay,
FastMac,
HardCore Mac,
AllMac, etc.
This is the correct one
OS, Mac OS X 10.4 Tiger, (DVD) Retail $149.95, at
AllMac.
This one
Mac OS X 10.4.6 Tiger, (DVD) Retail $159.95, at
FastMac.
And this one
Mac OS X 10.14 Tiger Retail $199.99 at
HardCore Mac.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Panther is only on CDs, not DVDs.
Tiger and
Leopard are on
DVD.
The discs should look
exactly like the images in the above links, and not say
Upgrade,
CPU Drop-in DVD, or
"This software is part of a hardware bundle purchase - not to be sold seperately." on them.

Caveat Emptor!
If any are presently available, examine these items very carefully, and if in doubt, ask questions of the seller before purchase!

Once
Panther 10.3.x is installed, you can use the
10.3.9 Combo Update, to upgrade to the final version.
If your
Mac meets the
Tiger System Requirements, you could also consider installing that, and then use the
PPC 10.4.11 Combo Update, to upgrade to the current version.
If
Leopard 10.5.x is installed, use the
Mac OS X 10.5.2 Combo Update.
Review these
KB Articles, for the
Panther System Requirements, and the
Additional Panther System Requirements.
The posted
RAM System Requirement, for all versions of
OS X, is the
bare minimum.
For optimum performance, more is recommended, and as I previously noted, additional
RAM is absolutely required for
Leopard 10.5.x.
Shop Carefully, Examine All Documentation, And I Wish You Success!
