PowerBook G4 Titanium Onyx PRAM card location?

Is there a guide to change the PRAM battery card? There is a guide once you've found the card it's soldered to, but not where to find the card.

I don't see this card within any other repair guide as a step, either.

Is this a good question?

In either the older Onyx or newer DVI models the PRAM battery is located under the optical drive.

Here's the Onyx IFIXIT guide to remove the DVD drive PowerBook G4 Titanium Onyx DVD Drive Replacement. You can see the PRAM board here:

It's the same board and the battery is soldered onto it so you do need replace the board unless you can get the battery with tails. Here's the IFIXIT part: G4 Titanium Onyx or DVI PRAM Battery
