Thank you for your suggestion,

The exact steps for the PowerBook g4 and key combinations:
APPLE KEY + ALT + F + O
this actually works.

But sadly it makes the experience unpleasant.

If it was possible to somehow get a key to the g4 1.5 at 64mb of video it would be better.
In exchange for the cancellation of the previous key.

If possible.

If this is not possible, I understand and thank you anyway.

In this case
I will put them both on sale, if anyone is interested can contact me the PowerBook G4 1.67 at 128mb of video ram already has the key activated, just replace the cd player.

At this time, I cannot devote myself to this for personal reasons.

Thanks.
