I just pulled this Apple (Matsushita) LF-D211A DVD-RAM drive from a Powermac Dual G4-500. I used the drive to install 10.4 from DVD and played a DVD with it. It seems to work fine in that respect. But I don't have any DVD-RAM media (I don't even know if this stuff is made any more) so I don't know if the writing function of this drive works.
$28 shipped.
I have heatware under BigBadBiologist.
