Hi, all! I have a G3 Pismo Powerbook that I use to play classic mac games. About a year ago, the DVD drive stopped reading discs. I thought that the drive itself went bad. So a week ago I finally got around to buying a new DVD-ROM drive. (Model M7931) I plugged the drive in and..........nothing. I am wondering if some other hardware component could have failed. Or could I be looking at a software problem such as an extension issue? The OS is 9.0.2. I would greatly appreciate any insight! Thanks!
