I recently bought a CD Drive from Pioneer for my old 6100/60. The drive was intended for PC's, but I could get it to work by changing some numbers in the Apple CD/DVD driver. I'm pretty satisfied with it except that I can't get the sound to work through my computer. The salesman told me that the sound was sent through the scsi cable on Macs, but I don't think he's right. Do I have to connect the drive to my motherboard with the little cable that came with it? And if I have to, where do I have to plug it?
