Read here to find out about the 40 vs. 80 pin IDE / ATA cables... It is all about shielding apparently so yes they still have 40 wires that transfer data... http://www.storagereview.com/guide2000/ref/hdd/if/ide/confCable80.html So the mac might have already had a 80 wire cable in it? If you are wondering what might be the limit to 16X burns it might be the actual ATA bus in the G4. Which I believe is an ATA 33 controller for most G4's. Again another situation where a faster ATA PCI card would be useful. Daniel J.
