Just wondering if the new PowerMacs still use the old school ATA 66 IDE bus? I have a Compaq with an ATA 100 card and the same 30 gb Maxtor drive that I have in my G4 400mhz tower. The ATA 100 is definetely alot faster than my Macs 66. I couldn't find this info on Apple's web page under the tech specs. Any ideas??
