Only from the barcode label affixed to the back of the card. >ATI said they can't identify the card without the P/N 102 number? The barcode label has this serial number, as well as the model name: "Radeon8500Mac64M" If someone has removed the label, there's no way to tell, since the exact same hardware was used for PCs too. The only difference was in the firmware, flashed for PC or Mac.
