I know on an apple computer although the ROM's are pin for pin compatible with a 2716 there is one small difference: one of the chip enable lines has been inverted. If you read the fine print of a data manual you will find this is an option: the polartity of the chip select lines. So.... maybe your lines are also inverted. But then again it seems if this were true you would have trouble copying the data to the EPROM programmmer.
