Bugger! > >Neil How do you know what the controller chip will do? Do you have specs on it? Difficult to add another 16 data pins and keep the same number (68) of total pins. So what do you think they got rid of? Some address pins? power supply? Ground?:) I wouldn't be surprized if cardbuss isn't already software doubling the pins to get what they need already. Remember they do need to keep backwards compatibilty plus hardware is expensive.
