i have the black keyboard on my Ti 8320. no call buttons though... i dont think the 8330's top row is compatible since it's integrated into the whole keyboard "bubble circuit" under the layout tray... the ribbon cable doesnt match up to the mainboard, if i remember correctly.
i have never physically tried... i just had both devices open at different times and remember the 8330 "not looking right".
my av was not safe for preschoolers.
Well, there's no ribbon cable on the keyboard. The small metal contacts are basically taped to the circuit board for the keyboard and there is a plastic keypad holder (that the rubber keypad sits on) that has the top row of buttons attached to it.
