Actually, it's more not possible because the daVinci's keyboard does not
implement the Newton protocol. The Newton keyboard uses a full serial
connection and a documented (well, reverse-engineered) protocol, while it
looks like the daVinci keyboard requires an external clock to drive it.
Interfacing such a keyboard would require some custom hardware, and also
knowledge of what clock signal the daVinci provides over that pin.
