- I don't know about the new PB's (160,180,210,230) but in the older
- models the two buttons were physically wired together so there is *no*
- way to tell them apart from inside the machine.

- At a talk the other week, David Levy (who designed the trackball for
- the Duos) mentioned that the buttons on the PB 210 & 230 are in fact
- electrically separate, but the driver software currently doesn't
- discriminate between them.
