- Sorry, but even if you desolder the surface mount ARM2, it's so close to the
- other chips on the board that I reckon you can't get a surface mount chip
- socket on where the ARM2 was. Also with an ARM3 board on top of the adaptor
- board, things are getting rather close to the back edge of the keyboard and
- the lid.
