I have a 270c whose trackball seems to have lost its grip, especially when moved vertically -- often it will just spin & spin without grabbing whatever it is it is supposed to grab. I imagine that it's like a desktop trackball, in that there are little rollers that occasionally get gunked up, as with mice. Maybe I'm wrong; I have the service manual, but there doesn't seem to be anything specific about how to get into & under the trackball itself (as opposed to removing the assembly as a whole).
