GridPad 1910

I recently got a GridPad model 1910, and I have a few questions... Does anyone know of a source for batteries? (Mine doesn't have one) Is there a version of basic specifically for the gridpad, or does anyone know how to get input from the screen with a general PC Basic? Does it require any special type of keyboard? Anyone have any documentation for it, especially for the docking station? connector on the bottom? Anyone have or know of software for it? This thing is pretty rugged, and I'm thinking it would be great to mount in my Land Rover to use for navigation (which means finding a DOS-based nav program that can work with a GPS.)
