There are some smart battery specs on the web too - it may be that the interface is standard. We'd love to see the GPL code. If anybody would like to write a driver then we will have the code to give them. mds James Klaas wrote: > > I hope this is the right place to post this. > > I don't know if anyone has e-mailed you all about the SonicBlue ProGear > tablet computer.
