     Hello,

     in fact I added support for a donated LiDE 80 first. Having the 
real device to work on is more practical and fun than remote access.
     There is also the fact that G124+ chips datasheet isn't available. 
This means more reverse engineering on one side, and the other side, I 
didn't make my mind on how to handle this since other chips registers 
are known.

Regards,
     Stef
