When I have a question, it's more easy to have the answer from You in USA (9 hours with airplane), than from my dealer many thanks

Regarding the HD, 9 Gb hard drive is difficult to find... you have any suggestion?

Regarding the battery
See my previous post http://www.synthzone.com/ubbs/Forum10/HTML/000314.html
so it's probably battery problem... is it soldered or just pluged?
