Lucky guy a SX64,,,but it depends how much you paid...I was offered one for
$500CAN not too long ago....sure I am crazy...

I would check all chips on the boards and push on all of the socketed
ones...specially the ROMs....

By the way, I have been told that 5000 of these SX64 were made...does that
sound right or can someone confirm this?
