E-mail Jean-Jacques Boulet of the Amiga Repair Center in France.
He is the best person that can help with BlizzardPPC and CyberstormPPC. If he can't find a solution then nobody can.
DCE could do more but they are idiots. If they were any sort of good company they would give another company the possibilty to change BlizzardPPC to rev2 when they stopped support for the BlizzardPPC. This would then offcourse be the Amiga Repair Center in France because he is very good with Amiga hardware.
