No - any old programmer will do, if the only fuse affected is the setting from internal to external oscillator. But if the chips been configured for an external oscillator then you need an external clock source. However, there are fuses (like SPIEN) that can't be enabled via serial programming once they've been disabled. I'd imagine that some of the lock bits may also prevent serial programming. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/
