Dave,

Good catch and it got me excited for a second there, but I just noticed that I have a typo on my thread title.

The PIC I have is the 18F4580, there is not such a thing as a PIC4850. I might be dislexic . THe file I posted is the correct one, so is the decription of the PIC on the schematic I posted.

Any other ideas? I am setting the "Fail-safe clock monitor" and "Internal External Switch over" options so the PIC can run from the internal oscillator while I get this external oscillator to work. But I have tried it all, so any fresh input from anyone, will really help.
