No, we didn't blow the code protect bit.
The manufacturer seems to think it is a hardware problem, although I am not too sure, as I have done 12C508As, 16F84As, 16F877, 16F873 with no problems at all.

So that is what you'll read if the CP bit was blown, 0000s huh? that's good to know.

I think I chucked the few out that I had programmed, so I will do a fresh one tomorrow and see what transpires.
