Well see Dave its like this: I have no idea if there is a resonator or not. I am guessing not. I didn't add 1. my entire circuit is the chip, an led, and a wire to Vcc for MCLR. But there are built in things like automatic tie in to pwr and gnd, so MAYBE? and I didn't even put a resistor in series with the LED. So these things make me go Hmmm. But the LED was blinking at what appears 1 sec rate.
