I'm using them on a 16c74a. We've probably shipped a thousand units now with absolutely no problem. I did find that the resonators from Integrity Technology and ECS do not seem to work reliably with the PIC (at least the ones with internal capacitors). They may work fine at lower frequencies or with other chips. The muRata is something like a 50 cent part and looks like a 3 lead resistor SIP. Ground the center pin, connect the two other pins to the PIC and you're running! Harold
