Can I ask?
I have seen Xtals in parallel (not to be confused with the afore-mentioned
series R) with high value resistors (typically around 10Meg) before driving
microprocessor clock circuits. Can anyone explain the logic behind this as
I'm a little out of my depth with the reasoning for it.

                                                        Sincerely       John

                Could you give a *brief* rundown on your statement
                "Except as noted for our cards".

                Might have to do with 32Khz only, or hi-speed xtals?
