Hi Scott, A typical proccessor crystal will have 20 to 50pF of load capacitance. If there is a capacitor from each uP pin to ground, these are assumed to be in

The crystal package , does it stand up or lay flat with a solder tab on the opp end from the leads? Can you take a pic of the parts around it? Thanks -- Scott

I don t know much about crystals either but looking at specs on Mouser they quote the load capacitance for each of them, so if you can find a matching part it

A&MS should have it in the US. It was in the part stock sent from YCNA to them. The part was also used in the K2600 If not, you can get from other sources.

A screw driver! If you want to avoid creating an arc, then just use a resistor of two hundred ohms or so.
