Re: A Problem with my Softrock Lite II for K3
Unless it is in a SMD package, as the one Tony appears to have supplied.
There are a few different standards, on that one the crystal is in between pins 1 and 3. Pin 2 and 4 are not used.
Not sure how pin 1 is marked, possibly something etched near the corner of the package onthe top.

I expect Bob has found it, a PDF here
It does have a pin 1.
Even that is not too clear, Pin 1 is bottom left when looking at the top
with the part number the right way up. The one nearest the "C" of the part
I seem to remember Tony saying something about this, but I have not found
