Example:
D600AST1B
AKAA0022BPMW
Y5689460375

Line 1:
D600AST1B
The first letter indictates what kind of processor it is. You can probably guess that its a Duron from the 'D'. The following 3 or 4 numbers are its clock speed. This one is 600MHz. The remaining letters and numbers indicate some other info. I hear that you can determine if the chip is OEM or not by looking at it, but I don't really know.

Line 2:
The 4 digits in the middle indicate when the ship was produced. The '00' indicate the year 2000, the '22' indicates Week 22.

Line 3:
Dunno. You tell me.

Thanks Paul, I'm thinking the 3rd line is for the Fab etc: but AMD seem to be keeping that a secret.
