How to read steppings?

[BigPete]

Anyone have a link on how to read the stepping information on my CPU. Here are the steppings:

ADA3500DIK4BI
CBBID D0451APAW
1169135L40805

Thanks.

After a little research, I have come to the following conclusion:

ADA - Desktop CPU
3500 - Processor (3500+ for me)
DIK4BI - Not really sure, I think it stands for the size (.90u), voltage, etc.
CBBID - 4th generation Winchester? CBBFD was the 1st gen?
0451 - Week 51 of 2004
APAW - Factory Code
1169135L40805 - Serial Number

Is the above info correct?
