anyone know if there is a nice table of Chevy EPROM's BCC codes? If I'm saying that right... Here's the situation...

I have 3 ECM's I got from a relative to try with my 89 chevy p/u. Took out the EPROM's from each, and want to know what each is for... I see they have what I think is called a BCC code... example being one says "Delco" "AWLD" and "7714" going down the chip. Another one says "Delco" then "AKSF" and then the numbers are covered up. I'd like to find out exactly what these two chips are programmed for... seems like I could find out with those codes... but cant find anything on the net for these two chips. Have found others, but nothing on mine yet. Maybe I just need to look harder. Anyone know of a nice table or code list I could use? And also... what does the "AWLD" and "AKSF" mean on my chips? Im assuming each letter corresponds to something...
