how to decipher IBM "JOB" parameter?

[apa4]

So i tried to look up the information online but failed...
Often we can see the "JOB" parameter on IBM's MCM chips. It should hold some reference to information like number of cores or actions per second etc.

Does anyone has a clue how to decipher some information from "JOB" parameter?
For example this one has JOB = 00LBEL

OR maybe someone knows a way to get some information from this type of marking.

I guess I would wonder why your information request would be important.

P/N means part number and that is the important code in determining
what IBM system a part was used in. The 86F3354 TCM was used in an
IBM 9121 ES/9000.

I hope this helps.

Part number Will tell us the machine (hopefully)... Different TCM's were used in 9121 machine... 9121 TCMs have different number of dies inside. I found out that number of dies is related to JOB parameter.
