Oke, we have an insider....
If so, CMMs have changed from "my days".
I think so, the specific FCSC CMM consists of 3 parts with a total of 2000+ pages.
Part A: General CMM (more ACMM with IPL and
general description, diagrams, assembly etc) but only for casing and interconnecting board.
Part B: The Interconnections in detail
Part C: The ATLAS Test specification and it says - for ATEC series 6 -.
This ATLAS code says more to you than to me and the 'public'.
Anyway, for this type of computer, the required test equipment - today! - is the ATEC series 6.
The boards have their own CMM (I agree: for level 3 workshop) and the software logic and data resides in the OBRMs.
So, with this fragmented CMM information it will not help you to understand whats going on - inside -....
