HP-8753E Which PROM Holds S/N & OPT Info?

 

All:

I posted earlier in the week on issue pertaining to my inability to enter a license key for my 8753E. While I solved a definite problem in my A9 CPU Board, the PLCC EEPROM does not contain Serial Number or OPT information. After peeling back a few stickers and looking deeper, it appears I have multiple memory devices which would hold this type of data.?

After looking around the CPU Board I have no less than 4 Dallas DS1610's and 2 AMD AM27S191ASC's. I think the Dallas NVRAM probably contains calibration constant for the VNA. I am leaning towards the two AMD27S19's. Can anyone confirm which chip on the A9 Board houses the data I need to gain access too?

Rich??
