Re: HP-8753E Which PROM Holds S/N & OPT Info?
|
Hi Marcus:?
Ok I am reading 08753-90374, which did not refer back to Chapter 3 (If it did, I missed it). I now see what I need to back up, to include CAL Data in Chapter 3. I will get on this today. The EEPROM which the data I need resides is a Xicor X28HC64J-70, as described by a previous poster. I have a programmer which will read XC28C64, which I think is compatible. The question I have is, will this chip work in a PLCC to DIP32 converter? Dimensions appear the same but this EEPROM has legs to solder. I may have to buy another adapter.
Time to put these 3.5" Floppies from the 1990's to good use!
Rich? ??

Rich, you are not reading chapter 14 thorough enough, see page 14-3 bullet 4 which refers to chapter 3. See Table 3-1. I'm looking in 08753-90484 Service Guide Agilent Technologies 8753ET/ES Network Analyzers. And, I agree with your plan that you need to copy the EEPROM since option code entry does not work for you. But doing a EEPROM backup to floppy is an extra insurance. Learn from my mistakes, see /g/HP-Agilent-Keysight-equipment/topic/49147578 Br Marcus
