Hi everyone,
I am posting this here in hopes that someone out there can help me with a MAJOR mistake!
I erased the EEPROM to my HP70900B Local Oscillator, this in turns kills using the Spectrum analyzer,
and other instruments in the system.
So, if there is anyone out there with a HP 70900B that is willing to read their EEPROM,
or if you had a spare ROM board, I would love your help.
My firmware version is 900314 and if your unit has a serial number between:
3022A00558 to 3033A00707. Reading the EEPROMs is all that’s needed.
Serial numbers before this can be used, but your unit must be a B unit.
Serial numbers after mine can only be used, if you are able to send the whole ROM/RAM board.
Serial Numbers 3414A01968 and above will only work, if the controller board is 7090-60143.
I know this is a lot to ask of someone, but know that you will be helping a poor student and disabled vet.
Thank you all for your attention.
