I don’t understand why you suffer so much time? This motherboard today is not worth $5. Do you have problems to buy another standard PC motherboard format Baby-AT with a processor socket even a little newer (for Pentium III) than you have now?

That is also an option; I forgot about that. IMHO the FIC motherboard never was a high quality choice. |

no, just my hakko iron and lots of flux and solder wick after that it takes a lot of time but does the job... |

I am surprised why Agilent chose to put these into their highest end scopes at the time these are not industrial grade board, not even a consumer grade, just garbage... |
