I have find online this rescure of similar DMM whit the creation of new rom from old pc bios chip https://xdevs.com/fix/hp3456a/ (https://xdevs.com/fix/hp3456a/) but to do the same on 3468 I need the firmware dump

Have a read through this thread:

  https://www.eevblog.com/forum/testgear/hp-3468a-owners-unite-a-storm-is-coming!/msg687107/#msg687107 (https://www.eevblog.com/forum/testgear/hp-3468a-owners-unite-a-storm-is-coming!/msg687107/#msg687107)

There are a couple of ROM images for the 3468A posted within, plus other info about replacing U502.


EDIT: Fixed mangled url reference.
