[Wanted] Firmware v2.5 for Fluke 8840A/AF
« on: February 15, 2020, 04:46:54 pm »

I am looking for the firmware files corresponding to version 2.5 for Fluke 8840A/AF (already have the files for version 2.3, but looking for the latest).
And I say "files", as I would need not only the contents of U222, but also that of U202 (i.e. main MCU).

U202 in a Fluke 8840A/AF is normally a masked ROM IC, so dumping the ROM contents from it is not something trivial.
However, I am aware there are some 8840A/AF out there with a different IC for U202, one using a piggyback ROM.
If you own such a meter with this latter type of U202 IC, I would much appreciate it if you could provide its ROM contents, alongside with the dump of the U222 IC.

Thank you!
