Wanted: Hameg HM8122 frequency counter EPROM image.
« on: April 01, 2021, 12:14:20 pm »
Hello,

I am restoring a HM8122 with massive overvoltage damage. A complete and utter trainwreck, nearly every chip is dead or damaged.
Does anyone have an HM8122 frequency counter and would be kind enough to read the EPROM for me?
It's socketed by default, so it just requires removing a few screws to open it up and pluck it from the PCB.
V4.1 would be great, but I guess any version will do.

Your help is appreciated!

Here you go. As you can see, it is a rev. 4.1 firmware:

The whole firmware fits in only 8 kB memory - amazing.

Good luck with your repair.

Regards

Is V4.1 the latest ever used by Hameg?
