Hello, I hope I am not too late, I am not a subscriver of your youtube channel.
This was my dads last multimer and the only one I had so far that connected to the computer, I tryed to upgrade it some years ago and it failed, I can not do anything with it , was too expensive to pay to fix and I don't known how to fix it. I asked my mum and she can send it for free to you, you can use the front and back covers so that the new onwer can have a really nice one, also working display (I think).
Despite my current multimeter having no computer connection it does the job so I am not looking for a multimeter at the moment, I am saving for an digital oscilloscope and in 2 years I should have access to nice stuff at the university.
I would really like to give these parts some usefullness so I hope I can send them to you, can you send me an email?
