Any experienced users of hp calculators in Berlin?

[Hiwi]

Hi Rafa,
i am an experienced user of the HP48 and Hp28S. And I like to share everything. I love the philosophy of repair cafés. I am an active member of the rapair café in our town.

And I am using my HP48 every day private and at work.

I live in Hamburg but I have a very fast motorcycle, so I like joining a meeting at Berlin, if you will get a meeting going. But avoiding the beer :-)

What about a zoom or jitsi meeting?

Ralf

PS. Are you the guy which I have explained the directory structure of the HP28S and the polynom solution with the solver last year? He was from Berlin, I remember.
