Any experienced users of hp calculators in Berlin?

[Rafa]

Hi,

i'm often confronted with the fact that users of hp calculators know their preferred devices inside out: programming, hacks, crafting functions not included originally, and even repair!

i'm not a collector, i want to use my calculator and i would like to do so with some degree of confidence. So far i have been mucking my way about the calculators that i have (35s and 28s) and slowly getting myself familiar with them and when impatience gets the best of me i look online for whatever specific problem i stumbled on. This has been mildly helpful with the 35s but the 28s is quite complex and available help online seem to always assume a certain level of knowledge.

I realised that in previous years universities or students themselves would offer a tutorial course on an hp calculator that is particularly used in a field of study and out of these courses a sort of club would emerge where people dig deep into their hp calculators and working on extensive programs and things like that.

This might be a thing of the past, but i can imagine how helpful to meet with others where you can learn in person and can ask all the novice questions you have.
I am not using my calculators for anything complex, i go to an evening school for adults to get the Abitur, A-Levels, Matura, or whatever you call your last year at school in your countries that opens the door for a university study.

Are there people in Berlin (Germany) who use/used hp calculators and would be willing to share their knowledge over a beer? in particular experience with RPL as in the 28s, 48, and 50g but also general programmable RPN of hp.

cheers!
