Any experienced users of hp calculators in Berlin?

Here is another book by Wickes "HP 41/HP 48 Transitions" which is obviously specific to an experienced 4 user, but for the basics, 41 is just one of many RPN machines. For the initial learning curve this may be best, but after basics, it moves into more 41-specific behavior, which is why I suggested the other book first.

When I do come to Berlin, I will indeed look you up for a few famous German Beers. Which I like.

I have an "HP friend" that lives in/near Berlin, I will contact him and try to put him in touch with you.

Enjoy the new toys!
