HP-48GX key stiffness

[anyfoo]

Thanks everyone, really insightful.

Since RPN was mentioned above: Besides already being an owner of HP Prime (in RPN mode) beforehand, and doing some semi-extensive use of both HP-48GX and HP-50g emulators, I have also been using emacs-calc for years, so I know that RPN is right for me.

As for the key click: It overall sounds like that's just how HP-48GXs are, with mine in particular being of an even more clicky variant perhaps. cdmackay, you say your Indonesian model does not exhibit this, but what are you relating your observation to? As I said, this is the first HP calculator of that era I've ever used, so I don't know what is the expected amount of force.
