Most common calculators in the forum?

[EdS2]

Indeed the HPs are working. The one Sinclair Scientific too, which is the most interesting I think. And all the Sharps and Casios are working. And the abacus and two of the slide rules. And two of the three Psions, and most of the trivial calculators.

I have a frisson every time I see a calculator keyboard, but a slightly bigger one if it's an HP. I think it's a fetish, or an imprinting. It's harmless enough.
