Most common calculators in the forum?

[pier4r]

Updated the first post. I tried to consolidate the models, almost in "series" (I try to look at wikipedia or hpcalc.org to see if the models are mostly similar).

nevertheless if you spot something that does not fit or an error, please let me know. For example I learned some months ago that hp 35 and hp 35S do not have much in common.
Another example is that 49G+ and 50g should be considered in the same family, but the build quality of the 49g+ is reportedly so low that I kept them separated.

So far the expectations works properly. 50g first, 48g third (not second), Prime equal to 50g. We will see with some more posts if we get surprises.
