I think it's my second-hand (original) HP12C, in fine.
It's given a long way to come to this calculator.
For a scientific or a computer scientist, what to think of a calculator without dedicated index register, indirect arithmetic possibility and so on...
And in addition, on which certain keys are obviously not provided with functions: why so much waste?

However, this calculator is a very attractive machine, full of resources and which sticks to my current professional daily life.

In reality, I have a HP12C Platinum with me for its memory capacity which allows me to keep all my favorite programs at the same time in such a reduced volume and without having to re-enter them. (I just use the trick of GTO 001, GTO 002, GTO 003, GTO 004, etc and R/S before using this one or this other, with a corresponding dedicated GTO xxx on steps 001, 002, 003, 004, and so on.

Even, the HP12C wins hands down on the HP15C because of the built-in DATE functions which it lacks and take a lot of resources to reprogram them.
So, the HP12C Platinum is my current pocket calculator, which has embedded the most part of my favorites on this so tiny volume you know !!
