Hum, the HP10s+... that one is funny, because it happens to be a Casio. A cheaply made derivative of the FX-MS series (just shuffling a few keys), with (even) worse keys and worse stability. The thing likes to drift when keying and also rattles if you've slid it into the cover to do so (put some cardboard between, thank me later). I know it's a 10€ calc and YGWYPF, yet still...

I had to buy one to get used to it for a test. Some civil servant thought it was about time to standardize and chose the cheapest one. Good looks and the nice touch of a recessed ON key, but Casios (with a Casio label on the faceplate) are usually better engineered and the original FX-MS have much nicer LCDs.

I do know it is a Casio calc because I'm familiar with them and well... if you press four times MODE to get to the Disp menu, and then press "2" (hidden option) it displays CASIO (Kinpo can be like this).

What's that strange-looking key in the lower right corner used for?
