Casio FX-750P
I swear these Casio calculators drive me bonkers. No, not all of them, just some: those, in particular, like this FX-750P, that have a separate ENTER key on the numeric keypad and a carriage return key on the alpha keyboard. Two keys that do not have the same function. So every time you enter a BASIC command and hit ENTER, you get an error message. Groan!
Of course if you use this machine every day, it is easy to get used to this, ahem, "feature", and for all I know, it is quite possibly more practical than the silly MODE key that I so detest on other Casios.
The FX-750P is also superior to typical Casio BASIC machines in other ways. It has a more comprehensive set of functions (including, for instance, hyperbolic functions and statistics), and it also has two RAM card slots for additional memory.
The programming model of the FX-750P is demonstrated by the following example, computing the Gamma function to a high-degree of precision using the Lanczos-approximation. Don't forget to use the correct ENTER key when entering program lines... it's soooo annoying, having to enter the same long line twice!
