Hi, Pier4r,

. . .

But then Casio has got newer models like the fx-991 X Classwiz series that, despite limited to what the built-in algorithms can offer, also have continuous memory and a solver.

Casio also offers the current top of the line, scientific, non-graphic, programmable fx-5800P pocket calculator. Not only it is programmable as it offers a solver and formulas as well.

The Casio fx-991X does not have continuous memory in regular COMP mode. When it times out after several minutes of non-use, all of your calculation history is lost; deleted.
