Goodies
 Comparison between fx-1000f and fx-5000f
 Both machines do not have the same shape. The 1000f, is lightly inclined, like the fx-10f or the CM-100. The 5000f is flat, like the fx-50f or the fx-4000p for example.
 Functionally, they are almost identical : formulas, ram, functions but the 5000f has the hyperbolic and inverse hyperbolic functions. A small part of the keyboard has been modified :See model : fx-5000f
