Casio FX-602P

[isanchez]

HI,

like always...you were right: it works fine with fresh batteries. The thing is that there is no low battery indicator. As soon as I have replaced them, it worked fine: no error messages and the printing is fine.
I find these two calculator families FX50x & FX60x were probably the best produced by Casio ever. They were designed to compete with Hp41 series. The best argument probably was the low price, and you get alphamumeric (60x), programmable, calculator with priting and storing capabilities. I think they are nowadays the most expensive and wanted Casio calculators from the 80's.

Thanks and kind regards

Ignacio
