|Type:||Graphical programmable scientific calculator with touch-screen|
|Batteries:||AAA x 4 + CR 2025 x 1 (memory backup)|
Introduced: ca. 2000
When I got this calculator I (being used very much to the CASIO and HP
programmables) couldn't even simply add two numbers without first consulting the
manual. I had to read the manual completely to understand this one; its user
interface is totally different from the one used by CASIO for instance.
Niceties:Let's start with the nice things about this calculator.
Not so niceties:There are quite a number of things I don't like about this calculator. I might be biased towards HEWLETT PACKARD and CASIO a little, but even so. Consider the following:
Conclusion:Nice calculator, functionally more than complete, but the user interface needs some work. As it is now, the user interface gets in the way. Somewhere I once read that someone at HEWLETT PACKARD said, way back in the days of the HP 41, something like (ad lib) "the user interface is the main problem for adding more functionality to calculators". The problem is, of course that that is true. So far I've only found one modern (2001) calculator that makes excellent use of formulae entry combined with a nice interface, the CASIO fx-82TL.
And I'm not alone, Ian Balthazar wrote me the following:The site http://basic.hopto.org has a page (in Spanish) on this calculator, also reflecting on the quality of this calculator's screen. Read it here (link valid 2023-01-28).
Loved your feature on the el9600. If I had read it before I would have purchased the CASIO or Texas Instrument.
Now I am stuck with the SHARP. I will like to add that its programming steps are rather inferior particularly logic ie IF GOTO etc.
Anyway keep up the great work.
