New Casio fx-9860 GIII model

[ijabbott]

Apart from the colour, the only significant difference between the fx-9860GIII and the fx-9750GIII seems to be this:

User's Guide Wrote:The fx-9750GIII “Input/Output” mode setting (page 1-31) has a “Mth/Mix” option that enables the same input operation as when “Math” is selected. The only way “Mth/Mix” differs from “Math” is that it outputs results of calculations including √ or π in decimal format.

The fx-9750GIII also selects this "Mth/Mix" I/O mode when entering examination mode, and doesn't let you change it to the "Math" I/O mode:

User's Guide Wrote:• fx-9750GIII : Entering the Examination Mode by selecting Math for the Input/Output setting of the Setup menu will cause the Input/Output setting to switch to Mth/Mix. Note that Math cannot be selected for the Input/Output setting while in the Examination Mode.

I don't checked the technical data, maybe the two model is same, but the most significant difference is the price, of course. If 9750GIII has upgradable ROM and the RAM/Flash same, the 9750GIII's price is 1/3 - 1/4 on eBay. This is significant, and the language is English (not French, like on Graph 35+E II, which is the cheapest Python model).

Yes, I wonder why it's so much cheaper? It seems they are trying their best to undercut the TI-84 Plus.

The postage and import charges from US do bump up the total price for eBay purchase from Europe though.

Interesting thing is the fx-9750GIII can change the implication multiplication priority (on or off) - page 2- 2 and 2-3.

Hehe -- I can see that leading to some major confusion

Not only do all calculators not interpret it the same way, but now there is room for different interpretations in the same calculator!

But we all know the correct way to do it, right?

Let the fireworks begin...

We all know for sure which one is correct, but that's not to say the same correct applies to all of us.

The manual is a bit ambiguous. The description of the Imp Multi option on page 1-34 does not exclude the fx-9860GIII, so I'm not sure if it supports it or not. (The French manual for the similar GRAPH35+EII does not mention such an option.)

I suspect it is only the fx-9750GIII that has the option to set Imp Multi to Off, since Casio seem to be trying to push it as a TI-84 Plus killer in the US market. (Good luck with that!)

What's up with the absurdly low prices on new fx-9750GIIIs on ebay right now? I ordered one for about $32 this morning.

Yes, that's crazy. Yesterday I got a Casio Graph 35+ E II (the French market version of the fx-9850 GII) in the mail for which I paid 14.80 Euros (9.80 for the calculator and 5 for shipping). From a commercial seller and new in it's original blister... It reminds me very much of the HP 39gII, at least in appearence, keyboard and colour scheme. Unfortunately the display of the Casio lacks the pixel count of the HP.

The fx-9860 GIII does not seem to have made it's way to Europe yet. Maybe it is not intended for the European market at all.

My only "problem" (I would not use this word for this kind of thing...) is that - despite the Python label on it's packaging - my 35+ E II does not come with pre-installed Python. One needs to flash it to the just realeased operating system 330_b2 for that. Which only works from a Windows PC. Which I don't have nor want to have.

Would you happen to know which languages it supports for the menus and messages? The French manual mentions it has language settings for use in menus and messages, but doesn't mention which languages are supported.

The choice is between:

English
Espanol
Deutsch
Francais
Portuguese

Mine came pre-set in French, but I set it to Englisch so the the labels on the keys match the system language.

As I can read in a Hungarian Calculator Group, the Python on TI-83CE and on CASIOs is this one: Circuitpython ???

Thanks for any info.

That's good to know. I'm not sure if I'll bother getting a fx-9860 GIII, fx-9750 GIII or Graph35+EII as I already have the fx-CG50.

[Csaba Tizedes]

Csaba: "...most significant difference is the price"
ijabbott: "...I wonder why it's so much cheaper? It seems they are trying their best to undercut the TI-84 Plus."

Maybe the new TI OS pressurized the CASIO: Python with graphics + data sharing via lists between Python and TI OS.

BTW: TI Removes ASM/C Programming from TI-83 Premium CE

The fx-9750GIII I ordered came in the mail yesterday. It seems like there's barely any difference between this and the fx-9860GIII, the most obvious thing being the color scheme.

In a nutshell, it's basically a slightly smaller fx-9860GII with Python and no backlight, and the better USB linking support of the fx-CG50 (mount as a flash drive, import/export CSV, etc.). There appears to be roughly 4 MB of user-accessible flash memory, which is less than the 16 MB on the fx-CG50.

The keyboard feels nice, and is very responsive - I actually like it more than the keys on my fx-CG50, though I think I still like the fx-9860G Slim keyboard a tiny bit better. It definitely responds better to weak or off-center presses than the Prizm does.

Unlike the fx-CG50, it doesn't currently have the casioplot Python module, so no graphics. I'm not sure if that's coming in the future or not. It's also obviously not a color screen, and the pixel size is in fact a bit smaller than the fx-9860GII and fx-9860G Slim (resolution is still 128x64). I suspect it's about the same as an fx-9750GII, but I don't have one to compare to.

It comes with Casio's excellent Geometry app preinstalled, and you can download Physium and Probability Simulator from the Casio web site. I haven't yet tried older add-ins meant for the fx-9860G/fx-9860GII, so I can't speak to backward compatibility.

I think the fx-9750GIII and the fx-9860GIII are the same, the model number differs only in the location the calculator is sold.

fx-9750GIII (United States and Candad)
fx-9860GIII (everywhere else, lost the backlight)

Same. I bought mine for $30 a week ago.

I was only able to find a couple subtle-to-the-point-of-negligible differences between the two, and in at least one case, the 9750 has a feature that the 9860 lacks (the Math/Mix I/O mode). Presumably this is to comply with very specific exam certification requirements in certain regions.

Has anyone else noticed how damn fast this thing is using python?

I ran some benchmarks on this thing using both the built-in Casio Basic language and Python.

First, I get it to calculate \(\sum_{k=1}^n \sqrt[3]{e^{sin(atan(k))}} \) (a function with no intrinsic value other than it gets the calculator to chew through a bunch of transcendental functions) for various values of \(n\).

Using the built-in \(\sum \) function it gets through this in roughly (because timed with a stopwatch) 25 seconds for \(n=10^3\) or 220 seconds for \(n=10^4\). Using a Casio Basic program it does it in about 16 seconds for \(n=10^3\), 164 seconds for \(n=10^4\) or 1650 seconds for \(n=10^5\). Using a python program it does it in only 2 seconds for \(n=10^3\), 18 seconds for \(n=10^4\) or 184 seconds for \(n=10^5\). That's 10× faster than using Casio Basic, BUT with what appears to be greatly reduced precision.

Another test I do is to get a machine to solve the "N Queens" problem, not just for the first layout it finds but for all layouts. The kind of results I get are

Casio basic: 6×6 board 32 seconds, 7×7 board 139 seconds, 8×8 board 670 seconds
Python: 6×6 board 1 second, 7×7 board 3 seconds, 8×8 board 15 seconds, 9×9 board 76 seconds

Here, manipulating integers instead of floating point numbers, it's over 40× faster.
