CASIO releases new graphing calculator with 3D function
Casio Computer is launching the new colour screen graphing calculator FX-CG50 that is able to draw 3D graphs. Innovative and easy-to-operate functions as well as the high-quality design make this calculator an advanced device for practical mathematics teaching.
Norderstedt, 18 January 2017. By offering 3D visualisation of results in graphs, the FX-CG50 helps pupils to learn intuitively the relationship between formulas and graphs that calculate spheres and cylinders. The device can display up to three types of 3D graphs overlaid on one screen. Besides, users can visualise the cross section of the sphere.

Advanced tool for mathematics and science teaching
CASIO's new FX-CG50 is not only useful in mathematics, it is also highly suitable for experiments in physics and chemistry lessons. The calculator can simply be connected to the data collection interface C-Lab¹ in order to measure data by means of various sensors such as temperature or distance. In addition, triaxial acceleration can easily be calculated using the FX-CG50. Connected to the C-Lab, which is equipped with Auto ID recognition, the calculator automatically recognises the type of sensor connected. The results of the measurements can be displayed as graphs on the calculator's display.

CASIO offers reliable calculators with attractive design
The product's design is a facelift of the successful model FX-CG20. The body has been coated with a special finish, thereby enhancing the elegant surface and design. In addition, keys in a metal look emanate a sense of quality.

Casio Computer developed the world's first graphing calculator FX-7000G in 1985. It was able to display graphs of various mathematical expressions. In 2010, the colour graphing calculator FX-CG20 was released, equipped with a Picture Plot application. Continuously developing its school and graphing calculators, CASIO is a reliable partner contributing to modern mathematics education.
Judging by the screenshots, and as expected, internally the OS is probably not very different from the one on the fx-CG 10/20.

The screen resolution, memory size, etc. are all the same as on the fx-CG 20, judging by the DynaTech page.

The Main Menu went through a major redesign, but the apps appear to still have the same icon size, 92x64 (but they are carefully crafted so that graphics don't go behind the text, except for the blue background on selected apps). The key shortcut indicator overlays are now drawn slightly lower and to the left. Other than that, and eventually some adjustments to the scrollbar, this redesign seems to have been carefully conceived to avoid updates to the code that draws the Main Menu - all they had to do is replace the images. The icons grid is still drawn at exactly the same coordinates.
From the Main Menu alone, I don't see anything indicating add-in support is gone... (even though I believe it is). TeamFX, care to elaborate?

Here are the Main Menus overlayed:

The fonts appear to be all the same - yes, including the horrible PrintXY font where the only thing that looks nice are numbers and symbols. Apparently they have not messed with the graphic style for the 3-bit and 1-bit graphics.

The backgrounds for built-in apps appear to have been revamped, as far as the C-Lab screenshot seems to indicate.

I actually like the style changes; I have always felt the dark, glossy, metal-inspired theme of the Main Menu on the fx-CG 10/20 provided a too jarring of a transition from the rest of the OS, which is mostly white. The new icons have a flat design instead of a highly-detailed plastic 3D appearance that throws us back to the WinXP days. The new backgrounds (judging by C-Lab...) also have a simpler, flat if you wish, style. Small changes that make the UI look much better IMO.

From the Dynatech page:
Symbolischer Löser (Lösung mit Umformschritten) - ja

CAS? Confused
If confirmed, that explains why there's no exam mode saying on the case... they simply are not targeting that market.
But I think this is either an error, or it doesn't mean what I think it does.

Erweiterbare Funktionalität durch Applikationen - ja

(probably fake add-ins)

I don't see anything here that would require a faster processor - the 3D graphics don't look that demanding (especially since you're apparently limited to a selection of function types - plane, sphere... to their credit, they are rendered in full-color mode!), and we already had Graph3DP on the CG 10/20 proving it was possible... - so I think they are still using the SH7305 at 58 MHz
From the Main Menu alone, I don't see anything indicating add-in support is gone...

Old add-ins will break their refurbished main menu design. They could, however, provide new icons for official add-ins in the OS and they could also provide a default icon for unofficial or semi-official add-ins, but I doubt they will bother themselves with that.

I actually like the style changes

It's basically the fx-CP400 main menu design:

Symbolischer Löser (Lösung mit Umformschritten) - ja

Same text on the fx-CG20 page. Perhaps an error.

Well, of course - I think everyone agrees that style inconsistencies would be the least of our problems. Even if this new calc has support for actual add-ins, i.e. native code that runs from files in the storage memory, I highly doubt anything will run as-is. (but yeah, if they cared about 3rd party development and/or the ability for people to transfer files with previous models, including official add-ins, they would make it so... the Prizm has a MMU, and add-ins use virtual memory and syscalls, so all the pieces are in place for the perfect compatibility with previous generations, even if a layer is needed. But just like with your default icon ideas... they don't bother)

It's basically the fx-CP400 main menu design:

Actually, it's an evolution of that design. The fx-CP400 menu icons still have some glass/glossy effect on them, and the menu scrolls in a different way. The icons are also different.

Same text on the fx-CG20 page. Perhaps an error.

Well, I ported Eigenmath to the CG 20, so in a way, it's not an error... Rolling Eyes
I believe many of the Dynatech specs are incorrect by simply being copied from fxcg20 like weight, dimensions, batteries but I agree with gbl08ma's observation regarding screen and icons resolution and possible addin support even so I don't think we can rely on Dynatech reference to expandable functionality...

Question please: Does clab or ea-200 indicate 3-pin cable support or are they connected via usb given mentioning of auto id... I disregard Dynatech specs about calc to calc cable because I think they have not updated them properly
I think we are just going to have to wait and see what more information Casio will release. I agree that many specs are unknown and I am sure the calculator has different dimensions and weight.

Additional calculator applications/add-ins

Yeah, yeah... it's brainstorming time.

These are all the official add-ins for the fx-CG 10/20:
Conv.g3a - 29180 bytes [doesn't count]
Geometry.g3a - 764720 bytes
Physium.g3a - 1813180 bytes [largely because of the many full-color images]
PictPlot.g3a - 83636 bytes
ProbSim.g3a - 404573 bytes [largely because of the many animations]

The total size, not counting the conversion add-in (which if done away with, wouldn't even need a main menu icon), is about 3 MB. This includes headers, which are mostly icons, and these need to go somewhere if the app is to be shown on the Main Menu.

On the fx-CG 10/20, which has a 32 MB flash chip, roughly 16 MB are used for the storage memory. One sector, 128 KB, is used for the bootloader. Three sectors (384 KB) are used for Main Memory backups. One sector (128 KB) is used for owner information (Utilities can show you the info contained in this sector). One sector (128 KB) is used to store the currently selected add-in language, if any (they could have used the MMU and map the g3l dynamically, but they apparently didn't). I believe at least the stack and heap for the currently running app are also copied to the flash. This leaves us with about 14 MB left for the OS. That includes code (obviously), built-in graphics and languages. But at least in older OS versions, not all of that appeared to be used - I'm not sure how things are now after vector calc, the exam mode, etc. were implemented, but IIRC in earlier versions they left a nice buffer of about 1 MB unused for future expansions. TeamFX can probably give us better numbers, it's been a while and the docs I have aren't helping.

Moving on to fx-CG 50 theories...

Since the storage memory is apparently still 16 MB on the fx-CG 50, let's assume they are still using a 32 MB flash (the next logical size would be 64 MB; I'm pretty sure the OS doesn't take 48 MB and it would be very mean of them to artificially limit the storage memory by over half of the possible capacity - oh wait, fx-CG 20 AU...).

So, where did they put 3 MB of add-ins + the new 3D graphs code + the new E-CON4 code?
Did they finally decide to compress graphics, or did they cut down on them (Physium for example is still useful without KB and KB of stock images...)?
(Do they still have two identical copies of the shutdown logo?)
Are they still wasting a whole sector to owner info?
Are they still wasting a whole sector to language add-ins - wait, are language add-ins still supported? (perhaps my previous subtle allusion to the problems of null-terminated strings gave them ideas?)
Or most interestingly... maybe the answer is to optionally put some of that code in storage memory, and we have a name for that... real add-ins? I guess we'll find out soon Smile
The reserved OS code/data size is 0xB60000.

0xB60000..0xB80000 is reserved for add-in languages.
0xB80000..0xBE0000 is reserved for MCS backups.
0xBE0000..0xC00000 is reserved for user name and organization.
0xC00000..0x2000000 is reserved for user data.

Don't ask me why the actual user area is 20 MB in size.

In OS 2.01 and later, all OS code/data must end before address 0xB20000 as this is where some exam mode information will be stored.
Actual OS 2.02 data ends roughly at address 0x70F9A0. So this gives about 4 MB of free space left.
That is more that I thought. If on the fx-CG 20 there were 4 MB left then for the fx-CG 50 I can see Casio putting there all the code and assets that were previously stored in g3as, plus the new 3D graphing code and other OS enhancements. And they can probably reduce the user area from 20 MB to just over 16 MB...
Furthermore, a bit of effort in size optimization can go a long way (from eliminating dead code, to eliminating duplicate assets, and finally compressing them... there's probably an easy 1 MB to be made there).

The only good news to come out of this, is that with add-ins gone, 3 MB of the storage memory would now be free for data... in Casio's formats only, as there would be no chance for e.g. a third-party image viewer.

I should probably take some hours to put myself in "Casio mode" again to finally collect all the bits of memory maps, both of flash and RAM, that have been made throughout the years, and put them together in one place, in the Prizm wiki.
Comparing vs shows no deletions and only the following additions for fx-cg50:

• 3D-Graph
• E-CON4
• Catalogue Function
o 3D graphics: preinstalled / Add-In
o Catalogue function

so my conclusion still is that those new details were released without being properly updated by Casio.

On one hand I fully expect FX-CG series to maintain existing addin functionality (I even wonder if 3D graphing will be an add-in in itself hopefully even loadable on FX-CG20) so that OS can be shared between FX-CG10/20 and 50...

I still doubt very much dimensions would have stayed exactly the same for the newer model and I think AAA batteries would have been gone to make the new model more compact too. So I think we need to wait longer still to have more details
French model: Graph 90+ E

Cute but yellow/orange letters above keys may be difficult to read on white background
Please Casio, new official SDK and addin support.

A calculator that can't run compiled code, is not good at all.

If they make it third party addin compatible, this will be a very nice development platform
one of links for the French model has the following
Weight: 272 g
Dimensions: 17 x 185 x 87 mm

I still think it is too big and heavy.
Making the 3D graph part an add-in, fake or not, would have the advantage of making it easy to disable to comply with any exam regulations where 3D graphing abilities are disallowed, but document visualization is allowed (making the exam mode too restrictive as it blocks access to files). Like with the Conversion add-in on the fx-CG 10/20.

Speaking of complicated version names... of course they had to change the model name for the French version, as is tradition. They sure know how to add to the confusion...

I think there's an extremely low chance that the OS can be shared between the fx-CG 50 and the 10/20. At very very most, it can be ported to the older models, and that's assuming it doesn't require twice the RAM.
Similarly, while the new catalog and E-CON4 may come to the 10/20 one day, I highly doubt 3D graphing will make its way there. Besides being a major selling point of the new model, it may require a much faster CPU and possibly more RAM.
The Graph 90+E's price tag is very high, especially for an almost certainly closed platform...
Vote with your wallet, if after a year or two the sales numbers don't match Casio's expectations, they'll either scrap the model or lower its price...
I imagine the French market is quite important for them, for it to make sense to manufacture different cases and marketing materials for the Graph 90+E instead of simply using the "worldwide" models.

Note that they seem to have given up on the idea of having a separate model for the American market, as there's no fx-CG 10 counterpart to the CG 50 (unless it's yet to be announced, or perhaps they won't launch it in the USA at all...).
I think the first announcement was for US with $99 recommended price

Btw, Casio has discontinued the fx-FD10 Pro which was launched in 2014:
This model was very expensive...
