Well, mine arrived yesterday. I'm pleased with it so far.

I'm not thrilled I'm disappointed from this model. I wanted multicharacter variables, local variables, real procedures with params, integral of integral, better functions with strings, builtin constants (not variables) etc. etc.. If I wanted to play, I would buy used gameboy or sony playstation portable...

The main point of calc programming (at least in the TI-community) is to push the hardware as far as it will go and make it as functional as possible. For example, this is an example of a 3-D engine that's currently under development by a member named BenRyves.



As you can see, it clearly pushes the processor way beyond anything it was ever designed to handle. There are also plenty of programs that do everything from symbolic mathematics (on calculators without it built-in) and various things to extend the functionality of the calc. Frankly, I see no reason why we couldn't write those things ourselves if Casio only gives us access to the Assembly (or C).

Good to hear someone had it too.
But I remember you said you ordered it > month ago?
May I ask where did you order? (just cusious)

I ordered mine from buy.com - $113 and got it in less than a week. I've had mine for a few days and I like it. TIs feel like crap after using it.
I hope Casio releases an SDK soon. One thing it needs is a CAS. Also, a way to convert common graphic formats to the 3gp and 3gb formats it supports. CSV input would have been nice if text was allowed (it only takes numbers)

[Qwerty.55]

Ashbad, I hardly think this is the place to compare the size of the Casio and TI communities. There's no need to be insulting, nor to bash BASIC. You seem to have forgotten how good BASIC can be in the hands of a decent programmer. Contra and Portal proved that.

if the prizm has no SDK, then it is a pile of dog crap in my opinion. You casio pretty boys have fun with the math-oriented BASIC though

however, even if it DOES have an SDK, the ti community is always gonna be 50x larger, though then I might consider developing for it anyways with the SDK in C or ASM (hopefully raw assembly)

I fully agree with you. The firmware of Casio calculators is really primitive. It's so naive that I suspect that Casio developers haven't studied information technology as the language and compiler theory are the main subject (chomsky etc.) Otherwise Casio couldn't design so limited calculator. In fact one could create only very simple isolated programs - no libraries could be developed ( casio has no stack, local variables or parameters). That is the main reason that Casio has very limited community because no professional wants to waste his time with this calculator... This calculator is for teenagers that want to play or program simple games written with sdk...

[Qwerty.55]

You don't need any of those features if you have Assembly, which is part of the SDK.

[DrCoyote]

Actually, I cancelled my original order.

I ordered mine from another source and got it in just a few days.

[HabanR]

Following the same logic, I could say, that for you personal computer you don't need any library, os gui, you don't even need any high level programming language e.g. C++, it's really enough to have assembler, over night you may develop you own high precision math libraries and after few months you have quite good library background for programming user algorithm you want do do. But you have spend few weeks programming and you have no money from that. It's better to pay more and buy more suitable tool - real programmable calculator) e.g. HP or TI

[Qwerty.55]

How do you think all modern software was developed? It was by people sitting down and writing in machine code/Assembly. No, it's not easy to do, but it has to be done for every new piece of hardware that comes out. The only reason it isn't done for every new computer is that they all use standard architectures, mostly x86. As for those "real programmable calculators," do you think that hasn't been done for them? Let's take the TI-83+ series, since the TI-Nspire is effectively unprogrammable without an OS hack. The only on-calc languages that you can program in are slow TI-BASIC and Z80 Hex. Since the hardware is designed to RAM clear whenever a bad instruction is fed to it (such as C7), you're stuck with TI-BASIC, unless you use your computer. That makes the most programmable of the TI-calculators as good for programming as the Prizm is expected to be be.

I'll take my chances with the better hardware.

You know, that's a very common misconception. The Ti-Nspire is very programmable. It just uses a very different paradigm than other calculators. I've had mine for a while, and though I'm far from an expert, I have made it do some pretty impressive things with very little effort.

Just a correction. The Ti-Nspire is a very interesting machine.

But for everyday number crunching and ad-hoc programming, I love my Fx-CG10 so far.

[Qwerty.55]

Ignoring the OS hacks used Ndless, which give you access to most of the calc, you're stuck with TI-BASIC. It's a great language for math programs, but it lacks all but the most rudimentary I/O commands. I'm not aware of many people who have been able to do much more than that with the Nspire.

But how quickly can the Prizm plot graphs? And do you see any way of executing Assembly code, which would suggest an SDK?

Wow...didn't take long to a TI fanboy comment. I don't care for the inferior-overpriced pile of crap TI makes. I'm forced to lease one in college (for free, wouldn't have it any other way) because the teachers are too lazy to learn a better calculator. I got the Prizm because it has a better screen and it is easier to study graphed functions in it. On TI's crap everything looks like it was drawn with black Legos. Not too good for learning (it is 2010, put a higher-res color screen in the damned thing).

Have fun with your black-lego like games loser, and keep paying $100+ for 1980s technology(yes, your cpu is that old). I don't care for your 50x larger community, I've seen the crap you all made (with very few notable exceptions). Want to play games? buy a Gameboy, kid.

[DJ Omnimaga]

Ashbad, if you are going to troll other forums, I would appreciate that you did not include "Omnimaga" in your nickname. Omnimaga in no way encourage this and I would not even tolerate this attitude on my site.

TI calcs are not that bad, but they are overpriced for the hardware they offer. I disagree with Thanatos_of_MV that most stuff made for TI is crap, though, plus you cannot bring a Game Boy in school, unlike calculator games between classes. But still remains the fact that the Prizm hardware pwns every TI calc by far.

Anyway I notice that this forum has started to become anti-games lately. What's happening here? Didn't the Casio community used to be both to help people use their calc but also game/utility development?See the File sharing section.

A lot of the TI guys are interested in switching to the Prizm and contributing here in the future, because the calc is so much better, hardware-wise, but some are already noticing the anti-game mentality that is reigning here now, and the result is that their Casio contributions ended up remaining on two TI forums.

Didn't notice the very nice 3D engine I posted above? That's running on the "80's" hardware (which actually stems from a 70's era processor and simultaneous SoC manufacturing processes) which you seem to dislike for some odd reason.

And if games are only for game systems, then shouldn't calculations only be for computers? I don't know about you, but I use my computer for quantum mechanical simulations from time to time. Good luck getting ANY handheld calculator to do that. Better just throw away that Prizm with *only* 65,536 colors possible. Heck, even a cheap LCD screen can display hundreds of thousands of colors minimum and still has the much faster computer processor attached.

Hello guys, I have a story to tell.

I opened my fx-CG 10's back lid for replacing batteries yesterday and found heavy leakage ( I did just replace them last month and left the Prizm unused since then), I must screwed out the back of the case out of the mainboard and rinsed in water. I think the Prizm goes not so well with alkaline batteries (I already set a correct battery type) so I suggest anyone using the Prizm use Ni-MH type, it's more expensive but rechargeable and more reliable, BTW I'm not sure if the cause of leakage is the low quality of batteries I used (they're GP Ultra, a Chinese battery ).

Here's a nice video from CES 2011:

[Qwerty.55]

sqrt(50/49) returns (5sqrt(2))/7. X=sqrt(50/49) returns 0 because it's an inequality.

As for the maximum displayable screen size, in Assembly it's 216x384 pixels large. In BASIC, it's somewhat less because of the top of the screen has a display bar, which is approximately 25 pixels high.

[Qwerty.55]

Thank you. I guess I wasn't clear on what I needed. Would it be imposing on you too much to request another reply, this time expressing screen dimensions in your choice of mm, cm or fractions of an inch, please? My eyesight isn't what it used to be. Density of resolution isn't my primary concern. My primary concern is how big (or small) the display area is in length measurements.

And I suppose for non-active border areas, perhaps let's stick with the keyboard-only display results and ignore the programable addressability. Maybe it might be best to pull up one of the enclosed photographs that fills the screen and measure that? Or type in an inequality graph (and execute it) that shades a large are of the screen, easily showing where non-usable border areas are. Or anything else that is easy for you to do.

Thanks for your insight!

Prizm OS 1.02 is available for download at https://edu.casio.co...ad/category.php
More information at http://www.omnimaga....hp?topic=6428.0

[noname11]

WARNING: OS 1.02 from edu.casio.com reintroduces the known locate bug!
In case your device came with OS 1.02 preinstalled: Do not update as this version is DIFFERENT!

[DJ Omnimaga]

For some reasons, I believe that when they made that installer they accidentally put in OS 1.01 instead of 1.02 or they actually made an update to 1.01 without knowing there was already 1.02 on some calcs, and simply did not fix the locate bug again in that copy. I hope they fix that...

[Vinx]

Has anybody thought of fx-CG10 => fx-CG20 conversion using ROM backup/restore process yet?

[Vinx]

Be patient. Simon and the TI guys are already working on it.

Yes, I refered to Simon's work but I don't know any thing of how TI guys concerning this.

[DJ Omnimaga]

Nah, he just means he is mostly a TI programmer who is interested by the Prizm. In fact a bunch of TI calculator owners are examinating the Prizm OS and files to figure out ways to jailbreak it.

[JosJuice]

TI guys means that you work for TI??

No. It means that we're from a calc community that's mostly focused on TI calcs.

EDIT: DJ stop ninjaing me D:

Please forgive my lack of understanding. What does jailbreak mean? Thanks.

It means to "hack" a device to make it run our code. Actually, DJ isn't using the term "jailbreak" 100% correctly in his post, and I'm not sure that I'm using it correctly either.
