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).

Well, mine arrived yesterday. I'm pleased with it so far.
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.Good to hear someone had it too.

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)

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...if the prizm has no SDK, then it is a pile of dog crap in my opinion.

Actually, I cancelled my original order.
I ordered mine from another source and got it in just a few days.

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

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.
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.

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.

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.

Would you please run this through your CG10 and tell us what it produces as output?
sqrt(50/49)
That's 1 radical enclosing the fraction 50 over 49.
Then please run it again as
x = sqrt(50/49)
(same thing: x on the left, then on the right 1 radical enclosing the fraction 50 over 49)
Where is the 5 in the answers? In the numerator portion of the fraction? As a whole number multiplied by the fraction?
Secondary question: What's the displayable physical screen size, horizontally and vertically, please? By "displayable" I mean that portion which can actually change. I.e., eliminate any borders which do not display any information.
Thanks!

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.

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!

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...
Well, the new version *is* v1.02. The problem is that it's not the same v1.02 that comes pre-loaded on the calcs. If I had the installer for the functional OS, then I could probably fix whatever it is. Until another update comes out though and we can compare the changes, we'll just have to continue with the rather painful extraction of code from the single update available. It'd also help to have some way of identifying where the OS begins in memory.

Has anybody thought of fx-CG10 => fx-CG20 conversion using ROM backup/restore process yet?
Do you have a suggestion on how to extract the ROM from an fx-CG10 or 20?

Sorry for the confusing names, though. Qwerty.55 == Fishbot. This site just doesn't like my browser when I'm logged in.
Anyway, having the OS is different from having a physical memory dump, though. The addresses are easier to understand in a physical dump than in the OS file. That's not to say that there aren't plenty of things to be learned from the OS, like the apparent support for an SD card and NOR ROM flashing.

If you need to abbreviate the term "CASIO" for whatever reason, then use "FX". This looks way better along with "TI" and "HP".

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

Posted 17 February 2011 - 08:15 PM
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.Please forgive my lack of understanding. What does jailbreak mean? Thanks.
