Thanks, that's what I asked a post down from your's without realizing you had posted that. I gotta see if anyone sells 83+ bodies now

So I was thinking to myself in algebra 2 today, I'm sure it's possible, and I'm sure with the right tools it couldn't be that hard. Just take all the calculator parts and voila! The teacher wouldn't know the difference. I haven't looked at one in a while so I'm not sure what other bodies are similarly shaped, or if you'd have to make your own, but it'd be a good project and a sweet item on the school black market
83+ body fits perfect. I used it for a certain standardized test....
The thing is you will need to print out the schematic for all the buttons (it's in the 89 manual) if you wanna make it look perfect and use the 83+ buttons. I actually went as far as writing a C program for the 89 that behaves and looks like the 83+ shell
Is the body for an 83+ different than the 83? Because I looked at 83s, 86s, and some others, and none of them were curved.
And how did you write the C program and get it onto the calc?
There's a C compiler/IDE available for the TI calculators (at least the 68k ones like the 89, 92, 92+, V200, etc.). My brother (MSCoder610 on these forums) knows a lot more about that stuff than I do, you could PM him.
And I know I've read about people doing exactly this before (the 89 transferred into a lesser calc's case), so it shouldn't be too difficult. If I'm not mistaken, I believe that the 86 and 83 have the same body shape/size as the 89. The screen size might be just a little different though, especially when comparing the 83 and 89.

Man, those have got to be cheap. When I was selling my 83 (not a plus), market price was like $30 or so. Kinda like how market price for the 89 (not the new style one with the extra ports) is, or was, $100.

I had a student get an 89 before I realized I had to make a rule against them... since she already had one, I simply devised all of my tests such that her calculator was of little use to her. It was one heckuva challenge for me to make such tests, but I won.

Oh sh1t... a teacher? I should've made a disclaimer
The thing is, I just wanna be able to buy it now and use it, because it really is one of the best calculators, and I can already tell this teacher is a horrible one. I asked her a question and she wouldn't answer it. Then the second time I asked her a different question, someone else answered it for me after she stood there smiling for 5 seconds. Wtf is up with teachers these days?
SynthDude2001, I might just give your bro a ring (or type, or whatever slang is for such a case). The problem is I have no knowledge of C, and it'd have to be a quick learn since I'd need to be able to use the calc.
That's stupid you can't use 89's. Without my 89, I'd be a sad man. A sad man manually doing equations.
I have a Ti92, I should try bringing that to my AP test

Damn, you need that much power in hs? I only needed it cause I was lazy when I got to college. It never really helped me all that much if I didn't understand the material to begin with.

Exactly. I know that it won't make me get the material, which is the important part. What it will save me in time though is priceless.
If you need a calculator for Algebra 2...WOW Just get an 89 and a scientific calculator. Hell I got a Ti89 my senior year and even in 2nd year calc 95% of its usage was to play TI-Mario XD I could never beat it! The other 5% was just to check my integrations~
But now being a 2nd year in college I barely even use it. Even last year it wasn't anywhere near useful. That and most teachers design courses so at most you need a scientific calculator (if they even allow that!).
Etierh way I'm glad I had an anal Algebra 2 teacher. My Algebra techer was chill and you could get an A w/o too much effort...but my Alg 2 teacher kicked our asses into gear and while it may not be apparant to you now, later one remembering simple tricks makes a world of a difference..

For the 100th time, I plan to. But I don't plan on shelling out cash for a graphing calculator if I can't have the one I want.

Go to FS/FT and get a whole unit. Swap it into the 89 and sell it to a freshman as an 89.
I have an 89. The interface between an 83 and 89 are totally different. 83 don't have menus. The second you power on and a teacher sees it.. they'll be confused.. then you're gone.
I find it interesting that you guys all use calculators.
At my university I don't think any classes even let you use calculators (on the tests)... The point of the class is to learn the material, not a sequence of keystrokes.

I thought the point of the class was to prepare you for the real world.
It's very rare that any employer will prevent you from using a calculator. Half the challenge of math is using the tools. Ever tried to use a slide rule?
Yes, it's important to know what you're doing before you learn the shortcuts, but it's completely asinine to prohibit you from using calculators in any math course.
what are you trying to do scam people?
you can use an ti 83 but not a 89? there is nothing advance in algebra 2 that requires anything more than a scientific calculator. the ti83 is already way more than enough.
you're just out to cheat. admit it. you're just trying to come up with other things to cover up your real intentions. if you that lazy take the course at a community college over the summer. where the teachers are a whole lot easier.
Don't use a Ti-89 in highschool, you will just spoil yourself - in other words you won't learn anything. Also, at my college generally no math class allows calculators, only classes where math isnt the main subject - and even in those math isnt that intensive. Ti-89 is a great shortcut if you already know the math, otherwise your just cheating yourself.
Also who the hell would go through so much trouble to put the 89 in another casing? You said yourself that:
"It's not so much that I plan to cheat but that I don't want to shell out a lot of money for a graphing calculator now then two years down the road finally be allowed to use the one I want (TI-89) in college."
Wouldnt buying a calculator, gutting it, and placing ur 89 inside be more expensive then just picking up a used 83 and selling your 89?
I guarantee you wont need a Ti-89 in college, if you need to do math you can always use matlab, and during tests either no calculators or just no 89's

Well, I'll take your (and some of the others') word on it. I just don't know how cheap 83s are and dunno if I feel like dishing out the cash. I'm sure that by the time I get to college something newer and nicer will be out anyway, but I dunno. It'd still be a fun project.
If you learn the material in class, you will be able to use the calculator in real life. If you don't learn the material, the chances of effectively using the calculator later on decreases.
That's how the courses prepare you for the real world.
I don't know what college you're going to, but I'm barely allowed to use a calculator at all in many of my engineering courses. The only times I get to use a calculator are exams where we have huge equation sheets and the increased functionality of the ti-89 is useless
When was the last time you took the long way to figure out the square root of a number? Give me the square root of 12745832 without using a calculator.
Yeah that is what I thought. Everyone needs to understand the concepts but in the real world you use whatever tools you have at your disposal.
I've heard of people gutting a ti-83 and replacing all the internals with the ti-89's. The outside keys matched up with the electronic keys and the screens fit the same way. However you will have to remember what all the keys are because the 83's and 89's keys are different.
Well, the classes in my university you can't use calculators, but you really dont need them.
Math itself is simple if you understand what is going on, but it is hard if you don't. An equation can be just as challenging if you need to take the square root of 9 vs the square root of 12745832. One just takes longer. You don't need to have students bogged down in numbers.
In the real world, numbers matter and so does time. If you learn the math in class, it doesn't matter what the numbers are, you have the tools to find your answer and a calculator can help you get there as quickly as possible.
Do your university math classes actually give problems that require breaking down numbers like 12745832? I've never seen problems like that at my university.
