TI-84 Plus Released
clear issue writes "The TI-84 Plus has now been shipped, and is avalible through a few distributors. (Try froogle) Besides the new stylish interface, when compared to the 83+, the 84+ has a number of technical advancements including a 2.5 times faster processor speed. To see how this new device compares to your current calculator, check out ti's comparison pdf chart. TI has even dedicated an entire web site for the promotion of the 84 Plus."
I emailed "daddypants" while it was still in the Mysterious Future, but to no avail.
Not at all. The different calculators are aimed at different groups and for different purposes.
The 92/+/v200 are aimed at engineers and other professions/things to do while the 83/+/84/+ are aimed at highschool students (mainly).
The TI-92 isn't allowed on SATs and some other tests because of the QWERTY keyboard. This one probably would be allowed by standardized tests and by teachers in school, so it's good that they're working to improve the TI-8x type calcs.
TI's models are designed to suit different needs, the TI-82, TI-83, and now TI-84 are aimed mainly at High School level maths, though the 83 is generally considered the best calculator TI makes for doing statistics work. The TI-84 is just a revamp over the TI-83, just like the TI-83 was to the TI-82 before it.
When TI finally releases a better calculator, I hope they also release an upgrade for the 89. After all, the hardware will be sufficient for a long time. With 700k+ memory and a good-sized processor (I think it's 33Mhz underclocked to 11Mhz), it should work very well for just about everything but non-linear differential equations and other extremely CPU-intensive operations.
When the time comes, all we will need is a firmware upgrade to keep it around for even longer without having to upgrade. I've used this calculator for 6 years now, and I recommend it to everyone looking for a high-performance calculator. I hope to try the new HP calculator so I can compare to the competition, but I just don't think I can set my 89 down after all this time. I know it all too well.
the "myth" has no place here. It is the exact same processor architecture except it clocks 2.5 times faster. Calculators are much more simple than your average PC (no multitasking (natively, at least) and not many things it can do). and just as a random fact that serves nearly no purpose, it's a z80 processor

Although it looks funny.
Being called a dork on Slashdot must be like being called the retard in special ed.
the 9x series has just been renamed to the "vxxx" series. Google for Voyage 200... it's their newest qwerty calculator.
Perhaps because I saw the GBA article above this one on the main page, I remembered a page I had seen a while back about overclocking your TI(change in capacitor). Thought it was pretty cool, I'd try it but my calculator is school-owned. Somehow I don't think they'd find it as cool as I would. =)
Uh, no.
You're correct in that the TI-89 Titanium has the same processor as the original TI-89, but the new TI-89's processor runs at 12 MHz, as opposed to the original 10 Mhz.
Granted, it's not a huge difference (20%), but it would be noticeable.
And as to your assertion about the 49g+, I haven't personally used it, but I've read a lot of reviews -- and it seems to be almost universally agreed that the 49g+ sucks.
Now, if you want to debate about the TI-89 versus the HP 48GX, then we can talk. I *have* used one of those, and I like it a lot better.
It finally died last year (though I hadn't used it seriously in ages).
You could've hired me.
Most professors wouldn't fancy the idea of their students whipping out a palmtop during an exam.
I haven't checked the official tests, but the TI site says: "The TI-89 is allowed for use on the AP* Calculus, AP Statistics, AP Physics, AP Chemistry, PSAT/NMSQT, SAT I, SAT II Math IC & IIC." I apologize if I'm passing on inaccurate information.
I purchased the TI-83 Plus Silver Edition about a year and a half ago. The Processor is 2.5 times faster than the TI-83 Plus it has 24KB RAM and 1.5MB flash memory and it stores up to 94 applications. It also came with a cable to hook it up to an USB port. As far as I can tell, the 84 is nothing more than a repackaged 83 silver edition.
On a good note - despite heavy use I have only had to change the batteries once in the last 1 1/2 years.
when i was in high school, and everybody had their ti-85, quite a few people would write basic apps to solve problems for class. i, however didn't. i just learned how to use the calculator properly, and generally did things using the equation datatype and the built in solver. the people who wrote programs for the same things were generally more interested in telling everybody how they had written this great program to solve for pressure in the ideal gas law than they were in having a good, flexible solution to their problem.
i suppose the moral of the story is that people should lose their damn egos, and learn how to use their tools effectively.
#define F(x) int main(){printf(#x,10,#x);}
F(#define F(x) int main(){printf(#x,10,#x);}%cF(%s))
Bullshit, from the collegeboard website:
Calculator Policy You may use almost any four-function, scientific, or graphing calculator on the SAT I and Math Level IC, and Math Level IIC Subject Tests. You are not permitted to use:
* Hand-held minicomputers or laptop computers
* Electronic writing pads or pen-input devices
* Pocket organizers (PDAs)
* Calculators with QWERTY (typewriter-like) keypads
* Calculators with paper tape
* Calculators that "talk" or make unusual noises
* Calculators that require an electrical outlet
The bolded entry is why the Ti92 is banned and the Ti89 is not.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
You mean like EasyCalc?

Strange how everyone keeps buying the same warmed over retreads from TI.

It's a graphing calculator that doesn't substitute faceplates for real innovation.
My Calculus teacher has had the TI-84 Plus Siver Edition for about two months now, and I've had the chance to play around with it alot. I can tell you that it really is alot faster than my 83 Plus, as I've done speed comparisons as far as graphing is concerneed. They also seem to have refined certain menus with a smaller font, but overall, the OS remains about the same. Not worth the upgrade from the 83, but certainly a plus for people in the market for a new calculator.
