Talk:TI-84 Plus series

Links

While I am very much against random kids posting links to their blogs that have nearly nothing to do with the 84+, some links are being removed that would be helpful to many people visiting this page, simply because they don't provide "any more information." Perhaps a good change would be to divide up the links section into different categories (see the 83x page for what I'm talking about). I'm specifically talking about CalcG.org - the second largest archive of calculator programs and games that I know of, and unlike ticalc.org, it has a help forum, and it can be navigated much more easily. There are even several hundred programs there that are unique to CalcG.org. I'm not affiliated with CalcG.org in any way, so you can assume that this is coming from an unbiased source. If some more people agree with me, why not either divide up the links sections or do something about this?

It should also be noted that it is one of two external websites pointed to by Texas Instruments. (see http://education.ti.com/studentzone/stuff/gamesSoftware.html ). If that's not enough to get a link on the wikipedia article, I don't know what is.

Agreed. CG has been around for nearly 6 years. It has tutorials, a FAQ, and a forum. Anyone looking for information about the TI-84+ would most certainly be interested in tutorials, FAQs and a forum (not to mention the archive of nearly 1,500 files, many of which are exclusive to CG). I'm gonna go ahead and add the link back.--128.187.214.62 20:49, 17 August 2007 (UTC)

TI-84 Plus

Why is this called a "TI-84 Plus" without the existence of an original TI-84?? 66.32.138.124 02:22, 24 Apr 2004 (UTC)

I believe it's mainly to signify that it's a direct improvement over the TI-83 Plus. It's possible that some people might think that a TI-83 Plus was newer than a plain TI-84. Grunt 17:07, 2004 Jun 4 (UTC)

I dont think that this is correct. The school issued calculators we have are orange shelled and are just labelled TI-84. — Preceding unsigned comment added by 74.242.236.251 (talk) 21:14, 1 October 2012 (UTC)

This is incorrect, the school property TI-84 Plus is labelled as such. Mrwompwomp (talk) 15:11, 20 January 2024 (UTC)

TiCalc.org

TiCalc.org no longer points to a useful site, so I have removed its link in the TI-84 series article. -Chrono 04:22, 2 April 2006 (UTC)

Ticalc.org has always been a useful site for calculator programs. Why was it removed? It's a very nice site and deserves to stay here. Austonst 19:41, 23 December 2006 (UTC)

The Original commentor's change has been reverted for a long time.--Ybbor^T 01:31, 24 December 2006 (UTC)

That was the 2006 Ticalc.org April Fool's joke. Had you clicked on any of the links, you would have been taken to the real site. --M1ss1ontomars2k4 (talk) 17:38, 18 July 2008 (UTC)

Vfd for TI-84 (True or false??

True or false: somewhere in Wikipedia, the Vfd of TI-84 will be saved. (Several Vfd's of articles have already been saved, such as Talk:List of flags with one color/Delete. 66.245.93.86 22:06, 15 Sep 2004 (UTC)

It finally got saved. 66.245.0.62 16:58, 16 Sep 2004 (UTC)

Bah, I still prefer the TI-89

full operating system on a calculator, vs the silliness that is the glorified TI-83 plus, I'll take fully programable OS any day, as long as I don't have to pay $180 for it (-; -- anon 03:24, 20 July 2005 (UTC)

Owning both versions of the calculator, I find that the TI-83+ OS is a lot easier to use, and less counter-intuitive than TI-89's exact feature, which often confuses a lot of people when they find that 7/3 is in fact, 7/3 (no suprise there). InvertRect 23:44, 31 August 2006 (UTC)

However, the TI-89 does have a better screen, more advanced interface, algebra solver, no "->" symbol...I could go on for days. --Edlin2 04:41, 17 September 2006 (UTC)

Actually, the 89 does have ->. But what I like about it is more RAM and extra programming capabilities. If only TI didn't fill the almost entire Flash memory with Apps or at least gave more space. --108.86.226.157 (talk) 14:22, 17 March 2012 (UTC)

Hardware Specifications

It would probably make sense to either add hardware specifications to the 84P page, or consolidate the 84P and 83 pages (the 83 page already has a hardware specification listing). I personally think the former makes more sense, but then again the 83 and 83P are consolidated into one page, and they're as equally different as the 83P/84P. I'd say the specification listing is especially important because the way the article is currently worded it makes it sound like the 84P (non-silver) doesn't have a USB port or clock functionality, which it does.

TI-83 Compatablity

I've been looking around for some programs for my TI-84 and I've noticed that a lot of sites with many of the other TI formats but some don't the TI-84 listed. I'm speculating that the TI-84 is compatible with TI-83 programs.

Yes, indeed, it's compatible. I've got a few TI-83 apps running on a TI-84 silver with no problems. --Edlin2 04:42, 17 September 2006 (UTC)

As a note to those asking questions directly pertaining to the calculator's use, please visit ticalc.org, listed in the external links, for information. And yes, it is compatible with TI-83+ programs.

Future of TI graphing calculators

There have been 1-2 models of TI graphing calculators just about every year in the range 1990-2004. Now, however, the TI-84 Plus and TI-89 Titanium continue to be the newest even though it has been 2 years since their release. What happened?? Does TI have any plans?? Georgia guy 00:21, 23 May 2006 (UTC)

      Yes, TI is gearing up to relase the N-spire. I'm not sure if it for sale, but if not they are close. It is designed to replace the Ti 83 family.

Applications?

Should there not be a section for how to get apps on it? samphex 16:21, 2 September 2006 (UTC)

Is it really that difficult? It comes with a manual. Threefingeredguy 10:22, 14 February 2007 (UTC)

Assembly

Added more depth from what I previously wrote about z80 assembly. cjgone2 24 Novemember 2006

Shouldn't there be a section of how to do z80 assembly?

Bugs

I am not sure if this is an appropriate place to put this.
There are two bugs I know of in the TI-84 Plus Silver. The first one is the tangent.

You will get a zigzag pattern.
The other glitch is the unability to use GraphStyle.
Sodaplayer 02:59, 17 January 2007 (UTC)

If you're talking about not graphing discontinuities, then that is not a bug, it was added to version 2.30 of the operating system. -Dlrohrer2003 16:49, 31 October 2007 (UTC)

To say the least it's not a bug! It's supposed to be graphed without discontinuities; if the OP didn't know that, perhaps he or she should have paid more attention in math! As for GraphStyle, it works perfectly fine; I checked it myself. --M1ss1ontomars2k4 (talk) 17:41, 18 July 2008 (UTC)

Late to the point, but perhaps previous should have paid more attention to TI graphing calculators! Many (most?) graphing calculators drew vertical lines where asymptotes should be. Users of old version of even this calculator had(have) to be careful to check their math, because asymptotes could not realiably be detected graphically. —Preceding unsigned comment added by 208.83.118.230 (talk) 19:53, 27 October 2009 (UTC)

Money

How mush does this series cost.162.84.139.48 21:50, 5 November 2007 (UTC)

• TI-84 Plus - $129.99
• TI-84 Plus Silver Edition - $149.99

RAM

24 KB RAM (128 KB on Silver Edition, however the extra 96 KB is not user accessible by default)

Does that mean it's accessible with some 3rd party addon program? Or just that TI hasn't implemented it in the OS and there's no way to use it? Maybe this should be clarified in the article.

No, this RAM is used when a Flash APP is transfred to it in order to run-Luby —Preceding unsigned comment added by 75.135.76.253 (talk) 03:14, 9 February 2008 (UTC)

Processor

I do believe that this calculator normally runs on 6Mhz mode, but is able to be turned on to 15Mhz mode. Shouldn't this be added the page? -Luby —Preceding unsigned comment added by 75.135.76.253 (talk) 03:16, 9 February 2008 (UTC)

No, it normally runs in 15MHz mode when doing calculations (note the capitalization--the H is capitalized because the original symbol for Hertz is Hz). When assembly-language programs are run, the calculator switches to 6 MHz to maintain compatibility with games and other programs requiring 6 MHz timing. This can be toggled with a BCALL, if i'm not mistaken... --M1ss1ontomars2k4 (talk) 17:36, 18 July 2008 (UTC)

Solve =

I am not sure if teachers or much of the public knows about the solve statement programmed into the calculator. Im also wondering if any teachers know of its existence. Its very handy. (Im not talking about the Solver programmed already on there, Im talking about the solve(Y1-Y2,X,1.)

You just put the left side of the eq into Y1 and the right into Y1 and it solves for X after you complete the statement above. Its better than whats programmed in already cause one side does not have to be zero.DelvarMe (talk) 16:40, 11 April 2008 (UTC)

This is the same as the graphical solver (2nd Calc intersection) already present. The syntax for the solve() command is equation that equals zero, the independent variable, and a guess. The calculator will substitute values approximately equal to your guess until finds a number that causes the equation to equal zero. If you already have a guess, then the solve() feature is more handy than graphing and zooming in/out until you see the intersection. If you don't already know what to put for a guess, then you might as well just use the graphical version. --M1ss1ontomars2k4 (talk) 17:34, 18 July 2008 (UTC)

RAM - revisited

24 KB RAM (128 KB on Silver Edition, however the extra 96 KB is not user accessible by default)

I am pretty sure 84-Plus AND 84-Plus SE have the same RAM chip, although on many other 3rd party sites the SE is the only recognized for 128 KB. (I have interacted with the extra RAM as well as used other APPs that use this RAM without any problems) comment added by Nyquist562 (talk) 03:14, 4 August 2008

Assembly Language

For some reason this:

"Unfortunately the TI-84 will be made exam illegal for GCSE, GCE AS & A Level exams starting in 2009."

was in the assembly language section. I do not think that that is the appropriate section 98.221.116.93 (talk) 22:27, 20 January 2009 (UTC)

Sections

Should we split the introduction into a TI-84+ section and a TI-84+SE section, and replace it with a more brief description? The TI-83 series article already follows this scheme. Nerdygeek101 (talk) 18:53, 24 May 2009 (UTC)

Assembly Code?

I don't think that an example of code should be included in the article. Examples analogous to the one in this article don't exist in any other Texas Instruments calculator article. Also, it doesn't add any sort of understanding of the calculator series. I think that just the paragraph mentioning assembly is good enough. I've deleted the section of code; if you don't agree then undo and give your argument.Shoveldude (talk) 03:41, 6 January 2010 (UTC)

Display

The TI-84 Plus features and advertises an 'improved' screen. Having used the TI-83 and the TI-84, I can verify this, as can TI's website. However, Wikipedia doesn't mention this, nor does it mention what kind of screen. Could somebody fix this? 24.32.205.164 (talk) 08:16, 19 April 2010 (UTC)

TI-84 serial number/RAM connection

I added a reference for the statement: "All calculators with the letter H or later as the last letter in the serial code have less ram pages causing some programs to fail." Unfortunately, the best I could do was a trial of several different calculators (with different last letters in the serial number) that was posted on the forum. I know it's not ideal, and I won't start an edit war if someone puts a different link up. This is only temporarily used as a source until someone can use a vetter reference. cymru lass ^{(hit me up)}⁄_{(background check)} 00:32, 29 May 2010 (UTC)

TI-84+C

http://www.engadget.com/2012/11/13/texas-instruments-confirms-color-ti-84-calculator-is-on-track-f/

Is this news site often wrong?? Georgia guy (talk) 00:12, 25 November 2012 (UTC)

I didn't realize Wikipedia already had this calculator mentioned! This is surprising, because we know the sequence:

1. TI-81
2. TI-82
3. TI-83
4. TI-83 Plus
5. TI-84 Plus
6. TI-Nspire with Clickpad
7. TI-Nspire with Touchpad
8. TI-Nspire CX

The next member should be an upgrade to the TI-Nspire CX, but it looks like it's wrong. It's the TI-84 Plus C. Georgia guy (talk) 00:15, 25 November 2012 (UTC)

Proposition to Merge Article with TI-83 Series

I feel that this article should be merged with TI-83 series because the two calculators are really one big series. It would also help people compare the technical details of the whole line by having the two pages merged together. — Preceding unsigned comment added by 2601:249:D00:78:BD74:2AB2:1585:F3CE (talk) 01:06, 5 February 2017 (UTC)

As someone familiar with the series, the TI-83+ and TI-84+ are similar enough to group in the same article, but not the TI-83. The 83 is substantially different from the 83+ and considering how similar it looks, I think that's important for consumers to understand.164.47.161.128 (talk) 18:24, 24 October 2019 (UTC)

Usage

Is the TI-84 as widely used in high school math classes as it seems? I would like to find a reliable source for this but all I have been able to find is blogs without hard numbers. Ungulates (talk) 17:25, 16 July 2020 (UTC)

Proposal to move the TI-84+CE section to the TI-83 Premium CE page

Hardware-wise, the TI-84 Plus CE is very different from previous models in the TI-84 Plus series, as it uses an eZ80-based architecture rather than a Z80-based one. The 84+CE is nearly identical to the TI-83 Premium CE, its French variant, which already has its own page. Additionally, a Python-enabled variant of the TI-84+CE will release soon, which will further make it more similar to the 83PCE than to the previous calculators in the TI-84 Plus line.

In my opinion, the CE calculators should thus both be on one page, separate from the rest of the 84+ line. --Commandblockguy (talk) 20:27, 20 June 2021 (UTC)
