Should this page be moved to "TI-89 and TI-92" or something (with redirects from both calculators)? Each calculator needs only about a paragraph of differentiation.... Paullusmagnus 17:31, 18 Aug 2003 (UTC)

Someone should check the information about ams-dev, I can't find anything on it anywhere else on the net. In fact, googling "ams-dev" and "TI-89" returns one page - the Wikipedia article. Sam5550 01:18 15 Oct 2003 (UTC)
Can we move the TI-89 Titanium header of this article because the TI-89 Titanium has its own article?? Any objections?? 66.245.80.45 16:15, 18 Sep 2004 (UTC)

I saw a section on the TI-89 Plutonium here a while ago. Was that for real? I was at ARML when they announced they were giving out TI-89 Plutonium calculators to the third place team: Lehigh Valley Fire. The whole auditorium was pretty surprised, and I haven't found anyone who knows whether this was a mistake or if it is really in the pipeline. Any insights? 69.117.13.253 03:05, 15 June 2006 (UTC) ARML NassauA
I've never heard of "case swapping". Does this happen in the real world? The Slimey 02:44, 14 April 2006 (UTC)
Can anyone provide a source for this or is it just original research cruft. savidan(talk) (e@) 08:20, 14 April 2006 (UTC)
"Case swapping" does exist. I know, first hand, "at least" ten kids who have done so themselves. I do, however understand that Wikipedia is not an instruction manual. Therefore, I will re-post the "Case-Swapping" section and leave out the instructions on how to do so. I hope you respect my descion to spread this knowledge and not remove my contribution again. Thank You
Texas Instruments' website refers to the calculator by the name "TI-89", so that is the name that should be used throughout the article Dav2008 01:40, 15 June 2006 (UTC)
Perhaps it would be worth while mentioning its syncing software TI Connect. I've worked a little with the article and I think adding a link would be approprate, as it is one of the features (the ability to download new software) to the TI89 or any other TI calculators that support this function.

How in the world does the shape of the keyboard determine whether something is a "computer" or not? —Preceding unsigned comment added by 130.13.76.192 (talk • contribs)
Someone should post an external link to an asm patch for hw4. All I've been able to find are the outdated patches for hw2 and 3. Does anyone know where I can obtain this patch? --Nintendorulez talk 21:33, 12 September 2006 (UTC)
The cases of the TI-89 and TI-84 Plus can NOT be swapped, as the shape of the buttons at the top is different. I've edited this information out of the article.
The case of the TI-98 Titanium and the case of the TI-84 Plus/Silver can be switched with out any trouble. --Harrisonhjones 02:32, 14 December 2006 (UTC)
Can someone explain why this article consists mostly of the calculator's ability to perform/simplify algebraic and trigonometric expressions? Many calculators can do this, and it is certainly not the primary function of the machine. 130.134.81.16 20:52, 18 July 2007 (UTC)
I changed the phrase "switching on" to "turning on" because I personally had to reread the sentence several times to understand the meaning. "Switching" is poor word choice to describe powering the calculator on, as the entire section pertains to "switching" the cases of calculators in the first place. To avoid this problem, I changed the phrase to something less confusing. It looks like it's since been changed back and I'm not sure why anyone would think it's better the way it was. (My apologies if I'm not following conventions with this comment, this is my first time using a talk page. I rarely edit anything on the site besides typos and word choice.) 71.58.102.233 17:20, 8 August 2007 (UTC)
Even thought this is probably pushing tombstones.. both are valid.. switching is derrived from the action of moving the blade of a switch.. as in "switching the position of the on/off switch", and turning was taken from the early light switches in homes, and engines. Early light switches were screw type terminals, where you turn the plastic/baccalite knob until two internal metal plates made contact.. hence "turning on or off the light". —Preceding unsigned comment added by 216.221.32.105 (talk) 03:09, 2 September 2009 (UTC)
Would anyone here be offended if I changed the block to , since that's how my 89 Titanium displays it? --T3thys::ben (talk) 06:09, 30 December 2007 (UTC)
I'm here wondering about the case swapping section. Should we delete it altogether or put it in a more appropriate article such as the graphing calculator or case modding. My thoughts on moving the section are that it seems too generalized to be in an article about a specific calculator model and should go elsewhere if there is enough reliable sources about it. Any ideas? - Dlrohrer2003 20:14, 15 September 2008 (UTC)
Er ... it has certain technically "32 bit" features (mainly a certain pair of registers), but even the most charitable observers usually put it in the 16-bit category - given the data bus width and most internal data operations are 16-bit, it only has 24-bit memory addressing (same as the 80286 (and crippled may-as-well-be-a-16-bit 386SX)), etc, etc. I don't see many opining that the original Mac, Atari ST, Amiga, Genesis etc are 32-bit machines. Motorola's 32-bit era didn't really kick off until the 68020 came along. So can I change that "32" to a "16"? After all, a 10mhz, cycle-efficient-instruction-set 16 bit processor with 256kb of working memory and 2mb of program storage still puts it streets ahead of a lot of the (Z80-based) opposition... 146.90.199.209 (talk) 01:27, 25 April 2013 (UTC)
What matters is that it implements a 32bit Instruction Set Architecture (the one named after itself, 68000), thus it is a 32bit CPU. Implementation details "it has a 16bit ALU inside" or "it communicates over a 16bit bus outside" are actually just implementation details. Today we have CPUs implementing RV64GC with flexible 4-64bit ALUs to fit a range of FPGA sizes (which doesn't make them 4-64bit CPUs), and microcontroller chips without a CPU bus outside (which doesn't make them 0bit CPUs). Only the ISA matters for calling a CPU 32bit or else.37.133.96.191 (talk) 22:16, 7 October 2020 (UTC)
The online version of TI-89 Titanium is named TI-89 Online Simulator. The name is not Emulator
source: https://ti89-simulator.com/
TI-89 Online Simulator has the same features as the calculator.

I noticed that the "Hardware versions" subsection has no citations whatsoever. As I'm unfamiliar with Wikipedia customs, I won't add references to https://web.archive.org/web/20230606134357/http://tict.ticalc.org/docs/J89hw.txt (the original went down last week) or https://debrouxl.github.io/gcc4ti/ as neither (especially the first & more useful page) probably qualify as a reliable source. Out of my experience with these devices, I don't know of any better sources for the subsection though. Asdf2jkl (talk) 01:03, 31 October 2023 (UTC)
