The '''TI-92 series''' are a line of [[graphing calculator]]s produced by [[Texas Instruments]]. They include: the '''TI-92''' (1995), the '''TI-92 II''' (1996), the '''TI-92 Plus''' (1998) and the '''Voyage 200''' (2002). The design of these calculators includes a [[QWERTY]] keyboard. Because of this keyboard, they are given the status of a "[[computer]]" rather than a "[[calculator]]" by [[United States|American]] testing facilities and cannot be used on tests such as the [[AP Exams]] while the [[TI-89]] models can be used.<ref>{{citation|url=https://collegereadiness.collegeboard.org/sat/taking-the-test/calculator-policy|title=Calculator Policy|date=13 January 2016}}</ref><ref>{{citation|url=https://apstudent.collegeboard.org/takingtheexam/exam-policies/calculator-policy|title=AP Calculator Policy}}</ref>

==TI-92== The '''TI-92''' was originally released in 1995, and was the first symbolic calculator made by [[Texas Instruments]]. It came with a [[computer algebra system]] (CAS) based on [[Derive computer algebra system|Derive]], geometry based on [[Cabri Geometry|Cabri II]], and was one of the first calculators to offer 3D graphing. The TI-92 was not allowed on most standardized tests due mostly to its QWERTY keyboard. Its larger size was also rather cumbersome compared to other graphing calculators. In response to these concerns, Texas Instruments introduced the [[TI-89]] which is functionally similar to the original TI-92, but featured [[Flash ROM]] and 188 [[kilobyte|KB]] RAM, and a smaller design without the QWERTY keyboard. The TI-92 was then replaced by the TI-92 Plus, which was essentially a TI-89 with the larger QWERTY keyboard design of the TI-92. Eventually, TI released the [[Voyage 200]], which is a smaller, lighter version of the TI-92 Plus with more Flash ROM. The TI-92 is no longer sold through TI or its dealers, and is very hard to come by in stores.

==TI-92 II== The '''TI-92 II''' was released in 1996, and was the first successor to the [[TI-92]]. The TI-92 II was available both as a stand-alone product, and as a user-installable II module which could be added to original TI-92 units to gain most of the feature improvements. The TI-92 II module was introduced early in 1996 and added the choice of 5 user languages (English, French, German, Italian and Spanish) and almost doubled the User memory to 128k. Along with the TI-92, the TI-92 II was replaced by the TI-92 Plus in 1999, which offered even more Flash ROM and RAM.

==TI-92 Plus== {{Infobox Calculator | name = TI-92 Plus | image = ti-92plus.jpg | caption = TI-92 Plus | type = [[Programmable calculator|Programmable]] [[Graphing calculator|Graphing]] | entry = [[Calculator input methods#Mathematical display|D.A.L.]] | introduced = 1998 | discontinued = 2006 | latest_firmware = 2.09 | predecessor = TI-92/TI-92 II | successor = Voyage 200 | manufacturer = | precision = 14 | display_type = [[Liquid crystal display|LCD]] [[Dot-matrix]] | display_size = 240x128 | prog_lang = [[TI-BASIC]] | processor = [[Motorola MC68000]] | frequency = 12MHz | memory_user = | memory_data = 188 kB RAM 702 kB flash memory | memory_step = | weight = {{convert|493|g|oz}} | dimensions = {{convert|4.7|x|8.2|x|1.20|in|mm|abbr=on|disp=flip}} | supply = 4 [[AA battery|AA]]s, 1 [[Button cell|CR2032]] }}

The '''TI-92 Plus''' (or '''TI-92+''') was released in 1998, slightly after the creation of the almost-identical (in terms of software) [[TI-89 series|TI-89]], while physically looking exactly like its predecessor, the TI-92 (which lacked [[flash memory]]). Besides increased memory over its predecessor, the TI-92 Plus also featured a sharper "black" screen, which had first appeared on the TI-89 and which eases viewing.

The TI-92 Plus was available both as a stand-alone product, and as a user-installable Plus module which could be added to original TI-92 and TI-92 II units to gain most of the feature improvements, most notably Flash Memory. A stand-alone TI-92 Plus calculator was functionally similar to the [[TI-89 series#Hardware versions|HW2]] TI-89, while a module-upgraded TI-92 was functionally similar to the HW1 TI-89. Both versions could run the same releases of operating system software.

As of 2002, the TI-92 Plus was succeeded by the Voyage 200 and is no longer sold through TI or its dealers.

The TI-92 Plus is now available in an online emulator,<ref>{{Cite web|title=TI-89 / TI-92+ / TI-V200 / TI-89T emulator (beta version 12-debrouxl)|url=https://tiplanet.org/emu68k_fork/|access-date=2020-12-15|website=tiplanet.org}}</ref> featuring a list of frequently used commands.<ref>{{Cite web|title=TI-89 Graphing Calculator For Dummies Cheat Sheet|url=https://www.dummies.com/education/graphing-calculators/ti-89-graphing-calculator-for-dummies-cheat-sheet/|access-date=2020-12-29|website=dummies|language=en}}</ref>

==Voyage 200== {{Infobox Calculator | name = Voyage 200 | image = Voyage200.jpg | caption = | type = [[Programmable calculator|Programmable]] [[Graphing calculator|Graphing]] | entry = [[Calculator input methods#Mathematical display|D.A.L.]] | introduced = 2002 | discontinued =2014 | predecessor = TI-92 Plus | latest_firmware = 3.10 | manufacturer = | precision = 14 | display_type = [[Liquid crystal display|LCD]] [[Dot-matrix]] | display_size = 240x128 | prog_lang = [[TI-BASIC]] | processor = [[Motorola MC68000]] | frequency = 12MHz | memory_user = | memory_data = 188 kB RAM 2.7 MB flash memory | memory_step = | weight = {{convert|272|g|oz}} | dimensions = {{convert|4.6|x|7.3|x|1.10|in|mm|abbr=on|disp=flip}} | supply = 4 [[AAA battery|AAA]]s, 1 [[Button cell|CR1616]] or [[Button cell|CR1620]] }}

'''Voyage 200''' (also '''V200''' and '''Voyage 200 PLT''') was released in 2002, being the replacement for the TI-92 Plus, with its only hardware upgrade over that calculator being an increase in the amount of flash memory available (2.7 [[megabyte]]s for the Voyage 200 vs. 702 [[kilobyte]]s for the TI-92 Plus). It also features a somewhat smaller and more rounded case design.

Like its predecessor, Voyage 200 is an advanced calculator that supports plotting multiple functions on the same graph, parametric, polar, 3D, and differential equation graphing as well as sequence representations. Its symbolic calculation system is based on a trimmed version of the calculation software [[Derive computer algebra system|Derive]]. In addition to its algebra and calculus capabilities, the Voyage 200 is packaged with list, spreadsheet, and data processing applications and can perform [[curve fitting]] to a number of standard functions and other [[statistics|statistical analysis]] operations. The calculator can also run most programs written for the [[TI-89]] and TI-92 as well as programs specifically written for it. A large number of applications, ranging from [[video game|games]] to interactive [[periodic table]]s can be found online.

The V200 is easily mistaken for a [[personal digital assistant|PDA]] or a small computer because of its large enclosure and its full QWERTY keyboard — a feature which disqualifies the calculator for use in many tests and examinations, including the American [[ACT (examination)|ACT]]<ref name="ACTpolicy2025">{{cite web |title=ACT Calculator Policy |url=https://www.act.org/content/act/en/products-and-services/the-act/test-day/calculator-policy.html |access-date=1 May 2026}}</ref> and SAT.<ref name="SATpolicy2025">{{cite web |title=SAT Calculator Policy Flyer |url=https://satsuite.collegeboard.org/media/pdf/sat-calculator-policy-flyer.pdf |publisher=College Board |access-date=1 May 2026}}</ref> The [[TI-89 Titanium#TI-89 Titanium|TI-89 Titanium]] offers exactly the same functionality in a smaller format. All calculators with computer algebra systems are illegal on both the SAT test and the ACT test.
