TI-92

The TI-92 was originally released in 1995, and was the first symbolic calculator made by

(CAS) based on Derive, geometry based on 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 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 an additional 128k User memory. 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

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, while physically looking exactly like its predecessor, the TI-92 (which lacked

). 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 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, featuring a list of frequently used commands.


Voyage 200

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

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.

Features


Technical specifications

Note. Official page specifies user-available ROM amount for TI-92 Plus as 702K, but other sources specify it as 388K. This is due to the TI-92 Plus coming with Cabri Geometry pre-installed, which uses the 314 KB difference.
