## About Texas Instruments Calculators

This company has carved a niche with their wide range of calculators. They created ripples with TI 30. It was one of the earlier models of the TI series. The success of the TI 30 encouraged them to manufacture more advanced models. Texas Instruments launched their first graphing calculator with TI 81.

TI 83 was the most popular among the graphing calculators introduced by them. The TI 84 Plus was a more updated version of the TI 83 graphing calculator. The TI graphing calculators made programming an easier task. It also made programming more popular among the students of the 90s. The BASIC interpreter incorporated in the graphing calculators gave the students an opportunity to create BASIC programs.

The TI 85 was the first graphing calculator that made creation of assembly programs possible. The use of the technology called ZShell made this happen. The TI 83 was the pioneering graphing calculator that could work with native assembly. These programs were not as simple as the BASIC programs. Those functions could be compared to that of the modern PDA phones and advanced games.

During the developmental stages of the TI graphing calculator series, personal web pages were grabbing attention. Various companies and their programmers presented websites that featured the web pages. This prompted Texas Instruments to introduce their new feature in the graphing calculators called “webrings”.

The introduction of webrings was followed by the launch of TI Files and ticalc.org. Although communities TI Files no longer exists now, they were immensely popular when they were launched.

Texas Instruments graphing calculators can be subdivided into two categories, the ones using Motorola 68000 and the ones using Zilog Z80. The calculators powered by Motorola 68000 are capable of supporting advanced applications and games.

Some of the best calculators from Texas Instruments like the TI 92 Plus, TI 89 Titanium, and the Voyage 200 use Z80. The Z80 series has witnessed some of the most popular models like the TI 84 Silver and the TI 83 Plus. The Z80 series seems to be more suitable for students.

The latest offering from this innovative company is the TI-Nspire. It is an amazing mathematical software. It also doubles up as a handheld device. Last year this company was honored by World Trade magazine with the Manufacturer of the Year for Global Chain Excellence Award.
