The TI-83 Plus added Flash technology to the TI-83 Graphing calculator. This technology gives you the flexibility to add calculator software applications and additional functionality beyond math and science, providing long-term value.
These reasons and more have made the TI-83 Plus the best selling graphing calculator in the US and Canada. In the year 2000 more than 2,000,000 units were shipped! Already on July 22, 2003 reported Texas Instruments an accumulated shipment of 25,000,000 graphing calculators since the introduction of the TI-81.
The hardware of the TI-83 Plus is similar to a lot of other products: An 8-bit microprocessor of the Z80 family, a huge Flash-ROM of 512k Byte capacity, a RAM of 32k Byte size and a driver for the LCD display. You'll find similar architectures with just another balance of RAM and ROM capacity:

Specific CPU was replaced by a two-chip approach
Manufacturing several millions
calculators every year justifies even minor changes of an existing design
to lower the BOM or raise the profit. We noticed several changes in the
hardware of the TI-83 Plus between its introduction in 1999 and the
current (2007) production following a simple pattern:
• Higher integration: Two
generations of ASIC’s combine the Z-80 CPU, support ASIC, discrete
logic and RAM.

Glitter-packed and translucent, this is how Texas Instruments described the wonderful TI-83 Plus Silver Edition in its press release dated June 19, 2001. Already for the Back-to-School campaign 2001 retailed Target started to sell the TI-83 Plus Cool Blue, in 2002 the TI-83 Plus Ultra Violet and in 2003 the TI-83 Plus Blue. In 2004 we got from Staples the wonderful TI-83 Plus Lime Green and a Blue version. In 2007 Target introduced a nice looking TI-83 Plus Light Blue. Texas Instruments surprised the French market in 2006 with a translucent TI-83 Plus Cool Blue, changed the design in 2007 and introduced a strange looking TI-83 Plus Pink. Starting in 2004 six different Color Slide Cases were sold for the TI-83 Plus and compatible calculators TI’s Education Technology Store.
A serial port of the calculators allows the connection to the Calculator-Based Laboratory system CBL, its successor CBL 2, the Calculator-Based Ranger CBR and its successor CBR 2. Texas Instruments announced June 2002 an optional full-sized QWERTY Keyboard for a more convenient entry of notes into the handhelds.
Don't miss the TI-73 - obviously based on the TI-83 Plus. We prepared together with fellow collector Xavier Andréani a comprehensive comparison of entry level graphing calculators, to shed some light on the different specifications of the TI-82 and TI-83 / TI-83 Plus based products.
The TI-83 Plus traces back to the Casio fx-7000G, the world's first Graphing calculator.
Texas Instruments announced January 7, 2004 with the TI-84 Plus the successor of the TI-83 Plus. Main differences are:
• More stylish housing
• Integrated USB port for computer connecitivity
• Internal clock
• Three times of user memory
• 15 MHz CPU clock instead 6 MHz
• Advanced display
• 13 pre-loaded software applications
The TI-83 Plus was mentioned in TI's press release dated August 15, 2002 to celebrate the 35th anniversary of its invention of the electronic calculator.

DALLAS, January 11, 1999
Texas Instruments today introduced the
TI-83 Plus, an upgradable graphing calculator designed for high school and
lower level university math and science courses. The TI-83 Plus features
all the functionality of the TI-83 - TI's most popular graphing calculator
- enhanced with FLASH™ ROM technology for electronic upgradability, new
applications and six times more user available memory. The announcement
was made at the American Association of Physics Teachers conference in
"Teachers and students indicated a real need for a calculator that can be updated as new applications are developed and the curriculum evolves," said Tom Ferrio, vice president of Texas Instruments. "We've taken our most popular graphing calculator and made it even better. The TI-83 Plus, with its additional FLASH™ ROM memory, can be electronically upgraded and customized to better fit changing classroom needs. This technology will provide teachers and students more flexibility in exploring mathematical and scientific concepts."
"TI has done a really good job of
designing the TI-83," said Allan Bellman, mathematics instructor at
Same Functionality and Compatibility:
The TI-83 Plus includes all of the TI-83 capabilities but with a change in only two keyboard placements. The similarity in design will enable the TI-83 Plus to work side-by-side in the classroom with the TI-83. In fact, the TI-83 Plus can receive all data types - such as lists, programs and matrices - from the TI-83 and send all common data types to the TI-83.
Upgradability and Additional Applications:
The TI-83 Plus uses FLASH™ ROM technology, which allows users to install software upgrades through the communication port. The latest software version can be downloaded from the TI website to the user's computer, then to the TI-83 Plus via a TI-GRAPH LINK™. Instead of having to buy an entirely new calculator, users can simply buy the software upgrade, which will cost less than the price of a new machine.
The TI-83 Plus comes with a built-in application to collect and analyze data from the Calculator-Based Laboratory™ (CBL™) and Calculator-Based Ranger™ (CBR™) accessories. This allows users to quickly and easily conduct real-time, interactive data collection experiments with time, distance, temperature, light intensity, voltage, velocity and acceleration. Applications to be made available include language localization, an application that allows users to select what language the calculator will operate in, and an Interactive Graphing application that will enable users to visualize how changing a mathematical function's parameters affect its graph. Vernier Software will also convert two of its popular, multi-purpose CBL programs -- CHEM/BIO and PHYSICS -- to FLASH™ ROM applications programs for the TI-83 Plus, allowing users to record and analyze two times more real-world data than the TI-83. Applications will be made available via the World Wide Web as TI and other leading software developers create them. "The sky is the limit on the possible applications that can and will be developed," added Bellman.
TI-83 Plus has six times more user memory than the TI-83. The calculator includes 24K of RAM, but also includes 160K of data archive memory used to store data, programs and additional applications that can be recalled later but which are not stored in the active user memory. "The additional memory will allow me to store a lot of information as I teach different courses throughout the day," said Bellman. "If I have done a data exercise with my first period algebra class and want to continue the discussion the next day, I can save all my work by going to the memory manager and selecting the "group" option, thus saving me from a lot of rework."
In addition to the data and program storage, the 160K user data archive can be used to store and execute up to 10 calculator software applications, giving users control over how the memory is used. They can choose how much is used for applications and how much is used as personal storage.
Suggested courses for the TI-83 Plus include algebra, trigonometry, calculus, statistics, physical science, physics, chemistry and biology.
The TI-83 Plus comes with a unit-to-unit link cable to connect it with another TI-83 Plus or TI-83. The TI-GRAPH LINK™ accessory cable, which may be purchased separately, allows connection of the TI-83 Plus to a computer.

Has Screenagers Screaming for More With the Sale of its 25 Millionth
Most pervasive form of technology in today's classrooms provides educational value and enhances "cool" learning for teens around the world
DALLAS, July 22, 2003Just how much is 25 million? To put it into perspective, you'd have to circle the earth more than 1,000 times to travel 25 million miles, or walk up and down the Empire State Building 6,720 times to take 25 million steps. Or you could count the number of graphing handhelds that Texas Instruments, the leader in handheld educational technology, has put into the hands of teachers and students around the world. TI has sold its 25 millionth graphing handheld, reflecting the popularity and longevity of these learning devices.
According to the U.S. Census Bureau's 2000 Census, there are approximately 24.3 million people between the ages of 14 and 19 in America today. These Generation Y teens, also known as screenagers due to their heavy use of technology, have a large appetite for the "cool factor" and are demanding maximum versatility and power from their handhelds.
Since their introduction into the classroom in 1990, TI's educational tools have evolved to meet students' needs both in and out of the classroom. They are customizable to fit teens' individual styles and tech preferences, and they pack more speed and functionality than ever before. Above all else, these devices continue to enable students to gain a deeper understanding of concepts as they learn and provide them a visual representation of lessons and curriculum.
"TI's commitment to providing true educational value has driven us to expand the handhelds use beyond traditional math and science into other subject areas such as English and Social Studies," said Tom Ferrio, vice president of Texas Instruments Educational & Productivity Solutions. "Similarly, the graphing handheld has evolved over the years, with teens' passion for technology driving the visual appearance and lifestyle applications. Our technology has impacted teens across the world by helping them learn and understand academic concepts, as well as familiarize them with technology in general."
Educational devices that used to be just for school have made a strong foray into the cool realm. For example, the TI-83 Plus Silver Edition, TI's newest graphing handheld, comes preloaded with software applications such as a periodic table of elements, spread sheet application, electronic study cards for self quizzing, and an organizer and address book. Teens can personalize their handhelds with color cases, add-ons such as a full-size keyboard for note taking and downloadable software from the Internet.
TI graphing handhelds are applicable in a variety of subject areas spanning math and science to language arts, history and world languages. They are available at discount, electronics and office supply stores nationwide.
