Released in 1996, it is one of the most used graphing calculators for students (especially those in middle school or higher). In addition to the functions present on normal scientific calculators, the TI-83 includes many features, including function graphing, polar/parametric/sequential modes, statistics, trigonometric, and algebraic functions. Although it does not include as many calculus functions, applications (for the TI-83 Plus -- see below) and/or programs can be downloaded from various websites that allow for them.
The TI-83 was replaced by TI with the TI-83 Plus calculator in 1999, which included Flash ROM, enabling the device's operating system to be updated if needed, or for large new Flash Applications to be stored, accesssible through a new (Apps) key. The flash rom can also be used to store user programs and data. In 2001 the ante was raised with the TI-83 Plus Silver Edition, which featured approximately nine times the available Flash ROM, and twice the processing speed (12 MHz) of a standard TI-83 Plus, all in a translucent, iridescent grey case.
The original TI-83 is itself an upgraded version of the TI-82.
An interesting historical note: the TI-83 was the first calculator in the TI series to have built in assembly language support. (The TI-85 and TI-82 had ASM support, but only after sending a specially constructed (hacked) memory backup.) The support could be accessed through a hidden feature of the calculator. Users would write their assembly (ASM) program on their computer, compile it to a hexadecimal form, and send it to their calculator as a program. The user would then execute the command "Send(9prgmXXX", and it would execute the program. Successors of the TI-83 replaced the Send(9 backdoor with a less-hidden Asm( command.
The TI-83 Plus is a graphing calculator made by Texas Instruments, designed in 1999 as an upgrade to the TI-83. The TI-83 Plus is one of TI's most popular calculators. It uses a ZiLOG Z80 microprocessor running at 6 MHzA megahertz (MHz is one million (106) hertz, a measure of frequency. Megahertz in radio When used in the context of radio, MHz refers to the number of oscillations of electromagnetic radiation. Severel parts of the radio spectrum fall into the MHz range:, a 96x64 monochrome LCDFor other meanings of LCD, see LCD (disambiguation). polarize the light as it enters. Glass substrate with ITO electrodes. The shapes of these electrodes will determine the dark shapes that will appear when the LCD is turned on. Vertical ridges are etched screen, and 4 AAA batteriesAAA battery" may also be an abbreviation for " antiaircraft artillery battery An AAA battery is 44. 5 mm long and 10. 5 mm in diameter, weighing around 11. Output of alkaline batteries in this size is 1. 5 volts, 900 to 1,155 mAh. The battery is also clas as well as backup CR1616 or CR1920 battery. A link port is also built into the calculator. The main improvemnt over the TI-83 however was the addition of 160 KBThe kilobyte comes in two flavours, depending on the context in which it is used, meaning either 1,000 or 1,024 bytes. The kilobyte (kB) This uses the SI prefix kilo, and simply refers to 1,000 bytes (as a kilometre equals 1,000 metres). This is the notat of Flash ROM, which allowed for OS bugfix upgrades, program archiving, and support for advanced flash applications (Apps).
Designed for high school, it contains all the features of a scientific calculator as well as function, parametric, polar, and sequential graphing capabilities, an environment for financial calculations, matrix operations, on-calc BASIC programming, and more. Symbolic manipulation (differentiation, algebra) is not built into the TI-83 Plus, but is available as an addon by Detached Solutions. You can also make programs on it using a language called TI-BASIC which is similar to the langauge BASIC use by computers. You can also program in language called TI-ASM or TI Assembly, which is faster.
An active but small community of third-party developers exists and a large archive of various programs for it can be found at ticalc.org. The most prominent group of developers is known as Detached Solutions.
In 2001, TI released the TI-83 Plus Silver Edition, which was basically the same calculator, but with a 15 MHz processor and 1.5 MB of Flash ROM.
As of Spring 2004, the TI-83 Plus has been officially replaced by the TI-84 Plus, which offers a 15 MHz processor and roughly three times the memory of the TI-83 Plus.
