TI-84 Plus series

Graphing calculators TI -84 Plus

Mini - USB, 2.5 mm jack

Programmable in TI -Basic and Z80 Assembler

The TI -84 Plus is a graphing calculator of the American semiconductor and electronics giant Texas Instruments. The first model was launched in 2004. The naming conventions of Texas Instruments According designated "Plus" that a flash ROM memory is installed. The TI- 84 Plus is the successor to the TI- 83 Plus (1999) and is compatible with any TI -83 Plus program compatible, but has almost three times the storage capacity ( in the variant " Silver Edition " even more than nine times as much ). The TI- 84 Plus and TI -84 Plus Silver Edition have both a clocked with 15 MHz " Zilog Z80 " processor.

Features

The TI -84 Plus can be connected to a computer or other TI -84 Plus / Plus Silver Edition by mini USB, 2.5mm jack socket exists for connecting to a TI -83 (Plus) or TI -82 ( Stats ). The so-called teacher version of the TI -84 Plus Silver Edition has still above a wide connector for connecting a viewscreen said transparent liquid crystal overlay to project the screen contents by means of an overhead projector. The current version of the operating system for the TI -84 Plus is 2.55MP.

Programming

The TI -84 can be programmed using both TI- Basic and Z80 assembler. A possible variant of the Assemblierens but difficult is that a TI- Basic program is created, which is constituted as follows:

: AsmPrgm   " Program code in hexadecimal " Thus, the programmer must the entire instruction set have in stock or can memorize. One danger is that an incorrect command can make the TI unusable ( overwriting memory ) and also that an incorrect command resets the TI -84 Plus immediately to the factory state, whereby the program is lost. With AsmComp () assembler programs can be compiled and executed with asm ().

Developments

• TI -84 Plus Silver Edition offers more user memory (1.5 MB).
• An advanced software emulation for Windows and Mac is SmartView for TI -84 Plus.
• TI -Nspire with Clickpad can emulate a TI -84 Plus Silver Edition by an additional interchangeable keyboard.
• TI -84 Plus Silver Edition C as a variant with 65,000 -color display and backlight and proprietary lithium -polymer battery.
