Graph 89 is an emulator for the TI-83, TI-83 Plus, TI-83 Plus Second Edition, TI-84 Plus, TI-84 Plus Second Edition, TI89, TI89 Titanium, TI92 Plus and  Voyage 200 calculators.

*Please remember to read the ROM section below before downloading this application!

It will turn your phone or tablet into an exact replica of your calculator. The emulator will provide the same functionality and generate the same results as your real calculator. Being ported to Android means that it will always fit in your pocket, have a backlight, be rechargeable and also run faster.

You would be able to install applications by copying the App file to the internal memory of your phone, pressing the 'Back' button and selecting 'Install Application/Send File'.

Graph89 would be great tool  for math, science and engineering courses in high school, college and beyond. Some of these calculators feature Computer Algebra System (CAS) having the capability to simplify and symbolically solve mathematical expressions.

Graph89 combines two powerful emulation engines which make it the only app in the Android Play Store to support the full range of TI graphing calculators.

1) TiEmu -http://lpg.ticalc.org/prj_tiemuproviding support for the Motorola 68K family: TI89, TI89 Titanium, TI92 Plus, Voyage 200

2) TilEm -http://lpg.ticalc.org/prj_tilemproviding support for the Z80 family: TI 83, TI 83+, TI 83+ SE, TI 84+, TI 84+ SE

!!! IMPORTANT !!!

ROM:

Emulators are computer software which simulate a specific hardware. In order for the emulator to do anything useful it needs some software to run. The software that runs in your calculator (ROM) is copyrighted by TI, and as such, it can not be distributed by Graph89 or any other emulator for that fact.

This means that you will have to provide the ROM file yourself by extracting it from your own calculator. Transfer it to your phone, and then tell Graph89 where to find it. To extract the ROM you can follow the instructions fromhttp://www.ticalc.org/programming/emulators/romdump.htmland by using TiLPII fromhttp://sourceforge.net/projects/tilp/filesGoogle and youtube are also great sources of tutorials and help.

Wabbitemuhttp://wabbit.codeplex.com/is also a great tool for extracting the ROM from your TI83/TI84

Supported ROM files:

TI89, TI89 Titanium, TI92 Plus and  Voyage 200: 

 *.rom, *.89u, *.v2u, *.9xu, *.tib

TI83 Plus, TI83 Plus SE, TI84 Plus and TI84 Plus SE:

 *.rom, *.8Xu

TI83:

 *.rom

Firmware updates (*.89u, 9xu, *.v2u, *.8Xu) which are normally used to restore the operating system of your calculator can also be used as a ROM image.

Needless to say, you will be very disappointed if you purchase Graph89 without having the ROM file ready. You will just see some instructions and a blank screen.

-------------------

Graph89 needs permission to look at your Android Account in order to generate a unique ID shown under F1/About. This works only for TI89/V200. Note that there is no internet connection required for this App.

TiEmu, TilEm and Graph89 have been developed independently of Texas Instruments and are not affiliated with TI.

*请在下载应用程序之前，记得阅读下面的ROM部分！

到计算器的精确副本，它会变成你的手机或平板电脑。仿真器将提供相同的功能，并为您的真实计算器产生相同的结果。被移植到Android，意味着它总是会适合你的口袋里，有一个背光，充电，也跑得更快。

您将能够安装应用程序的APP文件复制到您的手机的内部存储器，按“后退”按钮，并选择“安装应用程序/发送文件”。

Graph89将是伟大的工具，在高中，大学及以后的数学，科学和工程课程。这些计算器设有计算机代数系统（CAS），其具有的能力，以简化和符号解决数学表达式。

Graph89结合了两个功能强大的仿真引擎，这使得它唯一的应用程序在Android游戏商店，支持全系列的TI图形​​计算器。

1）的帖木 -http://lpg.ticalc.org/prj_tiemu提供支持摩托罗拉68K系列：TI89，TI89钛合金，TI92此外，航程200

2）TilEm  -http://lpg.ticalc.org/prj_tilem提供支持的Z80系列：TI 83，TI 83 +，TI 83 + SE，TI 84 +，TI 84 + SE

！重要！

ROM：

模拟器是计算机软件模拟特定的硬件。为了做任何有用的模拟器，它需要一些软件来运行。版权由TI的软件运行在你的计算器（ROM），因为如此，它不能被分发Graph89或任何其他模拟器这一事实。

这意味着，你一定要提供自己的ROM文件提取它从你自己的小算盘。转入到您的手机，然后告诉Graph89哪里可以找到它。要提取ROM，您可以按照指示从http://www.ticalc.org/programming/emulators/romdump.html使用TiLPII从http://sourceforge.net/projects/tilp/files谷歌和YouTube的也伟大的来源的教程和帮助。

也Wabbitemuhttp://wabbit.codeplex.com/提取的ROM从TI83/TI84中一个伟大的工具

支持的ROM文件：

TI89，TI92，TI89钛Plus和航程200：

 * ROM，* .89ü，*。v2u，* .9许，*。TIB

TI84 TI83 TI83此外，加上SE Plus和TI84 Plus SE应用：

 * ROM，* .8许

TI83：

 * ROM

（* .89 U，9xu，*。v2u的* .8徐）通常是用来恢复的操作系统计算器的固件更新也可以用来作为一个ROM映像。

不用说，你一定会很失望，如果你的ROM文件准备，无需购买Graph89。你只会看到一些指令和一个空白的屏幕。

-------------------

图Graph89需要的许可来看看你的Andr​​oid帐户，以生成一个唯一的ID下显示F1/About。这仅适用TI89/V200。请注意，有没有这个应用程序所需的互联网连接。
