## Graph 89 - (with TI84 support)

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_tiemu providing support for the Motorola 68K family: TI89, TI89 Titanium, TI92 Plus, Voyage 200

2) TilEm - http://lpg.ticalc.org/prj_tilem providing 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 from http://www.ticalc.org/programming/emulators/romdump.html and by using TiLPII from http://sourceforge.net/projects/tilp/files Google and youtube are also great sources of tutorials and help.

Wabbitemu http://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.

Texas Instruments and TI are trademarks of Texas Instruments Incorporated.

Morphological binary image operations are a collection of operations designed to enhance the structures within the binary image based on some structuring elements. Good descriptions of these operations can be seen in, http://en.wikipedia.org/wiki/Mathematical_morphology. This app has been developed to demonstrate the working of the following morphological operations: - Erode, Dilate, Opening, Closing, HitMiss, Prune, Thin, Thick, Skeleton, Boundary and ConvexHull.

The operations presented in this app have been developed based on descriptions provided in "Digital Image Processing (2nd Edition)" by "Rafael C. Gonzalez & Richard E. Woods". The structuring elements are 3X3 matrices.

The app uses 50X50 pixel sample images to run the operations on. The images can be selected by clicking the image icons. The images are then expanded so that their pixels can be clearly seen.

Using the spinner, an operation can be selected to run. The operations though instantaneous, have been deliberately slowed to show intermediate results for the user to appreciate and learn these operations. While an operation is running the processing icon is displayed. Users can run operations any number of times as desired. To change the image or to reload, simply click the image icon.
