Requirements: 2.2 and up
Overview:
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, it will always
have a backlight, be always rechargeable and also run faster.
You
would be able 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)
which have 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.
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:
For TI89, TI89 Titanium, TI92 Plus and Voyage 200 - Graph89 supports: *.rom, *.89u, *.v2u, *.9xu, *.tib
For TI83 Plus, TI83 Plus SE, TI84 Plus and TI84 Plus SE - *.rom, *.8Xu
For 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.
