Great program, no instructions I am not talking instructions for using the TI-59, but instictions like installing modules, creating mag cards etc. A site for help and hints on using the App.

Love this but... I love this calculator and sincerely appreciate the effort that went in to it. It brings back lots of memories! This last update though doesn't fill my nexus 7 screen like the previous version did. I hope we can get that back. Thanks!

Nice Emulator. Very faithful to the original! Lawrence, if you're open to some simple suggestions, then consider breaking "true" emulation and make small concessions to the display. Back in the 70's the LED display technology was a huge limitation and some things that really should have been displayed were omitted. (1) A small status line to display things such as the current "2nd" and "INV" state, as well "Deg/Rad/Grad" would be incredibly useful. (2) In program mode a simple 3 character mnemonic (like "log" or "SUM" etc) could be appended to the numerical op-codes. This would greatly simplify program editing. Some purists might object to any departure from the original display, but it could be as an option.

Coolest app ever. This is NOT my favorite calculator. It IS my favorite app. (It's my 2nd favorite calc.) For a good calculator, and to answer everyone's reservations about this, get the "RealCalc" app. It does what you want. But THIS app, does even more. It's an almost perfect emulation of the Ti-58 programmable calculator. And that's what makes it so special. I can't believe how much work the author put into recreating this wondrous old machine. Here's my deal . . . I have to level some sophisticated avionics systems. I have an ultra-sensitive electronic level that reads out in tenths of a milliradian. I have to insert a shim that corrects for that deviation. So, I have a right-angle triangle with an adjacent of several inches, and an opposite of maybe .0005". Try plugging those numbers into any "triangle" app. Those apps are made for "high-school" shop class trigonomics. This app solved my problem. With a few simple "learning" key strokes, I entered a somewhat complex formula, and could convert a number that was tenths of a milliradian, directly to an appropriate shim size, with one "virtual button". The possibilities are infinite. I could write a book on how cool this app is. Perhaps I did.

Why not full screen? On my 7" Samsung tablet running 4.4, I'm getting a small image of the keyboard in the center of the screen with a large black border area all around. This app would be much easier to see and use if it was expanded to a full screen image.

I have put a link to the GitHub source repo in the store description, and it’s also in the about text in the app. There you will find tools for assembling programs from symbolic form and creating loadable program/library files. It's ok It's really good but how do I get to the integral and differential buttons? It's screen is small I expected to see a large screen to see steps to the answers too.

Lawrence D’Oliveiro March 28, 2014

Calculators in the 1970s didn’t have those functions. My Old Friend My TI58c got me through high school, trade school and college but it stopped working some years ago. I missed its simple but powerful programming and was pleasantly surprised to find this app. It's a really good recreation with modern conveniences. I use it every day. Good job and thank you!

nearly perfect! I love this calculator! It reminds me when I was a student (my math teacher had a ti58c, I couldn't afford it!). I'm wondering if also the other libraries will be implemented/completed sooner or later or not. PS: in the meantime I tried to add some modules to the orignal library, I started with ML-02 (DETERMINANT, MATRIx. & SIMUL EQ) as I found the source code. Unluckily the emulator could have a bug as it doesn't work.

Hmm Needs work. First thing I do on any calc is test divide by 0. Fail here, no error msg, just 0. Clicking key sounds are obnoxious and no apparent way to silence. On Nexus 7, app grabs whole screen and only uses 50%. At least make it float. All that in one minute test. There is promise here, but not ready for prime time. I'm shooting for the moon, not cosmic debris.

Great also. I still have my ti59 and the printer. The print head no longer works but it makes a good desk unit. I also have most of the ti59 newsletters (with all of tips and tricks). If you would like a copy of them let me know.

reminds me of my first TI-30 back in about 1979 03AUG2013 I love this APP. Reminds me of my first TI-30 which I think I got in High School around 1979. Doc Claridge (R.I.P.) our science teacher for two years, Physical Science and Chemistry, would not allow us to use calculators in class. We used slide rulers to calculate outputs of chemical reactions using quadratic equations as I recall.

Wonderful Loving this latest update to an already awesome calc. Easier to hit/see the buttons now.

Lawrence D’Oliveiro June 27, 2013

Not sure what you mean. Are the buttons unresponsive? A must for every android! If you ever had or used a ti58/59 before, this is a must. Even the faint "C" on the leftmost digit is faithfully implemented. Now with selectable key sound or vibrate or off. I wish there is a way to remove those posts with key sound complaints. This app would get a solid 5! I still own my real ti59. But this is faster and more accurate in calculations (of course). Wonderful, thank you! But wait ... all other modules please! :)

Keys are not responsive I push the keys and get locked out or they don't work at all. Galaxy SII

Excelent calculator Exactly as the original. With all the functionality. Thanks

# What's New

15611.5: increase size of tappable button area to see if that reduces complaints about unresponsive buttons; more consistent layout size on larger vs smaller screens; notification status now appears while program is running in background, not just when it stops; CE in error state now clears error state without clearing display.

15457.0: scale layout on phone-sized screens while centring on tablet-sized screens.

## Wabbitemu

Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Wabbitemu supports the TI-73, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, and TI-86. Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing.

Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.

Frequently Asked Questions:

1. How do I bring up the menu?

You can bring up the menu by swiping from the left edge of the screen, or pressing the menu key (if your device has one).

2. How do I disable vibration when I tap on a button?

Open the menu and click on settings. Under the 'Skin' category unselect 'Vibrate on keypress'

3. How do I load apps like PlySmlt2 or Inequalz?

To load any file to your calculator you need to first download it to your SD card or internal storage on your device. You can find the official TI applications for the 84 Plus (non color) available here: http://education.ti.com/en/us/software/search/ti-84-plus-family-ti-83-plus-family#view=math-apps. Once you have downloaded the app to your device open Wabbitemu. Swipe from the left edeg of the screen to bring up the menu, and select 'Load file'. Find the file you just downloaded in the list and select it. The file will be sent to your calculator. Apps for the 83+ and 84+ calcs will end in *.8xk. Apps for the 84+CSE will end in *.8ck or *.8xk.

4. I'm missing fraction options when I press Alpha+F1! How do I get these fraction options?

Fraction options (and the rest of the Alpha+FN menus) are only available on OS 2.55 MP. Wabbitemu allows you to download both 2.43 and 2.55 MP. You can check your OS version by hitting '2nd' then '+'. Then press enter to go to the about screen. If it not 2.55 MP or 2.53 MP you will need to upgrade.

To upgrade you will need to recreate your ROM by going through the setup wizard again. The setup wizard is runnable if you bring up the menu by swiping from the left edge of the screen. Then select 'Re-run setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.

## Andie Graph

Get a TI-82, TI-83, TI-83+, TI-85, AND TI-86 emulator for your phone!

Andie Graph is an Android port of the AlmostTI emulator by Marat Fayzullin - http://fms.komkon.org/

*** ROM not included. Why? http://dgmltn.com/roms ***

The TI-8X series of calculators work great as standalone calculators, showing 8 lines of history, using standard mathematical notation. Each model was designed with more specific purposes in mind:

The TI-82 is designed for algebra and trigonometry. Graph and compare functions, perform variable substitution, and solve single variable equations.

The TI-83 is designed for statistics and trigonometry. Graph and compare functions, and perform data plotting and analysis.

The TI-85 is great for engineering and computer science. Graph and compare functions, perform bit manipulation and convert between numeric bases.

The TI-86 is great for engineering and calculus. Graph and compare functions, perform bit manipulation and convert between numeric bases. Solve differential equations, plot vector fields.

All models allow you to write programs in TI-BASIC and perform basic scientific calculator operations.

## Infinirule Virtual Slide Rule

Infinirule is a virtual slide rule application for Android. It transcends the limitations of real physical slide rules by allowing variable precision--just keep zooming in to get more--and automatically wrapping scales around--like a circular slide rule, but without the bulk. And though it only shows four scales at a time, you can select any combination of the available scale types.

Free Software (GPL).

## Unicode Browser

Browse the Unicode character set, examining characters by category or by similarity; search for names containing specified substrings; save a list of favourites for quick reference. Also copy and paste text between this and other Android applications.

You can display characters for your system font, which is dependent on your Android version, or you can select any .ttf file present in your system installation or on external storage.

Note that unavailable characters may appear as empty boxes, or as nothing at all. If you want to see a wider range of characters, try downloading and selecting the GNU Unifont. This is bitmapped, but should be better than nothing.

## Porter-Duff Browser

Demo of using Porter-Duff transfer modes on a simple pair of sample images. For the rationale behind their definition, see the original 1984 paper by Porter & Duff here http://keithp.com/~keithp/porterduff/
