I own a TI-83 Plus graphing calculator, and I love to create programs for it. Right now I have from Math Formula programs to Video Games. This is the list of programs that you can download for free for your calculator. Click on the name to download.
If you download something, it would be great if you could email me at Octogator to let me know.
You must have a TI-Graph Link to put these files on your calculator. If you don't have one, you can purchase one from Texas Instruments' Online Store.
| Name | Description | Size (bytes) |
| CHASE.. (V2.4) | This is a video game. You are a person and the snake will chase you. Test out your strategic skill as you try to escape the snake. | 2340 |
| CHASE2P (V1.0) | This is the 2-player version of Chase. It requires a link and two calculators. | 1567 |
| CATCH (V2.1) | This is another video game. you are a person and a ball will be dropped from the top of the screen. You must try to catch it using the arrow keys. (It is similar to pong.) | 1134 |
| GLOBS (V3.1) | This is also a video game. In this game, you must make up equations to try to intersect randomly placed circles on the graph. | 2848 |
| BATLSHIP (V2.1) | This too, is a video game. This game is battle ship for one player. You must guess coordinates to try to hit random ships. | 2118 |
| LASER (V1.0) | This is a video game. You are X and you shoot lasers to catch specific things. | 1358 |
| ZOOM (V1.0) | This is a video game. You need to get certain things without hitting the star. | 1009 |
| AREA | This program can determine the area of a square, rectangle, circle, triangle, equilateral triangle,parallelogram, rhombus, trapezoid, and any polygon. | 1072 |
| DETRMNT3 | This program can do a 3 x 3 determinant. | 491 |
| DRT | This allows for you to solve for any one variable in the d = rt formula. | 548 |
| FNDSLOPE | This program can determine the slope of a line by using two points on the line. | 518 |
| FNDYINTR | This program can find the y-intercept using a point on the line and the slope. | 461 |
| SLOPE | This program will graph one or two lines on your calculator when you enter the slope and y-intercept. (Hint: If you want to download one of these programs, download all of them: FNDSLOPE, FNDYINTR, and SLOPE.) | 590 |
| INTRCEPT | This program finds the X, Y and Z intercepts when graphing a plane in 3-space. | 468 |
| AVERAGE | This finds the average of a set of numbers. | 441 |
| FOIL | This program foils (multiplies) two binomials. | 411 |
| PARABLAA | This program works with parabolas. It can find "A" in the parabola equation, find the vertex of a parabola from its equation, find the axis of symmetry, and graph it on the calculator. | 642 |
| CONICS | This program does everything for conics. It does the distance formula, midpoint formula, parabolas, circles, ellipses, and hyperbolas. | 2132 |
| DEGREES | This program converts fahrenheit to celsius and celsius to fahrenheit. | 475 |
| LOG | This program can solve the log with any base of any number. | 422 |
| SINCOS | This program will give you the (x,y) coordinate of any point on a circle when you tell it the radian or degree of the angle. | 554 |
| ARCS | This program can find the length of an arc and solve for angle and arc measures. | 995 |
| GEOMEAN | This program can find the geometric mean between two numbers, ans a number when given the geometric mean. | 597 |
| POLYGON | This program determines the number of sides of a polygon when given a specific interior or exterior angle, and vice versa. | 739 |
| TRIGLAWS | This program does the law of sines and cosines when solving for either a side or an angle. | 1042 |
If you want a program that can do something else, I would be glad to take a shot at it and put it on my website for downloading. Contact me at Octogator.
Go to my dad's site: Barbor Software. It is a site with some cool sports CD-ROM games and more for the PC that he has made. It also contains cool links like joke of the day and much more!
