Boolean Brain
By W. K. Balthrop
By some freakish accident, you have been sucked into your computer while playing a game and now you have to find a way out by navigating the different sections of the computer and try to get to the CPU in the hope of fixing the problem. Unfortunately, moving from one section to the other requires solving boolean puzzles using AND and OR gates. Each section is represented by a door, and you can chose your direction of travel by typing E,W,N or S. Solve the boolean puzzles by activating one on more input lines in order to turn on the output. Beware of fatal bad disk sectors however! This is an excellent exercise in boolean logic presented in a very original way.

SkyChart
By Walid Maalouli
SkyChart is a 100% assembly astronomy program that can calculate and display the position of the planets, about 375 stars and all Messier objects for any date and time from year 0 to 9999 AD. Constellation lines can be toggled off and on, and information can be requested on any object displayed. Accuracy is only limited by the TI screen resolution. For those with an interest in astronomy.
Requirements: E/A cartridge, 32K RAM, disk drive.
Executable to run: SKY (E/A option 3 - read instructions for startup procedure)

Pi Calculator
By Walid Maalouli
If you have ever had the urge to calculate many decimals of Pi, then this program is for you. Originally written in XB, it can calculate up to 5200 decimals of Pi. The limitation is really available memory as well as time as it can take several hours to extract a large number of decimals. The result can be displayed on screen, saved in a file, or printed. Fred Kaal converted the program to c99, resulting in much faster calculations but limited to 2600 decimals due to limitations of c99.
Requirements: XB or E/A cartridge, 32K RAM, tape or disk drive. Printer optional.
Executable to run: PICALCXB (XB version) or PICALC (c99 version - E/A option 5)

Game of Life
By Mark Wills
Few games are more venerable than this one yet its appeal remains timeless. This is essentially a simulation of the life cycle of cellular automata where your screen represents the world. You place single cells in the world then watch them reproduce and die, creating in the process some fascinating patterns that seem to have a life of their own. Some end up in stable patterns while others migrate around and affect the lives of surrounding cells. This version of Life is very well done and fast, with features such as a screen editor as well as a wrap-around world. An instant classic.
Requirements: Editor/Assembler cartridge, 32K RAM, disk drive.
Executable to run: LIFE (E/A option 5)

SimRocket
By Walid Maalouli
For the model rocketeers among you, this program is a model rocket flight simulator which takes into account the rocket's basic specifications, motor, as well as drag, wind speed, launch rod angle and recovery type. Flight data can be viewed in 2D animation, saved to disk or printed. This is a great tool to test different rocket and launch configurations without risking the real thing, but can also be fun to play with even if you don't fly rockets.
Requirements: XB cartridge, 32K RAM, disk drive.
Executable to run: SIMROCKET
