ASM z80 Machine Lang Project

Project will require the ASM/Z80 programmer to code for the TI-83 Plus calculator. This project is not a game, nor is this project an application. The project is a secruity suite.

The ASM/Z80 programmer will code 3 security scripts for TI-83 plus using: [url removed, login to view]

Program #1

1) Extract the serial id from the calculators certification FLASH ROM memory segment. Each calculator has 16bytes of address space containing such information.

E-mail me if you have questions on this stage.

Program #2

1) Encrypt the serial id using a 256-bit key.

2) Store the encrypted serial back on the calculator to a secret memory address location.

E-mail me if you have questions on this stage.

Program #3

1) This program will launch only if the calculators serial id matches the one that was installed by Program #2.

2) This program will launch ONLY if the calculator is a TI-83 Plus.. which means the program must fail if the device has been loaded on a TI-83, 84, or 89. You can check the certification memory segment for related information.

E-mail me if you have questions on this stage.

The above three programs will ensure un authorized copying of program #3 cannot occur. Also, program #3 may be layered into our proprietary software which was coded in TI-83's basic like language.
