Conversion of calculator programs from BASIC to asm

I'm looking for someone to make a math program for me for Texas Instruments calculators. The program would have to be made in z80 asm (there is very good documentation from Ti, and it is calculator programming and mostly simple math so I'm assuming it won't be extremely difficult to learn). The program would be created and compiled using Ti's software development kit located at: [url removed, login to view]

I'd actually need 2 different programs - one for the Ti-83 plus/84 plus calculators, and one for the Ti-89 calculator. The bulk of the programs would be a conversion of about 9 different types of math programs that I have already made in BASIC for those calculators (almost all are very simple math) - but I would also like a few new programs to be made that I will specify (which too will be based off of current programs made in BASIC). The programs would mostly be math focused, with a few involving simple geometric graphics, and would be to help answer SAT questions. These programs would have to be extremely stable, as an error could crash the calculator at a critical moment.

I would also need a password system for the programs. This password should only have to be entered the first time the programs are loaded onto the calculator, and should be generated based on the calculator's serial number. This way the user can give me the serial number of their calculator and I can automate what their password will be based on the serial. The idea is to keep users from transferring the programs to different calculators (it should check the previously entered password against the calculator's serial number when started so that you can't enter your correct serial and then transfer the programs to another calculator, but it should only prompt the user for the password the first time it is run).

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):

a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).

4) The programs plus a 2nd file created with the password system removed and the functionality of the program removed besides a sub program or two, and when any of the non-functioning programs are run it would display our website address.

## Platform

The programs will run on all Ti 83/84 plus/84 plus silver calculators, and ti-89/ti-89 titanium calculators.
