Upcoming encryption program
Jonathan Blair  Account Info

I have just submitted an update to my Pictoral Encryption program (Pictoral Encryption/Decryption v1.5) which now is fully functional (encrypts and decrypts). The programs utilize a complex algorithm (so complex that it could be said that it is in the class of computer code), though it is written in TI-89 BASIC. These programs are definitely something you should check out if you use an emulator on a computer in addition to your calc. As long as you have the time, the programs will conveniently convert any message (mainly supported up to 114 characters) into a picture and allow you to save it under a new variable and take the saved picture and revert it into the original message. If you're interested about how the gory details of this program work or would like to know how to go about customizing the algorithm in the programs, feel free to e-mail me. Note: these programs are large (around 18k each on the calc) and take quite a bit of time on the calc (approximated at 70 min. for a medium-sized message of 37 characters), but this varies and may change because I am thinking of implementing an optimization in the encryption program shortly which could decrease processing time by 1/4 or maybe more. Remember, the reason this takes so long is because the calculator is dealing with very large numbers and long lists (2,000 entries or more). So go check it out!

I am currently writing a basic program that can make a pogram impossible to use unless there is a password for it.

password for programs
Musiconwheels06 Account Info

I made a system for the 86 that was essentially a basic program that was required to be run in order to run the other programs. A block of code was pasted at the beginning of all other programs (basic), and then the programs were locked to prevent editing. I did it with weird variables that stored numbers like e^pi +3. If that number wasn't stored in a variable, the programs couldn't run. The trick is that the variable holds 14 placese, but the screen showed 12, so there was no way to guess what they were. I lost the programs though, becasue the calc crashed and I didn't have a backup. Let me know if you need help.

I am currently writing a 'shell' for the 89 in TI-BASIC. Why not do it in ASM or C? I'm learning both, but writing a BASIC shell seems more impressive than writing one in ASM or C.
After about 1/2 hour of work, it has the following features:
1. Up to seven 'folders'
2. Up to seven programs in each 'folder'
3. Program deletion (from the calculator)
4. Ability to add programs sans programming
5. Ability to remove programs from groups w/o deleting them entirely
6. Fairly decent interface, with 'folder' expansion, scrolling '>' mark, etc.
7. Can run _nostub ASM programs and BASIC programs

To come:
1. Renaming and moving variables
2. Auto-detect folders and variables (which will probably require C)
3. Scrolling lists of groups/programs
4. Run functions (automatically find # of arguments)
5. Rewrite in ASM or C

Re: BASIC Shell
Bastien JANSEN  Account Info

There already exists a good shell for TI89 written in C called lin4ti. It's a linux-like shell I wrote, and I should add more commands, but I have no good idea now... If you want to look at the source code...

Thats not a shell...
Darwin695  Account Info

Ok, a shell is basically the same thing as a kernel for calculators... it is an asm library of functions (like a .dll file...) and some other functoinality. MirageOS (for the 83) does more than just show your programs to you...
What you are doing is called a file explorer like the more popular TICTexplorer (TICT = the TI chess team...if im not mistaken).
While i applaud your efforts... i am on a never ending crusade to keep the programming vernacular pure...

Rigview for the TI-89?
dabud15 Account Info

I have both an 83+ and an 89Titanium. I really like the program Rigview for the 83+, which allows me to view any photograph I want on the calculator. I was wondering if there existed such a program for the TI-89, TI-92, or TI-89Titanium. If so, then what is the name of it and where can I get it?

Thanks in advance,

Chat Program

I've been considering for a short while about making (or requesting ;) ) a chat program that communicates via radio waves or some other wireless communication method. Unfortunately, I lack the time, technical knowledge, programming knowledge, and equipment to attempt this myself, which is why I'm posting it here. Please reply quickly!

Java compiler
x04ty29er  Account Info

I am currently working on a java compiler for the ti89. all i have done right now is System.out.print() and System.in.read(). I intend to alter the java coding a tiny bit to make it easier to use. if you want to help (or just want to give me ideas) i would greatly appreciate it.(its written entirely in BASIC, so if you would like me to make it in C or assembly, tell me and i will switch to C/assembly(but i will need some help in this case).

Linux on the TI-89 Titanium
Mr.Z  Account Info
(Web Page)

I have begun work on porting Linux (uClinux with kernel 2.6) to the TI-89 Titanium. It should be relatively easy to port it to the V200 (& maybe TI-89/92+ if it is small enough) from there later.

USB support (both as host & device ("gadget" in the kernel options))
TI keyboard support (almost necessary on the TI-89Ti)
Treat the link port as a standard serial port (plus DBUS raw mode & maybe I2C mode)
(maybe) support for being installed as an app (dependent upon size & difficulty)

Re: Upcoming TI-89 Miscellaneous Programs

I have a program in mind (ASM) that would allow you to send programs and maybe other types of data to other calculators. If you assigned a hex number to every character (a-z, A-Z, 0-9, + , -, *, /, and greek symbols) on the calculator, then transformed a program imto this hex code, sent it over a link onto another's calculator, and had his program identical to mine (made for the type of calculator he or she has) translate the code back into charcters and pasted it into a program of the same name as the original program. It would be done this way rather than translating a program into another calcs way of reading it so that I wouldn't have to make 42 different programs, only 7. I just need help as I am not affluent in Z80 ASM, and can't even contemplate 68000 ASM. I do not expect to be able to run 86 programs on an 83, just so that I can make 83 programs for friends and use my 86 to pass them on.

That would be pretty cool! Maybe have it convert compiled basic programs at least somewhat so editing neccesary is minimal?

Re: Re: Upcoming TI-89 Miscellaneous Programs
Nick Jones  Account Info

I have been working along that idea... I made a set of programs (z80 and 68k) in assembly to transfer raw data between TI calcs... Though a link algo I designed. The code is not calc specific, so it CAN work with any of TI's calcs...

The only problem I've hit is that I can't disable (can't find) the autointerupt that calls the linkport's auto-connection code on 86/89/92+ calcs... This effectively stops any data from being transfered until the code stops... If I could find out where the systemflag to disable it is, I could finish, debug, and release it. I've been working on finding the sysflag, but it isn't much fun... Emulators don't do raw wire control too well...

sorry to be negative about it, but this is the most obvious way to transfer files between different platforms. this is not a new idea at all.

great idea
eric canton  Account Info

this sounds like a great idea! I have an 89 and 83+, oh yeah, real compatible[not].
I'll be interested, and if you can pull it off, send a copy to me, and I'll add it to ULTIMATE OS, on a later version of couse. Please no program souce codes, especially in other laguages than C, my main language.
I just dont have time to sit down and copy code, and especially translate, between school work and ULTIMATE OS debugging, plus the zillion other projects I'm working on.
If you, or anyone, would like to be part of pi_delta_pi, e-mail me at: pi17ultimate@incamail.com.
Notice: you must have programming knowledge in either ASM(help needed badly), C, or BASIC.

Re: great idea

Someone already has a program for the 89 that allows you to store in memmory programs for other calcs. You can then send them. It's helpful if you want to store an 86 file on your 89. Look it up in the archives.

I was working on just such a program. It is called UniLink, & it is indeed in the archives (perhaps to what you were referring). I am no longer much interested in it (I want it, but too many other things need be done first), so if anyone wants to continue it (say, writing routines to link with more calculators), feel free to contact me.
