I currently have a regular TI-83+, and I know TI-Basic pretty well, but I was wondering if it would be worth it to upgrade to the TI-89 Titanium. I know it's faster, has more memory, and has a higher-resolution screen, but I was looking through the free online manual on TI's website, and noticed in the programming section that it is noticeably different than the TI-83+. So, I was wondering if anyone could provide an opinion or advice on it and whether or not it would be worth it to upgrade. Things such as, is the programming harder or easier, are there more and better programming features, ect.
Thanks for any advice, opinions, comments. |

| You can program in C and there are pretty good libraries. I don't know why you'd upgrade for solely programming reasons. The math capabilities are what you're looking for. The Basic is also "improved" i guess. |

Yes, like Liazon said, with TigCC you can program the Ti 89 in C programing launguage that runs at almost assembly speed, wich is faster than asm on a ti83+ (i think)
the basic programing imo is harder and not worth it as much. if you want to program the 89 you want to do it with TigCC.
the 89 is the best math calculator and is banned on many major tests like the act. It has so many powerful functions liek a solver, pretty print, radical simplifier, factor, expand, to much to list. I would recomend anyone with teh extra money to get one, if not for programing, for school.
I bought it to program with, i havnt made a single program for it yet, but i do have it full of other's games. |

The 89 manages to feel a lot more like a computer than the 83+:
- 89 basic offers way more control over the system.
- You don't have to use menus to get to all the commands (you can simply type them in).
- It actually has a GUI.
- It has a higher resolution.
- It allows custom named variables and functions.
- It actually has a convert-to-string command.
- The memory feels limitless when compared to the 83+ (Our World and Geometer's Sketchpad on the same calculator!).
- The CAS is powerful enough to take an algebra course for you.
- It has Pretty Print.
On the other hand, it has a smaller userbase, though there are still plenty of good programs for it. |

| Would you say that using C on the 89 is better than using Asm on the 83/84 line of calculators? |

ummm
i have made 2 succesful asm programs for the 83+, "hello world" and one that displayed inverted text.
i have made one c program for the 89, it did the same, so i cant say i have much experience, but i would think C is defiantly easier to learn than asm.
the 89 is also faster, more memory, beter file save sytem(folders) soooo many more features, bigger screen resolution(pixel #) etc...
89 is defiatly teh best programing calculator that i have ever seen. (the voyage and 92 im not sure about)
89 is defiantly worth having, i recoomend it to everyone taking algebra (i will pass algebra and algebra 2 class FOR YOU.) pluss teh games are so much better  |

I know the TI-89 Titanium sports a grayscale screen. Does anyone know how many shades of gray is can display?

you can have grey scale on an 83+ (example: Desolate comes to mind)
grey scale is a side effect, not a built in function, and is only capable using asm code for both the 83+ and 89. so you must know asm or C(using TigCC for teh 89) to make grey scale programs. |

| Umm, greyscale is a product of switching pixels on and off at a certain frequency, that is basically it... |

No, a lot of 89 games will still require custom ASM code integrated into the C code to make it run faster. Of course, you don't have to know 68k ASM to use it, you just need to know its inputs and outputs. For example, the new F-Zero game for 68k uses the Mode7 engine, which in its speed critical sections, are written in purely ASM. For small systems like Ti-Calcs, the only advantage that ASM has over C or Basic is more control. With a computer, asking another computer to compile for you is much better considering how more complex a computer processor can be.

You can program for all three 68k calcs using TIGCC at the same time. A lot of its preprocessor/precompile abilities are pretty good. Using Macros, defines, and pseudo constants, you can program for all three. Also, all three use the exact same screen memory. That is to say, although the 89 has a smaller screen, the memory allocated to buffer the screen is the exact same size as the V200/Ti-92 screen, and it is indexed the same way. Code is easily modified for all the calcs.
@plaque: You don't need an 89 for Algebra2, a regular 83+ does the trick. You'll definitely appreciate the 89 for its calculus capabilities.

Standard libraries support only 4 levels of greyscale. Trust me, just 4 levels sometimes looks horrible on a real calc. I believe 7 levels are possible if you write C routines yourself, but it will probably be slower.
@plaque: you're right and wrong about the 68k greyscale. It is sorta "built in" in the original 89 that uses HW1. It's "built in" in the sense that you can trick the LCD driver to accept a different buffer from the hardware buffer to display to the screen. In other words, you can tell the calc every second or so to switch the source of your screen display. In the later HW versions, TIGCC had to modify this method because you could no longer do this. The LCD Driver is now in its own protected section of RAM, so greyscale must be acheived by copying entire buffers (700+ bytes) to other buffers.
For the most part though, grayscale functionality is built into TIGCC. You can use it without knowing how it works where as on the 8x+ series, you will need to know about interrupts and how to write one to perform greyscale.

yeah, its a side effect (or is imo)

yes and no. it isnt needed in algebra 1 or 2, but it would pass the class for you. Im 3/4 of the way done with pre calculus, and i havnt used the 89 but for one section on long division. i dont even cary it to class anymore. |

I can sum the 89Ti up in one word: Superb.
However, you'll need some utilities if you want to play 89 C/Asm games on it, because of the hardware difference. Just look at my sig, I learned it the hard way...
But it has been extremely helpful in math. I still had an A in algebra 1, but the calc is like insurance if you're unsure of something, it will solve a lot of your problems (pun intended). |

89 GS is very possible easily, it has an xorpic command! (BASIC)

bukwirm mentioned that he used cycle pic to create basic greyscale.
basic greyscale will never cease to amaze me

| XORing 2 small pictures works a lot better. (The smaller the pictures are, the faster it works.) |
