The best solution is probably to realize that you don't need it. If you follow the recommendations in this document, virtually every program can be run even if your version is as new as 2. If you really must have an older verison, it may not entirely easy to get it. The older versions were once distributed freely on TI's web site when they were new but they only supply the most recent version so older ones are no longer available. Many web sites have offered older versions for download, but TI does not approve of this and has threatened some of those sites with legal action, resulting in most of them being shut down or removing the ROMs.
One way to obtain an older AMS is to get it from another calculator. If you have access to another calculator that has the older AMS version, you can transfer it between calculators through the calculator-to-calculator link. You also can reportedly get these from TI through E-Mail by request. To do this, send E-Mail to ti-cares ti. You should get it within a few days. Note that the file will be over a megabyte in size, so be sure you are able to receive large e-mail attachments.
The current version will run most games but it has very limited math capabilities. HW stands for hardware, which means that it is the version of the hardware. To change this, you would need to replace the internal circuitry of the calculator. This problem was fixed a while ago, but there are still some programs out there distributed with older launchers. This is usually the case for launchers that are bytes on the calculator and bytes in files on the computer or very close to this.
There are several ways to fix this:. There is one program, Propanoid68K, which has this problem and can't be fixed by these methods. However, it can be fixed by running Ghostbuster on it, which seems to work even for a regular TI Probably not. You just need to replace the batteries. If the calculator turns off whenever doing anything that uses the CPU continously like a calculation that takes a significant amount of time, or playing a game then low battery power is almost certainly the cause.
If you have run a program which has locked up, you may be able to use 'escape' mechanisms of various kernels if you have them installed or nostub launching utilities if you used one. If that doesn't exit the program or you have another kind of crash, like seeing a black bar across the top of the screen then you will have to try to reset the calculator. If this does not work, you should then try removing all batteries including the lithium backup battery from the calculator to completely clear the memory.
Using either one of these methods should still preserve archive memory, as described in the next section. You should always report crashes in a program to the author of the program, as described in the bug reporting section of the FAQ.
It is possible to protect files from accidental crashes in almost all cases. To do this, you must store the files in archive memory, and use AMS version 2. Then, the archive memory will be preserved after the calculator is reset. There is also a program called Archive Utility which can allow you to preserve the archive under older versions, but it is not compatible with all calculators and there is now little reason to avoid newer AMS versions.
There is also 'crash protection' provided by kernels that may allow you to recover from crashes, and some programs have built-in crash protection also. These may work, but you should not rely on them to protect files in RAM. Source Guru is a program that I wrote, intended to demonstrate the possibility of automatically converting programs for the TI to run on the based calclators. It did succeed in that purpose, as it made working conversions of several programs. But they are not really intended for general use, and they are probably not as good as the TI equivalents.
They also might have some compatibility problems. GTC is a flash app that enables development on the calculator on C or assembly language. This is a fairly complete assembler, though you should of course read its instructions to learn about its specific limitations. It also requires a kernel.
Keep in mind that your own programs, when first tested, are much more likely to crash than any programs you get from others, which have already been through initial testing. For this reason, be sure to protect all of your important data including the kernel, the assembler, and the source code as described in the data protection section. Unfortunately, the hardware design HW2 originally caused some difficulties for using grayscale with it especially since it wasn't documented.
However, these problems have been solved long ago and HW2 calculators can now display relatively steady grayscale in 4 colors just like HW1 calculators can. For grayscale programs using the gray4lib or graphlib libraries, use an updated kernel, and grayscale should work without any problems.
Since these have the grayscale code built-in, you can't use the new, better grayscale just by replacing external libraries. This problem can now be fixed, as a new version of TIGCCLIB including the better method of displaying grayscale has been available for quite some time.
However, programs will need to be recompiled with the new library to take advantage of it, so you may need to wait for new versions to be released of course, if the program is supplied with source code, you could always recompile it yourself instead of waiting for someone else to release an updated version. Most programs except huge math and utility programs from TI's web site are not flash applications, and thus are not normally given these extenstions.
If you have this problem, you are probably trying to use the command of the Graph-Link software that sends flash applications. Since the program you want to use is a. In general, it is probably a good idea to keep all programs in archive memory, and use RAM just for temporary storage e. RAM is likely to be erased if a program crashes, and you may need to reset it if a program malfunctions in a way that disrupts the calculator's operation.
However, files in archive are much more protected, so they can survive if the calculator crashes. Note that it is not necessary to use these types for a program's data; many games store their external level files and such inside regular data types, often in strings.
If a program is distributed with. The "ppg" file type on the calculator is normally used for exepacked programs. They are essentially nostub programs in compressed format devleoped by the TI-Chess Team. Such programs are normally supplied with a small launcher in the form of a regular program which will decompress and run the launcher program.
The launcher also circumvents the size limits under some AMS versions so you don't need to worry about them when running such a program. If you are using TICT-Explorer or Explorer by Flavien Racine as your shell, then you don't need the launchers since that shell has support for running such programs included in it. Note that some older launchers are incompatible with AMS 2. If you find one of them, look at the "invalid relocation" question above.
In general, a Voyage calculator can run the same programs as a regular TI Plus. However, beware of the following compatibility problems:. However, recent programs may be compatible already, especially if released after the middle of or so.
In addition to patching, special tools must be installed for TSRs or kernel-based programs to work. This is especially true for games but other types of programs also are likely to have problems. In most cases it should be fairly easy for programmers to their fix programs to work on the TI Titanium, but this has not yet been done for some programs.
Fortunately, a set of programs has been released that will enable TI programs to run on the Titanium. Here is a summary of the tools and when they are needed to be able to run every program, you should use all of these :.
Note that, as stated in the previous section, most of these compatibility problems can now be overcome. The compatibility issues depend on the program type, as follows:. Therefore, if a C program was released earlier than this, it will probably fail. However, some C programmers have compiled new programs with older versions of the compiler especially since ticalc. Additionally, programs made with newer libraries still could fail if the program itself does something incompatible.
Programs made for much older library versions might need some changes to their source code to work with the new library. If there is incompatible code in the program itself rather than just in the library routines used that will also require the source to be changed, but such cases will probably be rare.
Ghostbuster should be able to fix all such problems stemming from TI-GCC library routines, and many of the problems from other sources as well. Nostub programs in assembly language are likely to work if they don't use grayscale or try to install TSRs. However, more complex nostub programs and some simpler ones as well will not work until they are updated for the TI Titanium.
This generally requires changes to the source code. If your screen does not match the one shown, press d until it does. Type the number whose arctan you want to find. How long your batteries last depends on how much you use your calculator. The four AAA bat- teries in the calculator usually last for about a year with normal use in a calculus course. The backup battery can last anywhere from 2 to 5 years. Try removing all main batteries as well as the backup battery — and leave it this way for at least 15 minutes more if you want to be on the safe side.
I had my TI lock up once to where waiting, not just pulling all the batteries, was necessary. I hope this helps.
