TI-89, TI-92 Plus and TI-92 Information By Gareth James
Posted by Nick on 29 March 2000, 01:19 GMT

Gareth James has written an extremely informative paper on various information relating to the TI-92, TI-92 Plus, and the TI-89's structures, variables, and some other general information. This should be extremely helpful for anyone developing assembly programs for these calculators.

Now someone go out there and fix AMS v2.03 and HW2 support. ... j/k :)

This is just too nifty. I've been looking for a good source of info for the 92+ for awhile.
Hopefully this will inspire some people to get into 68k asm more, and maybe a hw2 (*crosses fingers*)

Btw, first comment. At least it should be. I loaded this up only about a minute after the article was posted.

Do these people derive all of this information by hand?? Or do they have inside sources? Or are they driven by an inner need to find out every scrap of information about a calculator? No offense, I am just wondering how the heck (or why the heck) everything is looked up. Of course, it is quite useful, but doesn't it take a lot of time?

Check the time in the lower left hand corner of a reply box to find the time it was posted.

yeah, but if you check the time, youll see that it was only a minute after the first one. It takes a few minutes for them to get posted. I refreshed, and then i saw a comment, and it wasnt mine! OH Why!!! :(

im really ok, it doesnt matter that much!

Gareth's files.txt somewhere in the ticalc archive is possibly the single best reference on this site - a full listing of TI's file formats and how data is referenced internally (parsed/tokenized). I haven't looked at this, but it should be very helpful. . .

There's a pub/text/calcinfo/files.txt, but I don't know if that's the one you're talking about.

Yup, that's the one - much better info than anything TI's given us =)

Gareth's informations are good, but they are very briefly. Although he documented much more functions than me, a lot of functions in Gareth's info are just declared, without any explanation. I think that my informations supplied with tigcclib is much more useful if you want info about particular TIOS routine (although, again, Gareth documented much more structures than me).

Btw, I just uploaded tigcclib release 1.5 on ticalc with floating point support and symbolic mathematics support (it will appear soon in the archive). In summary, more than 100 new functions in compare with tigcclib 1.1. And, after reading and understanding all info from Gareth's documentation which are currently unknown to me, I will prepare a new release of tigcclib (maybe 1.7) with a lot of new features too...

I bet we'd all love to see that. We all just love documentation, don't we? Although I did have a big problem with adjusting the path for the most recent tigcc released; caused my 'puter to bomb for some reason. I took the directory of tigcc out of the path and all was well again. Don't ask me why it happened. :-)

The emphasis is more on the layout of the machine, and an explanation of the fundamentals. It is not a programming reference particularly, although I did include macros for the ROM calls. It should not conflict with your (nice) documentation.

I will not have time to work on it for a few months, so thought I would release what I had done. I hope that it is useful for projects such as your own.

In fact, I agree with you. The only problem is in fact that knowledge of TIOS internal routines (e.g. routines which does not have entries in jump table) is irrelevant for me, because I cannot use them. This is not the case with structures: I am very happy about your descriptions of various data structures. I didn't know anything about events, etc. Btw, I am only wander how you discovered names of internal TIOS routines which does not have entries in the jump table???
