View Full Version : AlmostTI85 - Texas Instruments TI85 Emulator
Hello, All!
I have just uploaded the first version of AlmostTI85, my TI85 emulator, to Extras. ATI85 will turn your tablet into a virtually perfect replica of the real TI85, a programmable scientific calculator from Texas Instruments. Beautiful TI85 faceplate artwork has been done by Andrew Zhilin (aka wazd).
You can get ATI85 here:
http://maemo.org/downloads/product/OS2008/ati85/
Please, make sure you vote for it if you like it.
fms,
that looks excellent.
one thing, could you rotate the picture on the product page, its hard to see sideways and we can't just rotate our monitors as easily as our tablets ;)

Nice, but I would really like to see TilEm in a finished form.

It has "All Z80 TI calculators (73, 82, 83, 83+, 83+ SE, 84+, 84+ SE, 85, and 86) except the TI-81," so that would cover the 85 as well as the better 84 series.

How do you make it stop? I am having trouble closing out of the program. Looks fantastic.

That's dependent on me learning enough GTK to fiddle with it, or someone else picking it up. I wasn't intending to learn GTK, but given how useful a properly working version of this would be to me, I may give it a shot, once exams are over. If I do, I would appreciate some help with the skins, though.
For now, though, congrats to fms and wazd for what they've done! I'd try it, but I only have an 83+ ROM.
EDIT: is this an emulator, or a re-implementation?

jaem, it worked out of the box for me. No ROM needed (I only have a 83+ and a 84+). I am guessing it is running a open source OS.

It is an emulator, not a reimplementation.
No ROM needed (I only have a 83+ and a 84+). I am guessing it is running a open source OS.
ATI85 includes /usr/share/ati85/TI85.ROM file into the package. Given that Texas Instruments has long moved from Z80 based platform to the much more advanced 68000 based one, the TI85 firmware is mostly of historical value.
WOW this looks and works just like the real thing.
Only problem: can't get it to quit (using N800 with no keyboard of course) When I try and quit it through the window manager, it seems to get stuck in an infinite loop or something (processor speed at around 50%) Only option left is to kill the process.
Would be great to have a small x on the top left corner of the calculator image and have that mapped to a quit function - or at least let the default shutdown command from the app manager work and not crash the program.
tksu, just press "return" hardware key

To quit it, simply press the ESCAPE key (the one with a little back-arrow). As to the getting stuck problem, I will take a look at it tonight.

Well, TI86 support is coming to ATI85, and Andrew has already created the faceplate image for it. Just need to test if I can boot the firmware. As to other calcs, will look at them as time allows.
I have just uploaded ATI85 1.1 to Extras. This version will also support TI86 calculator.

Well done! Thank you for this, I really missed a good calculator for my N800. And I have a TI80, I love it. I'll love ATI85 as well!
Amazing work as usual fms.
It seems like Ti has taken over the market these days, but is there anyone else out there interested in getting x48 or another HP48 emulator properly running on our NIT's ?
Works well for me.
Thanks

How does the TI86 emulation work? The TI85 comes up, but I don't know how to change it to an 86.

There is a version of x48 running on my n800, which seems to work fine for me. It's at

This is now a MUST have on the NITs, works really well. Thanks!!
I have just a little request, do you think it would be possible to make the calculator close it self when " [2nd] + ON " is clicked? It would make it even more realistic!

Thanks Jay, I have x48 but it's too slow to use. It also needs to be modified to work in landscape mode like AlmostTI85. Anyone willing to take this project on?

There is a separate "ATI86" icon in the menu to start the TI86 mode.

Is there a way to install additional apps on the TI 86 emulator? Textas Instruments still has a large repository of apps on their ftp ( ftp://ftp.ti.com/pub/graph-ti/calc-apps/86/ ) and there are even more apps at http://www.ticalc.org/pub/86/ .
Also I have some apps written on my old TI 86 which I want to upload to the emulator.
On a real TI86 I would use the serial port for this. But what is the serial port equivalent of the TI 86 emulator?
Is there a way to install additional apps on the TI 86 emulator?
Not yet. Coming later.
Ahh, the TI85. In high school I soldered up a dongle that connected the TI85 to a dos computer (I think) in order to load up tetris on my TI85.
Funny thing is, although I've done no hardware tinkering with my n800, my gadget geekdom went entirely dormant until I got my NIT. Now it is alive and well.

Another nice feature would be if the emulator could retain the memory content when closing the application. Like the real TI86 does when switching off the device. Currently e.g. writing programs on the TI86 emulator is a bit pointless as everything is lost after an application restart.

This feature is also coming.
The new ATI85 version 1.2 is now available from Extras! Changes:
* Added TI83 emulation.
* Added TI83+ emulation (needs some debugging).
* Now exiting when [2nd][ON] is pressed.
* Now preserving emulation state between runs.
As always, the TI83 faceplate image has been created by Andrew Zhilin (wazd).

Thank you so much for TI-83 emulation. Its the calculator I know and use.
Just one request: Instead of an icon for every single calculator (Which is now at three already), it would be better if there was just one icon, and at first launch it asked which calculator you want to use. Then, if you wanted to change it later, you press the menu key to show a list of calculators.

I'm pretty sure I have the latest version of AlmostTI installed, I can't find any newer ones in the Extras repo but I don't have the TI-83+ emulator? Do you have to run it from the console?
Also, a bug I noticed in the TI-83 emu was that when you go to the table of a graph, the numbers are really messed up and unreadable. This also happens in the graph when you are tracing the function, the y and x are unreadable.

The version in Extras is the latest one. It has got problems emulating TI-83+, this is why TI-83+ option is not available.

It is also a known bug. Will be fixed in a later version.

just a big THX for this emulator, looking forward to use it on the N900! :D
(can I also ask if you fixed those bugs/features? ^^ )
edit: i imagine you're more busy porting some other emulator(s) to freemantle though (GBA?), so, just hoping it'll come in the next few months.. :)

could be useful for somebody (the official TI-85 guidebook in english):
http://education.ti.com/downloads/guidebooks/graphing/85/85book-eng.pdf
(~9 MB)
Just a small request, it'd be very appreciated if you did this, and it doesn't require much work (if you haven't done this yet already). If it already exist, then I must appologize, becuase I haven't had a chance to try this emulator yet.
Could you possibly make a TI-84+ Silver Edition interface for the TI-83+ platform as well? It shouldn't be an issue, since it has almost the same hardware as any other TI-83+ calc, the only difference being it includes a built-in real-time clock (however, I'm not sure about if there are any other differences as well, of course besides the hardware differences that doesn't matter for an emulator, like USB-port or more internal memory).
The reason why this would be nice is not only because I'm used to this design, but also becuase there is an amount (although very small) of TI-games that require a clock, which as far as I know, the other calcs lack (besides TI-84 series).
I almost forgot to ask if this will work on the N900 (Maemo 5) as well, or if it needs to be remade for the newer version of the OS?
Could you possibly make a TI-84+ Silver Edition interface for the TI-83+ platform as well?
No, as I do not have TI84+ or TI84+SE firmware. In fact, distributing such firmware publicly would be a much worse problem than distributing the ancient TI85 firmware. So, even if I add TI84* to the application, you will still have to provide your own firmware.

It already works on N900. You can find it in the Extras-Testing repository for Fremantle.
I got my N900 just today, like several hours ago. Anyway, I'm planning to use this app.
I would like to know how to use the Ti83 and the Ti83+SE on this firmware.

Install the app
run the app
click the Ti-83 icon

For some reason, I don't have the option to choose which calculator I want to run. It goes straight to the Ti-85 calculator. Unless I'm missing it, but yea, it goes straight to runnign the Ti-85.

You have to press one of the physical buttons (assuming your using the n800 or n810) and it'll ask you which calculator to switch to.
It would be nice if you can elaborate on the physical button part. And, nope, I'm not using the N810, I'm using my newly bought N900(6 hours ago, if you still consider that new). I have absolutely no idea how to choose which calculator I want to load.
W00t! This is definately the FIRST app to download and install when I get my N900!!! :D :D :D

Hold it in portrait mode and tap the left upper corner. Easter egg ;)
Really nice app, using it on a N900.
If I recall correctly, on a real TI85/86 the up/down keys could be used to "scroll" to previous/next calculations in the main screen. This does not seem to work on the emulator.
The left/right upper corner buttons should also be visible, they are a bit hard to find for a first-time user now :)
Lol as i said above this was the first application to install!! :) but I am experiencing a small problem... when I choose the TI83 and TI83+ and the TI83+SE it says that i need to dump the firmware from the calculatoe then putting the rom file somewhere... anyone have the roms for those?

Nope, you need to press [2nd][enter].
By the way, I'm running the newest stable version in Maemo 5, and the key coordinates seem a bit off. On the TI-86, I have to aim for "conv" to press 8 and "test" for 5, etc.

You are supposed to own the actual calculator, then you can dump the ROM.
On that note, does this pose a threat to the maemo community due to copyright infringement? The way i understand it, it includes the TI85 ROM in the package. We need to be careful not to package IP with the emulators on m.o to keep things all legal and stuff.

I strongly doubt TI85, TI86, or TI82 ROM will make any difference, but may remove TI83 ROM in the next release, just to be safe.
ok i have both ti83 and ti84 how do dump the rom?
and don't take off the ti83 on the next release keep the option there but for whoever has the calculator can dump the rom an put it there that's legal. but the question now is how do i dump the rom and retrieve it? thanks
Ok simple google search got me to this:
http://calcg.org/cgi-bin/forum.cgi?t=7996
But how do I do the 'ASM(' ??
I found the ti-83 rom online.. and I put it on my phone.. it loaded correctly but I noticed that the skin is a bit messed up.. like the left side is a bit off and it doesn't use the full "screen" on the calculator.. which is annoying because it's already small.. and by it not using the full screen it's even smaller so it's a bit harder to see when you graph and stuff.. can you fix the skin? or at least guide me on how to make it use the full screen? thanks.

Does the TI 84 SE work on the n900? Its greyed out and the .png is missing in /opt/ati85. I have the firmware dump for it but am having trouble getting it to work.
Possible to somehow install the program polysmlt onto the calculator?

TI-92 and TI-89 are based on a different architecture than the one emulated by AlmostTI. Right now, I have no plans to support this architecture, mostly due to the lack of time.
Nice app man. But what about the nspire/cas? I'll stop taking my calculator to school and i'll start using this.

I can run the TI-83 which is great but I would really like to run the TI-83+ since that is the one I got and the most used to...
Is there a way to get the TI-83+ working on my N900??
Thanx :)
Does anyone else think that the touchscreen is a little off in relation to the button placement? For example, to get a response, you have to touch below the button; if you touch a bit too high, it will register as the button above it.
The touchscreen is calibrated, so that's not the problem.

EDIT: By the way I noticed that there's a png file for the TI84PSE in the source files of your application..
I am talking about this:
http://www.farahfa.com/uploads/TI84SE.png
EDIT2: So I copied both the rom and that png image and the option of selecting the calculator in the menu didn't work...
I renamed the rom to TI84SE.ROM and the image is named as TI84SE.png...
What can I do to enable it? If there's a way..
EDIT3: I also noticed that the png isn't complete yet, some of the symbols (2nd symbols) are half-drawn.. maybe I can fix that using photoshop..
Ok I worked on it a little bit and fixed some of the symbols like the Catalog, Square root, the Y=..
It still needs a little bit of work, like the alignment of those symbols are a bit off.. but it's night time here and I am tired, so I will work on it tomorrow morning..
Here's how it looks now:

Yea, I do have the TI84+SE skin image, drawn by Andrew Zhilin (wazd). I have never had TI84+SE ROM though, so the chances of it working on AlmostTI are pretty low. Have to play with the ROM a little bit before it works. Sorry.
Ok now you have it.. Please Please Please.. Pretty please work on it! :)

sometimes the touchscreen must be calibrated multiple times. test the calibration with some drawing software for example.

AlmostTI is one of my most used apps on my N900. I normally use it when I can't be arsed to get my TI89 out of my backpack. If you get Ti89 emulation working, you'd be my hero. (I know you said it wasn't in the works though, I'm still grateful for the TI83 emulation though ;) )

click the top left of the screen where it says Almost Real then you can change it. you may need the ROM for the TI83+ though.
just wanted to also say AlmostTI is brilliant. thanks.
