Title: Lots of new TI-84 Plus C related images!
Post by: critor on January 18, 2013, 06:18:06 pm
After the official press release earlier (http://ourl.ca/18187) today, TI website has now been updated for the TI-84 Plus C SE.



We can see on their new page (http://education.ti.com/en/us/products/calculators/graphing-calculators/ti-84-plus-c-silver-edition (http://education.ti.com/en/us/products/calculators/graphing-calculators/ti-84-plus-c-silver-edition)), much more details than in the press release:

Screenshots of the calculator itself while graphing stuff, and it's much better in color than on the previous B&W models...

(http://education.ti.com/en/us/~/media/Images/TI%20Education/US/product-details/product-84c-2c-activities.png)

Exclusive image combining the "school property" model and for the first time in public, the TI-Smartview 4.0 software, with a 84C emulator :

Well, I feel snubbed. I.Q. Joe gets to beta test the calculator---or at least the new SDK---but nobody from the community does.

Price: $130 USD from SchoolMart (http://www.schoolmart.com/texasinstrumentsti84pluscsilvereditiongraphingcalculator.aspx). I specifically mention them because they're within driving distance for me.

It likely uses the same link protocol, since linking directly with older calculators is supported. Of course, we'll have to add in support for the new OS and APP formats.

New OS and app formats? The apps will simply use a different signing key, and the OS will also use the same format, just a different key.

Well, that's possible but we can't know for sure. I'm not sure if there will need to be any changes made to support 3MB APPs, for example.

I would expect more from what I have to assume they made as a prizm competitor. They have the native asm support, but I'd hope for specs that were close to matching the prizm. It has about 1/5th the RAM of the prizm. I still think this is an interesting calc for how it should be a very easy/popular transition for schools.

Based on the spec saying that the calculator has 21 K of user RAM, it seems reasonable to conclude that the OS is largely based on previous OSes, especially the parts of it not related to the user interface. Ergo, the OS and boot code required for OS and app transfers is already valid. It just doesn't make sense to write an entirely new protocol. It's possible that TI will modify the computer-side 8xk format to prevent people from trying to send a TI-84+CSE app to a regular-series calculator, but I highly doubt any major changes in the protocol.

I think the ugly fonts are to ensure that BASIC programs look as similar as possible on both the monochrome and color models. I actually like the fonts better than on the PRIZM.

Also this calc probably uses 8192 bits RSA keys. I'm sure TI is scared that a super-secret group of TI community member is building a massive computer clusters all over the world to be able to crack a 2048 bit RSA key in less than 1 month, so they probably won't take any chance. :P

Frankly I like the old 96*64-screen font better than this one. It looks like they spent about 10 minutes max on it, and the work done by someone who knows next to nothing about what letters are supposed to look like. :/
They even managed to fudge up the > and > symbols somehow 0.o
Battery indicator could use some work too..
Edit: looks like they've changed the multiplication sign since the last screenshots. It's a start..


So the battery pack's different from the one in the CX?

Nice. Also the font isn't too bad at all, if even bad. It's just something people will have to get used to, but I think it's just nitpicking on the device.

Also, is this new Ti-Connect 4 already out and will it work properly on mac os x now?
Title: Re: Lots of new TI-84 Plus C related images!
Post by: Lionel Debroux on January 19, 2013, 04:38:22 am
From the screenshot, it may be a special version vaguely simulating the behaviour of the calculator, like TI-Nspire Computer Software is, rather than an emulator, like all community emulators are.
Title: Re: Lots of new TI-84 Plus C related images!
Post by: calc84maniac on January 19, 2013, 04:52:12 am
I don't know about that, it seems like the current TI-SmartView is an emulator, since you actually load a TI-84+ OS into it (http://education.ti.com/en/us/software/details/en/7C8C12D62DEA43C28B50F1A3B44CD4A5/ti84plusoperatingsystem-forsmartview).

This is what the current version looks like:

Mine does.

Post by: DJ Omnimaga on January 19, 2013, 02:20:56 pm
It's most likely 1 to keep it as compatible with the TI-82-84 series as much as possible and also probably to purposely not make it look as fancy as the TI-Nspire so that people might still consider the more expensive TI-Nspire CX instead of the cheaper TI-84 Plus C Silver Edition. This is probably also to make sure the fonts remain easy to read. Serif-based fonts such as Times New Roman, used on the Nspire, are not very easy to read on a screen.

Most programs should be compatible, but I doubt there is a way to have a shell that would allow ASM programs to run.

Just convert 1 TI84 pxl to 3x3 TI84PCSE pxls... Black and White are all Fs and all 0s in hex, right?
Title: Re: Lots of new TI-84 Plus C related images!
Post by: ruler501 on January 19, 2013, 10:16:21 pm
That would be simple for BASIC programs, but how would you implement that with an ASM program?
Title: Re: Lots of new TI-84 Plus C related images!
Post by: pimathbrainiac on January 19, 2013, 10:18:30 pm
The pixel commands for ASM can be found in the raw hex, right?
Title: Re: Lots of new TI-84 Plus C related images!
Post by: ruler501 on January 19, 2013, 10:20:12 pm
You'd have to change the programs themselves then it would no longer be a shell, but more of a patch to programs to make them work.
Title: Re: Lots of new TI-84 Plus C related images!
Post by: pimathbrainiac on January 19, 2013, 10:22:03 pm
I mean that the shell will read the raw hex and do the conversion.
Title: Re: Lots of new TI-84 Plus C related images!
Post by: ruler501 on January 19, 2013, 10:29:05 pm
So a shell that auto-patches the executable. That could be hard to write, but it might be possible. I'd let someone else look into it though.
Title: Re: Lots of new TI-84 Plus C related images!
Post by: pimathbrainiac on January 19, 2013, 10:31:33 pm
well, no... It would interpret the ASM by finding specific hex (hex is 8xp asm, right?)

You don't interpret hex. You have to patch it then execute it. It would slow it down a lot and it would be extremely hard to make an interpreter.

Post by: pimathbrainiac on January 19, 2013, 10:37:46 pm
Well, if you CAN make an interpreter, then Omnimaga as a whole should make that the next big project!

That way the transition in the future will be extremely easy!

Post by: ruler501 on January 19, 2013, 10:39:37 pm
pimathbraniac. The whole point of assembler is that it is executed on the processor. We would use an interpreted language like Grammar for what you want.

Title: Re: Lots of new TI-84 Plus C related images!
Post by: DJ Omnimaga on January 19, 2013, 11:30:37 pm
For ASM, someone will probably just update the TI-82/83/83+ unification FAQ to add 84+ color stuff and porting games will be similar to regular ASM except the screen stuff. That's assuming, of course, that the calc runs a Z80. Also Grammer/Axe would obviously require that someone or their authors rewrite them for the new calc :P
Title: Re: Lots of new TI-84 Plus C related images!
Post by: ruler501 on January 19, 2013, 11:39:46 pm
I thought it was already known that it had a z80?
I remember people were already running test programs on it to find out about it.
DJ_0 I'd think the main thing for making old asm programs run on the 84C would be to patch the display routines and maybe some of the variable access and stuff. Just find where things have changed and see if there is a reasonable way to patch that.
Title: Re: Lots of new TI-84 Plus C related images!
Post by: DrDnar on January 19, 2013, 11:54:38 pm
There are serious theoretical issues with what pimathbrainiac asks, namely the Turing Completeness Theorem. There's no perfect way to tell whether a given byte sequence is code or data until it actually gets executed by the CPU. (In fact, some very clever coders write code that is both code and data (e.g. a sprite whose bitpattern is also a routine), resulting in code that is nearly impossible to change.) You'd probably need to do emulation or very careful dynamic recomplication. Most games are released with source code, so manual porting is the best option. Nevertheless, the set of all Z80 assembly programs ever written is finite, so writing a program to port them is not impossible. That is, it is possible to map a finite number of inputs to a finite number of outputs, but finding the transformation algorithm you need is rather the non-trivial problem.

Post by: chickendude on January 20, 2013, 04:19:25 am
For programs that use ion routines and don't do any direct LCD work you might be able to write a shell that replaces ionFastCopy and perhaps the sprite routines to work with the 84+CSE. I guess it also depends on the gbuf (which likely won't exist anymore, at least not as a block in RAM) and saferam locations.

Yeah but has anyone actually managed to get a program to work? So far it seems like any attempt at running code caused crashes and stuff.

As for emulation I guess it might be useful for old games if people want to run them exactly how they were in their monochrome form, otherwise porting them is indeed the best solution (and you can release a pixelated version if you want to preserve the original look)

Lol on the TI website in the lists of features for TestGuard on the TI-84 Plus C Silver page it says TI-83 Plus C Silver Edition. Most likely a mistake, although this was weird to see it in every TI website languages/region http://education.ti.com/en/us/products/calculators/graphing-calculators/ti-84-plus-c-silver-edition

Also why is there a 84PCSE page on every version/translation of TI website, including Belgium, but not France? ???
