Flash Drives on a Calculator
Posted by Michael on 12 September 2006, 04:43 GMT

[I have mass storage devices on a mass storing calculator!]As the result of a group effort between myself, Brandon Wilson, and Dan Englender, we have released msd8x v0.94, which allows the use of ordinary USB flash drives with a TI-84 Plus. Brandon has been laboring all summer long on finishing the driver and GUI to be acceptable for public usage, and thanks to his dedication and adding of nifty features it is at last at the stage for a general release. Information on downloading and running msd8x can be found at the WikiTI calculator wiki.

With the appropriate cable, you can browse, modify, and copy (in both directions) files between a flash drive and the 84+'s RAM and/or archive. msd8x also supports the running of ION and MirageOS programs directly from a flash drive.

Even if there was one...I would not do me good.
My Ti92 plus has NO usb connection. :(

Woah, calm down, I've never seen that many exclamation points in a row before. Do you mean the 89 Titanium? (None of the other 68k calcs have USB ports)

of course I mean the titanium. why should i care about other calculators? my calculators are the only good calculators. it's all about my calculators.
Ahahahahahahahahaha! Wa ha WA ha Wa hahahahahahahahah!
i feel evil today

Dude, calm WAY down.

Who knows what manner of deviltry TI put in the Titanium's code to stop this kind of thing? Maybe they want you to use /their/ link API, and not access the USB port directly.

TI doesn't like usb8x either and yet here we are. It'll happen someday.

You know, I'm starting to think that TI is just adding features to their calculators to see what the programming community can do with them. It actually makes some sense: all TI does is add the hardware, and then the programming community supplies the time and brainpower figuring out how to use the hardware...seems like a win-win situation to me.

I hadn't thought of it that way before, but I wouldn't be surprised if you were right.

I wonder how long before they start making OSes that are specifically designed to block out scripts used in our programs?

I don't think that's likely, actually. I think TI has pretty much decided that ASM programming is here to stay, and that they won't be messing with it much. It's bad for business, so to speak :-). Plus, TI probably also realizes that such a move would be very antagonistic to the TI community and spawn many attempts to get around the blocks....and TI doesn't like to be shown up by a bunch of amateur ASM programmers...

That said, one of these days, a complete third-party OS will be developed (a number of people, including myself, are working on various OS's right now), and then TI will be feeling the heat...

I've tried a few that are out there and they arn't very good at all but, it's proof that if you can get around the verification process, you can install a 3rd party OS

HAHAHAHAHAHA!!!

This is an old post, so I know nobody's likely to read this, but I have one thing to say to this:

Nspire!!!!!!

Does not even support for most BASIC features!

I want an 84!!!!!

The only problem with this is that in about two years or so, the people who write the SATs will ban all calcs with a USB port :(

But by then I will have taken the test already! :D

Great job, guys. :D

Re: Re: Flash Drives on a Calculator

no, first, TI will write an OS that will block out the usefulness of our programs and tell the SAT people who will then ban *all* calculators and add another section to the test, therefore making it nearly impossible to pass

I don't think they would because it would be obvious that you'd have more than a pencil and calc out -- besides, it wouldn't help on the math section and then you have to put the calc under the desk on english sections

Naw, that won't happen. TI has no interest in blocking these programs. In fact, I don't wonder if some of their programmers have downloaded these 2 apps and are marvelling over their innovative use of the calculator's hardware.

As for the SAT people, they could just ban graphing calculators, or just ban all attachments to graphing calculators. If you were caught with any kind of attachment, your test would be instantly confiscated, no questions asked.

That said, the sneaky people would buy a kickstand case, remove the stand, and attach the flash drive in that location. Then, you'd modify the calculator case around the USB port to snake the wires down the inside and out through the battery door to the flash drive. Voila! Covert external hard drive!

Better yet, bypass the exterior of the USB port and just attach the individual wires directly to the appropriate pin inside the case. No one would be the wiser.

And even better, spring-load the USB connector coming out of the battery case to retract when disconnected from the flash drive; add a lever somewhere along the side of the case to pull it out again. This way, you could take the cover off the back of the calculator and put it on the front just like normal.

how about we just add a hack to install a USB miniSD reader?

Oh man a USB card reader would be all the awesomer. I remember when I first got into calc programming I was soooo frustrated with TI because HP's calcs seem so much more advanced-- the upper ones have a built in SD slot.

Of course this program (tytytyty) makes everything all better, though.

I don't know how big they are but if we could take apart a miniSD reader and the calc, we could cut a small slot somewhere and mount the reader...then connect to USB and it's done!

I could be wrong, but I thought there were some USB card readers that use the generic mass storage driver?

This may very well be. I have one, but it draws too much current.

I tried one and it said it was FAT32 even though it was FAT16

I think that's one of the bugs being worked out

I have (well, my family does) a USB card reader that accepts a generic USB Storage driver but I don't have access to it right now. I have one that uses a driver I'm not sure of but the calc sais it's FAT32 even though it's not. (see my list of tried devices)
