You can leave the TI graphing calculator at home thanks to this. As with pretty much all emulators, this depends on a ROM image from the actual hardware to work. But if you have one of the supported calculators (TI-83+, TI-83+ SE, TI-84+, or TI-84+SE) you can dump the image yourself and this should work like a charm. [Christopher Mitchell] calls the project jsTIfied because he wrote it in JavaScript and HTML5 (that’s where the js comes from) and it’s based on the Texas Instruments line of hardware (hence the capital TI). After agreeing that you’re not getting any ROMs from his site you can choose the file to load on your browser. The image of the calculator has working buttons and will show the boot screen just like the real thing.

You can use it like normal but you can load load up programs for the environment. See this demonstrated after the break. We’ve seen some arguments online about the price of the TI line over the years. Prices haven’t dropped much over the decades even though they’re making pretty much the same hardware. It’s cool to see someone figure out how to emulate the hardware — and on a web interface to boot! But we’re left wondering why TI isn’t selling an equivalent app for iOS and Android or at least leveraging what must be millions in each production run for a lower retail price?

There’s very little pressure to lower their prices since the only bulk purchasers of graphing calculators are high school and college students, and most of those courses require TI calculators so the teacher doesn’t have to explain TI, Casio, ETC. They’re required for math classes so professors can reset the memory on test day and be more assured that the students aren’t cheating. Can’t do that with a phone. Anyone who doesn’t need to graph can buy a scientific calc for $5, anyone who needs to but doesn’t need to be ‘cheat free’ on test day can use a phone or a computer – thus a niche market which can complain but can’t do anything about the price. To put it bluntly, the whole scheme is crap. I had to purchase three different types of “the last one you’ll ever need” TI calculators.

I purchased a total of five because three of the damn things took a dump, twice on test day with one forcing me to retake the class again. I purchased a Casio (IIRC) and it still works perfectly despite being in my filthy truck for years. This was all before teachers started erasing memories mind you so it wasn’t that big of a deal to use the Casio. I blame TI and anal teachers for making my advanced math courses absolute Hell. Of course when I started my programming classes and bought my first laptop, I never saw my calculators again. Two reasons why TI won’t cut the price. Monopoly on the education market.

The TI-99/4A and their stupid price war with Commodore and their much inferior VIC-20. Rather than emphasize the features and how much better their computer was, TI tried to match price with the VIC-20.

Commodore could afford to go a lot lower. Not going to see TI in another price war like that.

Remember TI’s highly rated laptop computers? They gave that division the axe rather than cut profit margins to the bone like other companies.

TI likes their education market monopoly on these calculators. They tried to do that with the software on the TI-99/4A but it backfired as all the other computer manufacturers supported 3rd party programmers and software companies. TI wanted a cut of all the action, especially as their profits on the hardware dropped. The calculators give TI everything they screwed up on the computer in the 80’s, a monopoly and high prices and profits.
