I'm sorry to tell you it is even more complicated than if it can run doom. Does this count as doom?

Another definition i have seen is the QWERTY keyboard restriction. If i remember correctly some good calculators from Texas Instruments have abc keyword to be allowed on some big math tests in US. (Or is this maybe just a myth in Europe?)

View on HN

TI-83 has alphabetic input (but not QWERTY)

Also, that's quite clearly not Doom. A Doom port must have at least E1 of the original Doom, with minimal layout changes. That means multiple levels, and up/down moving platforms, by definition.

That video looks more like wolfenstein

Not a myth. College Board has a blanket ban on QWERTY keyboards in tests, so TI Nspire line has ABCDEF keyboards

That is insane. Why?

But then, a lot of things about the College Board are pretty nuts: It is the reason that graphing calculator companies can continue to scam the public by selling overpriced machines running at absurdly low speeds (Their most popular calculator is a 6-15MHz Z80, with 48-128K ram (but YOU, the programmer, can only access 24K): That's pathetic, and yet you can buy a chromebook (a LAPTOP capable of running the famously resource-hungry Chrome) for the same price). The Plus CE did a bit to improve this, but it's still less capable then the phone in your pocket: That is inexcusable).

The Nspire line isn't that bad.. It's not high-end by any means (it's still a damn calculator), but it at least got the lineup to 21st century.

Yes, but firstly, the Nspire line is nowhere near as popular, and secondly, everyone who would ever need such a calculator is already carrying around a phone that's more powerful, and can run better software (Android has ports of Maxima (the open source descendant of MACSYMA) and REDUCE, as well as simpler CASes), as well as full support for all the calculator software (Android runs Wabbit)

K12 teachers don't want students distracted by phones in class. It's much easier to police which physical device a student is handling than which capability they're exercising.

Even in BYOD netbook world, you can bet all social networking and messaging is blocked at the web filter. (Sometimes time-based restrictions open it for lunch and after school, sometimes not).

...Which is why they get away with it. But the calculators are still absurdly overpriced.

Besides, any student can load all sorts of software onto those calculators fairly trivially.

Wait, why would they ban keyboard layouts?

I imagine they were trying to define "computer" versus "calculator," and then banned computers.

probably an outdated heuristic for distinguishing a "real computer" from a "calculator".

For an earlier example, see the TI-92 and TI-89. The 89 is basically exactly the same as the 92, but with the button layout of the TI-81/85 series.

Programmable calculators and computers are rather close, no?

What about eCig batteries?

I've always considered a TI-83 to be a computer in its own right. It's called a calculator, but for as long as it's been a thing, it's been used as a more general computer as well.

TI Voyage-200 and TI-92+ had a QWERTY keyboard, and almost the same internals as the TI-89.
