Writing data to a file is significantly slower, anywhere from 5 to 40 KB/s, depending on if the file needs to be grown (and on the sectors per cluster and the speed of the flash drive). Reading data from the file system is a bit slower, maxing at about 80 KB/s. The raw read speed via usb8x from a flash drive seems to max out at about 130 KB/s. It contains a file browser so you can import/export files, and run programs from the drive.

The software this article mentions, msd8x, is a UI to access the mass storage driver.

The mass storage driver (and msd8x) was started by Michael and finished by Brandon.

It contains the low level USB host (think root hub) driver, and higher level drivers for: mice, keyboards, gamepads, EasyTemp (one of the vernier thingies mentioned above), Silverlink (a TI connection cable), and mass storage devices. I wrote a piece of software, usb8x, which configures and controls the calculator's USB port for use with other devices. The calculator has a mini-USB port, so a mini-A to A-female adapter cable is required to connect most devices. Unfortunately the calculator's operating system has no provisions to allow it to connect, as host, to anything other than another calculator or a Vernier data collection thingie. The TI-84 Plus calculator has a USB on-the-go port, meaning it can act as either device or host. Give schools robotics teams, not calculators. Ironically, the place they deal the most damage is probably math, because we end up with kids getting by without understanding order of operations or basic algebraic manipulation. Graphing calculators, not wholly without benefits, do not outweigh the problems they cause. It's encouraging to see kids compare their text adventures with each other, but but 95% of the student body, this toy is pearls before swine.
Even so, very few students actually do this. If you give a kid a programmable machine and free time, he'll program it. If you give a kid a ball and free time, he'll kick it. The other benefit merits a bit of appreciation. I know calculators are capable of so much more, graphing Crossed Troughs and whatnought, but that's too far beyong what you learn in high school to be meaningful. It's just not a very useful thing to learn.

It's easy to imagine how this might help a kid understand how to push around equations like F(x-x0) + y0. The first, institutional use, is that kids will understand Analytical Geometry and Trig better if they can SEE equations. So what do we get in exchange for this? There's two productive uses of a graphing calculator. $100 per high school student, in a system where you have roughly one math teacher for every two hundred students? It's money that could be much better spent too. $100 may not be a lot to most people, but it is for a few. It's expected that most of this will come with the calculator, but that which doesn't is a simple exercise in typing to fix.Īlso, there is a problem of monetary cost. but once you do, you can get by without learning the quadratic equation, how to convert from moles to grams, what the relation between physical and kinetic energy is, &ct. Learning how to use the calculator is a bit of a hurdle. Graphing calculators have the problem of really dumbing things down. To this day, I don't understand the purpose of having students buy graphing calculators. High school was not very long ago, and there we were required to use graphing calculators for Junior and Senior level math classes. I recently graduated with a BS in Mathematics.
