Texas Instruments is attempting a change, announcing they will release a new member of the TI-84 family in time for the 2013 back-to-school season. The TI-84+C will be the first TI-84 to have a color screen, hence the "C" after the "+." The project is still being developed, so TI has not released much of the specs. At its core may still sit a Z80 at around 15 MHz, resolution of the screen is still unknown. A vague "Spring 2013" release date, and a notification sign-up page is all that was given out.
Users will be able to graph directly to uploaded photographs, but unlike the Nspire, pics of common file types, like jpg or png, will need to be converted first. The new TI-84+C will use a similar operating system to the old models but will include new options for the color screen, and the button layout will be identical to the other TI-84s.
Before the release, Texas Instruments wants to rewrite the more popular TI-84 programs for compatibility with the new color screen. However, the TI-84+C will be released with App4Math, CellSheet, EasyData, Finance, Inequalz, Plysmlt2, and Smartpad, preloaded. New apps will continue to be released throughout the summer of 2013, including compatible versions of Areaform, CabriJr, Conics, Periodic, ProbSim, SciTools, and Transfrm. This new calculator will also come with an improved version of SmartView for teachers who incorporate calculators into their lessons. This SmartView will still be compatible with previous TI-84s.
The previous TI-84s, the "Plus (+)" and "+Silver Edition," will still be available with no updates planned; priced for the budget-minded. Good news for poor college students considering the new TI-84+C will have an MSRP of about $150.
Being similar to previous 84s, this calculator will most likely be allowed in standardized tests, but institutions have decided nothing yet. As a former engineering student, unless there are some useful apps developed to pump more life into this calculator, I cannot say I could see this version becoming exceedingly popular, just fresh paint on the standard. With that said, it is a good bet that TI graphing calculators will continue to be used in classrooms everywhere for a long time. It's even more heartening to know that the Z80 and 68K are still in demand.
I once found a TI calculator in a drawer in a lecture hall at the university where I work. It was a graphing calculator and it looked like someone had used a magnifying glass and burnt dimples in the display. This thing had been in the lecture hall for sometime collecting dust so I had no problem taking it. There were enough dimples to make seeing the display unpleasant. I tried to fix it...right. I got to the display and started peeling up the plastic on the surface. That was when I started understanding how the display is assembled. The plastic polarizer had the dimples. When that got removed, the info on the display could not be seen anymore. Then I got an idea. I use polarized sunglasses, so I put them on. Vola! I could read the display but without the glasses the display was blank. It also meant the the calculator had to be orientated right in order to see the display. Because I was going to school at the same time, this gave me some ideas which I never acted upon. After all, it was a TI calculator not an HP. I use an HP.
RBedell, I agree. The calculator still has a place in today's smartphone, tablet society. I use "Real Calculator" on my DroidX and Internet Tablet but the TI89+ graphics calculator has a really cool interface for Arduino controls projects. I also agree the embedded menus to obtain math functions on the TI89+ kind off discourages you to use it because of the added access time. But like most engineers, I'll never give it up because it represents an era of learning engineering, mathematics, and solutions in the palm of your hand.
In my college days I had a Casio calculator. You enterred equations in a format that was very much like the BASIC language. The really slick feature was the Back Arrow key that would bring up the last equation enterred so you could edit it and hit exe for the next answer.
Encouraged you to learn how to manipulate your equation so the variable that needed to be changed was at the end so it was easy to backspace a couple times, change the number and get teh next answer to fill in the table.
Plar to rectangular and rectangular to polar were a snap.
Unfortuantely, because of tight household budget, my wife used it when shopping and thedisplay didn't survive her purse. Have aleays wanted one like it but have never found another...
I agree with the HP RPN being superior, and I still use my (1987!) HP-42S. I don't quite know why, but it is significantly faster than my HP48G. Programming isn't too much of a problem on either device. Long live the SQUID! (Obscure HP-41 hacker ref)
But what do you do when the schools REQURE a Ti product? Must be a sweet deal for Ti.
Slide rules! ... being a bit of a smart xxx in high school. Teachers would give a test and say 'no calculators'. So I learned to use a slide rule. Then one day in class, a test, no calculators. "Teacher, can I use a slide rule?" "No" "But its not a calculator." "You don't know how to use one." "Yes, I do. I learned to use it." ... "No!" grrrr.
Another time/different class, after getting the TI-58 programmable, on a trig test I could not remember the equations to solve a problem. I could use the calculator and the program library that came with it, to get the answer but we had to show our work. What to do? Ahhh! De-complied the triangle library routines and extracted the equations. Then showed my work. Got the test back. The problem was red X-ed. I didn't solve the problem the way it was taught in class therefore it was wrong. So much for creativity. :D
In high school, I had saved up money to buy a TI-58 calculator. I was so excited. I even wrote a program that would calculate 2^x to the last digit (x limited to the avaliable memory to store the answer). It took hours to calculate 2^1000.
Later in college I bought a TI-80 something. Took it back for a refund. The advanced functions where buried in menus. Ended up with an HP-48 and took awhile to get used to the RPN. While I never learned to program it, I did like it.
So what do I used now? On Widnows I run the HP-48 emulator. On my Galaxy S3, Droid48, another HP-48 emulator. I still use the 'real' 48 when at home. But I would not throw the calculator out with the 'old concept'. The stand-alone calculator will have a place for a long time. It represents a common reference for teaching and everyday use.
But before the smartphone, engineers traded the calculator for computers. Computers can do far more than a calculator and do it faster. Yet, calculators still survived. The smartphone is nothing more than another computer with perks. Calculators reside in that zone between teaching the math and applying that math to real world problems.
I'm thinking a iPhone app can blow all of these away for a few bucks, if not free. Granted, it's nice to have dedicated buttons with tactile feedback, but students these days?
Had to laugh too at the 'high' price. I'm a geezer, and we had students spending up to $150 on a good slide rule in the day. My first gee-whiz calculator which could do only most the things a slide rule could do, was (if memory serves) an HP-35 which was north of $300 in 1970 dollars, and working engineers immediately 'had to have one'! That thing was still running fine when it became too much a dinosaur for even a cheapskate like me.
wow! Ti calculators are just now going color? I had one of those graphing marvels for a few semesters and even replaced the stolen Ti-89 with a the Voyage 200. Of course you can't use it on an exam of any kind. So I bought a $20 scientific calculator and was able to everything with it. Personally, I think it is silly these schools put that on the requirement list.
The price is going in the wrong direction because TI has no competition. The article states in the second-to-last paragraph on the first page why the price has not gone down in 20 years. Instituitions specify TI calculators exclusively.
It's a VERY steep price for a single-function device. I disagree strongly that adding color is the right step for consumers.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
