Are they still the only ones you’re allowed to/supposed to use?
If yes, that’s why. |

I learned on the TI-83 in high school about 25 years ago. When I started college I bought a TI-86, hated it, returned it for a TI-83. I've used it regularly for school, then home and work since then. I don't think it's the best there is, it's just what I know.
That TI-83 just died within the past week. I'd like to get a couple more. |

They went from $100 25 yrs ago to $275. The technology haven't changed so I'm not sure why the cost hasn't gone down.

I had a statistics teacher in college who said he bought one of the very first desk-top electronic calculators.
I had plus, minus and multiply - no divide. $600 in back-then dollars. |

I had a half dozen of them at one point, never did use 'em. Did all my graphing for calculus by hand. It's amazing how often they're left behind in college classrooms.... |

Quote HistoryQuoted: They went from $100 25 yrs ago to $275. The technology haven't changed so I'm not sure why the cost hasn't gone down. It makes you wonder if part of the reason the cost hasn't gone down, is because the technology is so outdated/primitive compared to modern devices? I.e., to produce those legacy units requires the use of materials and manufacturing capacity that could otherwise be used for other products; thus, in turn, an "opportunity cost" is added to the total cost, whether that opportunity cost is clearly delineated or subsumed by the other components of said total cost. Of course, other factors such as direct and indirect market manipulation (e.g., "the only acceptable calculator for this course is X unit") undoubtedly play part as well. |

And why still model numbers based on the 1980s (ti-82, ti-85, etc). Model numbers should be like ti-2k22. ??

When I was a pawnbroker, I'd pay $10-$20 for Ti-84 school calculators either on pawn or buy. Never had any trouble getting all I needed for back-to-school season, when I'd sell them for $50 each. If I had any left over, I'd box them up and send them to one of the online places that buy calculators.

With them being the de-facto standard calculators of American education, the normal driving forces in the electronics industry don’t really apply.
“Newer, faster, better” holds very little weight in the graphing calculator market. Couple that with them being a relatively speaking low volume item since generally you will ever buy one. Hell, mine is 20 years old and I still use it almost daily. |

They are the same price because inflation raises it, and electronics generations reduce it, and in the case of calculators they just happened to balance out.
My high school calculator was an HP 41C, which worked for about 10 years and then I used computers, not calculators. |

I was an early adopter and got a TI-81 when it was first offered in 1990. I'm guessing the prices haven't moved due to the processors being used (Zilog Z-80 in the case of the TI-81) are 40+ years old now and they are quite cheap to make these days.

I pulled my TI-83 out last year because I needed to do some number crunching that would be easier to off the phone and found out a couple of pixel lines through the most used part of the display were dead.
