Why Do Calculators have a Headphone Jack?
Vložit
- čas přidán 6. 07. 2024
- On nearly every Texas Instruments graphing calculator, there's a small "headphone" jack along the top. While the port wasn't originally designed for audio, there are some pretty interesting external hardware hacks that can be done through this port.

Yeah same for me because we used casio and don't sell ti in Australia and I can't remember them having a 2.5mm jack although they did have some i/o port
Edit: just quickly looked into it and Casio seem to have the 2.5mm port and promote it as a feature for external data logging

Expensive parts and production
@@anderson9244MLG what expensive parts. Maybe 10 years ago.
Texas Instruments has a monopoly on the school calculator market, so they can screw over whoever they want with their ridiculous prices.
scale/volume. calculators are nothing to the volume of smartphones
Remember that Gameboy recompiler that turns any Gameboy game into a TI program?
Add TI Link Cable support to that.
No idea how difficult that would be, emulating the GB link protocol might have some serious overhead, but it'd be cool to see
TI link is probably not fast enough to transfer at GB link cable speeds
Funny thing about the keyboard, TI actually made one for their calculators! I got one to go with my TI-89 titanium a while back, and it came with a cool sliding case with a kickstand inside, so you could prop it up while typing.
The weirdest part about it was that it lacked a number pad. I thought that was a strange thing to omit in a calculator. But it works great for apps like NoteFolio.
TI-92 with its built in qwerty keyboard still beat it though- actually took class notes on that thing
It doesn't need a number pad because the entire calculator is, well, a number pad.

Used a Ti83 back in Highschool and College, 1997-2005. I hooked it up to my computer many times and downloaded and uploaded many programs. I never knew 2 calculators could be hooked together with the IO port. 20 years later and I'm still learning, thank you!

My thing was making a set of equations that would take the longest to graph.

I've always considered these calculators to be more like mini computers then just calculators, they remind me of old computers such as the C64
That analogy may be closer than you realise: you see, all the TI-8x models except the 89 have a zilog Z80-compatible cpu; the 89 and the voyage both have a motorola 68000 cpu

@@fadrium1464 If you look at this bit here: en.wikipedia.org/wiki/ENIAC#Main_ENIAC_parts you'll see that ENIAC's architecture is very different from the computers we know today, i therefore think a direct comparison will be difficult; i certainly don't have the knowledge to do so.

"before usb ports..."
*Cable has a USB connector*
USB ports on the calculator. The newer models have a built-in USB port for uploading
He meant before they put mini USB ports on the calculators
Earlier Sonys had jack-to-9-pin serial... you know, before USB was a thing. The newer USB-to-jack variants I guess just works as a USB-to-serial interface.
Guys, I'm probably wrong but... I think it was just a joke.
the TI-59, TI-58, and TI-58C had an optional thermal printer called the PC100C in late 70's. The 58C and 59 were basically full size computers with programmable functions and the 59 had a magnetic card reader. There were other things made to make it more like a desktop micro computer like a tv out box called video 59 and devices to switch between multiple ROM cartridges.
Tandy also had a thermal printer clear back with their PC-1 Pocket Computer ( I am sure it was made by Sharp, but not sure if any of the Sharp models were sold outside of Japan at the time) Unfortunately for me, I couldn't come up with the funds to buy one, I only had the cassette adapter for mine.

@MaggieOnline Obviously. Their VPAM lineup is truly remarkable. Not only in South America but also in other countries, Casio is a famous brand only because of their Quality within Budget.

I think i have discovered an amazing idea.
If you are having an exam and it allows you to use those calculators, then you can connect 2 of them (1 is at home and 1 next to you). you can make the aux cable send the info to a small database where the home calculator picks the info up ands sends info back. If you don’t know the formulas then the people at home can do them for you.

i loved my TI calculators and Casio graphing calcs. I had some REALLY wild models too (one of the high-end TI models had a full qwerty keyboard, large screen, and could map 3d and 4d functions.), but my favorite is the casio color models that showed up from the end of the 90's through the early 00's. These things were extremely powerful devices, had color, and were much more affordable for the functionality you got. They also used a similar Basic based programming language as the TI calcs, and it was pretty simple to port code from one device to another.
Growing up, we re-released several modded versions of several games, and even made a few (usually small puzzle games, strange ports of pong that had missiles involved, and I wrote a scrolling vector base skateboarding game at one point)
However, ALL of these programs would work FAR better on the Casio, and it was possible to even import (simple) sprites into the code using GET and PUT statements on data matrices that held pixel-color-data (I think it was like number 0 to 3 for the R, G, and B channels, or 2-bit-per-color channel... but you had only 4 colors that could be defined at the same time, it was ARCHAIC to say the least.) or just choose from a pre-set palette of 16 colors... which for a calculator was ASTOUNDING. Just keep it under 48k :D
The best I could do with the TI's was line and circle drawing, and pset/point 'sprite-like' operations, but it was closer to 'vector like operations'... and DAMN slow on the refresh. Most of the games that came out on the TI were, ostensibly, text based, puzzle games, or EXTREMELY simple stick-figure graphics for RPG's and if you were REALLY motivated (and had a math teacher with the link cables that let you do what you wanted because they couldn't teach you anything new anyway... that's what I get for learning calc in 3rd grade >.

Some old devices (70s-80s) had a headphone-type 2.5/3.5mm jack that was used for an AC adapter power connection, sometimes to charge an internal rechargeable battery pack.
I have a wall outlet to 3.5mm jack charging cable from an old calculator. The calculator itself no longer works, but I kept the cable to be enshrined in my "wft even is this" display of weird tech stuff. Whenever somebody asks what it's for, I say it's for listening to AC/DC.

Yes, I did that too. My TI-84+SE was probably among the most decked-out in the entire school. I could play 8-bit MIDI songs with MobileTunes and real music with RealSnd. With USB Tools I connected a USB keyboard or mouse through an OTG cable to the calc's mini-USB port. With MSD8X I could even read text files on a flash drive connected to the port!
Omnicalc, Doors CS, MathPrint, A+ Calc (for calculus), spreadsheet, 3D graphing (faster than TI-89), periodic table, zoomable world map, chat, TELNET, Gossamer, Timerize, starfield screensaver, the list goes on... Even an experimental TV receiver! (although I don't think it worked)
I documented exactly how it was configured because occasionally it would become unstable and things would have to be reset and reinstalled after battery changes. Before smartphones that was the hottest thing for geeks to carry around. Gotta have your wallet, keys, and TI-84. One of my classmates even took apart his TI and added a tiny speaker inside to play music on.

It does include usb and link ports but also has a real headphone connection and an internal speaker to output the graph audio and speech. The accessibility unit connects to the top of the unit, taking up the built in link port and mini usb, so it is possible to remove it and use the calculator normally. The unit also supports braille as well as making it easy to review the screen and other stuff to make it somewhat simple to use it blind.

Gossamer 1.0? :D
TI calculators use that jack/port to insert a communication cable. It allows two of these calculators to talk to each other (among other possible uses).
The speech module is from Orbit Research, and is sold screwed on top of the calculator for $500, as it can also interpret graphs and play them as a series of tones, panning from left to right to represent X, and high to low pitch to represent Y.

I don’t recall it having a headphone jack (this was in 1975, after all), but it must have, considering it was Texas Instruments’ top-of-the-line hand-held calculator when I bought it.
The ti series actually has an official keyboard you can plug into the 2.5mm port. I don't think they're sold new anymore, but I've certainly seen them on ebay
I have a keyboard that works with the link port. It allows you to type out stuff at a decent speed. It's about the size of a netbook keyboard and uses the link port. I find it pretty useful as it works with any model with that port.
