5:32 To avoid cheating, teachers had us reset our calculators before exams, and show them the "reset completed" screen as proof. So obviously, someone in my class simply recreated that "reset completed" screen, and showed that instead... He's a programmer now.

That was such a thing in high school, I really only specifically remember doing it for the SAT but I’m pretty sure they must’ve made us other times. Now 6 years of college later at three different universities probably hundreds of tests I haven’t had a single person ask me to reset my calculator. Hell I had a professor that recommended or at least approved of me writing programs to solve the test problems. Double hell, I’m pretty sure that the high school thing about forcing us to reset calculators made every student hyper aware you could cheat with them. Triple hell, if you could somehow get enough notes and programs into your calculator to actually raise your SAT score any significant amount you probably earned it lol

[@likebot.]

I'm a proponent of cheating. It's a resourcefulness that employers use.

I was one of the only people at my high school who would track down games online and load them onto my calculator, so I have such fond memories of people seeing them and saying "you gotta give me that one!" and watching them spread across the school. Such good times.

I learned BASIC on an Apple //e. But I was able to use it when I had a TI-85 in Middle School. In high school I took a qbasic course as a prerequisite for a C course that was my high school course catalog but was never offered. I did learn a little more sophisticated programming though by taking is a formal class in high school and advancing beyond the self taught basic from grade school.

Came back to bite me on the SAT later when I couldn’t remember any geometry haha 😂 Totally agree, let kids program and create. I learned more math through programming than I ever did through lectures anyways.

[@geekmug]

I was involved in the TI calc community in the late 90s. The real break through moment was the TI-85, which was the first graphing calculator to include the graph link capability. Along with that came the ability to hack a backup file to insert custom code that enabled loading assembly programs, which was developed by David Boozer. Dan Eble used it to make ZShell, which made assembly programs easy to load, run, and share. Everything that came after is a derivative of that idea. When the TI-83 was released, support for launching assembly programs was built-in, and that support is most likely due to Pat Milheron, one of the lead developers at Texas Instruments for the TI-83. As far as I know, Pat still works at TI on graphing calculators. If there was anyone I would want to interview for this story, it would be Pat.

[@MrNoahTall]

I bought a TI-85 when I went to Accident Reconstruction school for all the crash physics and trigonometry formulas I had to use. Most of the students used HPs, and were given the program steps. I had to write my own which paid dividends later during cross-examinations where I could explain my ranges thoroughly.

[@SteinGauslaaStrindhaug]

One of the most popular programs on my school was a Casio Basic program that (almost) pixel perfectly recreated the receipt screen saying the memory had been wiped. I think there was one corner that wasn't possible to draw on (because that's where the progress indicator was) that would tell the screens apart, but no teacher knew about it. We mostly used it just to avoid having to delete our games rather than for cheating... After all we were allowed a formula leaflet and a calculator so there was very limited what we could put into a calculator that would be any more helpful.

Our school required us to get Ti-83's in 1996 when I was in year 9. I was that kid who built a DIY RS232 comms cable to download and distribute games like Blackjack, Poker, Space Invaders and Penguin to other students. It was always rewarding to see a kid I didn't even know playing a game which I knew I had introduced to the school.

As many others have chimed in, I also got my start on programming with my TI calculator in school, and now I'm a software engineer. The big difference that I've seen among students learning programming for the first time is that if there isn't drive/passion, they don't usually grasp the concepts or do too well. Programming is at it's core just problem solving, and if it's not a problem that you're passionate about, you won't allocate the necessary resources to actually understand the why of the solution if you come up with one.

This is very true. Many people just learn it because they want the money and the "easy" job that it requires.

At my school we got Ti-83s in 1998. We were so pleased with them. At the time Drug Cartel, Turbo Blockout and Tertis went right round school. Tetris was really good.

[@agranero6]

The games are not programmed on the calculator (via PGM), the calculator software originally ran on a Z80 processor, and for saving the cost of rewriting the the software TI decided to emulate the Z80 inside a much more powerful ARM CPU (the same family that exists on your phone). And then they came back to use Z80 end 6800 processors. So porting those old computer games that used Z80 to a calculator like that is fairly easy. Compared to programming for a cellphone where you need a lot (I MEAN A LOT) of boilerplate, programming to those machines is really easy with a much lower wall to climb.

[@dalegaliniak607]

Oh yeah, I'm one of those people who got their first start in programming on the TI-83. Stupid stuff, usually editing other people's basic games. I remember changing a racing game that when you pressed a button, it would take you to a menu that had a whole bunch of cheat notes for every unit in our Algebra II class, including solvers. I felt so clever (because what? a teacher was going to let me play a racing game during class?), but I probably learned more _making_ that app than in the actual practice problems...

[@ChristianKoehler77]

Do not forget HP! The HP48 series wasn't common at highschools because it wasn't designed for that and probably too complicated. But it was the de facto standard in college classes related to engineering. Laptops were out of reach for most students in the 90s, so the HP48 was the first programmable, pocketable device for them. Many of them were incredibly creatine and very skilled (remember, we are talking about computer science students). Hardware modifications were also common. Yes, overclocking was a thing!

My dad gave me a ti-92 plus for my 8th grade algebra 1 honors class and I absolutely loved it.

I did make games on my calculator, but more often I made programs to make school assignments easier. One day, my chemistry teacher got wind that I had made a program to instantly solve some multi-step homework problems, and she told the class, asking if I were willing to share it. I was willing, but I thought it’d be funny to add a secret line of code that changed the program to spit out random numbers. No one (except my friend who suspected I was up to something) was any the wiser until we compared homework the next day. Pure confusion. I gave everyone the right version of the program in time for the test the next day. Another time, when I was a senior, I made a calculator program to ask out the girl who sat next to me in AP Physics to homecoming. She selected the “yes” option. Very smooth. Good times.

I remember this very well I still have the computer interface cable to load the games in a box somewhere. I think ti-basic was the first programming language I learned but never got into making games. I had one math class I wrote a bunch of programs to do the work and was using them all year. Then one of the other students did the same and asked the teacher if he could use them at the end of the year. She determined you have to really know the math to know how to program it and let us use them on our tests. She made the final intentionally longer than could be finished in the time and graded on a curve. I finished it with the help of my programs.

In the late 90s I had a graphing calculator that my friends and I used to link up (using the link cable) and have dueling Tetris tournaments in math class. My group were all fantastic at math, and this was an easy course, so we were acing it - thus never wanted to pay attention in class. It got so bad that our teacher told us "unless you are taking notes on them, I don't want to see your calculators out." We stowed them, having been admonished, but the next day I decided to take notes just to mess with her. She gave us the same warning, to which I smartly stowed the calculator. After class I approached her and showed her my screen. I was, in fact, taking notes on my calculator. She just pointed to the door and simply said, "get out."

Bruh. I would sit all day in math class programming games, or programming a tool that auto calculates that period's algebraic equations we were learning about. They would pass around a bin of TI-82's, so I learned how to identify the one I would always use, and sit in a place where I had a good chance to grab it. Most kids in my time (98-2001) if they purchased a TI-calc would buy the TI-83, however my mom let me splurge on a TI-86, which had a solve for x feature, basically a cheat code for that level of math in a time before showing work was mandatory. Before mario we had the game Penguinz with customizable levels. It was a glorious time to be a young programmer-hacker.

[@wavejumper3]

This video was surreal to watch. I started programming on the TI 84+ in middle school years ago, joined a few communities a few years back... The fact that someone on youtube is not only talking about this, but doing it justice... blows my mind! I'd argue a reason for their staying power with programmers is actually their lack of power. On a gaming pc, you can write terrible python code and get away with it. Calculators are one of the last systems still sold with that low of specs. All the terrible games are people used to making the PC deal with their code, and not the other way around. I'm hoping more people start talking about the history of the communities behind the code, and not just "oooooh mario on calculator download here." The lore is great, lots of twists and turns, with TI often being the villain. Thank you for making my day!

TI should re-release an unlocked TI-83 and TI-84 CE but put it in a different shell to make it obvious it's the unlocked version. It could generate some revenue, encourage programming, and make it obvious to test proctors it's unlocked. It could be a programmer oriented TI calculator designed to promote programming. It could feature a built-in code editor, compiler, and assembler. It could have a sideways or square shaped shell or come in bright neon colors.

This video randomly showed up in my recommendations and reminded me how I used to program games for casio calculators... it was a great era! Now working in the ia field, I definitly benefited from these hours spent programming on small lcd screens

[@NextNate03]

1 of the main reasons made games for the calculators back in the 90s and the 2000s is calculators are OK to have in classes. Versus cell phones, Gameboy, and other electric entertainment devices where not allowed in classes, if a teacher caughtes you with said devices, you can kiss it goodbye for the rest of the day.

It's really fun to see someone who isn't an enthusiast covering these!

[@PhilEdwardsInc]

yeah i was in awe of some of the internal calculator histories out there

[@amicaaranearum]

I remember Drug Wars! Most of the calculator games we had in the mid-90s were simple text-prompt games, but there were a few graphical games like Snake and Tetris. We primarily shared them by linking our calculators directly to each other. These games inspired me to make my own programs on the TI-83. I wasn’t very good at game design, but I did make some useful utilities for classes that allowed calculators.

[@o_sch]

For some reason the calculator to calculator direct link never worked. But I did figure out that they had a program on computers that could add files to the calculators and also manage their memory. So I would bundle programs into different "packages" that kids could ask for, connect their calculator to my computer and then drag and drop all the programs in the folder into the calculator's memory.

[@realpillboxer]

I absolutely destroyed my classmates at Tetris as you could play heads-up using a link cable. Then the Internet rolled around and I learned I wasn't shit at it, haha.

[@circuit10]

Casio calculators can run games fine if they’re written in C(++) instead of BASIC

[@jac-attack]

We had to reset our calculators for tests but one kid had a second calculator to let me get tetris back on my ti-84 lol.

[@PhilEdwardsInc]

"Hey you...come over here. OK, make sure to have a full glass of water with that..."

[@onyx.avenger]

We used the TI-86. One of my HS rivals learned TI-Basic before I did, and started making a variety of basic games with some graphics (which took forever to draw because he was using draw commands). I ended up scooping his code and revamping it, figuring out that we could store "graphs" (images) to save on load times for things that were drawn every time, and otherwise adding more features for the 2.0 release of the game. We never actually discussed this sort of thing, but we ended up leapfrogging each other as we added new innovations and redistributed our versions of the game. Now I use similar logic to build complex Excel macros to make life easier for my coworkers.

[@o_sch]

Ah, good ol TI optimization. I had this issue with my 2d minecraft i made. Blocks rendered slow enough that you could watch them draw in. At first I set each pixel one by one. Then moved to doing a "wipe" of lines which was hardly any faster. BG loading (what you referred to as the graphs) was not an option since it rendered the whole screen. Eventually I gave up using TI basic and just starting using the assembly. My calculator was too new to use the asmprgm command or whatever it was, since it was blocked out. I couldnt even install an older version of the os since that was blocked, i missed the model number by a month. Luckily it was still old enough that the command could be loaded in from online. I saved a program just with the asm command in it. Then I had to use the Z80 opcodes table to type in each hex code for the corresponding operation. Pain. Nowadays you can just use C/C++ since toolchains have been made for that.

[@davisbrown3342]

It’s videos like this that make me a fan! Well done.

[@lordrefaiv]

TI-82 user and programmer here! Wrote half a dozen simple game programs that were very popular in my school in the late 90s.

[@ishankanade5031]

I am in high school rn, and we still do this. I use a TI-nspire, which allows python code to be installed, which means I can import turtle - and honestly I feel blessed knowing that I did not go through the struggle of coding in assembly. At the same time however, its pretty wild how we see the progression of programming has translated onto graphing calculators.

[@o_sch]

The python code is not the best for games because of its size and also speed. But TI basic is also too slow. The best way to do it is use the C/C++ toolchain which converts it to Z80 ASM (for the ti84) which i wish i had when I was first writing asm to speed up my games.

[@King_Dub_Dub]

The sad part about all of this is that TI hates the calculator programming community and is always attempting to shut down ASM to prevent cheating. All it took was one stupid kid with an ancient OS on a TI-84 CE Plus and an exploit that was long since patched out and now we have OS 5.5+ ruining games for everyone on those calcs. Thankfully the community is light years ahead of TI's programmers, so there are a slew of workarounds and "jailbreaks," but it's pretty hard for a lot of people to get into calc gaming now because of the extra steps. That's worse for us because generally people who play the games try to get into making them and join the community. I worked on porting Jetpack Joyride onto the CE a few years ago, and while school keeps me from working on it I have tried to make small updates over time. People at my school who updated their OS kept coming to me asking why it didn't work anymore and I had to get ArTIfiCE installed for everyone. TI screwed us all over for a PR save disguised as a "security update" and vilified us all in the process.

[@Jaob994]

We had Casio calculators. Those really restriced ones nobody was bothering to make games for. Still proud of myself for making a kinda top down based doom clone with 3 levels and somewhat of an enemy "AI"

[@PhilEdwardsInc]

dang!!

[@fredericdesautels1026]

Good stuff! I think one of the big reasons high schoolers are still programming their calculators despite having access to phones/computers is because of how accessible it is. You don't need an IDE or a compiler or anything, you just tap the PRGM button and start typing. Plus you can do it in the middle of a class, which happens to be when you're the most bored ;) For me, its also what got me interested in computer science and pushed me to go down that path. 10 years later, still doing calculator stuff but now with a comp sci degree!

[@PhilEdwardsInc]

that's a good point.

[@cresswga]

I am a few years too old to have been able to get into this. I think I had a TI-81 which only had enough memory to program a quadratic equation solver. Mostly I used it for coming up with trigonometric formulae that drew pretty pictures on the graph screen when you plotted them. We were always threatened with resets for exams but it was either too much trouble or the teachers knew there wasn't enough memory for us to gain much advantage; especially when so many points were awarded for showing your working, not just getting the correct answer.

[@EstTheSword]

Well when the school puts immediate suspension for the sight of a phone, I bought a TI-84 Plus CE so I could play pokemon.

[@jonp8225]

I programmed calculator games for my friends and I to play in high school. I would spend most of study hall everyday in 10th grade coding it. I eventually had a pretty large RPG with equipment, towns that could be entered with shops and random battles. Basically a small Dragon Quest game on my TI-86. Our teachers would make us show them us clearing the memory on our calculators before tests, so my friend and I wrote a program that mimicked the reset process so our games wouldn’t be deleted. Sadly I lost my games when the memory backup battery and regular batteries died at the same time. I currently work as a software engineer. Programming my calculator was a huge part of me getting into programming.

[@southbridgeforestHOA]

I remember my first year of college 1994, TI-85 came out with a data link cable that let one type on a computer and then save those notes to a program in the calculator. It was a game changer that let one easily store notes in the calculator. Other students were typing in notes using the calculator's number buttons which was super slow and tedious requiring multiple presses of the same button.

[@patch6306]

Great video! But I think there is an important thing to add as we look to the future. Desmos is far, far more than a simple calculator emulator; it is more like the next step in the evolution of math education. It is much faster than the TI calculators at nearly every single feature. It is in full color, while most TI models are still stuck in black and white. And it's a free service, unlike the TI calculators which are locked behind a $100 price tag. In fact there are secure versions of the software that will (likely) be allowed on the SAT in the next couple of years. It's really only a matter of time until it totally supplants the TI calculators for things like standardized tests.

[@PhilEdwardsInc]

i'm glad there's some movement forward!

[@Kylefassbinderful]

One thing to know is that Assembly programming hasn't always been encouraged on TI hardware. TI has tried blocking it for years but the community has always caught up. The newer models aren't as easy to code on as the older 90s models.

[@dewit5883]

I remember when I had geometry dash on the ti-84 color in 6th grade and everyone would give me jolly ranchers to use it for the period

[@stischer47]

1980, my school got six TRS-80 Model III computers (16K of memory, tape recorder memory). No one wanted them and I said, "Yes" because they looked cool. I set them up in my inner-city 5th grade class, learned BASIC, taught it to the first group of students, then turned the machines over to them to run and maintain. It was amazing what they came up with and gave them control of a new technology. And it started me on my journey to getting a PhD in Computer Science with a focus on Artificial Intelligence. Any new technology can be used...or abused.

[@GorilieVR]

5:00 identical to the war against ChatGPT/Ai. Educators always fight change -which is particularly problematic in the west. Since what we're doing is objectively not working, perhaps we should consider leveraging Ai and see if scores improve (they will).

[@TheLastMillennial]

Great video, it was fun to watch! I got into software engineering due to programming my calculator. It's a shame TI is cracking down on fun programming by disabling assembly programming on the TI-84 Plus CE (although there's a jailbreak to bring it back) and implementing Python in a way that force the programs to pause and wait for key presses. On the bright side, these restrictions got me interested in hacking! I've been messing around with graphing calculators for 7 years now so if you have any questions about them, I'm more than happy to help!

[@AndrewPatterson3001]

As a student I was one of the kids playing games on TI-83 Plus and later TI-92 during math class.. Later after I became a math teacher the devices were still in the classroom (TI-84). My students couldn’t afford them, so we had a classroom set. I tried letting students take them home, but parents would sometimes pawn them off. The TI calculators have so many functions that are rarely used in class. They’re remarkable devices, but I have to admit I think they’re no longer the best tool. Desmos is just as powerful and free! I completed the Circle and now I write math education software. I do think that giving students a chance to explore technology on their own is very important.

[@FlameMage2]

I used to love programming math tools and converters for my TI-83+ Silver Edition! I had a Casio graphic calc before the TI and it was rough to use but I delved into it because it was all I had for a while. Loads of gaming as well, trying to get the link cable to work with the software was really tough though, freezes and hang-ups and corrupted data. Then I got a Palm V and tried to overclock it so I could run a gameboy emulator. Long story short I ended up getting a TI calculator emulator, and then eventually saw Wolfram Alpha and was like ohhhh, game over man. I don't need this hardware ever again. Shout out to Texas Instruments for keeping their ancient obsolete calculator tech absurdly expensive throughout the years!!! Great video Phil!

[@dlsspy]

Yeah, I got an HP48GX shortly after they came out and couldn't understand why everyone was so interested in the TI calculators which were behind in every conceivable way. But like a lot of people mentioned, I learned so much programming on mine. RPL and lots of Saturn assembler. Seemed to take everyone else decades to catch up to what my high school calculator could do.

[@cberge8]

Learning to make games for my ti83 back in 1998 is what spurred my interest in coding in general. Ultimately it lead to pursuing a compsci degree.

I bought myself a TI-86 in my first year in high school, and also got the GraphLink cable so I could download stuff to it from the Internet. Although I did not play games in class, I spent many lunch periods trying to get the highest score I could in Tetris (I was the outcast nerdy kid, so having friends wasn't a thing) although later the link port broke so no more "deals" on the bus after school. In Pre-calc class, we had a teacher who knew that everyone was playing games on their calculators, but did little to stop it - "All you guys do is play games when you should be learning". In my senior year, I was in Calc BC, we were all issued TI-89s and that was a nice calculator, as it had a nicer display and could even solve integrals.
