LGR – “Doom” on a Calculator! [Ti-83 Plus Games Tutorial]

Just call me a cold, calculated killer. [typing]
[DOOM theme plays] Greetings and welcome to an LGR thing, and, yes, we’re gonna be playing Doom on one of these! One of these! This is a Texas Instruments TI-83 Plus graphing calculator. Released… way too long ago and still costs too freakin’ much! Unless you’re like me and recently
found one for $5 at a Goodwill. And, uh… [sliding plastic sound] That is still such a satisfying feeling.
[case clasps shut] Hahhh… You know, I’ve talked crap about
Texas Instruments before, and sort of analyzed their business practices, and why these things still cost so much and are enforced in so many schools. But today, I just wanna talk about them in a rather happy sense because these– they’re really cool, as far as the hardware. If you can get one for cheap. Yeah, back in the day when I put software on here, we called it “hacking.” It wasn’t– [laughs] ’cause we were stupid kids and hacking sounded cool because “The Matrix.” This is actually a thing that
Texas Instruments wants you to do. Not just math. They built in the functionality
to install your own programs using a cable that *they* provide. Let’s just go ahead and take a look at this because I think this is super fascinating, and DOOM! So pretty much the only thing you’re going to need, other than the calculator and a “computor,” is one of these Texas Instruments Graph Link cables. This is the USB edition. The one I had back in the day I think was serial. But yeah, they make them in USB now,
and they work, like, the same. And they’re just obviously easier too, uh, get working on modern hardware. So it has this little, uh, analog-looking jack, I guess. And you plug that right here
into the bottom of the calculator. And then just turn it on. Plug this into your computer and… go into the software which is at this point called TI Connect. That is the version for modern operating systems. There’s some older ones as well. Like, if you really wanna do this on a
Windows 95 computer, you could. So, yeah, you just start it up,
it will detect your calculator. Who knows? Just browse around. If you’ve got a used calculator, you might
have some stuff already pre-installed on there. Could be interesting. But anyway, All you gotta do is go over to a website like ticalc. There’s links to all this stuff in the
video description, by the way, but yeah. And just find a game that is
compatible with your calculator. In this case, we’re looking for the TI-83 Plus. Download what you want, extract it, and you’re gonna be looking for one
of these either .8xg files or .8xp files in the case of the 83 Plus here. And you can pretty much just
drag them onto this window. Or with the .8xp files, you can right-click them, at least in Windows, and have
it send it directly over there. Really, just check the instructions
for whatever you’re downloading. It’s probably in a .zip archive
and it’ll tell you how to do it. Some things are gonna be different. Yeah, for the most part,
it’s just drag-and-drop, and that’s… pretty much it. The only other thing to really worry about is
sometimes you’re gonna need a kind of loader program. The two that are gonna be the
most poplar are Ion and MirageOS. These are programs that you’re gonna run before running, like, the other
programs that you wanna run. Considering a lot of games require these, they’re good to have both installed on your Texas Instruments device. It’s also worth noting you probably
wanna upgrade your operating system. I have version 1.19 on my TI-83 Plus, which I think is the most recent version. And it’s free. All this stuff is just
still on the Texas Instruments site. They support this crap because,
I mean, they friggin’ still sell them. Okay, now that I’ve got some software
on there, I’m gonna go ahead and turn it on, which just brings us to the normal cursor
there, which, uh, you know, let’s just do calculator-y things and whatnot. But who really cares? What we really wanna do here
is check out what’s installed. And, you know, make sure everything’s good. So, press the 2nd button here and then MEM right down there, which brings us to this menu. And this’ll let us check what
is actually in the storage here. Its… massive 160K of flash ROM, and 27K of RAM. You can see we have some RAM in the archive free there. The archive is the flash ROM. And, um, if we go and check here… You see those little things with
the asterisks to the left of them? That means that those are archived. Those are programs and apps and, you know, whatever. So… if it’s archived, that means we’re
not gonna be able to open it directly. And in fact, a lot of these aren’t gonna be
opened directly anyway because they’re you know, coded in one way or another. So that’s what those external programs
that I installed on here was for. Such as MirageOS, and I just press
the APPS key to open that up. And this right here gives us a
nice, little graphical interface that shows the things that it
thinks that it can open. [chuckles] Some of them it can, some of them it can’t. And for those that it can’t, then that is actually going to be… uh, opened by pressing “Program” here. And that “A” at the very top, that is Ion. You see these other Ions? You open this
one first, once you transfer them over. It’ll install this “A,” and that’s when you open this. You just put in the “prgmA” command. And this gives you another little menu. It’s just all text. And these are the things
that it can open from here. So, let me just go ahead and open Tetris first because you know, it’s a very simple thing that you’d probably expect, maybe, that this could do, but even still, I think it’s, um, pretty, pretty fascinating. You just use the arrows and it’s, it’s friggin’ Tetris. And it works, man. Obviously, there’s no sound on this because it’s… it’s a calculator. But… If it had sound, I imagine it would sound, uh, very calculating, perhaps mathematical. Alright, so I did something wrong there. Sometimes you’ll get some weird errors like that,
but just clear out of there, and, um, [chuckles] hopefully we’ll be okay. Uh, let’s open JezzBall. You do have to be kind of careful with this because, um, just the memory of this system is… you know, I mean, it’s insanely lacking. The fact that it’s pulling off this stuff at all is just kind of amazing to me. But, yeah, this is a version of JezzBall. And as you can see here,
it’s kinda like the arcade game Qix. And if you played, uh, you know, any of the good Microsoft Entertainment Packs
for Windows 3 back in the day, yeah, pretty much… probably recognize this. Just try to… Oh! That didn’t take long at all. You try to trap the balls. Dang it! Let’s try Super Mario 1.2 here.
This I’ve always found impressive. This is another one that I had back in the day, and holy crap. I don’t think it was maybe 1.2,
maybe it was an earlier one, but… This is just darned impressive to me. It’s, um, again, also really tough. [chuckles] Because of, you know, I mean, it’s just… this little screen. But it’s a fully featured Mario game. Holy crap. It’s just–it’s not only really fast… Like, impressively fast. I don’t know if
they were just trying to show off or what, because it makes it really hard to play, but, uh, yeah. I mean, it’s pretty awesome, actually. Yeah, time for the main event here. And that is… zDoom. There’s actually another version of Doom on here,
believe it or not. There’s two of them. But this is the one that I find to be,
well, just the better one. And it is actually based on this other one
that a lot of people call it “French Doom.” This is the other version of Doom
I was talking about, “French Doom,” that is was based on, like Doom 83. It was just made for the plain old TI-83. And, honestly, while this is impressive in its own right, it actually shares more in common with Wolfenstein 3D. I mean, you can see I’ve got like you know, the gun from
Wolfenstein right there and… It’s pretty fast is the thing. Like, it– It’s a more than playable thing. But, uh, it’s… whoop! “Perdu!” I died! Yup, that’s it! It just kicked me out. So you can kinda see what that was.
It was just pretty much Wolfenstein 3D, but they called it Doom. I dunno. But this one, on the other hand… So you can actually go over here into the options, check the difficulty, which is– I’m gonna put it all the way down
because this is a really tough game. And we’re gonna start a new
game here of zDoom 0.12. Level 1. And, yeah, you can see here, this, I think… screams Doom. Even though it’s still, you know, the same kind of… there’s no, like… height difference in the levels,
it’s just very Wolfenstein-like. And as you’ll see, it’s a lot slower And that’s probably due to, like, the animations here. I mean, look how slow I’m shooting! Holy nuts! Yeah, there you go. Die! At the same time, I’m playing Doom on a calculator. [chuckles] And that right there is just, uh…
I mean it doesn’t matter how slow it runs, to me. Considering how old this hardware is in here. I mean, we’re talking insanely limited z80 CPU kind of stuff. 6 MHz, I believe. The fact that this is even doing
anything at all remotely looking like Doom is just fantastic. It’s just, uh, almost unplayable. You–this is all it is, by the way– You get some weapons later on, if you can survive, but I mean it’s just so slow that it’s unbearable, really, which is a shame. Uh, so that’s, that’s Doom. [laughs] That’s all I gotta say! Um, pretty much if you wanna mess
around with one of these calculators, then why don’t you do that?
I mean, pick one up. It’s super limited, but I mean
there are a ton of games. And as you saw, I mean, it’s pretty simple to get them on here. Not a big deal whatsoever. Oh, sweet! Got to Level 2. Nice! But, yeah, once you figure out these
thing’s quirks, it’s awesome. And I am dead. [laughs] Well, that’s pretty much it for me messing around with
some gaming on the Texas Instruments TI-83 Plus. I mean, holy crap. What a cool little thing. And it was like never meant
to be able to do stuff like that. Um… That’s just… that’s what it is. Bloody fantastic, as far as I’m concerned. And if you enjoyed this little look
at some weird stuff on a calculator, then perhaps you’d like to see some
of my other videos on calculators and other nonsense. I’ve got new videos every
Monday and Friday here on LGR. So, check ’em out if you’d like. And as always, thank you very much for watching.

  1. look at what I did: https://studio.code.org/projects/dance/Qo_Eh46x2GKMrqewFvMVIqg3qvLSFmP6yk-tr4GYN-I
    hit space then enter than a than up

  2. Actually some calculator has sound output. the Casio FX-CG10/CG20 for example you can actually get sound output albeit a crappy quality. I gave my CG20 to my friend and he turned it into a GBC emulator in the class when he's bored lmao.

  3. I remember in middle school when we were first expected to have one of these calculators. You could borrow a TI-82 from the school, but many of the kids brought their own TI-83. Lots of games being passed around between those with the same model. Except for me – my dear mother found a TI-85 on ebay for $30 and believed she was getting a great deal, since it's a bigger number, it has to be a newer model! Well it wasn't because the TI naming scheme is weird, and I used that thing all through high school and up to college.

    I must say it got me into coding though. Whenever there was a program needed for the class, while everyone was copying it between themselves, I was sitting there looking at the TI-BASIC code on a 82 or 83 trying to frantically rewrite it into the 85's dialect.

  4. Let‘s do a Video on a Calculator about Playing Doom on a Printer-Display an lets watch the Video on a Casio-Digital-Clock in Minecraft !!!!

  5. A whole generation of students have just failed their maths exam…. Feeling guitly yet? 😀 Just joking, chief 🙂

  6. That moment when you are in a commercial plane and near you an old geek will takes out his pocket calculator and instead of calculating accountancy, is starting playing doom

  7. Man I miss my days of ti basic programming. Never got any further than learning to program falling pixel or snake. But I could do it perfectly without instructions after a while.

  8. I'm late to the party but the random characters you had on screen were from the memory running , it dumped your Launcher from memory, then couldn't read the Tetris game. The Mario game is sped up because of programming sucks for platformers.

  9. These are $100+ from retail you can get them off people that used them for school and are sitting in a box somewhere for $3-$22 it is big lol

  10. Low spec gamer did something like this but with a more upgraded calculator it was still Texas instrument but it had color this time

  11. Это впечаляюще! Спасибо. Кстати, некогда такие же фокусы проделывали с черно-белыми телефонами марки sony. В частности, у меня был sony j70, я его прошивал специальным самодельным кабелем с дополнительным питанием и устанавливал потом приложения, в частности игры, такие как шахматы и даже похожий 3-д шутер. К сожалению теперь уже вряд ли можно найти в сети следы этого программного обеспечения и схемы кабеля

  12. It's priced like everything else on the market. There is a limited number of calculators manufactured and a high demand for them. Creating a high price point. Economics 101.

  13. I already have a hard enough time in math class, now my ass is gonna take this college algebra class a third time because I'm playing Doom

  14. I was like 16 when I got one of these maybe even 14 my first year in high school I had the cable to hook up to my friend's calculator
