[@obsoletegeek]

My math teacher circa 1995 "You won't always have a calculator available to you!" Stick it in your eye, teacher.

[@frankschneider6156]

+The Obsolete Geek You won't always have a smart phone with sufficient battery left with you ..

[@frankschneider6156]

Nukle0n What's next ? You wanna tell me that you also don't need to learn how to make a hand axe for being able to hunt mammoths or your neighbor's dachshund when hungry ?

[@CommodoreFan64]

+Frank Schneider You will if you keep a couple of battery banks charged up, and your like me, and keep them in your daily backpack. Also I have a Moto G3 2015 I pulled off my charger this morning at 7:30 AM eastern time, and it's now 2:20 pm eastern time, and I still have 93% battery life left. So newer smartphones have gotten way better on battery life for sure.

[@frankschneider6156]

Commodorefan64 I prefer to use my private phone just for calls, so I use a rater old phone. Therefore charge lasts (depending on cal frequency of course) around 2 weeks.

[@CommodoreFan64]

Frank Schneider I'm not sure if you are in the US, but if you are, and have a GSM phone on an AT&T tower that's only using 2G you will be forced to upgrade at some point because AT&T is slowly shutting down 2G to make way for more 3G and 4G LTE . Same with T-Mobile if I remember correctly.

[@Kiralitess]

Even thought I was born in 1985, after the bulk of the war occurred, I saw the after effects as a kid. Even though basic scientific calculators don't offer much in the way of entertainment, I was fascinated by them as a kid, and because of said war, it always seemed like each person had a different one. I just loved tapping away on the buttons, even though I wasn't in true need of a calculator. I never knew graphing calculators existed until my brother was well into high school and got one. He barely ever let me look at it, but when I entered high school and he got a new one, he passed his old TI-86 graphing calculator to me. The fun part about it was that I rarely used it to calculate or do graphs for homework. You see we of course weren't allowed to have handheld gaming devices out while in school, but my graphing calculator got around that. So while in study hall, I would turn on my graphing calculator and play crude but still fun versions of either Tetris or Super Mario Bros. I also ended up programming funny little fortune telling program that had over 100 different fortunes to hand out depending on what number the player chose. Of course when I was really bored, I would input various graph equations and then press enter, which layer all the graphs of the equations in such a way to make intricate drawings/designs. I don't know where it is now. It is very distinct though, as back when I was a sophomore in high school a friend of mine stole it for a class period and covered it in forest camouflage duct tape.

[@zoeymyu4954]

I hope you find that calculator

[@LobotomyballZ]

You have reached your limit on talking, shut up

[@AmesiesCorner]

Man, I remember when anything with a digital display was sci fi. The fits that where thrown when a watch with a digital display came out. Then the whole calculator watches came out..

[@AmesiesCorner]

+Amesie's Automotive Corner I feel old now..

[@fununclenerfs]

Can wait to see a version of this video about Smartphones in a decade or so

[@payhemseht]

+fununcle "Most people do these things using their glasses, but there was a time where you needed a thing called 'a smartphone' to do them"

[@payhemseht]

***** it was nothing like what we thought it would be... I'm having high hopes for Microsoft's "HoloLens", though

[@zyzril]

+Sergiu Pop I'm still waiting on my neural interface. Pffft people used to do things with their hands? with their eyes? Hold on I need to download myself into my drone.

[@ukrainiansturgeon8561]

Apple is basically Ti and Samsung is Casio. Every other cheap graphing calculator is a cheap fake samsung phone.

[@MrAmomaxia]

Top ten calculator waifus

[@osaelokailodibia1307]

I agree

[@Ampera_]

HP Calculators have another interesting feature. All of them used Reverse Polish Notation instead of Algebraic notation for all calculations. This meant that the numbers being calculated were entered into a stack and then the operator was given. I.E. 5 ENTER 3 ENTER * =15 As a result calculations could be executed in massive chains and done much quicker then calculators by Ti, and this really shined in their graphing calculators with 64 bit-ish saturn chips that used nybble data and some other weird 20 bit shit that made it run faster then most Z80 solutions at the time. I have an HP48G with like 640KB of memory. It's a GREAT calculator, and it can do mathematical operations in a snap.

[@irides46]

Love these. Plus RPN basically makes order of operations a natural process. Used the HP calculators since my first, TI calculators always seemed backwards and slow, HP's Saturn and ARM based units ran leagues faster and could easily be programmed in straight C! TI's piddly little crap seemed amateur in comparison.

[@Blustride]

Communist Ralph Most, not all, HP calculators use RPN. I've got a 22S circa 1987 that just uses regular notation. That said, I do like RPN a lot. I need to grab a 48GX some time. More numbers more better.

[@38911bytefree]

A bit annoying first .... brilliant once you got used to. In my 48G+ (128K RAM ... WOWWWWWWWWWww). But seriously .... what a machine.

[@ghostunix731]

Yes but went they started making full fledged computers 🙄 Like seriously HP has not changed at all.

[@memes_jack]

Your voice really fits the "history of" type of content. Really easy to listen to and interesting. Keep up the good work.

[@robertwhitley6233]

The calculator wars.So many lives lost,so much destruction.

[@CarlosFernandez-qz7mf]

Robert Whitley my grandfather died during the calculator war in 1978 :(

[@rtxon6031]

They couldn't even calculate the costs

[@ottohahn-herrera8618]

Only the dead have seen the end of the calculator wars...

[@scythal]

The destruction caused by the Cold War will never match the destruction caused by the Calculator Wars!

[@JLajos]

Wait, I need some time to process this.

[@TheEPROM9]

This is why I love vintage calculators, they were a real forerunner of technological development over the 60s and 70s.

[@DrAnimePhD]

I swear, everytime LGR posts a new video, extreme comfort soon follows.

[@SteveBenway]

Back when I was in school, *many* years ago, everyone and their dog had the Casio fx-82, while I was utterly unfashionable, with a Texas Instruments TI-30. How the other kids laughed, with their fancy LCD displays, when I couldn't see my LED readout on a sunny day.

[@zyrgle]

+Steve Benway (Retro Gaming Collector) We need a video of that... not a run-through, play-through, or anything like that... just you, using the calculator badly.... :D

[@SteveBenway]

Sadly, I don't have it any more.

[@dubsy1026]

Steve Benway still have an fx 82. it was actually my father's and I still use it

[@BLACKCHALLENGER57]

I have a working TI-30

[@Windowsfan100]

*MANY* years later, the Casio FX82 still remains the norm for Dutch high schools (we have the fx-82MS as standard here)

[@wlsn5916]

i never knew a video about calculators could be so interesting. Only LGR could do it.

[@Boemel]

I still have a mechanical calculator from 1918. Gift from my grandfather. Weighs a ton and can only add up numbers, that's it :D

[@auradieguez6013]

Ha ha ha ha

[@Powerhouse1]

Glad to see the first episode of Tech Tales for 2016. Just like everything, innovation weeds out the companies that cannot compete while the strong ones live on for years to come. it's the same reason why there are only a handful of companies making consoles. It's also very interesting to note how calculators are the reason why computers still exist. It is often a forgotten topic, and I'm glad you touched upon it.

[@afgncaapthegreat2706]

> implying that the console market is innovative

[@Powerhouse1]

AFGNCAAP the great As in more features being added. Believe it or not, consoles have grown over the past few decades not in terms of graphics alone, but in terms of overall features.

[@Yusuke_Denton]

+Pow3rh0use The important point there is that they must keep innovating + understand the market. Being the first to invent something doesn't guarantee longevity.

[@SeanLamb-I-Am]

I remember seeing these calculators in the 80s, and getting so excited to just play with all of the scientific functions on them. I think I got my first calculator sometime around 78 or 79, when I got to fifth grade. I also got my dad's old slide rule at that time and learned how to use it. In middle school (about 1982) I had a couple calculator watches too. The real cool nerds all got HP calculators and extolled the virtues of Reverse Polish Notation for making their computations. But it was extra special for me around 1985 when I was able to purchase my own scientific calculator, a Casio FX-451 for about $25, that is still sitting (and still works) next to my desktop computer. All of the scientific functions were placed on membrane keys on the calculator case. There's a photo of one at Calculator.org.

[@MiguelAbd]

Since I'm a 90s kid I've never heard of this war but it was amazing indeed. I just wonder how my grandparents feel seeing the world go through the calculator wars but today having an smartphone. It must be overwhelming to think about it!

[@nwawallace]

YAY! I was hopeing tech tales wasn't a dead series. As much as I love all of your content, these always fascinate me the most. Probably takes quite a bit of work too, so thanks for all you do man. It means a lot!

[@DergEnterprises]

For Calculus 2 (years ago), I bought the TI-Nspire CAS. Wow, the plethora of ways to add 2+2, and in color! Actually, it will draw a 3-D model and rotate it.

[@AdamBolton1]

These videos are just great, and I don't know anyone else doing this kind of documentary style video about these topics. Awesome work, man.

[@Novabug]

That was surprisingly interesting. It all makes perfect sense too, the calculator evolved like most tech. Good work LGR.

[@Rovaniemiplayer]

Great stuff! You find dozens of videos on Atari history, Magnavox and similar topics of computer and gaming history but your uploads gives some competently assembled insight into tech that has hardly any coverage elsewhere.

[@xChillDudex]

I would love to see a follow up video on this. Also would love to see a spin off tech tales about the console wars or even the video game crash of 1983. Also you are seriously one of my favorite youtube channels, you make great videos and I love every one. Not to mention you are active in your comment community even with videos that are older.

[@LGR]

Thank you! I'd like to cover the crash of '83 at some point :)

[@liammontgomery1825]

I showed this video to my dad, who was an engineer around this time period. He and his buds used to get together with their calculators and have calculator races. They would input complex equations and see whose was the fastest.

[@LGR]

That's awesome, I hope he enjoyed!

[@sventobergte845]

The Dankpod army comes over here! Hello Clint!

[@brandonb3279]

I absolutely love your Tech Tales videos. I realise these probably take the most work in terms of research and production, but I hope that you are able to keep putting out more videos of this nature and quality. Thank you so much!

[@LGR]

Glad you enjoyed!

[@bartdunbar5108]

well done! I love classic portable calculators. one of your best videos so far. happy new year

[@mrpositronia]

Calculators were up there with Speak and Spell, Game and Watch, and Tomy 3D games, when I was in primary school. That soon went out the window when we started getting home computers like the ZX Spectrum and the C64.

[@frankschneider6156]

+mrpositronia The speak and spell was not only a great and an icon of today's pop culture, but is still used by some in the music industry (see circuit bending, although they thereby somewhat destroy the poor thing).

[@ThomasSpychalski]

+Frank Schneider Really?? Have to look that up.

[@frankschneider6156]

Thomas Spychalski The Wikipedia article on Speak & Spell has 2 sections and references on this topic for a start.

[@ThomasSpychalski]

Frank Schneider Cheers!! :)

[@JeFi2]

Those desktop calculators are freakin sexy! If I had one I would totally look at it once in a while.

[@Locut0s]

I absolutely love this series of yours. It's really something unique and special you have here on YT! I love all your vids actually, but this series especially! Keep it up.

[@ryanamberger]

Heck yea. Been waiting for a new Tech Tales. Awesome start to the new year!

[@BlackburnBigdragon]

Wow! I didn't realize that there was a time in my life when consumer calculators cost $1000! It's amazing the things you don't think about when you live your life not thinking about the technology that whizzes past you in your lifetime. I seem to remember there always being calculators around but I was very young then. Apparently, there was a time in my life when my parents would probably have been doing all their math with a slide rule or the long way on paper.

[@mroxannevh]

My senior year in college I took a history of computing/social media course and she DID NOT discuss calculators AT ALL. But that was years ago. You should be a professor LGR!!!

[@TheSolidPlaya]

awesome video clint, I can't believe calculators played such a huge role in the making of pc's, which lead to the future of technology and science, including SNES consoles, super compact and powerful laptops. Gsync, and OLED displays.. in only a short span of 50 years.

[@FelixG]

Very articulate and interesting. Tech Tales is probably my favorite series on your channel, really great to see a new one.

[@buttholebandit3815]

Clint you just made me care about calculators, well played sir. I would love to see more on this subject

[@Thematt11]

You know if you collated these episodes into a Tech Tales book and included some extra non-video content like scans of articles, interesting stuff from manuals etc I'd totally buy it and I'm sure would many many other people.

[@TheLORDMJ]

What an interesting episode. I didn't know that calculators were so involved in the computer revolution. I always enjoy Tech Tales. They are very well presented and you always manage to dig up very interesting stories. Can't wait to see the next one.

[@roe9908]

another great tech tales episode, I love this series and really appreciate everything you do on your channel, keep up the good work

[@banjoguyollie]

Oh man , that brings me back to school and wanting a ti81 so bad. That thing was like the coolest thing ever at the time :D

[@GentleHeretic]

Do you happen to know anything about a device called the Little Professor by Texas Instruments? My grandparents have had one since the 70's (I think, could have been later in a thrift store), and they also had an activity book that (I believe) was sold separately. It's just that I've always been curious about it, seeing as it was used as a "replacement" for a handheld game system when I was younger.

[@TschimmiCash]

Oh! I had to learn math with one!

[@thefivespokewheels]

numberphile has a good video on it

[@ShadowWingTronix]

It was more of a math teaching game than a calculator. I still have mine around here somewhere.

[@protistman]

I love your Tech Tales videos and this is another great episode. Thanks for making them and please keep 'em coming!

[@jmfa57]

Ah, memories! I had a Texas Instruments SR-10 in high school, and Dad migrated from his beloved Kueffel und Esser slide rule to a Texas Instruments SR-50 shortly thereafter. In college I switched over to Hewlett Packard and RPN notation and never looked back. Great video!

[@michaelboyars7534]

I would like to hear about TIs dominance in the educational market.. I still have my IT 82 plus

[@JORGETECHJorge]

I wonder if you could do a Tech Tales about LCD handled games.

[@LGR]

Perhaps! I covered them a little bit here already too: kzbin.info/www/bejne/lXqpdniEbMqjZ6M

[@JORGETECHJorge]

+GreyWolfLeaderTW I still have my Nintendo Mini Classics Super Mario Bros, I play it since I was very young and I have a Brick Game a Tetris low cost clone. I think I had more but I don't have them now.

[@PashPaw]

Thank you. IMHO, pocket calculators are still awesome since there is something about how they look and feel that I prefer over a cell phone. And a computer is still a calculator at heart. It's fun to see people's reactions when I'm using a early 1980s HP-11c calculator though.

[@manuelarturog]

Great video LGR! keep those tech tales coming.

[@slitor]

Have you done a bit about BBS's yet?

[@Jorendo]

I remember the end of the 90's begining of the 00's, i was in highschool and here in the netherlands you have different degreees at highschool. I had to get me a calculator too, a Casio, it look pretty, you felt cool to have one...even though it didn't do more then calculating stuff. Then i made friends in a higher degree at highschool and they got these advanced calculators that could play games like snake on them.....They needed them cause those machines could do some extra calculating stuff my casio couldn't do..lucky bastards...try to explain to your parents you really need a 150 euro (back then guldens, we switched coin) costing calculator when you can get a cheaper model. Atleast they had too by school regulation. What a time that was. Now you play 3d games on your phone....my highschool me would never believe that.

[@raxigar9176]

I think this is becoming one of my favorite series of yours.

[@larryinc64]

Another fantastic video, This is what I love from your channel, videos on topics i never thought or knew about. With how popular retro console gaming is, old computers seem to not be talked about as much.

[@austoful]

honestly a good scientific calculator is still very necessary for school and research work.

[@SKMCTV]

What bout typing 80085 to spell "boobs"? How did you leave that out?

[@vwestlife]

Or 0.7734 to spell "hello" upside down.

[@Kiralitess]

+SKMCTV I'm guessing you didn't watch to the very end of the video?

[@StarLiteNL]

he didn't, it were his very last line at the last 2 seconds of the video ;)

[@Kiralitess]

Elwin van der Meer Well he did. Yeah, he didn't type it out, but saying it at the end is a nod to it so, it is the same.

[@maxking235]

""No heaven? But where do all the calculators go?"

Wow. This was amazing. I knew some of the pocket calculator history but not all, really nothing compared to me knowing so much right now. Thank you Clint, keep it up!

[@SpaceKingDinosaur]

Who'd have thought the pocket calculator history would be so fascinating? Great work and many thanks for making it.

[@blackfalcondown580]

I still rock a Casio scientific calculator, screw phones.

[@diablothe2nd]

Oh wow! I had that very same Casio FX 7000G at school! I actually tried looking for it a few months ago and couldn't quite remember which model and there it is at 7:37. You just gave me a blast from the past haha! Thank you

[@GarryChenYT]

Sony was like "Who wants to use the calculator and computer anyway ?" Jokes on them lmao

[@McRocket]

Interesting and well presented (imo) review. BTW, there were hand held calculators years before these little electronic babies came about... en.wikipedia.org/wiki/Curta

[@LGR]

I had a section in this video about Curta, but cut it due to wanting to keep more focused on the 70's calculator war.

[@BlaMurda]

So happy you did a new Tech Tales! Thank you.

[@X-OR_]

This was great. I Still have Two Model 600 National Semiconductor calculators (6 digit.4 function and no D.P.)

[@kniferaffe]

why was this so fascinating?

[@LGR]

Making it fascinating was a calculated move on my part. It really adds up, huh?

[@ChaplainDMK]

+Lazy Game Reviews That was just painful

[@joshnixon1998]

God damn it LGR, you're the only person who can make calculators this interesting.

[@Measuring0Cups]

I like this. Talk techy to me.

[@slashtiger1]

Been hard at work adding Dutch subs to this vid for a friend of mine. They've been approved and are now public. As a result, I've just now watched this video for, like, 25 times, if you include the retakes that were necessary to align the subs to the sound. Interesting little insight in history! Keep this stuff coming!

[@raptorbandito]

I wouldn't have expected that topic to be fascinating but it was. Well done!

[@Roverd26]

LGR, I know that earlier Pentium CPUs had issues with floating point calculations. Did earlier (or cheap) calculators using chips have similar problems with accuracy?

[@Damaniel3]

+Roverd26 The biggest problem is that some operations took a lot longer to complete than others, even when using the same operator (the square root function was notorious for this) - some combinations of numbers would calculate instantly, other combinations would take a few seconds. However, there were also a few inaccuracy issues with operations like square roots in some of the earliest calculators that supported them (there was one buggy calculator-on-a-chip type from early on), but the errors generally weren't all that huge.

[@vwestlife]

+Roverd26 Calculators and computers have always had computational quirks and limited precision, but these were well-known and disclosed to programmers and users. The reason why the Pentium FDIV bug became a scandal was because Intel tried to keep it a secret, and even after it became known, they insisted that it wasn't a serious problem and that the average user would never be affected by it. Intel was actually correct, as the chance of the error occuring in normal use was extremely rare, but once the story hit the mainstream news, the PR fallout was huge and Intel ultimately agreed to recall and replace all the affected Pentium chips.

[@themaritimegirl]

+Roverd26 All calculators have limited precision, and it will be different for each calculator. A neat way to demonstrate it is to calculate arcsin(arccos(arctan(tan(cos(sin(9)))))). The answer is 9, but different calculators will produce results of varying accuracy, and earlier calculators are indeed worse. Of the calculators I have here on hand, the best is a Casio FX-991MS with 9.000000007 (even my $160 TI-84 Plus CE is worse), and the worst is a circa 1978 HP-33E with 9.0004. I've seen only computers and cell phones reproduce the exact answer.

[@JsbWalker]

+themaritimeman Just tried it. I got 9.

[@themaritimegirl]

+James Walker What's your calculator?

[@guyball8469]

This was a great video. You've done a great job of summarizing the calculator wars & history during the 60s and 70s. Do you have a copy of our book, Collector's Guide to Pocket Calculators, www.amazon.com/Collectors-Guide-Pocket-Calculators-Bruce/dp/1888840145? I'll be happy to drop a copy in the mail to you.

[@LGR]

I do not, but that looks great!

[@theretrogamer7779]

Guy Ball how much is it?

[@guyball8469]

Normally through amazon, it's $20 plus $4 for US mailing.

[@technopoptart]

gotta love the fact that even the arguments on this particular video are fairly wholesome X'''D

[@freequest]

I have a Sharp ELSI MATE EL-5001 that dad bought many many years ago still runs well and use it in the shop love the Green display on it.

[@Dreadjaws]

$25000 for a freaking calculator? I'm never gonna complain again about the price of high-end graphic cards.

[@ZaneBlade88]

Dude go get a teaching degree and teach tech history.

[@LGR]

I'm quite happy to teach on the internet for free and reach millions, instead of in a small room to dozens, but thank you :)

[@radarlockeify]

Ooh, the Casio fx19.... I got shivers! Takes me right back! Great video!

[@1NSHAME]

This video and the Texas instruments one is how I found out about your channel. Two years ago maybe? Since then I'm watching all your videos one by one in chronological order and I just reached this video again! I'll finish them! Thought I'm skipping most thrifts and let's plays for now. But all your videos are lovely. I can't point to a single thing to change really.

[@KitJohanson]

This is easily one of my favorite Tech Tales episodes, because this really ISN'T a subject anyone brings up at all. It's also one of the things I point to when I talk about the quality of this channel. :)

[@xebek]

This is neither Lazy, nor about Gaming, nor a Review. You, good sir, have transcended yourself over the years. Cheers.

[@InsaneWayne355]

Really good stuff here Clint. People tend to forget what a big deal pocket calculators were in the 70's.

[@jacobscarberry4799]

Lazy Game Reviews, I never knew about the calculator wars... very interesting and would love a sequel!!

[@pedrotski]

Just watched all the Tech Tales videos. Cant wait for more!

[@aaronzvz]

Fantastic video. Made me get all nostalgic for the early 80's when I was a kid playing with my Dad's calculators.

[@backfandango]

yes! love your tech tales series! I was hoping you'd mention the TI-85 in there, that's where I jumped ship from the calculator wars myself haha.

[@yokab]

thanks man, would have never known that without this series

[@fozaldo]

Love your channel, thanks for your effort and time. Keep em coming.

[@littlemikey46]

Great video LGR! Very well presented :D

[@Seegalgalguntijak]

@01:06 - I've found such a fascinating all-mechanical calculator when clearing out my grandpa's attic, but it was a Walther, German model, produced from 1948 to 1970. I went online and even found the manual. It's fascinating, how you still had to be able to do maths in order to do calculations with it!!!

I still have my Radio Shack EC-4014 scientific calculator (which is really just a rebranded Casio FX-85m) in pristine condition. Actually the only reason I wanted it was that it could do fractions, which I'd never seen on any other calculator up to that point. The ability to use hex and binary also came in handy for programming on the C64. I haven't really used it in years though. During bulk trash season, I've found 2-3 TI scientific calculators. The ones where the battery wasn't dead still worked fine. I also found an old Commodore calculator (not scientific). It works, but some of the LED segments don't light up and it actually makes a barely audible whine when you press the buttons.

My grandparents had a TI-59, and the PC-100C thermal printer it could dock to... That was a hell of a piece of kit back in the day. With the magnetic card reader and all. I remember the vinyl pocket folio with pages upon pages of those magnetic program strips... Cool stuff.

I’ve got a Friden EC-132 which used to belong to a local college. When it was new in the mid-1960s, it cost about the same as a small house, and looks like something from the bridge of the USS Enterprise. It has a small CRT for the output and inside features eight large circuit boards. It still works perfectly!

i still remember my first calculator. my parents bought me a scientific calculator for $40 in 1975 as a hs graduation present. per dad's copies of popular science magazine, something similar would have cost $100 in 1974, and in 1973 that same $100 would have gotten you just a basic 4-function calculator. nowadays, the scientific calculator i took to college costs less thän $10 at back to school sales, änd a basic 4-function calculator can be found at any dollar store -- if some company doesn't give you one as a freebie.
