As a kid, I got the compact cassette version released by Tiger in the mid 90's. I loved it. My mom hated it. The cassette was labeled 'right' in one side, and 'wrong' in the other'. If you played the 'wrong' side, everything sounded backward. I quickly realized they were using the two stereo tracks from the 'right' side and the other two tracks from the 'wrong' side, but recorded backward. This provided for the 4 audio channels. The mechanism used the playing head from an auto-reverse cassette player to pull that off. When I figured out how it worked, I wanted to make a custom program for it, so a friend of mine and I started planning the questions and different responses. Since we had no means to independently record the 4 tracks of a cassette in different takes we limited it to two options. The fun part is that since we also didn't know how to record the two tracks from the 'wrong' cassette side, we started talking backward, which resulted in lots of fun, with very weird-sounding results 😁. But all in all.. It kind of worked!! Fond memories ❤ ....

[@KevinArcade87]

And what field of work you ended up in?

[@Nukle0n]

Sounds like it used a 4-track head, which isn't quite the same as normal auto-reverse where it flips the playhead. 4-track heads are more reliable but they have the downside that you can't record the whole tape in one go with them.

[@radexx]

[@XanderRowlet]

The Audacity breakdown of all four tracks really helps to demonstrate what’s going on. Thanks Mat

[@LakeNipissing]

The "choose your own adventure / pathway" is what they used the different tracks for, but the most clever thing of all was making the tracks absolutely identical and in sync when they needed to be. This made it very convincing for the user, because it didn't matter what button was left pressed in from the last answer. I never had one, but friends of the family did, I believe they had it around 1979.

[@henrikherranen2610]

And yet, it could easily have been even more complex. Even though the device has a proper stereo head, it is now wasting two tracks for each mono signal. By adding a bit of electronics to let the user choose not only the main track between 1 and 4, but also between the left and right head, there could be 8 instead of 4 different selections and the amount of possible paths would be greatly increased.

[@narkspud691]

@@henrikherranen2610 One of the stated selling points at the time was that it could play regular 8-tracks. And to split it up into 8 programs would've required additional custom-designed electronics, and it was a pretty expensive toy already. Don't dis my 2-XL!

[@mrh829]

As 8-track tapes fell out of style, the inventor of the 2-XL licensed his technology to the owners of Sesame Street, which resulted in the Talk 'n Play cassette player. Each tape also came with a book that would tell stories, and ask the user to answer questions about what was happening in the story. The fundamental principle is the same, in that it used a 4-track mono system, and there were 4 colored buttons to change tracks (likely very similar to the 90's re-release of the 2-XL)

This multitrack idea was also used for PS1 games such as Parappa the Rapper and Unjammy Lammy, etc, to change the mood of the music as the player got better or worse in their responses.

8 tracks-tape has been the bane of my early engineering years. Even when - in the late '70s - early '80s the Philips musicassette was prevailing, there were a bunch of grown-up who refused to give up their 8 tracks-tape players. These players were terrible with their neverending tape mechanism, they kept jamming - especially when people used them in a car during the summer. People were strangely attached to the system. Ah, the AC188-AC188 germanium transistor complementary couple shorted when you looked fancy at them. 1 full RMS watt per audio channel! The mechanism in the 2XL toy you have there is one of the late ones, they became incredibly cheap by using stamped metal parts. Thank you for the trip down the memory lane...

Reminds me of the first days of interactive cable tv when you had a terminal that gave you access to games, amongst other things. It just gave you multiple choices and when you typed a number you had to wait about 1 minute before entering the game and once you were in you had to answer the questions by typing in the right number on the remote control. Everything seemed to work in some sort of a loop and that's why you had to wait for that part of the loop that corresponded to the answer you provided to the terminal.

[@GeoNeilUK]

Bamboozle was more like that, a quiz that was based around the coloured Fastext buttons on the remote that were programmed to go to hexadecimal numbered pages that couldn't be dialld in from the remote (no buttons for A-F) Because there was only one right answer, one button would take you to the "you're right" page and the other three would take you to the "wrong" page. It meant you could cheat by looking in the top corner and seeing which page number the buttons would take you to!

By far the most sophisticated program cartridge on 2-XL was the game *TRI-LEX*. It added a tray on the front that you could put checkers into, similar to Connect-4, but smaller and triangular. The 8-track cartridge was sophisticated enough to play a decent game against you. Eventually, I discovered that it was possible to win Tri-Lex every time so long as I went first. Even when I played it as a 2-person game against someone else, there was a pretty easy strategy that was *provably* unbeatable. I can see why Tri-Lex didn't catch on outside of the 2-XL world.

[@LoveClassicMusic0205]

There were 4 different games. Whoever went first could always win if played correctly. I seem to remember there were 2 where you got to start first and 2 where 2-XL started first. I believe it was possible to win 3 of the 4 games due to the fact that 2-XL made a mistake on one of the games where he played first. The fourth game was played perfectly by 2-XL and the player would always lose that one.

"New York could use a Batman". It was not lying. Crime was ridiculous in the 1970s. Buildings were burned for insurance money, The 1977 blackout, Subway Graffiti, Abandoned buildings, etc. Watch NY77 - Coolest Year In Hell here on KZbin.

[@eriklarson7023]

I still have my 70’s style 2-XL in a box in my garage, along with a few 8-tracks and the button overlays. Wow, hearing that voice brings me back.

[@himynameissam]

I had the 90s 2XL robot when I was a kid! I remember I bought it unboxed with no tapes at a yard sale. Because of this I had no idea what it did, I just thought it was a robot shaped cassette player. Super cool knowing now the real purpose of it!!

[@affablesupernova]

Did you never wonder about the Yes/No/True/False buttons at the bottom?

[@galaxianova8132]

I would definitely like to see the 90s 2XL in action and any repairs if needed. I find these things absolutely fascinating.

[@nomusicrc]

I love how the eyes flash in sync with what he's saying Thank you for going into such great detail about what's on each track What happens if you let it play to the end of the 8-track How does 2 sided cassette tape work

[@bilinasmini3480]

I had that little brown monster as a kid. I was probably around 5 when I got it. I played with it for hours. It remains the only 8 track device anyone in my family ever had.

[@keziski]

The '78 joke at the beginning killed me

[@WatchFlares]

What a wonderful old device. Love the production quality of the cartridges.

[@jason_a_smith_gb]

Liked the way you repaired them.

[@user-td4bn6ju4p]

As a kid, I as absolutely BRUTAL with these kinds of toys. This one in particular, my brother and I would intentionally pick the wrong answers for the LOLS, but you could also flick the buttons in just the right way, to get the head movement mechanism to stop half-way between tracks. Which was hilarious.

[@SE-lc4hm]

I had the 90s Tomy version (the eu/Uk version I think). It is hands down the most vividly remembered toy I remember having - my dad would also wind me up over it and tell me it would grow wheels after a while 😂 I went and reacquired one a while ago from pure nostalgia.

[@orellaminx3530]

I had one of the more futuristic looking ones that used cassettes. My favorite tape, of which I cannot seem to find any information about today but vividly remember, was retelling of The Battle of Fort McHenry, with some multiple choice questions and a few branching paths, if I remember right.

[@davidbwa]

That's a very creative use of the 8 track. I lived through the invention / rise / fall of the 8 track but I'd never seen that.

[@hatpeach1]

Your ability to make crappy toys interesting is pretty remarkable. One of the best channels on KZbin... and I can't explain why! Thanks, Mat. Another one that I totally enjoyed watching.

[@NanoBurger]

I remember 2XL vividly. It said that its purpose was helping its users "to excel." After an hour of going through tapes, we all lost interest and it is probably in some landfill or thrift store. I guess we just couldn't excel enough for that machine.

[@RCAvhstape]

I vaguely remember this from my childhood, though I never had one I saw it on TV commercials. As a kid we could always sniff out the "educational" toys from the real toys and instinctively knew to avoid anything "educational". Never understood how toy companies thought kids were too dumb to figure that out. We got lots of lecturing in school; toys are for playing.

[@DaVince21]

"Test it out with a _normal_ tape," he says, whipping out his disco rendition of Star Wars music. Techmoan, never change.

[@BlytheWorld1972]

loved it

[@HanMasho]

Oh my god. The way the robot says, "thank you for turning me on" has the exact same cadence and delivery as Smithers' PC startup noise where it uses Mr. Burns' voice to say "Smithers, you are quite good at turning me on."

[@Muonium1]

This is EXACTLY what came to mind when I heard it to the point that I wonder if it was the inspiration for the writers of that line in Lisa Vs. Malibu Stacy.

[@HanMasho]

@@Muonium1 I know, right? It's absurd just how similar they are!

[@F40PH-2CAT]

You probably should ignore that.

[@dropgold]

This demonstrated cleverness in the production and design, but also shows how detailed and informative 'Techmoan' has been in demonstrating how it works. I never owned an 8 track device, but you have demystified the usage of this fascinating entertainment :)

[@wbfaulk]

"Techmoan". It's right there in the channel name.

[@aWOLtrooper]

Technomoan sounds like a genre of shoe gaze jungle trance music.

[@dropgold]

@@wbfaulk You will be glad it has been corrected.

[@swk38]

being 9 years old when this came out, it was pretty easy to figure the trick to it, and switch to the correct answer. spent hours listening to the wrong answers, and played the tapes in a regular 8-track player would give ~ 80 minutes of entertainment...

[@drnautas1098]

I’ve still got the one I was given for Christmas (I’ve even got video of my meeting 2XL for the first time under the tree which was recorded on Sanyo V-Cord II tape). And it still works! Was absolutely my most favorite toy throughout all of my childhood.

[@squirrelsguy]

This was my first music player! I never knew anybody else who had one, I lots of carts but usually just played captain and Tenille and Statler brothers. Ahh memories...I still smell the Christmas I got it.....

[@ashleyzinyk4297]

7:00 "The mechanism reminds me of a mechanical telephone exchange" - That was my first thought, too. It's like one element of a "step-by-step" switch.

[@FriendlyNeighborhoodNitpicker]

I love this thing growing up in the 80s and early 90s. I was an audio nutt, being blind, even had my own 8-track recorder at one point. So I understood from an early age exactly how this thing did what it did. But I still really enjoyed it. Of course I also did the things you’re not supposed to do with them: left it on one track for an entire cycle, then move to the next track, and so on, just to make sure I heard all of the responses, but I had countless hours of fun with this little dude. at least until my mother decided I was too old for it and made me throw it out, probably when I was about 12.

[@tristonrussell]

Wow. I missed these devices by only a few years..but I agree... the clever multitrack production is the genius. I suspect that the process would have happened on an 8 track 1/4 inch multitrack master.... recording in pairs (1+5...2+6 etc or even on mono singles). Our host then records the master questions (on all tracks) with gaps for answers....then "punches in" the answers on the required tracks with padding sfx as required. You can even hear him "speeding through" the script to finish in time! Then I suppose it's a case of duplicating the whole 8 track master onto the carts. Very cleverly done to give such a great illusion. Great video!

[@cgbolton1]

I was glad to see that Star Wars 8-track you were testing with. Back in the day my parents gave me that on LP and it was one of my all-time favorites! The LP cover had the same graphic.

[@jamesslick4790]

I had the LP too! Cool Stuff!

[@BlackMageDark]

Same!! As a kid I thought I had imagined it was a thing (bc later on my bro took the LP with him when he moved), so when I encountered it again I was so excited! I now own the one-sided single, such a jam

[@cdmccul]

Was that something like "Hooked on Star Wars"?

[@cdmccul]

I found it in other comments... "Music Inspired By Star Wars And Other Galactic Funk" by Meco.

[@trublgrl]

I am right there with you. My brother had the vinyl single of the Star Wars Theme by Meco and we were disappointed that it was a disco version, not the soundtrack version. We still played it a lot, though.

[@WH32R]

I honestly almost snagged one at my local goodwill a few months ago for next to nothing, but had turned it down due to the power cord. Wish I had know it was so simple to make a cord then.

[@shuruff904]

I have one !!! I swear I've never met anyone else with one, and only ever saw one in an episode of some cop reality show my dad used to watch....I've got 6 "games" with it too....bought it complete with box and manual at a flea market for 4 dollars....I'm looking at it now lol

[@Dreams_Of_Lavender]

The brown robot toy with an 8-track player, playing a Star Wars themed disco cartridge, has got to be the most 1970's thing that I didn't expect to see.

[@KingAlone516]

I never knew 2XL was out in the 70s and used 8--Tracks instead of cassettes, I had the early 90s version and thinking about it brings back so many memories, i should try to track one down for the nostalgia.

[@m.m.radiochannel1969]

Cassettes came later and I think was made by tiger the original factory I went out of business.

[@BrainSlugs83]

2XL was also re-released in the 90s, it looked completely different and used cassette tapes. I had no idea this 70s one existed because I had the 90s one. Crazy!

[@cosmosisrose]

@@electrictroy2010 they may have commented before watching that part.

[@Alchemistmerlin]

I had the grey and blue 2xl that used the tape cassettes instead of 8tracks as a kid, and it is one of my most fondly remembered toys.

[@cardinalhamneggs5253]

Fun fact about the first question on the "Science Fiction 1" tape. _Space: 1999_ and _UFO_ were both live-action sci-fi shows produced by the same group that produced the original _Thunderbirds_ series.

[@daviddavidson2357]

The way it says Kweschion! sounds less robotic and more fresh Prince.

The added Audacity explaination of the tracks is a really good addition to the Patreon version, could not have been done better.

[@jnorth6022]

How ingeniously the audio programming was mixed together! Must have been a fun device, provided a large catalog of tapes. Thank you for this excellent video!!!

[@TimewarpedCo]

You brought back some great childhood memories. 2XL was probably my favorite toy, wearing out the cassettes after multiple listens.

[@stearnshd]

I LOVED this toy as a kid. Turning off the lights once and those red glowing eyes scared the crap out of me! Lol I remember owning an attachment where you could play checkers with 2xl. Thanks for this video!

[@ZipplyZane]

Huh. So there was an older 8-track version. I had the compact cassette version, which looked quite different. It took advantage of the stereo tracks of both sides of a cassette tape to get the four tracks. And it used the same voice. Though the casettes were longer. They didn't use cards for the choices: it just listed multiple options on each button.

[@krzysztofczarnecki8238]

I'm surprised they didn't use an extra switch on the 8-track version to make either the recording twice as long, or the tapes half the physical length since they already have a stereo head.

[@tsm688]

@@krzysztofczarnecki8238 Thing is, doubling the capacity of the tapes would mean twice as much production time. It might have been worth it if they'd had more ambitious content, choose your own adventures etc. Buuuut, choose-your-own-adventure hadn't been invented yet. One year early!

[@davida1hiwaaynet]

Very neat! I always loved playing with toys like this. Learned a lot from the creator's content; and also learned a lot from studying how these worked. Very cool and thanks for sharing with us!

I wanted to say hello from America and also thank you so much for your films these are some of the most entertaining and educational films that are available on KZbin. I love every single film that you do and very thankful that I found your channel.

Anyway, thank you again and much love and respect from America

[@thesteelrodent1796]

"you clearly used the bat computer" - the 1978 equivalent of "you googled the answer". This thing is really clever made. I assume the tapes don't all follow the same structure, so you can't just leave it on B to always have the correct answer - at least I would've made it so you can't do that. There have been some modern games on DVD that used a similar approach, where the answer you pick makes it jump to specific point in a certain video file. Of course DVD scripting is slow and less elegant, but it's the same pattern of jumping between different tracks within limitations of the media. Scene It on DVD (the board game) partially uses this principle although it relies more on self discipline than scripting.

[@tsm688]

it's funny how tech has gotten slower in some ways... Why should a randomly-seeking disc be so much slower than an 8-track, LOL.

[@zimbu_]

The inventor provided the voice as well? Holy moly that's a talented fellow.

[@dRevnik]

also quite high pitched and fast talking fellow!

[@joethompson11]

I was just looking at his Wikipedia, he's a talented man who was still producing hit toys as late as 2004. There was also a TV spinoff of 2-XL he was executive producer of! I'm guessing he's retired now, 75 at this point, what an interesting life he must have led!

[@MrButtonpresser]

I must congratulate him on his "cartoon" voice, very 60's/70's

[@OofusTwillip]

@@dRevnik Not really. The recording was sped up a bit to raise the pitch. This is a very common technique. It was also used on Mel Blanc's voice when he voiced Tweety Bird and Daffy Duck. Daffy's voice was just Sylvester the cat's voice, sped-up.

[@dRevnik]

​@@OofusTwillip Wow, that's incredible! Thank you! You know, maybe you can explain to me another thing I am wondering about for a long time: How does Techmoan fit inside my computer screen? He looks like a fully grown man, yet he's somehow able to squeeze inside the display. And is he in there all the time? What does he eat? Shoud I put him some food inside from time to time or something? Idk, thank you in advance!

[@spontaneousmixx]

I had one of the 8_track 2XL units as a kid, i don't remember what tapes, but here's a thing that happened. My brother and i were arguing over an answer and pushed the buttons several times, before responding 2XL said "i think i have a tummy ache"

[@gerowen]

That emulator is the coolest thing. My wife and daughter are doing the "Are You Afraid of the Dark" tape in the living room right now with all the lights off.

[@wardrich]

Man this is so interesting - the questions appear on different tracks AND the answer was cognizant that you had picked a wrong answer off a wrong answer. The amount of work that went into producing and timing that tape seems incredible to me. Even seeing how it was done, it's still incredibly well thought out

[@piccolo1976]

Always loved the70's disco version of the Star Wars theme, very suitable test cartridge! I was more of the Omnibot generation, but I'm quite impressed with the way this works. The voice reminds me a bit of Dr Frink! Thanks for the emulator link.

[@willsisskind]

2-XL was my jam back in the day. I had the updated version for the '90s and gotta say, they gave him a glow-up!

[@gregx5096]

Another fantastic internals and deep-dive vid. This toy fascinated me through the early 80s - I remember at least once playing through leaving the Q button pressed throughout to hear what was on that specific track. Thanks for the word on the emulator too!

[@Flashy7]

The branching and different questions according to the previous answer is great, it IS more complicated than I thought. The designer (I should say writer) knew that this is a simple toy, but he still wanted to give the most playability (and replayability). It could have been really complicated it they used all 8 tracks and even more if they found a way to switch heads automatically with some control signal on the current track (even if only could just jump "up" to the first).

[@LegionOfWeirdos]

"...you might be a similar age to myself. Seventy-eight." At first I was like "NO WAY HE'S SEVENTY EIGHT!" I was ten when I first saw a 2XL, and when I immediately realized how it worked, it was still pretty easy to suspend belief when playing with one. There was one on display at a department store we'd frequent and my brother and I would play with it all the time.

[@AdrianDX]

This is super cool! Thanks for showing us how it works and for going through the different tracks =) I love how simple yet clever this is!

[@darrenharman3362]

I remember my friend having a 'learning toy' in the late 70's. A bit like this, that used what I can only describe as a mini disc sort of cartridge. really can't remember what it was called. I remember it played a recording of Neil Armstrong's 'One giant leap' speech from the moon landing.

Ah, 2-XL! I had the original 8-track version when I was a child, and loved it immensely. Also liked keeping it in my bed and playing one of my dad's 8-track tapes (though we were never cool enough to have "Back In Black" on 8-track - mad respect to you for that!). Eventually, it stopped working, and an uncle of mine offered to take a look at it... never saw it again after that. (sob) Great episode, Mat! Thanks for the flashback!
