The voicing is gold. Seriously, I can't believe it was the inventor who voiced the cassettes.

[@radexx]

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 ❤ ....

[@winterwatson6811]

Awesome!

[@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]

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.

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]

Oh God, the nostalgia. I had one of these, with three cartridges: General Knowledge (which seemed to be missing from yours despite being the pack-in title), Science Fiction and an astronomy one about the Solar System. It blew my mind when my dad told me it was just an 8-track tape player. I wound up picking up a Best of Chicago 8-track that I found on the side of the road that I played on it. The only music 8-track I played on it, mainly because it was the only one I owned (at the time, 8-tracks were being phased out in favor of cassettes).

@@PauIieWalnuts I remember really liking "25 or 6 to 4," I don't think my 9-10 year old ears had heard anything quite like it. I had probably heard some of the hits on the radio, but at the time I mainly associated them with the yucky ballad "If You Leave Me Now," which was a hit a few years before. Fortunately, the tape pre-dated that so it wasn't included.

[@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)

[@skittstuff]

Aww, this little toy is adorable. It's before my time, but I think if I was around when it came out I would probably be obsessed.

2-XL's voice and pronunciation sound odd, but oddly charming at the same time. I have to wonder how long it took just to write, edit and fine tune the recordings to get the intended result.

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!

Having a reliable mechanism to switch from the left channel output to the right channel output at the appropriate time, and automatically return back to the correct starting channel at the beginning of playback. None of these things would be excessively difficult to make reliably in an 8 track player (as commercial long play systems demonstrate), but making them cheap, robust and reliable enough for a child's toy is a different matter. There may be a system that could have been robust enough to be used that is impractical because of cost, particularly if there are royalties due on a patent at the time. There may have be a cheap enough method that wouldn't put up with the abuse a child's toy receives. And for what benefit? You double the capacity of the toy's tapes... Does that being in extra custom? No, because it is a toy for young children. 20 minute tapes were plenty. There would be no benefit to the added complexity and cost. If this were not a child's toy, it may have been worth it. But children's toy production has two basic rules... Be cheap and be quick to manufacture.

Thanks for sharing and exploring 2-XL. Like said below, showing us how the tracks work was fascinating. I'm 53 and had one when I was a kid... I purchased one on eBay around 10 years ago and he sits proudly on my shelf. For those who didn't know what it was, I always explained it as the robot with the Long Island accent. (Also as mentioned below I too had the Meco Star Wars album you played the 8-track of. Great memories!) Thanks again!

[@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.

[@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

[@hattree]

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.

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.

[@VideoEnjoyer-m3z]

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.

[@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.

[@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!

[@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.

[@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!

[@rogermwilcox]

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.

[@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).

[@larryaugsburger8452]

My sister had one with an adapter on the front that allowed it to play something like connect 4 or maybe tic-tac-toe. The pieces were dropped in slots that would cause button presses. Very impressive for a tape player!

[@tsm688]

Huh, I suppose it could! Just chart out all possible decisions and play replies. Some games would need a lot more buttons than others!

[@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]

[@Charlesb88]

The 90's version of the 2-XL (From Tiger Electronics) that used compact cassettes used the fact that the two tracks/sides on a cassette can include left and right stereo channels so they simply recorded the fours tracks of audio that the 8-Track version used on the Side 1, Left Channel, then Side 1, Right Channel, then side 2, left channel, and side 2, right channel. They avoided the need for an autoreverse head on this device by recording all four tracks of audio going in the same direction and just using a special four channel playback head. Pressing one of the three answer buttons simply switched which channel plays out of the mono speaker and you press the Question button to return to the Question Channel. Of course if you play "Side 2" of these 2-XL tapes on a regular cassette deck, it would play all the channel at once and backwards. I assume the same would be true playing the wrong side in the 2-XL device but with one one channel playing at time. Thus this version cannot play regular audio cassettes unlike the 8-Track version which can play 8-track music cartridges nor will the tape properly play in a standard cassette deck. To archive one of these special tapes, you need to record the left and right channels of side one then the L/R of side 2, then reverse the L/R of side 2. The Lost Media Wiki has some good info on the Tiger Electronics Compact Cassette Version of the 2-XL for anyone interested.

[@markusisaksson6023]
