A very odd Walkman. Ever used one of these?

[@danielrfry]

I used one of these, it may very well have been at Penhow Castle (I was in primary school at the time!) They were given out with cassettes containing a spoken word tour (so there was no tour guide present). As I remember, the tape would pause automatically at certain points and pressing the restart button would continue playing, to allow you to wander around at your own pace. I guess there must have been a hidden signal on the tape.

Yes, I remember these. I used to work in a stately home in Wales: Tredegar House, and we would use this exact model when we had days where there were too many visitors for normal tours and they had to self-guided instead. The guy who made them owned Penhow Castle (which is between Newport and Chepstow, it's the studio that is in Cardiff) and IIRC used to be a film director or something similar, and then bought the Castle and wanted to find a way to bring things to life, so made these things. As I remember, the visitor would press play and that would then play a pre-dertermined piece of dialogue, which would then stop and give them instructions on where to go next at which point they would press resume. Don't remember any RF barrier-type installations though. They were, for those of us who had to collect and distribute them, a pain in the a*se! And you couldn't get them to play The Stranglers for love nor money!

Hey Matt, as far as I remember they didn't have any anti-theft in them apart from the writing on the back. The auto-stop was a signal on the tape, normal audio tapes can also trigger it depending on the music, used for self tours (to a pre-set route with a paper-map in some cases!) also had translations into other languages for overseas tourists. Soundalive also did most of their recordings at their own inhouse studio.

I was heavily involved with the digital tour guide handset that was the successor to this particular taped based tour guide and know the owner of Soundalive very well. I never got to examine the taped based one but I am sure that the auto pause feature used a tone recorded on the tape which caused the mech to stop. This is almost certainly why the mech will pause if it is placed close to a wifi modem or a phone as these devices can easily induce signals into the playback head. The tone decoding would have been quite primitive back then so could easily be triggered by strong RF interference.

[@nathangay2563]

I remember something similar to this at The Hermitage (President Andrew Jackson's home in Tennessee) as a kid. It would pause after every display or site on the tour and you had to hit a button at each new site.

[@filanfyretracker]

goes to show how things change too for isolation in such devices. when this was made very few personal level RF emission devices existed, and certainly not in the 2.5ghz or 5ghz ranges like modern dual band wireless routers do. And of course we all carry tiny highly advanced radio transceivers on us every day too, phones which now go across a broad range of frequencies depending on your carrier. I am not an RF engineer or any engineer of any kind so I dunno if my iPhone ever broadcasts across its full capacity or if it gets a config file from Verizon that says "we only use these frequencies" and then the driver for the radio only allows it to use those.

[@sfmc98]

[@deusexaethera]

WiFi broadcasts in the multi-gigahertz range. There is absolutely no way an audio tape could store a tone recorded at such a high frequency, so interference from WiFi couldn't be replicating a signal that was plausibly intended to make the tape player stop. It's much more likely that the player is reacting to 60Hz (or in Europe, 50Hz) RF being generated by a nearby power transformer. 50-60Hz is a very-low-frequency sound (subwoofer-range) that audio tape is capable of storing, but well below the audible frequency range of whatever cheap headphones were used with these walking-tour tape players.

However, in 1994, when the 50th anniversary of D-Day seemed likely to generate a massive influx of visitors, the system was felt to be too labour intensive to be viable.

You could run your frequency sweep tape on it and see if it stops it. The one you tested your spectrum vu-meters with. Use a very slow sweep in case it needs a second or so to detect the signal. I'm guessing it's a higher frequency that cannot be heard when playing back the tape with this device.

Speaking as someone who once worked in the Location Based Entertainment industry, audio tour devices aren't just to enhance the experience of visitors, they (well, some, perhaps not this series, since it seems to be "portable/optional Muzak™ for museums") have a sneaky ulterior purpose; the timing on the tape of the descriptions for each tour area keep guests - notably dawdlers - moving along more smartly - always desirable. ;)

[@Doramius]

Mammoth Caves in Kentucky used these on a VERY short trial during the 90's (can't remember the exact date) in an attempt to be used with a "semi" self-guided tour. The trial may have lasted 2 weeks to a month. It did not work completely the way intended and it was immediately ditched. Any security device would be installed by the place offering the tour, for system compatibility. The units did not come with a security device. I think the cassette itself was what caused the unit to stop. As you were listening to the guide on the tape, it would finish the specific portion and stop, so you could walk to the next part of the tour and press restart at the next station. Some of the problems with the trial were the inability to go back if you wanted to hear the guide information again. They also seemed to not handle the wear and tear very well. Along with a few other issues, they felt that overall it was not a cost effective device to continue to use. I only saw them the one time on a visit, and then never again. Only a few of the older park rangers that did tours in the caves would remember these.

[@tilmanahr]

Yeah, the inability to have it repeat some section of the tour was what stood out to me as a show-stopper. I would have positively hated those things… The one I tried out at some museum here in Germany in the late nineties, early 2000s was a bit more sophisticated, and would allow one to repeat the last bit of the content. That was actually a decent experience. Still not quite as good as simply reading the texts by the exhibits, but probably a good solution for places that don’t want to or can’t place a good bit of written material next to the exhibits…

I'm pretty sure (it was a long time ago!) that I used one of these at Penhow Castle. One my friends dropped his and the cassette fell out. When he put it back in, it automatically rewound back to the beginning and there was nothing he could do to stop it. His group had to stand and wait while he listened to the tape and it got back to where they were. So while they didn't have a rewind button, some of the models may have had an auto-rewind feature to make sure the tape was always at the beginning for the start of the tour.

Westminster Abbey had a similar system around the late 1990s when I did the tour, but it was spoken word rather than just music playing and they did give you fair warning it'd set off an alarm if you tried to leave without it.

I believe we had to press the restart button every time we were in a new location in the tour. I think there might have been a tone on the tour tape that would make it stop when the audio was finished that would have stopped the tape (like a broadcast cart tape). Good find!

[@BrightBlueJim]

A tone on the tape makes more sense than those who have suggested that they got triggered to pause by an RF signal when you got to a certain location on the tour route. If it was triggered by RF, then if you waited too long at one location in the exhibit, you would start hearing the narration for the following location. It's not clear from the video, whether Techmoan verified that playing a standard stereo cassette actually played it back in stereo. My guess is they just recorded the narration on one track, and fed that to both sides of the headphones, while the second track was used only for cueing.

[@r1w3d]

When I was a kid these were definitely used at the museum I would visit on field trips. M.O.S.H. Jacksonville FL is the museum. These were seemingly phased out by a narrow motion sensor that covered approximately a 2 ft circle with a downward facing directional speaker system. If you walked up to dinosaur bones, corral tanks, native American relics, etc... it would start up and feed you info which surrounded you facing any direction as long as you were in the correct position. Half of the Walkman had cracks or chips in them. I'm sure it just wasn't a cost effective way to inform people. *edit* I'm now curious if I can pull strings and possibly get my hands on one if any still exist hidden away at the museum. As a broadcast engineer for TV and Radio I get a few perks or benefits. I'll find out if I can aquire one through a few people.

Yup, sounds like the FM receiver is used for this function. The wifi just swamped everything with pulses that got into the stop circuit. It should be possible to find an FM frequency that triggers it. Maybe use an FM radio to find he local oscillator then subtract 10.7mhz and tune a transmitter to the result. Modulate the transmitter with an audio tone and find the audio frequency that makes it stop. Nice work Matt and commenters

[@wbfaulk]

I wonder if, when the tape playback stops, it switches over to radio receiver mode. Maybe tour locations could have short-range transmitters that would broadcast something about specific locations that would break into the tape playback when you got close enough.

[@hartoz]

The restart was for resuming playback after visiting a waypoint in the tour. I think you will find if you open it up, that there is a little radio receiver inside that when triggered pauses the playback after a section has played, the user would then hit the button at the next waypoint.

I used one of these in 1987 on a walking tour of the Hermitage Andrew Jackson's home in Nashville, TN.

[@alaricsmith5558]

All I can remember about Soundalive was that they did tapes about different periods of music in history. I remember that did tapes of Tudor music (mostly Byrd, Bull and Tallis - that well known beat combo ...). I think that the tapes came with a magazine, a bit like the Blues mags and those ones that let you almost build a replica warship, race car or part of a Millennium Falcon. I don't think that they weren't anything to do with exhibits/museums. Perhaps this was in a shop with the tapes and magazines?

[@alexmorrice7247]

Past Times used to sell them - it was a high street shop that specialised in museum-style gifts. The Tudor cassette was rather good, as I remember. I'd certainly buy it on CD if it was ever rereleased.

[@MrCanoeheadful]

So, one company but two unrelated cassette-based products.

[@henrickbull]

We had a slightly more advanced Walkman model of SoundAlive here in the states. It was an MP3 player the first time I saw it and it was being used at the natural history museum at the nearest city. I remember we used them when we had a school trip and they didn't have enough tour guides to deal with all the children. So they preloaded some thing about ancient Egypt which was the current exhibit and the museum and set us loose to follow the SoundAlive tour guide. A woman named Kristy was the voice that guided us through the past of ancient Egypt. I recalled it played music, and when you arrived in particular places the tour guide would speak up and would tell you which direction to look and everything. I recall there was a bunch of jump cuts in the audio so I think it was some kind of modular system, the museum would go "Ok the sarcophagus is on the left on the tour so that's what Kristy needs to say." The tech fascinated me as a kid.

[@TheLambLive]

Yeh, I did the same tour as Dan Fry at Penhow Castle back in the 90's. Can confirm. As far as I remember, there was a sign saying to press the yellow button and you would get a spoken explanation of the area of the castle you were in with a bit of 'ambience'.. then it would stop, presumably by a signal on the tape, and you would move to another area and there would be another sign to restart, playing the next bit of the tour. Perhaps the 'remote' shut off capability was deployed at the end of the tour in there area where the tape decks were returned to ensure they shut off to save battery and tape life, but I'm not sure on that. Maybe the cut-off is using an ultrasonic tone, and something within your room is generating or inducting a tone at or above the ultrasonic trigger frequency... Pure speculation on my part though.

[@danielrfry]

I was wondering if it's actually a low frequency tone - can be recorded reliably on a cheap tape, won't be audible on basic headphones, won't be noticeable when the tape slows down when it pauses. Mains hum has a base frequency of 50Hz I think, that's probably out of the response range of cheap headphones, and likely to be picked up by unshielded electronics in the Walkman when demoing it in a studio full of other equipment!

[@marsilies]

The description's been updated to note that the music-only tape was probably sold in gift shops at the end of the tour. I'm guessing it's the same music used for ambience behind the narration, so the music-only tape's sale proposition was like "Did you like the music playing behind the narration? Well, you can take that music home with you."

[@greendryerlint]

I'm thinking it's RF, and the router or smartphone is causing it due to some frequency harmonic that manages to trigger whatever cheap receiver is in it. It probably just responds to a single frequency, not any coded signal, like garage door openers in the 1970s that would open if CB radios were keyed near them, aircraft were overhead, or probably if someone shouted loud enough. lol.

[@TassieLorenzo]

@@marsilies Excellent! I find it curious that Mat doesn't like Tudor folk music, lol.

[@snerls]

While i'm not 100% certain that it was this exact model, i did a tour of Caerphilly Castle some 20+ odd years ago, and i remember using this (or at least a very similar) device as a "tour guide". Put the headphones on, hit start, and you were given a short explanation of how it works, pointing you towards the first point of interest (these were marked with plaques). The tape stops at this point, and the idea is that you hit Play again once you're at the POI. Rinse and repeat, i think the total process came out to a good hour. This was actually really nifty as a child!

[@nickshipway8199]

I remember using one of those at (I think) the Natural History Museum in London back in the 80's. I walked around the terracotta warriors listening to tour info. You leave the play button down and the tape automatically pauses at the end of a section. You'd press the yellow button to start the next section. There wasn't a your guide controlling anything, it just stopped at the end of each recorded section. I always thought there must have been a special signal on the tape.

[@JeanLoupRSmith]

I'm impressed so many people remember what kind of device they used on a tour of a castle over 30 years ago

[@redavatar]

I immediately recognized these or something very similar from when I was a young teenager being taken to museums on school trips. The thing is that these tapes would have certain marked spots where the player would stop playing similar to what you saw in the video so without some signal being sent out. If you moved to the next exhibit, pressing "restart" would continue. This way you wouldn't accidentally be skipping a load of exhibits by wandering too long around one exhibit. It's well possible they worked with a combination of on-tape marked spots & signals that would stop the playback when something at an exhibit would happen.

[@mydrive538]

Thank you for being our “time machine” that brings us to the 80’s and 90’s

[@gilles111]

Back in the '90s I volunteered at a local museum and we used those machines in the museum for temporarily exhibitions. I also did the voice-over for some exhibitions (I also volunteered at a local radio station so I could produce the master tape pretty easy and cheap for the museum). The WM-TOUR at the bottom stands for Walkman-Tour, those were mass produced by Sony for use in tours/museums/exhibitions/etc. You could lent or rent such a walkman at the counter and at several places during the tour you could listen to a text or music piece (or what the museum suited for that spot). That's why the walkman has such colors, the museum branded it to their own colors to prevent those items from being stolen. And the start and stop in obvious colors so everybody could easily use those machines. The yellow restart is just a pauze button (at the end of the section you would press the pause, walk to the next section and press the pause again to continue the explanation - most tapes had a tone recorded to alert the user to press pause). The use with the stopping via a radio signal was not the original setup of those machines but might be an option - also integrated with the later stop functioning in the alarm system. To prevent users to steal the item or accidentally/intentionally overwrite the tape, the other buttons are removed. Most museums also locked the opening mechanism so nobody could remove the intended tape. Most of these WM-TOUR players were auto rewind, so if the tape reached the end it would rewind to the start position (there were also players which had double sided tapes (A+B side and auto reverse). So at the end of the tour the player just had to autoreverse for the next user. The alarm (if there was one) was placed in the mechanism and had a small antenna which was positioned in the enlargement at the back of the walkman. It worked the same way as the old anti-theft-tags which were on clothes back in the days. Passing a secured gate would trigger an alarm to set off to alert the staff someone forgot to return the device. I know there were models which also might stop playing when crossing a gate, but that technique was introduced somewhere end '80s/ early '90s. A lot of museums (in Europe as far as my knowledge goes) did use them pretty long time up till the early 2000s (when museums mostly switched to digital replacements). Most museums preferred to use this machine above a cd-walkman because tapes were cheaper to produce and didn't have the buffering problems those mobile cd-players had.

[@nkt1]

What if the machine was returned before the tape reached the end?

[@gilles111]

@@nkt1 At the counter the people could open it. At the museum I worked we always checked the tape before handing out to the next visitor. If needed we would take out the tape and rewind it at a separate tape deck. At that deck we could also listen to the tape if a visitor had remarks about the tape (i.e. the tape went bad). We also always plugged in a dc-adapter to recharge the chargeable accu in the walkman. So yes, it was a lot of work to have those machines, the upgrade to minidisk-players (and later mp3-players) was very welcome by the staff.

I used one of these back in 1989 at Penrhyn Castle in North Wales. I think the cassette had a code recorded onto the tape so that when a section had finished informing the user about a particular room, it would go into pause mode until you were ready to move on to the next room. Once at the next room, the reset button could be pressed to resume the tape for information about that room and so on.

[@kevinh96]

I'm pretty sure it was one of these, or a device very similar, that I was given during a visit to Alcatraz back in the late 1990s. It was used to provide information about the place and it's famous inmates as you walked around if you weren't part of an organised tour. I can remember thinking that the headphones looked like those ultra cheap ones you got free with budget Walkmans back in the 80s, all thin plastic with awful foam earpieces.

I grew up in the bay area, and not only took a school trip (I think the state gave us kids free admission to promote state history), but every visiting family member wanted to go to SF and Alcatraz!

[@AstonsVintageTechnologyWorkshp]

I used to be Sony's audio engineer down in Devon, back in the 80s and 90s, if I remember correctly, these units have a frequency monitoring section on the circuitboard that cuts power to the motor, which would have been played from the tape, you just happen to be triggering it by putting it near your router and being picked up by the head. I can't remember whether the frequency for this was below 50 Hz or above 17 kHz, after all, it's quite a few years ago now :-) but a simple test recording would probably prove this. If you can, try a sweep frequency recording, that should give you a good idea of what frequency puts it into pause mode. All the very best from Aston.

I don't think I've never seen one of these before, but I do recall a similar purpose device. More than 40 years ago I visited Calrsbad Caverns in New Mexico. They had self-guided walking tours from the surface down through most of the open areas of the Caverns. Each visitor got a device that was probably about the size and weight of a walkman (although this was, I think, a bit before the Walkman had come out) that played when you held it up and stopped when you let it hand by the neck strap. (I don't know if it was the orientation or the pull on the strap that started and stopped it.) The paths for this self-guided tour were all paved, and the places where there was narration on the device had writing on the pavement to tell you where they started and ended.

the 2.4GHz band that Wifi uses is (and has been for a long time) classified as "licence exempt" which means that provided you stay within certain power and other interference constraints you can use it for anything. Chances are that becuase back before WiFi was a thing and these bands were not used for much outside remote control planes and cars (so would be fairly quiet), Sony did the simplest thing they could for the remote pause and triggered it on any reasonable strength signal without worrying about content. In more recent times the 2.4GHz band is so busy you are lucky that it ever starts at all!

[@minigolfkid]

yeah. not surprised. we’ve had a form of WiFi for decades longer than people realize.

[@gonzo_the_great1675]

In the UK, the 2.4GHz allocation existed for 'industrial, scientific, medical', but was hardly used. Microwave ovens were tuned for that part of the spectrum, because it was available, would reasonably efficiently heat water and I suspect, was convenient for mass produced magnitrons. Data and wifi there is a pretty modern occurance. And certainly not going to be used by a walkman of this vintage. It's more probable that this device is being affected by pickup from mains wiring, or stray magnetic fiends from switch mode power supplies.

I first started working in recording studios in the mid-80s, at the end of the filmstrip/slideshow era. 50Hz "DuKane" pulses were sometimes mixed with the narration and used to trigger the next slide. Maybe similarly "inaudible" pulses were used in the Walkman to pause the unit, and your machine was picking up hum from a nearby electrical wire?

I remember one exactly like this but coloured blue instead of green when our Primary School visited York Castle in around 2004/5. It would (as you mentioned) play music when we were walking around the castle (and then the museum) I remember all the music sounded very MIDI style instrumentals versions of The Grand Old Duke of York and other such tunes. When we got to certain points in the tour the tape would stop and then we'd press a button on the side to get them working again. Nice to see one again. I think my friends had the bright idea of taking one too but our History teacher found out and wasn't best pleased. They had a similar thing too in York Minster, but it was a portable CD Player instead. Guess they had a bit of extra cash to spend!

[@TimmyJoe633]

I remember they had a similar sort of device at a castle in devon i once visited, only instead of a casette player it was just some sort of digital device you carried around with your headphones in . I'd imagine the cassette you got was probably supplied as part of the whole sound alive system to perhaps just play as background music on speakers around the place, more than on the walkman device itself, bit like at warwick castle, they have that sort of music piped out everywhere in the background.

[@3rdalbum]

This seems like a better system than the phablet I was given in Nara, Japan as the audio guide for a bus tour. It was supposed to activate certain clips by GPS coordinates, but it rarely did. You could also choose an audio clip to play manually, but after a while it would ignore your inputs and just keep playing looping background music and forcing a complete reboot. In the end, our tour guide (who was only hired to do the tour in Japanese) took pity on us and translated the important bits into English. We were the only two foreigners on the tour, surprisingly. But yeah, an automatically-stopping cassette system like this would have worked better.

[@Loganlion42]

I think some of these devices where used in US museums i remember seeing similar devices not sure of brand but when ever you walked to certain locations it would stop playing and then restart at others always near a arch which in some case you could tell looked like a metal antenna but those I remember you couldn't remove the tape and it was a continuous loop as could be found out by spaming the restart button when bored in line

I also guess that is why it says “ this payer is not for domestic use” on the back.

Thnx for the lovely video again - as always enjoyed it!

[@josangoj78]

Since the player lacks any rewind or forward features, the original tour tapes should have the same contents recorded on both sides, then the trouble of keeping players ready for the oncoming guest batches was reduced to simple tape flips (unless there were also auto reverse versions with all related controls hidden) Just remembered a Phineas & Ferb episode, where Dad was listening in bed to the final section of a tour tape nearly in loop...

[@tomwilson2112]

@7:46 That's not what is happening here. If you listen closely, there's a low frequency pulsing when the tape stops. What is happening there is the Walkman is picking up some stray EMI near the back of the desk, and it's going to through the play head as low frequency audio. That goes through a low-pass filter that triggers the pause function on the tape. This was used for self-guided tours. The tape would have "chapters" that gave information about a specific spot on the tour. The end of the chapter had the sub-audible tone, which would stop the tape after listening to that section. Radio stations in the 70s and 80s used similar systems to automate their music playback: they had large NAB tape reels that would have a bunch of canned tracks, with a sub-audible tone after every second track. The tone triggered a sequencer that would stop the tape and play some commercials from another tape, play a station break from a cart, then switch back to the music. You can test this yourself by recording different frequency tones onto a tape and seeing if one of them triggers the pause function.

[@ZGryphon]

Oh, neat. I've seen more modern solid-state "audio self-guided tour" devices (and nowadays, rather than deal with the overhead of lending out and collecting devices, a lot of museums are moving to just foisting a junky phone app on visitors), but I had no idea the concept went as far back as the cassette era. I wonder how institutions that used these things handled earphone* sanitation? Then again, it was the '80s, so it's entirely plausible they just... didn't. * All the people tripping over themselves in a rush to correct me on this point are barking up the wrong tree. I know the Walkman phones of the day were not earbuds. Where I come from, though, those little on-the-ear things are earphones, and "headphones" is reserved for the big, heavy over-the-ear models like DJs, studio techs, and helicopter pilots use.

This makes a lot of sense to have actually if you want people touring to experience music or some ambiance because if you are in a historical site they oft do not want to change ANYTHING to the structure so installing a speaker system would be a no go and setting up stand speakers in areas could be unsightly and not cover the area well. At work we did electrical work for a historical site and you could not so much as screw anything in and had to run sticky back channels to run wires.

As it is a standard Sony mechanism, that would still be there, just missing the button, as it would cost more to design it out, instead of simply leaving out one plastic piece on assembly.

As for the restart (before it was discovered), I was thinking that if you had finished an exhibit but wanted to re-listen to the description, it would rewind the tape until it found a cue tone and you could listen again

I was actually thrilled when you through serendipity discovered the use of the restart button. And when you mentioned the copper plate, I thought "antenna" you figured it was an antenna well it's nice to see logic working it practice.

They still use devices similar to this (but digital) today. Back in 2008, I was visiting Memphis, Tennessee, and visited Elvis Presley's home of Graceland. You can take a tour of Graceland, and when you do, you're given a device that has a keypad on it, and the tour guides tell you to enter a selection relevant to that part of the tour, which plays information about that specific part.

Yeah, they do this so that they don't have to spend weeks training the tour guides. By automating that part, the tour guide can focus on the job of keeping grabby tourists from touching things they shouldn't.

@@shadowtheimpure It worked well from what I remember. Very good audio quality. I don't think it's so much about keeping people from touching things, but to make sure that every visitor is getting the same information on the tour. The only instructions we were given on the tour of Graceland was on the shuttle bus from the visitor's center to the actual tour, the bus driver told us to enter a selection onto the keypad on the device. After each recording was played on the device, it would tell us which selection to enter next.

@@jeepguy95 I was more speaking of their uses in general than Graceland specifically. There are several historical sites in my general area that use similar items to give out the information on walking tours. After implementing them, there was a marked decrease in the amount of 'tourist induced damage' to the exhibits since the guide was able to focus their attention on the guests instead of remembering facts.
