I’ve had numerous fuses in car cellphone chargers blow on me before, usually when I’m revving. Either the ampere of the power supplied is too high that it the fuse overheated and snapped, or the power supply in the ship spiked for whatever reason and blew the fuse.

Yes, All you can do in the interview is start the tapes rolling, then 'stop' if you need a break in the interview, normally if solicitor or suspect asks for one. At that point you stop the tapes and flip them open to show they're not being recorded as you leave the room.
I knew that VHS tape re-winders were as thing because of video rental, but not audio tapes. But then I thought of libraries. Lastly, I wonder how many of those DVD re-winders that you could find in mail-order catalogs actually were sold. Most of them you could later find populating bargain bins at low cost stores.
This is a true story: Back in the mid-90s, a friend was over and he'd never seen a LaserDisc player before so we watched a movie on it. I gave him the remote so he could control the experience, and had him flip the disc when it was time. When it reached the end he said he'd enjoyed all of it, so I asked him to rewind the LaserDisc which he went about trying to figure out how with the remote & eventually by looking at the front of the machine. Mind you this guy is a programmer - big brains and whatnot. All he could get it to do was play backwards. He was confused. After a solid minute+ of futzing with the remote, the light finally when on over his head and he realized he'd been duped to great amusement on my part. I laughed so very, very hard. [he was an annoying know-it-all to everyone so, yeah, I LMAO at him which no one ever really had the chance to do] It's the small things in life...
@MoseyingFan loads of people had VHS rewinders in thier home because they were sold as being better for your tapes than the rewinder in your VCR. They were supposed to rewind as smoothly as your VCR plays or something like that to prevent wear on the tape.
Exactly this. That's also the reason why it was heavily built with no plastic - because complete reliability was far more important than weight, looks or even price.
@@ZGryphonThat's good, it's a feature of government contracts and shouldn't be treated as a bug. It's been shown time and time again in studies that government subsidised items since the mid 70s obsession with cost cutting have actually cost everyone more in ineffeciencies, breakages, accidents, and even death in some cases. Governments commission quality products, everyone wins. They can do their jobs and we benefit from the government funded parts we can benefit from. They accept the lowest bid for every contract because of "government excess" and the challenger disaster happens.

@@Name_cannot_be_blank I rather enjoyed someone sharing their joy at a particular phrase or sentence. And, somehow I missed the part after the comma, so this post caused me to go back and rewatch that section of the video.
Police use or at least used for long tapes because the recorded tape is a clear physical piece of evidence and police have procedures to handle and store physical evidence. A recorded file on a server requires completely different procedures. While they can be developed it takes time and one cannot just ad-hoc create them. That time recording on the other track was a pretty clever thing.
It also removes the chances of someone managing to electronically penetrate security, find the files, and delete or replace them. One could argue that if a police agency's data infrastructure is compromised, *_anyone_* could make such a change, but if it's stored offline on physical media, then there are far fewer people that are in a position to gain access to it to change, remove, or replace it.
*giggles* One could also argue that an offline server couldn't be breached, as proposed. _"Whats that you say? A computer that isn't connected to the internet/a network?"_
A friend of mine who is a trained typist once worked for the Police transcribing interview tapes made using machines like this. She had to quickly learn the spelling of an awful lot of swear words.
Agree. Recording on a cassette tape is cheap and as physical medium it is easy to archive it without any information loss even for two or three decades. Digital medium is here not your friend. Big companies are still using magnetic tape to record their business meetings and conferences and also a lot data is stored on a computer cartridges with a magnetic tape inside.
It 1:30am and I was like "i'm wasting my time watching this". However I actually found it really interesting and want one of those now! Dammit Techmoan!!
had no connection to lucas, so the led's didnt fail. as to the amount of ic's, the tech is overkill, are they doing something else other than syscon, are they adding some data to the tapes??
When using a bench supply you should set a lower current. Yes, it will only draw as much as it uses but if there is a short then limiting the amount of current it can draw is the difference between a repair and a fire.
Right. Setting the current just a bit above its normal operating current is a good idea. That is what I do. I used to repair cassette player/recorders (among other things) a long time ago.
Oh the memories! Our family firm in Hyde, Cheshire had a contract with Greater Manchester Police to repar these machines. They were built pretty well and were simple to service, and IIRC they came in single and double-deck versions. I think NEAL had connections to Wearite, who made domestic and semi-pro transports.
They likely only used one side of the tape, and made tapes with labels on one side, because flipping tapes runs the risk of flipping the same tape more than once and accidentally recording over side A.
I think it was a regular stereo-type head. When Techmoan digitized the playback audio, one channel was the audio, the other was the timestamps. So it apparently WAS possible to use the reverse side. I could see a procedure when flipping the tape in which it would be standard practice to break out the write-protect tab on the cassette to prevent such accidents.
Nope, you didn't flip tapes or break the tab: instead you'd put the cassette back in its case and then wrap a large, signed label right around the case to seal it for evidential purposes.
I used to work for Mastercare (aka Disastercare), Curry's in-house repair service. We used to fix white goods (fridges, freezers, washers etc) and brown goods (so-called because TVs and entertainment equipment used to have that woodgrain finish).
I was interviewed in 2017 three times in two different police stations and they were recorded on two CD-R's, and the recorder looked a lot like the digital NEAL one shown with two microphones. I remember during the interview I was more interested in the technology rather than the subject at hand! Standard CD-R's were used, I forgot which brand they were.
In the force I work for, we have custom printed CDRs, so case/custody numbers, exhibit references and interview start and finish times etc can be written onto the disc with a sharpie. Don't know who makes the media.
And if they did, I guess him starting to fix their audio would catch them off guard and confuse them long enough so he could make a run once everything's working.
Policeman: We hear you have been collecting classic electronics! Techmoan: Well, uh... I think my refrigerator's running, and I have to catch it! **clicks button on device and teleports home** Policeman: Oh, poo! I just wanted his autograph!
Surely this was an horrifically wasted opportunity to record a puppet interrogation? Hipster puppet and old geezer puppet using the good guy / bad guy routine on Techmoan?
To be fair, if you're in the middle of taking evidence in an interview you really can't have the batteries running flat... Mind - slightly surprised it needs 12V to run.
Wow! 12 V and 18 Ah is 216 Wh! That's enough to power my iMac Retina 4K at full load for two hours! I might buy some alkaline D cells as a backup... Just kidding, I'll just buy some LiPos.
At first I was wondering why there were so many ICs in there, but now it is clear: it has so many failsafe functions plus the time stamp and speech synthesizer system!
Amazingly up till about three years ago these were still in use in the metropolitan police. The one you have is a portable for taking out the police station. It was a laugh explaining to younger trainee coppers what a tape was, often got the reply "Oh my mom told me about these, never seen one in real life"
Very cool old piece of equipment. I too love all the older analog stuff like reel to reels, turntables, etc. Thank you for taking the time to share. Keep the videos coming! 👍
"HMS" Ocean" was the first ship to use "Verbal Camouflage" When they wanted to hide important assets, they could just tell people the person or item was "On the Ocean", and the British military would know where that was, but no one else had a clue. -This was another edition of "The Comic Military Speculation Text-Only Podcast."
Speaking of verbal camouflage... In my hometown, there were bars called "The Office" and "The Garage". "Sorry, dear, but I'm needed at the office tonight. Tom wanted me to stop by the garage after. Should be home around nine."
Those flywheels are HUGE and must give excellent pitch stability. Makes me wonder if, with good heads etc, this might make the basis for a Nakamichi Dragon slayer. ;-)
wraithcadmus - I’d like to see it put through its paces. Tested for wow and flutter, frequency response, etc. but remember, this is a record only machine, no playback, and it is designed to record only on blank tapes. It’s no good at all as a hi fi component.
I first saw this type of recorder shown in an episode of „Midsomer Murders“ where it was used to interrogate a suspect in the Causton Constabulary (I‘m German I might add). You could see it was an interview recorder but they didn’t explain anything further, so thanks for providing this deep insight into this fascinating machine.
SPEECH SYNTHESIS ON THIS RECORDER??!!! YESSSS!!!! I love that! I love the sound of that synthesis; it sounds like it's based from an actual speaker originally. It sounds like they used linear predictive coding! That is a really neat recorder, and built beautifully. The construction is truly a piece of art. Those flywheels are gorgeous!
The TI chip has 9011012 inscription. that stands for either 11th week of 1990 or November 1990. The Philips chip at 8:01 has very clear 9028 date code. Another chip under the front plate has 8912 date code. So that in total makes the machine assembled in the second half of 1990 or, maybe, early 1991 (although I incline to think that it was made about exactly 28 years ago, in September or October 1990). And, well, copyright marks don't mean the year of manufacturing ever, period.
The compartment with the three chips is interesting. The TM70C02NL is a 8bit microcontroller, the 74HTC573 is a latch which can be used as outputport of a microcontroller, and the "LJV1.8" looks like an Eprom. To the right of the TMS is a crystal oszillator. This is a small computer. Oh. Some posted that already.
The next time you want to drill out a screw, please use a left hand drill bit instead of a normal right hand drill bit. A left hand drill bit works counter clockwise, so if the screws catches in the drill bit, out it comes.
You’re right, but why buy a set of them for what could well be a one time only job? It’s not like it was a machine screw that was going to be a pain to extract, just a self tapper that needed to lose its head and meet some pliers. I think he did well enough with what he had to hand.
See @4:55 when he says, "As always happens, you get to the last screw, it doesn't want to come out, and it strips." This indicates that he has disassembled stuff before. And, at @5:40, we see that the screw is right on the circuit board. So, if the screw had gone in, it could have destroyed the circuit board. If you look at Amazon, a left hand drill set goes for $10 USD (ref: amzn.to/2CW0lj1 ) for a cheap set. @Techmoan seems to do plenty of equipment refurbishments.
Mark Holtz - Well, it’s certainly the proper way to do it, no argument there! He maybe could have got hold of the head with pliers and turned it out, or slotted it with a Dremel cutoff wheel and used a flat blade screwdriver to get it out, etc. That would risk damaging the case, though. Sometimes the Ghetto way is more interesting, if not ‘correct’. :-)
+Gernot Schrader Well, yes it "worked" if you consider digging a divot into the aluminum case a proper solution...these days, a set of left-hand twist drill bits is quite inexpensive -- even using a Dremel tool to cut a slot is a better option than what did...and why is he at first unsure of date of manufacture, then later he mentions in passing the late 80's codes on the microchip packages?
Interesting with the time-stamp on the other audio tracks. Official Air Traffic Control audio recordings have this as well, it's not a voice synthesizer, it sounds like a bunch of loud static - it's an encoded machine-readable timestamp that takes up the second audio track.
I have listened to many hundreds of interview tapes on transcript machines over the years and I always assumed that the time stamp was added by the transcript machine, not recorded on the tape. Of course it makes more sense now that I know! The transcript machines also have a speed up/Slow down feature and you can adjust the balance to fade out the time stamp. It would be great to see you get hold of a transcript machine, the ones that we used were slightly different to the one you showed on the video. Great Video. Thank you.
The Texas Instruments chip is a microcontroller from the 80s. I wouldn't be surprised if the speech synthesis in the unit is handled by some TI chip as well. They were leading the market in speech synthesis back then.
12:57 - Yeah that loud, long beep sound when commencing recording is shown on basically every British police interview tape recorder usage on fictional dramas and real-life documentaries alike. As well as being used to get past the lead-in, it was also probably useful for functional reasons because it gave a totally unambiguous and unmissable signal to officers, suspects and lawyers that recording had commenced. It also worked as an interruption and reminder for the officers, suspect and lawyers to stop talking while the noise was happening, so there was less risk of the actual recording commencing with someone mid-sentence and there being any future ambiguity in court about what was being said or intended.
The inside of that deck has some very high quality components-that large blue capacitor for one and the toroidal transformer.All the wiring is very neatly cable tied which is very similar to the inside of my naim audio gear
I have had a few interviews on these. The voice is called a “chinaman” I was told by a policeman! They are supposed to beep for a few seconds after switching on.
Reliability will always win against power consumption. And solenoids like these are way more reliable that mechanical parts that usually break pretty easily. And that thing actually runs plugged in, not on batteries.
This looks very much like “mil-spec” hardware. Remember that these kinds of things were purpose build for military use. Although I don’t know for sure about The Royal Navy, as a former USN technician I worked on all sorts of electronics like this. It’s build to withstand poor power quality, rough seas, must be able to be trouble-shot and fixed at sea (in rough seas too), handle salty and humid environments, and whatever else war and sea-duty can do to it. Which this explains all “oddness” of this little box. My point is that you’ve really found a cool little tape recorder there. I hope you enjoyed getting the real-life sailor experience of fixing Navy equipment. Also, the shoddy screws are likely from some sailor not being able to find the right part and using whatever was at hand. In the Navy we’d call that “gun decking”, and it would be court-martial-able.
I still have my interview tape from about 20 years ago recorded on one of these very good quality still. Fun fact if you asked for a copy they had to let you have one. And no i`m not a hardened criminal i was a teenager caught with a bit of weed :) You are correct about the label on one side of the tape mine is only labeled on one side.
Quick question about the synthesised time stamp... is it recorded on both tapes in the machine? Presumably it's there to prevent tampering/editing of the tape retrospectively, but it is my understanding that one cassette was retained by the police, the other would be given to the prisoner, so both had a copy. Not that much use to the prisoner if they didn't have the appropriate transcribing machine at home. Then again, I suppose it's still playable.
Maybe those erase heads are there because they were using some off the shelf tape mechanisms that had it... They just figured if they are always used to record to empty tapes, there is no need to connect it to anything.
I’m sure the timestamp system was implemented in some video recorders in use in certain countries’ TV stations: I remember watching a news item from French telly on the ina.fr website, taken presumably from a master tape recorded at the station (TF1 or Antenne 2, don’t remember which one precisely) while the programme was being aired. This is how most newscasts survive in archives as they were broadcast live. Sure enough, every so often a voice would pop up on the right-ear channel telling the time in French followed by a beep tone.
Very interesting. Remember when I was a kid my grandmother saved some (broken) old radios a camera and a cassette recorder for me to look inside and "play" with. I was about 7 years old and usually would beg her to rent a gameboy with a game. (I was 7 in 1990) But after taking apart my first radio I was hooked. Later on I became an computer technican and have been working with computer and repairing stuff pretty much all my adult life. Anyway, seeing theese older genuine constructions takes me back to my grandmothers appartment and me sitting under her kitchen table with the broken radio and my grandmothers old toolbox. (My grandmother was the best, she always said that true equailiy between the sexes is not about forcing women to change tires, it is to just let anyone have the possibility to be anything. And she said if I wanted to repair or just take apart stuff that was what I should do, girls did not just have to play with dolls. Now I am 35 and have three kids of my own. My grandmother sadly is not with us anymore, but I try to keep her legacy alive. I just bought some soldering kits for my oldest son and the arduino kits are amazing value, especialy when it is the kids trying to make things because they are not afraid to test things.
EXACTLY!!!!! We don't need special government-funded programs to get girls interested in STEM. If they're interested, then they're interested, simple as that.
Great video. Oh the memories of working on old cassette decks. It really was nostalgic to watch. For one moment I thought you were actually going to rewind that cassette with a pencil. Brilliant work. Thank you for showing.
Wow this was really interesting. I work for a company in Australia that makes and sells the digital interview recorders. It’s all computerised and the interview can be recorded for more than 12 hours on the machines. I find the cassette tape interview recorders more interesting.
Also you can’t just play them neither. You need to get decryption software that is compatible with the files. I don’t want to give out to much detail on what happens as that could jeopardise my job.

I guess the lack of rewind/ff/play is so you couldn't accidentally (or "accidentally") overwrite anything in the room.
Yes, All you can do in the interview is start the tapes rolling, then 'stop' if you need a break in the interview, normally if solicitor or suspect asks for one. At that point you stop the tapes and flip them open to show they're not being recorded as you leave the room.

@MoseyingFan loads of people had VHS rewinders in thier home because they were sold as being better for your tapes than the rewinder in your VCR. They were supposed to rewind as smoothly as your VCR plays or something like that to prevent wear on the tape.

this machine is built for a purpose instead of to a price point. so every part of it is top notch
Excellent observation!
Or, more cynically, the manufacturers knew they'd only be selling them to the government, so they went out of their way not to economize. :)
Exactly this. That's also the reason why it was heavily built with no plastic - because complete reliability was far more important than weight, looks or even price.
@@ZGryphonThat's good, it's a feature of government contracts and shouldn't be treated as a bug.
It's been shown time and time again in studies that government subsidised items since the mid 70s obsession with cost cutting have actually cost everyone more in ineffeciencies, breakages, accidents, and even death in some cases.
Governments commission quality products, everyone wins. They can do their jobs and we benefit from the government funded parts we can benefit from.
They accept the lowest bid for every contract because of "government excess" and the challenger disaster happens.

Police use or at least used for long tapes because the recorded tape is a clear physical piece of evidence and police have procedures to handle and store physical evidence. A recorded file on a server requires completely different procedures. While they can be developed it takes time and one cannot just ad-hoc create them.
That time recording on the other track was a pretty clever thing.
It also removes the chances of someone managing to electronically penetrate security, find the files, and delete or replace them. One could argue that if a police agency's data infrastructure is compromised, *_anyone_* could make such a change, but if it's stored offline on physical media, then there are far fewer people that are in a position to gain access to it to change, remove, or replace it.
*giggles* One could also argue that an offline server couldn't be breached, as proposed.
_"Whats that you say? A computer that isn't connected to the internet/a network?"_
A friend of mine who is a trained typist once worked for the Police transcribing interview tapes made using machines like this. She had to quickly learn the spelling of an awful lot of swear words.

Agree. Recording on a cassette tape is cheap and as physical medium it is easy to archive it without any information loss even for two or three decades. Digital medium is here not your friend. Big companies are still using magnetic tape to record their business meetings and conferences and also a lot data is stored on a computer cartridges with a magnetic tape inside.

Yep, how did I get from Laurel and Hardy to this? Another fine mess RUclips got me into.
yes it usually does
From an audio engineer and educator, I LOVE the walk thru! Engaging, clear and straightforward.
The ICM7212 at the front is just a display driver, likely for the minutes display. Date code on that is '89. The chip at the back is a Texas Instruments embedded microcontroller TMS70C02, which is the version without the on-chip ROM, so the 'LJv1.8' is certainly the software for it stored in an EPROM (or mask ROM - hard to tell). The other chip back there is the bus demultiplexer - nothing special. Date code on the TMS is also '89 - the ©1981 refers to the Texas CPU architecture I believe. It's certainly very solidly made - typical of 'good' British stuff made in the 80s, and the yellow capacitors throughout are classic ITT polycarbonate types which I remember well from the period. This thing is designed to be bullet-proof I'd say, makes sense ;-)
They had to stop making them in Britain; couldn't figure out how to make it leak oil.
And it uses a PCF8200 Phillips Voice Synthesizer
Oh my...benefits of watching in 4K?
Coni Glione Didn't you see the sticker behind the machine? The motor is made in Belgium but the whole thing was build in England.
had no connection to lucas, so the led's didnt fail.
as to the amount of ic's, the tech is overkill, are they doing something else other than syscon, are they adding some data to the tapes??
When using a bench supply you should set a lower current. Yes, it will only draw as much as it uses but if there is a short then limiting the amount of current it can draw is the difference between a repair and a fire.
Yes, but it might not be protecting a possible short.
Right. Setting the current just a bit above its normal operating current is a good idea. That is what I do. I used to repair cassette player/recorders (among other things) a long time ago.
How bout you make your own channel and do it yourself
Oh the memories! Our family firm in Hyde, Cheshire had a contract with Greater Manchester Police to repar these machines. They were built pretty well and were simple to service, and IIRC they came in single and double-deck versions. I think NEAL had connections to Wearite, who made domestic and semi-pro transports.
They likely only used one side of the tape, and made tapes with labels on one side, because flipping tapes runs the risk of flipping the same tape more than once and accidentally recording over side A.
Only using one side also means the erase head can wipe the entire width of the tape, leading to a lower noise floor.
I think it was a regular stereo-type head. When Techmoan digitized the playback audio, one channel was the audio, the other was the timestamps. So it apparently WAS possible to use the reverse side. I could see a procedure when flipping the tape in which it would be standard practice to break out the write-protect tab on the cassette to prevent such accidents.
Flippin' 'eck!
Nope, you didn't flip tapes or break the tab: instead you'd put the cassette back in its case and then wrap a large, signed label right around the case to seal it for evidential purposes.
James Plotkin Or it's a permanent magnet relying on the movement of the tape to generate a varying field.
16:46 Those timestamps could easily pass as "lyrics" to the song

Randall Waitt
The teak TEAC Teakmoan segment.
I used to work for Mastercare (aka Disastercare), Curry's in-house repair service. We used to fix white goods (fridges, freezers, washers etc) and brown goods (so-called because TVs and entertainment equipment used to have that woodgrain finish).
I was interviewed in 2017 three times in two different police stations and they were recorded on two CD-R's, and the recorder looked a lot like the digital NEAL one shown with two microphones. I remember during the interview I was more interested in the technology rather than the subject at hand! Standard CD-R's were used, I forgot which brand they were.
In the force I work for, we have custom printed CDRs, so case/custody numbers, exhibit references and interview start and finish times etc can be written onto the disc with a sharpie. Don't know who makes the media.
All my CD recordings have been falling like flies so we can infer the nightmare problem with these evidence records.
@@maestrovso yeah for sure. I would much rather trust a cassette tape for long term storage over a CD-R.
Those coppers will never take Techmoan alive!
I guess he did a good job convincing the popo that there was no struggle in that snuggle
And if they did, I guess him starting to fix their audio would catch them off guard and confuse them long enough so he could make a run once everything's working.
That is the oldest reference I have ever heard on RUclips Good job young man

Holy hell, 8 D batteries, is that thing supposed to power the ships engine!?
I agree! 8 to 18Ah @ 12v
To be fair, if you're in the middle of taking evidence in an interview you really can't have the batteries running flat... Mind - slightly surprised it needs 12V to run.
Wow! 12 V and 18 Ah is 216 Wh! That's enough to power my iMac Retina 4K at full load for two hours! I might buy some alkaline D cells as a backup... Just kidding, I'll just buy some LiPos.
@Dave F Didn't you see "12 V" in the motor label? Motors usually need that relatively high voltage compared to electronics.
Nah mate ships need at least 9 AA batteries to work ;)

Amazingly up till about three years ago these were still in use in the metropolitan police. The one you have is a portable for taking out the police station.

Its always good when "doesnt work" = "blown fuse"

"HMS" Ocean" was the first ship to use "Verbal Camouflage" When they wanted to hide important assets, they could just tell people the person or item was "On the Ocean", and the British military would know where that was, but no one else had a clue.
-This was another edition of "The Comic Military Speculation Text-Only Podcast."
Speaking of verbal camouflage... In my hometown, there were bars called "The Office" and "The Garage".
"Sorry, dear, but I'm needed at the office tonight. Tom wanted me to stop by the garage after. Should be home around nine."
Just as well Ocean was launched when she was then -- the old "that was on the Atlantic Conveyer when she went down" excuse was wearing a bit thin.
@@lordsummerisle87 "Atlantic Conveyor" has me thinking of a very long belt, starting at, say, Liverpool and ending at, say, Halifax, Nova Scotia.

Always interesting and as ever professionally produced. Thanks, Techmoan!
I'ts impressive how well is build inside and how bulky looks from outside. Made to last forever, solid state.

Those flywheels are HUGE and must give excellent pitch stability.
Makes me wonder if, with good heads etc, this might make the basis for a Nakamichi Dragon slayer. ;-)
Police are bad with kit, enlisted men are worse. This thing would have seen some real abuse.
...Possibly including the abuse that finally put it out of action: "Ah, those screws will do..."
wraithcadmus - I’d like to see it put through its paces. Tested for wow and flutter, frequency response, etc. but remember, this is a record only machine, no playback, and it is designed to record only on blank tapes. It’s no good at all as a hi fi component.
I first saw this type of recorder shown in an episode of „Midsomer Murders“ where it was used to interrogate a suspect in the Causton Constabulary (I‘m German I might add). You could see it was an interview recorder but they didn’t explain anything further, so thanks for providing this deep insight into this fascinating machine.
I can always count on Techmoan to have the best, weirdest, and most unique technology to show off with every single upload.
SPEECH SYNTHESIS ON THIS RECORDER??!!! YESSSS!!!! I love that! I love the sound of that synthesis; it sounds like it's based from an actual speaker originally. It sounds like they used linear predictive coding!
That is a really neat recorder, and built beautifully. The construction is truly a piece of art. Those flywheels are gorgeous!
The TI chip has 9011012 inscription. that stands for either 11th week of 1990 or November 1990. The Philips chip at 8:01 has very clear 9028 date code. Another chip under the front plate has 8912 date code. So that in total makes the machine assembled in the second half of 1990 or, maybe, early 1991 (although I incline to think that it was made about exactly 28 years ago, in September or October 1990).
And, well, copyright marks don't mean the year of manufacturing ever, period.
No, that is *not* the date code on the TI chip. The date code on that chip is 8913
The compartment with the three chips is interesting. The TM70C02NL is a 8bit microcontroller, the 74HTC573 is a latch which can be used as outputport of a microcontroller, and the "LJV1.8" looks like an Eprom. To the right of the TMS is a crystal oszillator. This is a small computer.
Oh. Some posted that already.

@@sicktunechaser Nope, sorry!
The next time you want to drill out a screw, please use a left hand drill bit instead of a normal right hand drill bit. A left hand drill bit works counter clockwise, so if the screws catches in the drill bit, out it comes.
If you use a screw extractor integrated drill bit it's used anti-clockwise for the very same reason.
You’re right, but why buy a set of them for what could well be a one time only job? It’s not like it was a machine screw that was going to be a pain to extract, just a self tapper that needed to lose its head and meet some pliers. I think he did well enough with what he had to hand.
See @4:55 when he says, "As always happens, you get to the last screw, it doesn't want to come out, and it strips." This indicates that he has disassembled stuff before.
And, at @5:40, we see that the screw is right on the circuit board. So, if the screw had gone in, it could have destroyed the circuit board.
If you look at Amazon, a left hand drill set goes for $10 USD (ref: amzn.to/2CW0lj1 ) for a cheap set. @Techmoan seems to do plenty of equipment refurbishments.
Mark Holtz - Well, it’s certainly the proper way to do it, no argument there! He maybe could have got hold of the head with pliers and turned it out, or slotted it with a Dremel cutoff wheel and used a flat blade screwdriver to get it out, etc. That would risk damaging the case, though. Sometimes the Ghetto way is more interesting, if not ‘correct’. :-)
+Gernot Schrader Well, yes it "worked" if you consider digging a divot into the aluminum case a proper solution...these days, a set of left-hand twist drill bits is quite inexpensive -- even using a Dremel tool to cut a slot is a better option than what did...and why is he at first unsure of date of manufacture, then later he mentions in passing the late 80's codes on the microchip packages?
Testing a fuse? Drilling a screw out? That's next level stuff Mr. Techmoan! Congratulations!
I like that "Thieves are Watching YOU" sticker, with the Peter Capaldi Doctor eyes. Just thought I'd point that out.
That is a really neat device. I have done work designing and installing the equipment in "interview rooms".
Interesting with the time-stamp on the other audio tracks.
Official Air Traffic Control audio recordings have this as well, it's not a voice synthesizer, it sounds like a bunch of loud static - it's an encoded machine-readable timestamp that takes up the second audio track.
I have listened to many hundreds of interview tapes on transcript machines over the years and I always assumed that the time stamp was added by the transcript machine, not recorded on the tape. Of course it makes more sense now that I know! The transcript machines also have a speed up/Slow down feature and you can adjust the balance to fade out the time stamp. It would be great to see you get hold of a transcript machine, the ones that we used were slightly different to the one you showed on the video. Great Video. Thank you.
I wonder if the puppets have ever had a run in with the police 🤔...
Should use this to stage an interrogation of the puppets in which they're 'verballed' into admitting to a crime they didn't commit!
I'm not sure if their collars have been felt, but the rest of them is.
I like the puppets.
The Texas Instruments chip is a microcontroller from the 80s. I wouldn't be surprised if the speech synthesis in the unit is handled by some TI chip as well. They were leading the market in speech synthesis back then.
15:44 ... "Hello, Scotland Yard? ... Inspector Jobsworth reporting, I think we've finally identified the suspect."
12:57 - Yeah that loud, long beep sound when commencing recording is shown on basically every British police interview tape recorder usage on fictional dramas and real-life documentaries alike. As well as being used to get past the lead-in, it was also probably useful for functional reasons because it gave a totally unambiguous and unmissable signal to officers, suspects and lawyers that recording had commenced. It also worked as an interruption and reminder for the officers, suspect and lawyers to stop talking while the noise was happening, so there was less risk of the actual recording commencing with someone mid-sentence and there being any future ambiguity in court about what was being said or intended.
Nice, That recorder has some serious history!
I'm absolutely fascinated by these old machines, there were some kind of magic in the ingenuity of these equipments.
The inside of that deck has some very high quality components-that large blue capacitor for one and the toroidal transformer.All the wiring is very neatly cable tied which is very similar to the inside of my naim audio gear
I have had a few interviews on these. The voice is called a “chinaman” I was told by a policeman! They are supposed to beep for a few seconds after switching on.
That's a rather specialized recorder. Serious capstan pulleys though.
They act as flywheels which help reduce wow and flutter.
I was surprised at how much I enjoyed this episode. Thanks!
Seems crazy that they'd use a solenoid to pull the heads down instead of making it mechanical. I'll bet it really sapped the batteries.
The batteries were to be as a sort of UPS, not to run it. [another poster]
Reliability will always win against power consumption. And solenoids like these are way more reliable that mechanical parts that usually break pretty easily. And that thing actually runs plugged in, not on batteries.
I see, so it has batteries to run plugged in. Surely the batteries are for a power option and not just to make the unit heavier.
Wow, that voice synthesizer is really clean sounding!
The beeping is a built in torture feature to maximize the effectiveness of the interrogation.
This looks very much like “mil-spec” hardware. Remember that these kinds of things were purpose build for military use. Although I don’t know for sure about The Royal Navy, as a former USN technician I worked on all sorts of electronics like this.
It’s build to withstand poor power quality, rough seas, must be able to be trouble-shot and fixed at sea (in rough seas too), handle salty and humid environments, and whatever else war and sea-duty can do to it. Which this explains all “oddness” of this little box.
My point is that you’ve really found a cool little tape recorder there. I hope you enjoyed getting the real-life sailor experience of fixing Navy equipment.
Also, the shoddy screws are likely from some sailor not being able to find the right part and using whatever was at hand. In the Navy we’d call that “gun decking”, and it would be court-martial-able.
I had a Koni Omega medium format film camera - they were used by the Royal Navy.
Looks like a well thought out solid piece of kit.
Yes it is almost MIL spec.
It needed to be idiot proof for obvious reasons :)
I don't think I have electronics from this decade that are that clean inside. That thing was spotless.
I have been recorded by one of those. Not my proudest moment.
And I bet it sounded like, "Me me ME ME me meME mememe..."
Haha, me too. Whoopsie!

I feel that. Still awaiting court. Its killing me.
Sitting there rambling into a microphone is something I could never contemplate techmoan doing...
I still have my interview tape from about 20 years ago recorded on one of these very good quality still.
Fun fact if you asked for a copy they had to let you have one.
And no i`m not a hardened criminal i was a teenager caught with a bit of weed :)
You are correct about the label on one side of the tape mine is only labeled on one side.
Quick question about the synthesised time stamp... is it recorded on both tapes in the machine? Presumably it's there to prevent tampering/editing of the tape retrospectively, but it is my understanding that one cassette was retained by the police, the other would be given to the prisoner, so both had a copy. Not that much use to the prisoner if they didn't have the appropriate transcribing machine at home. Then again, I suppose it's still playable.
Maybe those erase heads are there because they were using some off the shelf tape mechanisms that had it... They just figured if they are always used to record to empty tapes, there is no need to connect it to anything.
I’m sure the timestamp system was implemented in some video recorders in use in certain countries’ TV stations: I remember watching a news item from French telly on the ina.fr website, taken presumably from a master tape recorded at the station (TF1 or Antenne 2, don’t remember which one precisely) while the programme was being aired.
This is how most newscasts survive in archives as they were broadcast live.
Sure enough, every so often a voice would pop up on the right-ear channel telling the time in French followed by a beep tone.
15:38 That's beautiful! It's a perfect background loop to vaporwave compilations.
+Techmoan, you just interrogated a RUclips soundtrack! :P
Very interesting. Remember when I was a kid my grandmother saved some (broken) old radios a camera and a cassette recorder for me to look inside and "play" with. I was about 7 years old and usually would beg her to rent a gameboy with a game. (I was 7 in 1990) But after taking apart my first radio I was hooked. Later on I became an computer technican and have been working with computer and repairing stuff pretty much all my adult life. Anyway, seeing theese older genuine constructions takes me back to my grandmothers appartment and me sitting under her kitchen table with the broken radio and my grandmothers old toolbox. (My grandmother was the best, she always said that true equailiy between the sexes is not about forcing women to change tires, it is to just let anyone have the possibility to be anything. And she said if I wanted to repair or just take apart stuff that was what I should do, girls did not just have to play with dolls.
Now I am 35 and have three kids of my own. My grandmother sadly is not with us anymore, but I try to keep her legacy alive. I just bought some soldering kits for my oldest son and the arduino kits are amazing value, especialy when it is the kids trying to make things because they are not afraid to test things.
I was always taking old things apart at that age, cooker isolators, reel to reel tape recorders etc.
Just great. My wife and daughter is just as handy with a screwdriver than any man / boy (me included) Thanks for sharing. BR, Per (Denmark)
I absolutely love your grandmother's, and your, attitude. It strikes the right balance in presenting experiences and choice.
EXACTLY!!!!! We don't need special government-funded programs to get girls interested in STEM. If they're interested, then they're interested, simple as that.
Fascinating tale, glad to hear you followed your dreams
Great video. Oh the memories of working on old cassette decks. It really was nostalgic to watch. For one moment I thought you were actually going to rewind that cassette with a pencil. Brilliant work. Thank you for showing.
Wow this was really interesting. I work for a company in Australia that makes and sells the digital interview recorders. It’s all computerised and the interview can be recorded for more than 12 hours on the machines. I find the cassette tape interview recorders more interesting.
Does your product record if someone is randomly cut in pieces in Saudi embassy?
Mika Korhonen Pretty violent but yes it can record that.
How do the digital recorder stop someone editing the recording in Audacity ?
MrDuncl Good question. The recording files are encrypted. You can’t just open them in Audacity you need to decrypt the files first.
Also you can’t just play them neither. You need to get decryption software that is compatible with the files. I don’t want to give out to much detail on what happens as that could jeopardise my job.
I was going to say that was a lot of microchips for a simple tape recorder. The voice synthesizer explains it. That intel speak and spell chip
The beep to indicate start of the interview when it goes silent
The Techmoan channel continues to be one of the best content producers of ANY genre. As a musician and defacto home recording engineer the obsolete music platforms, analog technologies and rare gizmos TechMoan features are beyond fascinating to me...the editing & presentation has always been good but the angles showing the inside of this unit were so cool. Well done as usual...
I'd definitely use isopropyl over soap, soap leaves a residue.

I was introduced to it by a friend who had his TV and electronics repair shop in London for decades. So much better than meths or white spirit! It leaves no (visible) residue. I looked up PHI in Falmouth - still in business. My first tape recorder was a Grundig TK5 - in 1956.
