"HAVE YOU THOUGHT ABOUT BUYING STAMPS TODAY?"
Aye no, I'm at the post office to get my hair cut.
The fact that they've used Iron Maiden's "Number Of The Beast" as the ideal gift - excellent. And supremely 80s Britain.
Hehe, yup. That would still be the ideal gift for me today!
Yep, and now the Post Office have come full circle by recently releasing Iron Maiden commemorative stamps. I think they are only the fifth group to be commemorated.
Ya beat me to it. Seriously though, showing a young fellow holding a flippin' Iron Maiden album is hilarious.
with Christopher Reeve buying it
I was a bit surprised, I wouldn't have thought Maiden was accepted as a good and proper thing in that "official" sphere yet.
In the mid 80's I worked as a security guard at night in a retail store being built in a local mall. The music system in the store was so accurately repeditave I could eventually tell the current time by the song playing.
I like how Matt's long search for a 60Hz inverter that works properly with old audiovisual gear has finally competed successfully
It's such an obvious solution in retrospect!
With a bigger battery, Matt could continue producing weekly videos after the collapse of modern civilization.
I feel like a sponsorship is in order. I hear they pay pretty well. Do a review matt !
BTW, i still love your outro song!
I also love how it's not an inverter at all XD Sometimes the right tool is the thing you weren't looking for 😄
@@allenellisdewitt It really isn't that easy though, his previous attempt discovered that Ryobi's "pure sine wave" inverter was anything but.
Well Mat, you've inadvertently solved a 50-year mystery for me! The quick succession of slides about Ernie and premium bonds helped me decipher just what Ian Anderson meant by the line "Saying 'how's your granny and good old Ernie, he coughed up a tenner on a premium bond win' " in "Thick as a Brick". Being in the States I had no idea what he was talking about so this quick bit of your video prompted me to Google Ernie and premium bond - and there was the answer! I had no idea the Ernie being referred to wasn't a local chap down the pub, but the acronym for the machine generating the numbers for the 'lottery'! I'll bet nobody else had a connection from this video to Jethro Tull on their Bingo card!!!! Thanks and great job as always!
Glad I could help.
ERNIE == Electronic Random Number Indicating Equipment
.. And he drove the fastest Milk Cart in the west!
@@EzeePosseTV I thought it was Irving....
Edit: Never mind. Got two different songs mixed up in my head.
@Techmoan I knew you were a fellow Metokur fan 😂
We'd LOVE the story on your friend's pirate action movie business
I agree, must be an interesting story.

Pretty sure it was a guy with a mail order business. Not a friend.
Importing a US portable battery with 60Hz AC output was a stroke of genius.
someone did forced that on him
So, he could import a Li-ion batt, but not an inert, obsolete, portable, rear projector? Bureaucrats!!!
@@pvman2 More likely the export paperwork wasn't filled out correctly. CBP is pretty anal about their paperwork and filing. They won't let an item through because they don't understand it and think it's prohibited, but if you call it an "engineering sample" it will get through no problem. This is how a lot of test and computer equipment gets through. If I want to ship half a dozen circuit boards to Australia for example, I could list what they are and what hazards they may have (simple don't put a CR2032 battery and you can list 'none'). But if the boards are just tough pressure sensors for recording overpressure events up close, and you call them "explosion sensors", there is a good chance the word explosion keeps your items off the plane.
Thats just an example, there are far less ridiculous names that have kept things stuck in customs.
Sounds like the shipping would cost more than just importing an inverter without a heavy battery already attached.

"Reinventing the reel" would have been the perfect advert for the micro cassette! XD
The color fading is typical of Ektrachrome compatible film (which also includes things like Agfa and Fuji).
Kodachrome typically is immune to fading. That process is unique to Kodak and required massively complex equipment to process. It's interesting to note that Kodachrome is actually a black and white film that has layers dyed during processing and it was invented by hobbyist chemists Mannes and Godowsky in Mannes' kitchen. Their day jobs were as professional musicians.
Yes, Kodachrome is more or less immune to that, but Ektachrome suffered from it a lot, so did Fuji. However Agfa and 3m film held up a lot better, not quite as excellent as Kodachrome, but close!
I think it is Eastmancolor production prints what fades so heavily. Ektachrome et al too, but not so extremely like the Eastmancolor mass production prints of that era.
Do the faded films have enough color remaining to be able to digitally resurrect them?
@@lunquewill Pretty much anything can be done with digital tinkering nowerdays. If that's also authentic then is a different story, I consider any but the conservative methods as botch. (That opinion of course doesn't apply for heavily damaged but highly valuable material that needs to be resurrected at any cost.)
@@lunquewill They say at least ca 4% of original dye density is necessary to fully restore the colour.
Back in the 80's my grandfather worked at a tractor dealership and brought one of these systems home. It was meant to demonstrate how to repair the new equipment coming out on tractors. It was pretty cool because you could have the part right there in front of you and it was like a step by step guide to work on it. As a kid I watched all of the tapes and it really helped me understand a lot of mechanical systems that could be applied to cars, trucks etc. and helped spur my interest in working on cars
An analog UA-cam tutorial 🤪
iFixit of the 80s.
My father worked for Amtrak when I was a kid and taught training classes for the mechanical department, meaning we had a few boxes of very technical VHS tapes in the basement at all times. I spent hours and hours watching all the hits like "Locomotive air brake departure test" and "Introduction to Head-End-Power". Knew more about P42 locomotives than anybody else in elementary school.
aaand fastforward to now where your not allowed to work on the tractor you own and bought.
But now the same manufacturer which ensures you understand you do not own anything and will be happy.
I really like that slide changing mechanism. There's just something about the quick smooth movement and the little "swish" that appeals to me. Tickles the same part of the brain as when something is cut perfectly or perfectly fits into a socket or something.
it would be a great transition to have on modern presentation software!
It's the auditory equivalent of the scissors gliding as you cut wrapping paper.
It looks like a special effect, but it's just the film advancing. And I guess Labelle was too cheap to have any sort of blanking mechanism for when the film is in motion, or maybe they realised it looks better this way.
I like how it fails. That warbling noise is neat o
I'd never thought of that before...how nice it sounds... I mean with the daily use of slide show machines these days 📱💻 but hearing the mechanism perform is glorious.... I'm kinda scared now to see how many ASMR videos cover slides or something similar.... Might be my new sleeping partner. 😴🤤😴🤤 Great video as always! Have a wonderful day everyone! & Smile! - it makes everyone wonder what you're up to!! 🍻🌎❤️🌮
I remember when I was a kid, a saleslady for swimming pools came to our house and had a self-contained slide show unit like this for her presentation! Very exciting to see, but my parents never did buy that swimming pool.
Hello: I am a very old man from Patagonia, Argentina. We did not have those equipments but you remembered me when I went to the local and huge postal office back in the 60´s and 70´s. I thank you for all in your channel. Cheers!!!
Mr. Techmoan really is the Indiana Jones of technical oddities. It's always great fun to join him on his adventures. :)
Greetings from Germany
Germany gave us one of the devices that truly made this channel famous for its oddtech audio formats. the Tefifon.

Matt, you always manage to make the ordinary, mundane or otherwise arcane vintage tech utterly fascinating with your affable and engaging presentation approach. Kudos Mate! 👏👏
1:31 "...at one of the elbows of the zig-zag..."
Whenever I've been in a ziz-zag queue, I've wondered about the proper name for the 180° turns at the ends. "Elbows" - another mystery solved. Watching Matt's videos, every day is a schoolday...
Units very much like this one were common in the United States back in the Seventies. I would see them most often at those enormous Home Show, Camping Show, and other large-hall exhibitions. Salesmen of all types would set one up on a table to attract potential customers. Of course, it also drew in tech-minded tykes like myself, eager to figure out the inner workings of this odd beast.
I also remember seeing these running little info sessions about exhibits in museums when my family was driving around the US & Canada in the late 70s.
Sounds exactly like me.
Hey Matt, if you decide to fix that unit up, double check that there is no DC Voltage across that volume pot. If there is, it makes that crackling much worse and it has a bad blocking capacitor in it. Fun video! Thanks!
It's also possible that the carbon (it WILL be carbon!) track inside the pot has either "come off" or simply been worn away over time. In which case, replace the pot (DUH!).
I've run some of these for National Savings. My friend Chris Squires of savethosememories scanned the cine film and I ran the 8-track part, then we stuck the audio and video parts back together. I've mentioned this on my channel a while back.
I had a history teacher in 2004 that was still using these to supplement lessons about the American Revolution. It was mostly illustrated and narrated folklore. I *distinctly* remember how pink the slides were.
Matt is a cultural historian and as a nation we should acknowledge his hard work and effort. Amazing documentation not just of technology but the very time it was used in.
The 70s cartridge was made 6 minutes from my house. Absolutely surreal to see that address on Techmoan.
In the mid 90s the large company I worked for (you’ll know them if I mention them) trialled a more up to date version of this. Computer monitors in every branch with content transmitted overnight via modem. I was responsible for putting together the slideshows.
We piloted it with about six stores. I quite enjoyed messing with the system and trying to make it creative. But the library music they gave us was the usual guff and, despite my best attempts, it was difficult to make it anything less than irritating.
The six trial branches immediately turned down the volume rather than go crazy and the resulting silent shows soon got covered up with stock.
Fortunately I’d been reading about a new thing called the worldwide web and began experimenting with it. Bye bye remote AV system
I was thinking, I can remember these in the 90s, and I'm sure they had the word Video something on the plastic cabinet and I think they were CRTs rather than a projector. They were very irritating, and didnt last long
Did that World Wide Web ever take off then?
@@Demiglitch the jury is still out
I just gotta say I really love the unique look of super high-detail 4K video recordings of inherently low-quality film slides. It's a juxtaposition that I consider a rare treat. Like seeing an old favorite film that you used to watch on VHS or whatever, but somebody went and found a film print and decided to make a 4K bluray out of it.
As a Midwesterner, I’m very interested to hear Mat try to pronounce “Oconomowoc, Wisconsin” where La Belle Industries was based!
Or Wayzata.
I used to be in the Midwest and had to look that one up! Wayzata too.
AWK-On-omo-wock
Is my guess - like oconomowalk
Had to read it a few times but to me it seems like it prolly sounds just like you’d expect. Close?
I never happened upon one of these in my youth. In the '80s, my semi-rural town was slow to move to videocassette, but we still used filmstrip projectors in school. However, the film side of this reminds me a lot of the endless-loop video cartridges that Fisher-Price sold as a children's toy.
I’m surprised we didn’t have something like this in my elementary school in the early 90’s. Our library would show a lot of film strips which were a much more rudimentary version, usually accompanied by a cassette tape with an audible tone to advance the film strip.
I suspect it came down to cost. Film strips were older, but the projectors were sometimes more recent. The older projectors used a record for the audio, the later ones used a compact cassette. The format having been around longer meant more content available, particularly since neither the audio nor the film technology were proprietary, which this was. Most of the projectors at my school were Dukane, so I suspect the Labelle projectors were more expensive, and this fancy format, being marketed to business, was more expensive still. And of course who cares if it's more work to set up, it's just a teacher doing it, not an important businessman. (sarcasm)
Hey Techmoan, you're a genuine historian and archivist dealing with this stuff. I can only imagine there are hundreds of historical business presentations that would be lost forever without people digitizing them
They had one of these in our school library in '84, and later I saw a similar format at a driving instructor, although it had been replaced by a VCR and was just left standing there.
That's where I remember this from too! Although I saw one sometime in 1997 or 1998.
LMFAO at the quick flash of N'Sync, a little sneaky clip.. Too funny.. What's amazing, I actually found one of these at the Thrift Shop yesterday.. I was trying to figure it out then magically this video happens. I found a rear projection unit.
I remember these in school here in Colorado... It was used for supplemental content alongside the VHS tapes for Voyage of the Mimi. Never thought something would bring that back to my mind from 1985!
Voyage of the Mimi, lol. Did you also see Tomes & Talismans?
@@herbiehusker1889 Nope. Read the plot on the Wikipedia page, I'd definitely remember that one, even all these years later! XD
@Ikadzuchi too bad. It was good, just like Voyage of the Mimi.
VOYAGE OF THE MIMI HOLY SHIT MY BRAIN
Wow.. You were in a fancy school system. We had regular film projectors and a compact cassette tape to accompany them and person (usually a student) would have to manually advance the projector every time the tape would BEEP...
Then again, we also had Betamax players, so maybe my school system just made bad financial decisions. 😆
When I was in elementary school in the early '70s we had a similar educational AV system called the Ealing film loop. It was a cartridge with an endless loop of film which probably used normal sound-on-film for the audio. However, because it was a loop, it used a mechanism similar to the 8-track that pulled from the center and rewound on the outside. I was in the US, but I think Ealing was a British company.
We had these, too. They were developed by Technicolor (a US company) and called the "Magi-Cartridge." There are 8mm and super-8mm versions of it, and the cartridges are (smartly) designed to not fit the wrong type of projector.
The archived material actually looked quite good. It’s nice that it used projector styled metal belts instead of the rubber ones. Those seem to last forever.
8-track carts were used until the mid 2000s on Japanese buses and trains in a similar way. The "TAPE CONDUCTOR" the bus driver would press a cue button and the bus stop would be announced. Narration on one track and tones on the other, but at half speed. I have some that are dated 2005 and 2006. I repurposed some of them into custom quadraphonic tapes of new surround mixes. I always enjoy your videos, thanks.
I love your channel so much Techmoan. I grew up in the 70's/80's. and your channel warms my heart with nostalgia and technical retro knowlege. Thank you.
I also like his channel but I am younger and also a Swede, I like to learn about retro tech. Technoman have a wonderful voice.
It’s interesting how his latest videos already feel nostalgic to me. I’ve been watching this channel for a few years now and on each video, the outro makes me tear up in nostalgia…
As a music producer, I am constantly sampling the beautiful, vintage speech bits you play. As an audio engineer, I appreciate the wild variety of audio sources, mic angles, and occasional wobble, because there's no end of fun in resampling them later.
Also, as an American, I had to go back and listen to you say "tutor" several times before realized that you weren't saying it wrong the first time, I was just hearing it correctly. Thanks for another gem!
Ive heard sampling of vintage speech bits more and more in the music i hear.
Is there a word for this practice?
@@alittlebitintellectual7361Laziness.
I love the aesthetics of the graphic design for the post office slides. looks awesome.
I like the idea of Aerogramme.
I often sent a bi-fold post card here in USA, you write one half fold it over, and they reply back, with the other, Pre-stamped postcard Attached. (Businesses could print the pre-addressed return, so they didn't send the reply card to Aunty Matilda, instead.😂
When you said "Commpak" I heard "Compaq" first and thought we were about to enter an even more extensive rabbit hole of computer history
This is a very timely video! I just found one of these systems in the woods inside an old van. Next to it was Taco Bell training media. I had never seen or heard of this even though I grew up in the 80s. Thanks for showing how it worked!
I love that little "swoosh" sound between slides, it adds some character and also brings nac your attention because you know that every time you hear it there's something new at the screen to look at
I would say that these probably were turned off by the staff, because they likely complained to the union that they were very likely to go postal, with this repeating 24 times a day being deemed to be torture. By me the post office only had large LED displays, often only showing vounters in use, and wrong, plus the most common thing shown on them was the "Welcome to Polycomp, the date is xx/xx/xxxx, the time is yy:yy:yy, the temperature is 56C, data corrupted" as there was little chance that anybody there actually knew how to program them, and more importantly, nobody would have either the wired keyboard or IR transmitter that you needed to program them. The later ones used a Palm Pilot and software to build up the display on the Palm, and then send to the display using the IR port.
@@Rick_Todd
I was thinking that! In fact I'm sure that the one in our city post office didn't have any narration so likely the staff had turned it down or even snipped the speaker wires so no one could turn it up again!
I used to love those LED displays, there were even large ones on the streets, amazing how they're now delightfully obsolete
@@Rick_Todd Or someone using a screwdriver on the speaker.
@@Spudcore I have no idea when those started here in the USA, probably at the same time or 2010s we have video ads at gas stations but you can turn off the audio
I absolutely love the sound the machine makes when awitching slides. It hits that geeky love for quiet electronics noises.
I really enjoyed this one. I'm amazed that you keep on finding these new/old AV formats to present.
I remember reading that 8 track tapes were used for continuous playback in malls well into the 90's before being supplanted by internet radio. They were also used for event recording on trains (similar to a black box in a plane) even more recent than that from what I've heard
On films that have "Cyan Fade" you can put a blue gel filter in front of the lens of the projector and it will somewhat restore the colors.
Sounds a lot safer than my idea of submerging the film in a diluted blue permeant marker and alcohol solution.
Come to think of it I have no idea what alcohol would do to the film itself.
I've often wondered how old films are restored when they look like that with the cyan and yellow fade and not much of those colors left. Somehow they must do a digital version of adding the blue gel; but turned way up with digital tools. Amazing, how much full range color they can get back from old faded color film.
Or send it over to Fran Blanche 😉- she's made color-corrected video transfers from several 70's era NASA films.
From what I heard (I may be wrong), it was a result of films using "Eastmancolor" for their colour layers which (IIRC) was cheaper than the "Technicolor" system but the cyan and yellow pigments would fade out over time.
@@marcusdamberger When films are restored they go from the original negatives rather than faded prints, only using those when the original neg materials are lost. Even so, using digital tools quite a lot of colour can be drawn out of faded film, depending on how faded it has become of course.
I too have stood in that same post office in central Manchester back in the late 80’s and saw the same display!
Seeing this in the 70s/80s on a back projection screen must have looked pretty amazing, so much higher res/quality than a VHS!
I seen to remember a similar device to present Disney stories, including a kid-i-fied mobile presentation projector. Early 80s late 70s, bit it may have been older than that.
What a charming little story about a format I would otherwise not have noticed. Enjoyed this episode.
The music at 21:10 is very Boards of Canada sounding, realy cool
"To buy what you want" - Iron Maiden's The Number of the Beast album? Hell yes!
This odd format has two interesting add-ons for me. One was the Jethro Tull comment about ERNIE (as I am a long-time Tull fan) plus La Belle Industries was based in Oconomowoc, Wisconsin about 15 miles from me. Didn't expect that one!
Every time I watch a Tech Moan video, I feel like I've learned something I'd never have had the chance to know about. Thank you!!
17:40 - 'cartridge for use by purchaser only'. The first 'copy-protection' notice ever used?
Old school piracy stories are always awesome, a guy was telling how they released amiga/atari st games back in the 90s, it's so interesting. (I think it was on the retrocave youtube chanel) reusing old stamps, sending letters with a fake adress but the good return adress and so on ... lots of fun.
That brings back memories of reusing stamps by sticking tape over them so the recipient could gently peel it off and remove the inked postal stamp thingy. Did this many times when posting pirated Amiga games to other users who did the same. Suprised the post office never got wind of the trick but I guess as it was all automated it wasnt worth the expense and hassle of checking for clear tape.
@@meetoo594 That sort of trick is why the new stamps all have a unique barcode, each code can only be used once.
Fantastic video. I remember seeing such slideshows whilst queuing at the Post Office well!
I’ve never seen these thing here downunder which is surprising to me since we tend to get gizmos of all sorts in the later years of it’s production as per usual. I mean it’s still like that today tbh, especially electronic devices like this.
Interesting device, vnoicely done & ty Mat👌🏼
There used to be something like the Showman 16 rear-projection unit set up at our local hardware store (Rickel Home Center in NJ) when i was a kid in the ’70s that constantly looped a demonstration of some cleaning product. I’ve long since forgotten the name of the product, but the guy in the video repeats several times “Remember, it’s the _foam_ that does the work!”, and i HAVE remembered, to this very day 😆 Wish i could find that video somewhere, but haven’t been able to so far… though Mat unearthing things in the same family gives me hope 😋
I wonder if it was for Dow Bathroom Cleaner both because it made a big deal of the 'scrubbing bubbles' and also because you could see Dow Roofing made several of the cartridges in the first ebay auction.
I remember being subjected to one of those in a post office.
I'm so sorry for you. I hope you're doing alright now. 😉
@@EvenTheDogAgrees I recovered.
@@58Brando I didn't. I still have nightmares!!🤣
I remember using something like this in the late 70s in school, but it used a separate compact audio cassette and a film reel. And the tone to switch slides was mixed with the normal audio. This actually looks a lot more advanced in some ways.
I remain amazed that you continue finding more formats to show to us. I was thinking that you were going to fix the speed issue by recording it and speeding it up in post, but I suppose running the machine at the wrong speed for an extended period might damage the media or the machine itself
This is my favourite kind of content from you: an in-depth analysis of some highly obscure audio-visual device. I had no idea these things existed. Thank you.
Fascinating! I am only too aware of the "colour-fade" problem on 16mm as my business includes selling 16mm movies! I really enjoy the way you appreciate technology in the context of the times! Best regards Keith
Am I correct in thinking that they still used potato starch to help fix the colours during thar era ?
•Kodachrome (K-14?)never fades...alas, it was expensive, multistep process involving harsh chemicals. Only Kodak, and Life Magazine knew the process.
•Kodak's E-6 Ektachrome was quick, (relatively) safe and could even be processed by amateurs, in their home darkroom.
•I was a US Navy photographer, and we had to send our archival Kodachrome to KODAK, but, shot routine short shelf life projects on E-6 slides.
@@bagofnails6692 that would be really cool.
The Kenosha History Center, a museum in Kenosha WI, received a donation of a large collection of these and two players. Ours are American Motors training material. Unfortunately, the 8 Track player component of the players need new belts and we don't have much free time to spend replacing them. They instantly reminded me of automated slideshows with sound in school in the 1980s.
Oh wow, that'd be great to see. Belts are the bane of this stuff.
Fascinating and very nostalgic. 🙂
That a weird A/V format i never knew existed. Bizarre and fascinating. PS: A friend of mine knew one of Mr. Lear's daughters she was named Crystal Chanda Lear. (really)
2:46 Wow, even helped with arithmatic. How nice of them.
Btw, Sir, you are brilliant. Over the years, being from the US, I've just delt with 50cycle stuff and digitized it, then sped it up. The thought never crossed my mind to simply pick up a battery backup source from the UK running at 50Hz in use that as my Hz converter. Thank you!
10:58 That recording sounded a lot like David Niven!
Thoroughly enjoyed this . Thank you.
It's going to be cheaper to pick up a 12V power supply and UK inverter if you don't actually need the battery.
@@jonc4403 Indeed. Very good point.
Interesting to see someone's idea to combine two different technologies into a product that had an unfortunately short run, but useful in business and advertising.

In sync... loved that... how many either missed (or saw that ) bravo Matt
If only VHS was endless looping that would have been awesome no more "be kind please rewind"
Great video as always Matt.
Seeing stamps for TV License and Road Tax brought back memories of my parents buying these each month before direct debits took over.
I had the same Flashback when a saw those stamps :)
I’d forgotten about those!
Ten stamps for £1.30! We're not far off £1.30 per stamp these days
@@nwr99nwr99 Factoring in inflation, that £0.13 should now be only be £0.52, so the real price of the stamp has doubled --- most likely due to the increasing cost of delivery by humans.
Remember those systems in use in Dutch museums back in the '70s and '80s. But never knew how it was operated. Thank you for showing.
I've been watching your videos for a good number of years now, and I just wanted to say thank you for all the content you've made. Informative and very funny. It's brought me happiness.
Thank you for sharing yet another relic from the past I didn't know existed. The device in action certainly has some THX 1138 vibes 🙂
Some really interesting stuff. I am sure I remember these from the post office in the late 80s. They were always too loud and the staff could not turn them down
Just imagine Mat doing a podcast, telling different stories about life, technology, people (dodgy Kev Etc…) I would LOVE for something like this to happen and I’m sure I’m not alone! Love the videos and have been a dedicated follower for years!!!!!
I've never seen it and I still got nostalgic vibes.
I remember these machines were used in my school when I was young.. I recall watching a couple of educational presentations on similar machines back then.
I remember stamps being nearly that cheap, i'm not sure if I remember if we had one of those machines in my local post office.
These were at the local library into the late 80s/early 90s. When you checked one out you also got a small portable rear projection player(shaped like a loaf of bread with a screen on one end). The first few reports I wrote in elementary school were researched mainly with these. I can still remember most of the one about meteors and asteroids.
10:47 "But did you know that ℌ𝔈ℜ𝔈 at your local post office..."
Yeah, weird pronunciation of ‘here’.
Saying how this was the right tool for the job despite being outdated at that time sounds very much like how certain airlines around the world still fly pre- or post-WWII propeller driven aircraft or first generation jets, because they're extremely reliable, made to do heavy work, and can still get to places no modern aircraft is capable of. Excellent video as always Matt!
I think our veterinarian had one of the suitcase viewers in his office. Don’t think I ever used it though!
Fascinating stuff, Mat! ❤️
The flash frame N Sync still image is much more wholesome than the similar subliminal frames in "Fight Club" that doubtless inspired it...
Really smart way to solve the 50/60 hz problem, Matt! I would have liked to see more about the film advance mechanism. How did it align each slide and prevent or fix misalignment? Was it a sprocket or pinch roller design?
You've unlocked a memory, there was one in a UK post office I used to visit around 1990-1991. Not sure how much longer it was in use, as we moved away in '91 and that was the last time I saw one.
Funny enough, databits has just recently released a video about a rather similar proto-power-point thing
That's what I was thinking, what a coincidence
Never seen this Audio/visual contraption before. Spent almost a half hour watching a documentary about it. Techmoan is like when the teacher in grade school showed us a Jaque Costo documentary film in class and you thought it was gonna be boring, but it turned out to be the best class of the day.
It wouldn't surprise me if the post office staff just subconsciously tuned it out after a while. I worked in a bank which had a very loud ATM in it's front wall with it's back exposed in the customer area inside. Customers would comment on how horrendous it must be hearing that beeping all day for every key press on the machine. But no, the staff didn't even notice it after a day or two working there. It's amazing what the brain can filter out.
Worked in retail with a digital display that loudly played advertisements for LG. Can confirm, you do mostly tune them out, although one of the ads always broke through that mental filter. Was glad when we finally stopped selling LG products, lol
Matt is a national treasure at this point
Wow, Bell County High School, in Bell County, Kentucky, used these for sex Ed and home ec classes until mid 2014 when they finally got the big upgrade to that sort of curriculum in the form of, wait for it, a commercial laser disk player and a set of laser disks. What a time to be alive when I got to watch a “modern and very well funded school system” move from 1970s technology to 1980s technology, in the 21st century.
@Philby Iasgair no they don’t still make them lmao, there’s just a ton of shitty vendors holding small southern American schools in a chokehold only selling refurbished, out of date stuff.
I seem to remember something like this in sex ed in the mid 90s. It was pretty outdated and kept on taking about venereal diseases instead of STDs. :D
LD is also 1970s technology. I can't imagine why a vendor would be selling such an old system less than 10 years ago. DVDs would do the same thing but would cost the vendor less to procure. My best guess is it's something where only one specific video is approved which was only released on one format yet they still care about its copyright.
Damm! The oldest tech I used in school was those old projects that you put a transparent paper and shows on the don’t what is the name.
Also still used 90/2000 laptops that sucked until we got upgrades in 2009 and the government started giving free laptops as part technology program.
Wow, that's just like the Simpsons episode from 1998 where the computer lab is upgraded to Commodore PET styled "Coleco" brand computers, haha. Ah, America and our educational priorities, ha. 😂
I remember these from the early 1990s, 1991 or 1992, when we were still living in the UK. My paternal grandmother was an post office clerk in Castle Bromwich during that time, and she used to take me with her, so I can play with stamps and papers and stuff when my mom was ill. They had that thing there and everybody hated it, especially workers because you listened to it on loop throughout the whole day. And so everybody was very happy when tape snapped off and tangled inside of that damned machine.
This is just like those damn gas pumps that blast commercials at you through their tinny, awful speakers.
I’ve yet to encounter one of those in the U.K.
I suspect it’s only a matter of time.
@@Techmoan Yeak they have started rolling these out at petrol stations in Australia, sadly it's just a matter of time :(
Petrol/gasoline and diesel fuel is going out of style as well, but we will probably get something similarly awful at car chargers.
@@Techmoan I have seen one of those, but I dont remember where... maybe it was in Denmark? Walls are closing in....
I have heard there is a mute button on those. Next time I go I'm going to try to find it.
When I was a kid, the teachers at our Primary School took us to the library and sat us down in front of one of these and played "Little Black Sambo" on it. We all applauded when it finished, kids tended to do that after movies back then.
Matt, great video once again.
Most pots and faders are held together with small metal taps that are bent around the base of the unit. They are mechanically simple pieces and there is not a huge risk in opening them up. If you have persistent problems with a potentiometer or a fader it could either be wear on the resistive track or it could caused by lint or other dirt that can be cleaned off with Isopropanol. I restored several unusable devices by opening up the volume controls and giving them a clean.
I think you might mean isopropyl - propranolol is a beta blocker I'm using in breast cancer treatment as a chemo adjuvant drug..
@@rosiehawtrey Isopropanol and isopropyl alcohol are two names for the very same stuff.
@@mycosys Firstly, I wouldn't call it IPA. It could be confused with the more pleasent tasting IPA (Indian Pale Ale).
Secondly, Isopropanol (Propan-2-ol) is found in most contact cleaners (the stuff Matt is already spraying onto the faders and potis anyway). If contact cleaner haven't killed it, using Isopropanol to wipe it down is probably fine.
Would love to hear more about those mail order Hong Kong films from the 80's you used to buy. I used to get mine from a company called Shaolin Video around that time.
Just here for the Nsync reference…
The post office cartridges are a great bit of history.
Reminds me of Lenny Henry in the late 80s on one of the video ones in an episode of the Lenny Henry show.
Be great to get hold of one of the video ones.
Very interesting, dear Techmoan! But there is still a question looming: Have you received this old can of Coke with the projector, too? 😅
All the best
Valentin
