Talking Pictures: 3M Sound on Slide multimedia system from 1969

[@Elektronijaenis]

I was going to come give the same translation here. :D About the uses of this kind of technology: As a kid, I remember a school trip to a candy factory (Fazer). First thing when we got there was guide us to an auditorium where we were shown a big corporate slide show about the company. That slideshow was done on a bunch of projectors. I remember the images to fade to other images and the images on the screen changed maybe in 6 separate parts. I believe the image fades were made by fading the light on one projector out and another in at the same time... So it was probably at least twelve separate slide projectors there sychronized to one giant slide show. The soundtrack was continous, so the show probably wasn't using this kind of projectors though. (That was maybe late 80's.) Much later at work one of our offices had an auditorium that had a bunch of slide projectors installed. That was early 2000's and by that time they were not used anymore (They were practically only collecting dust at that time.) I wish I had examined those a then. The bureau I work for moved out of that building years ago. So... While I have no experience about that particular slide projector, maybe these experiences will shed some light to how that kind of projectors might have been used back in the day. And maybe "slide projector multimedia" was more common in Finland than elsewhere.

Remember when you were young and you'd go with your parents to their friend's house who had just been on holiday and they'd have their slide projector out and you knew it was going to be boring and you'd be there for ages. Thankfully with the invention of the internet, people can post their photos on social media and we can just ignore them.

[@ZGryphon]

When I was a tiny child, before VHS, my parents shot some 8mm home movies of me learning to walk and such. The usual nonsense parents of small children think is interesting, you know how it goes. When the film came back from being processed, my father borrowed a projector from work, my grandparents came over, and they and my parents sat down and had a lovely time watching... the highlights of someone's African safari. Boy, I bet those people were disappointed.

That part reminded me of my grandpa. When I was a kid, my parents, sister and I moved to a town in the mountains and we went through some tough times financially. My grandparents used to send us boxes full of stuff like food, items for school and such, to help out. My grandpa did the packaging; he put paper as packing material, inside a wooden box, wrapped with steel wire to keep it from opening or coming apart. Took us a while to open it, but you can bet nothing ever got damaged in transit!

Arent wood crates likely to shatter if thrown on the ground My rule for packaging is that the package has to survive a 6 foot fall onto concrete Seen the videos of usps/ups (insert your local shipping company here) throwing packages over fences they get paid by weight shipped so speed is very important to them

These things remind me of when I was a kid, we would watch filmstrips in school, and they came with cassettes that had the narration on them. There'd be a beep to tell the teacher, or more often a student who'd been assigned to do it, to advance the film to the next frame. It was a coveted assignment, and I was very good at it. I can still remember my Luddite-like fury and heartbreak when an automated filmstrip projector that could hear the beep and advance automatically came along and put me out of a job. This device is like that, except mechanically baroque enough that I would have forgiven it. :)

Fantastic! I was not aware that anything like this existed. In 1989, for Hewlett-Packard's 50th Anniversary (in Australia), we were still using slide sets with recorded soundtrack, although there were multiple projectors and they were cued to the soundtrack. Somewhere in the garage I still have videotapes of those presentations... This is a brilliant attempt at replicating that function around twenty years earlier, when most of use were using a standard slide projector and providing live audio commentary to the suffering audience.

[@SierraLimaOscar]

Ahh, the magic of Multivision! I produced a few of those for tourist destinations in Yugoslavia. The Kodak Carousel slide projectors cost an arm and a leg and there were thousands scattered around corporate boardrooms and museums. I remember the first show I did (4 projectors! 😂)the recording would only move the slide forward and dim the bulb to do a cross dissolve with the other projector. So if the carousel skipped a slide the whole show was out of wack. Later on we used a digital system from an Austrian company (Stumpfl) that kept track of the positions of the slides. Good times.

WOW! This brings back memories! I worked for Pacific Gas & Electric (PG&E) in San Francisco from 1984-1989 and they used this system to train power plant workers on “Lock Out, Tag Out”, Power Generation Steam and Water Cycle, Electrical Distribution systems, etc. The squeal noise is the automatic focus compensation. YOU set the focus for the first slide and the machine tries to maintain that fir the other ones. As each slide is projected, heat from the lamp causes the slide to expand and flex. The machine has a detector that sees the slide flex and triggers a re-focus of the slide. That’s why you hear the focus motor squeal and the slide refocuses a few seconds after it’s been displayed. It’s quite a neat feature! Great video!

[@DavePurz]

Our projector had a terrible “Wow” problem. They’d play the sound of a transformer humming and the 60 cycles varied +/- 5! With the sick transformer sound in the background they’d say, “Recognize that sound?… That’s the sound of power!” Ha Ha Ha! The training courses were professionally produced. I believe by Edison electric in Chicago Illinois.

[@yerbigbeanoyeah]

I enjoy your channel and this segment was the best ever. I had no idea that these things even existed. From 1987 to 1997 I worked with an excellent photographer who did multi-media presentations of his work for civic groups and women's clubs. He has passed away but I have fond memories of our work together. He used two projectors with a sound system I designed using Crown Audio amplifiers in a small rack with a Crown preamp and a Tascam four track reel to reel in a custom flight case. The speaker system was two Boston Acoustics speakers and a powered subwoofer. The sound tracks were stereo with a blank channel and and a tone channel for the projector cues. We ended up doing three major fifty minute shows and several shorter shows which he presented dozens of times. I started with razor editing and later progressed to mixer based sound editing. Aside from the hours and hours spent listening to Yanni music it was a great experience. Seeing the other technology which was available at the time I can see why he sought a higher quality way to go. Keep up the good work!

However, it didn't save the sound on the slide holders like this one but it was connected to a separate reel to reel player instead. I believe there were some educational slide sets with pre-recorded tapes that were shown to us. The setup looked very archaic already back then and it wasn't used much. Also, the fan noise drowned pretty much the sound on the tape.

[@telocho]

When the film heats up when projected, it plops in its frame since it becomes larger due to the heat. The autofocus senses that and re-focuses and causing the squeel. Auofocus works by a small incandescent bulb (like a bicycle lamp) under the slide where the lens is, reflecting to an eletronic eye, and placed so that it is not sensible to the light from the projector bulb. Professional slide frames have a glass substrate to avoid this refocussing for a more professional presentation.

[@randyariddle]

Wow - what a fantastically complicated way to solve a problem nobody had.

[@benholroyd5221]

This is pre VHS though. This isn't solving the problem of adding sound to slides. This is solving the problem of displaying synced picture and audio. The existence of KZbin would tend to suggest this is something people find useful. As would a few multi billion dollar industries. Watching La Jetee on this would be interesting.

@@plan7a The problem is wood spreads tree diseases and pests. That box would be rejected for real international travel (i.e. outside the EEA) because it doesn't have a certificate stamp for fumigation or heat treatment.

@@straightpipediesel very true. A few years ago someone shipped a big wooden crate from Norway to me (I'm in France). It was a vintage tape recorder. In addition to being quite expensive as you may expect, the sender had to build the crate from approved pallets and planks. Norway and France are both in the EEA as far as I can tell, but maybe the box had to travel via non-EEA countries, I don't know.

[@mrnmrn1]

@@straightpipediesel Exactly. Our company had to switch from wooden boxes to MDF boxes about 3-4 years ago because (I think Switzerland) do not accept real wood boxes anymore. MDF is still mostly wood, but it's processed and treated, and therefore guaranteed to be free of deceases and pests.

Love the fact that this thing may have remained unused for decades and its first use means one of those magnetic discs now has a recording of “someone wearing a bin bag”. Absolutely hilarious!

That squeaky sound seems like auto-focus. We had similar projector (without sound) and it used several bulbs and sensors to identify position of film and adjust focus automatically. Slide holders are not perfectly matched and it is possible to insert them in opposite direction. This is causing small variation in film placement (in light path) and causing picture to go out of focus. Automatic system can identify this small variation and adapt focus if necessary ... that sound seems like motor is slipping when trying to move focus on lens. Another possibility is that one of sensor is obscured by dust and / or detection bulb is not working and it is trying to move focus in one direction hitting limits of lens .... btw. it was really paint to present with projector without auto-focus. It was either all pictures a bit blurred or operator was adjusting focus on each slide ...

My mother had a standard mechanical slide projector that looked like this thing, just a bit smaller. It also had problems with slides being stuck in the external position all the time, even when it wasn't cold. Later I had one of those rotational magazine projectors that very regularly suffered stuck slides as well. So it's actually a quite common problem amongst slide projectors.

My dad had a 3M projector exactly like that except no sound. I remember as a teenager seeing his Vietnam war photos on slides. He’s since transferred them all to digital. But man, seeing that projector I can really remember the clackety clack of the advance mechanism and the heavy solid feel of the metal case.

[@davechupp7922]

Matt, When my father was alive, occasionally he would break out the old slide projector, a Kodak Carousel, and screen, show us old pictures that included my brother and I doing our fun and silly things when we were small. I'm sure he had many hundreds, if not thousands of slides, in many carousels, of vacations, work related and family photos that included an occasional story to narrate the slide, stories we likely heard many times, but never boring. I think my dad would have had a lot of fun with your machine.

I was thinking the same but then started to wonder: is it able to reset itself back to the beginning of the slide set without operator intervention?

[@SimonPain]

True. Maybe not then. I wonder if they did a carousel for it?

[@YodaPagoda]

My grandparents were very well-traveled people, and naturally I aspired to travel around the world like they did. In 2007, I began working in the Middle East, and was able to travel to Europe, Japan, and to The Philippines...all places they had visited and produced caddy upon caddy of slides. Of course I had taken pictures with my digital camera, but I was able to create slideshows that could easily be presented on almost any television from my iPod. My grandparents were astonished at not only my adventures, but how technology had progressed.

Back in the days before PowerPoint, it was possible to get 35mm slides produced from digital media by a "service bureau". I did this in 1995 to create slides from PostScript files to present at a conference. I would not be surprised if a camera shop in your area could still do this - you don't need to shoot a roll of slide film just for this. Instead, you could have had printed anything you took from a regular digital camera.

[@Josh_D78]

My dad loved those because he always got the free stuff while everyone else had to sit through hours and hours of presentations. The trick is that when they take you into the closed room to discuss the timeshare you just need to be brutally honest and tell them you're just there for the free trip to Las Vegas and the free show or horse back ride (or whatever else was offered as the hook) and that you don't want to waste any more of their time because you have zero interest in buying a timeshare. The trick is that by the time your done with the presentation it is usually too late to take advantage of the free thing they were offering so they rarely had to buy tickets or pay for free entertainment they had promised.

[@gwesco]

Once upon a time, the hospital I worked for had a Carousel system that synced multiple slide projectors with a cassette and provided a seamless presentation that was almost as good as a film. I was in Boston MA around 1979 and they had the same system at Fanuell hall celebrating 250 years of Boston and I think it must have had over 50 slide projectors synced to sound. It was a really moving presentation and again, almost as good as a video would have been. One of the audio comments in that presentation was two proper Bostonian matrons discussing why they were there and one said, "I came to get scrod." (A type of fish) The other lady said, "I didn't know there was a past tense." Floored me as I had always heard Boston was very prim and proper! :-)

But Matty you are still a superstar for donating this device and your outer packaging, It's great to see such items. Great work guys.

[@McAster99]

My father used to use one of these at a computer chip manufacturing company for security purposes. They would enter a room with one of these, have the slide show a photo/photos of an upcoming project they didn't want getting out, and a person could leave comments and notes without being able to take anything out of the room or leave anything where it could be stolen. A bit much for the 1980s to be sure considering what else they could have done, but it served a purpose and worked for them. Years later they switched to a much better system and my family got it since it was outdated info at that point. I just remember listening to all sorts of engineering and coding talk, and the occasional office gossip with a "make sure to record over this" that I guess didn't get done.

Interesting video works pretty well considering it's age and the sound quality was a lot better than I was expecting I can imagine this in it's day being a great piece of kit especially when doing presentations you won't have to keep repeating your self time and time again telling the audience what each slide was you would only have to do it once. I have some slides I scanned them so I can see them on the computer as I no longer have a projector. Thanks for sharing.

I bought a slide storage container, like a mini suitcase, to store all my slides in. Turns out it was full of slides. I ran them through my projector, and about a third of of some dude's house, with visitors, etc. a third are of the outside, with a large garden live steam railroad (quite amazing, in fact), and the last third are photos of the dude's TV, showing shots of the various Apollo missions! He's got several missions, including Apollo 11, IIRC. They aren't all the greatest, esp. since sometimes he got mostly the "scan lines" between frames, and the photo isn't all screen. But still, this guy took the effort to make "screen caps" of various Apollo missions as they happened. My original plan was to toss all the slides, but I kept the railroad and Apollo slides. Very cool stuff. I can see why people would buy these things. You never know what you'll find! My plan is to buy an adapter for my camera, to "scan" in all my slides, including these ones. but that's been my plan for the past 15 years! Still haven't done it. I may have some free time next year. Maybe then ;-)

My Dad who was in life insurance had a similar piece of equipment that did pre-done shows. It was built around a Kodak Carousel Slide Projector and a cassette player. The slides were done by a graphics house (this was before Powerpoint) and loaded into a tray. A tape was prepared with the appropriate narration and a pulse tone to advance the projector. Through a system of lenses and mirrors was projected on a screen from inside. It was used on a tabletop for small groups. It was branded as a Roadshow, but I can't seem to find anything about it. Sadly, in my youth I took the thing apart to get the slide projector and trashed the rest of it.

[@johnathin0061892]

Surprisingly, there are people on eBay and such who will actually pay for other peoples' old slides and family home movies on film (and sometimes photographs), especially if they features cars or fashion of the day. Some collections can fetch good money.
