That was absolutely awesome. I'm so glad the world has such great collectors and restorers like yourself and John from the Telephony museum and not just junk hoarders like myself.
Love the wall of green phones! And the old wind-up wall-mounted phones have a place in my heart from seeing them on shows like Lassie when I was growing up
Fantastic museum. I love the sound of Strowger exchanges. My grandfather ran an exchange in a small town in the UK until the mid-80s so I remember going to see him and hear the racket they used to make. It's very easy to visualise how the system works!
Thank you for shearing your tour. I was at the old museum just a few days before the fire and met, among others, the photographer that shot the pictures you were looking at on the wall, and shot quite a few myself. I have not had the opportunity to visit the new museum as yet. I also manage the websites for Telephone Collectors International and Phil's website showcasing his personal collection and switch.
My dad has worked with telephones for over thirty years, boy would he love to see that! Great collection and also great video thank you for the time you put in making these videos!
A Truly impressive achievement to rise like a phoenix from the ashes in such a short space of time!! It is a testament to the spirit & tenacity of all concerned ! Long may it continue to be so
I remember the Post-office in town having a whole floor full with switching units for telephony when I was a kid. But I think those were done with relais already. Quite an impressive museum, especially for a 3-year rebound from a fire. Fantastic.
On that ring generator, you can still buy the switches as brand new current parts, used for railway signalling systems. I still occasionally use a 1939 Ericsson phone, originally meant for local battery use, but which is happy after some jumpers to accept line power instead, and it works well, just that of course it has no way to generate DTMF or LD to dial, as it has instead the hand crank generator. But does ring quite well, and interfaces nicely with modern POTS lines. Also have some older phones, from the 1980's and 1970's, though they are not in as good a condition. Wonder if they have any of them around in the collection.
Thank you for taking us along on your trip to the JKL Museum of Telephony. It's fascinating to see the progress of something so ubiquitous in our lives. It always amazes me that the Strowger step-by-step exchanges were so bullet-proof. Yes they required constant maintenance, but at least if something went wrong a switch could be swapped out, stripped down and repaired. Try doing that with a solid state switch. Replace and discard, that's the current method :-( Those Strowger switches were an important component in early computers like the Harwell Dekatron computer from 1951. Mind you, the Harwell computer weighed 2.5 metric tons, so I guess going to solid state does have some advantages! :-)
Notice at 5:50, the candlestick, front, right, is equipped w/ a "Hush-a-Phone." The was an early privacy device, but was famous for violating Ma Bell's "no-foreign-equipment" rule. That is, if it didn't come from Western Electric, it couldn't be connected to the network, acoustically (which is how it connected) or otherwise. Led to a lawsuit years before the Carterphone.
Yup I saw that in there. I wonder if there are still some active phone lines in the nation with a phone rental/equipment line item. It was spelled Carterfone for anybody wishing to research it.
We had a neighborhood switching office two blocks from my house. And since my uncle worked for Ma Bell we got a tour. No idea what vintage the stuff in this video is, but the switching office I visited was more like the one in Three Days of the Condor.
That is simply *AMAZING!!!* I would love to be invited to that place sometime. It is very tragic what happened in 2015. I really like how many of the phones are hooked up and operational, and the switchboard in operation, unlike lots of museums that just have stuff on display, never ever operated.
Exactly, what's the point if you can't play with it! When I go to the Vintage Computer Festival Midwest, they use a switch for Phones and Computers. So you bring your collections of both and get to use them as they were intended.
I remember the sad day when it was announced that the JKL museum had burnt, they have done a great job rebuilding the museum. Nice to hear the sounds of the Step By Step switch working, along with the old Step by Step dial and ringing tone, one does not hear that nowadays with the Nortel DMS-100 and Western electric 5ESS switches. The Picture Phone is an interesting failed product from Western Electric/Bell Telephone. Thee engineers overcame many technical challenges to make the system work, things like making a camera tube that would not suffer image burn in, since it was always on and normally looking at the same background, or how to make a system that was (somewhat) practical to integrate into the standard telephone system. There is another very impressive telecom museum in Seattle, which is open to the public and is in an old switching office, one of their current projects is getting a very rare Western Electric 3ESS switch.
CuriousMarc I particularly like your IBM restoration vids. Have you seen the George Lucas student film THX 1138 4EB? (The short film that predates the theater film “THX 1138”.) The 1967 short had a lot of IBM hardware as set design. And the Navy Student Workshop is credited in the film. So I assume the computers are Navy hardware. It’s a very interesting 15 min short. Thought I’d share. th-cam.com/video/GB3fbtUYgRE/w-d-xo.html
Ouch about the fire, my regards. Looks like they've managed to get a pretty impressive collection going again. Including that electro switching room and with all the phones being hooked up.
So many Telephone Exchanges in the UK still have test desks sitting unused in them. When I started in telecoms 31 years ago, strowger was still in use in some exchanges and one of my first jobs was upgrading all the cabling inside Pan Am’s Heathrow operation so they could remove the huge room PABX 4 strowger exchange and replace it with a Nortel boring box on the wall. Happy Days !!
If you ever visit the UK, go to the Porthcurno Telegraph Museum, right at the sea where the actual first UK telegraph lines whent into the sea to control the commonwealth... Great experience, lovely, dedicated people and a stunning location... Great video btw ;)
I live near Alexander Graham Bell's homestead, which they turned into a museum. I went there once as a kid, but I was too young to appreciate it. I'd love to go back some time.
Shame about the initial loss. Already a stunning display, and I love how they have the phones all wired up and working too. How does one get an invitation? They mention just calling.
calling is the best way to reach them. It's a small museum, so that's why they have appointments set up through calling because they can only handle so many people at a time.
When CenturyLink purchased Qwest, CenturyLink management liquidated (disposed of) the telephone history museum pieces at 250 Bell Plaza in Salt Lake City, Utah. The disposal coincides with the rebuilding of this museum and I recognize some of the same objects that I used to see every day in this JKL Museum. I can only hope that after CenturyLink was done, a place such as this JKL Museum picked up the items for their own display because CTL was just going to throw them in the dumpster. I really never found out where that old collection ended up, but I would like to think some of it landed at JKL.
I don't live too far from the Alexander Graham Bell homestead, which has been turned into a museum. I've been mearning to go there for quite some time. I went once with my mom when I was a child, but I was too young to appreciate it. So I'd really like to have another go at it.
Great museum. I spent some time in exchanges and they were always filled with equipment that was no longer in use. Too expensive to move it out so all they did was just switch it off when it was replaced by newer equipment. So pretty much the exchanges become museums themselves.
(I love John, the owners slip of the tongue "to pervert history and have fun" Another great TH-cam synchronicity.... I've recently acquired an old (British) 746 telephone (a green one!!!) and have been working on getting it working and then... along comes this video. Must be a morphic field resonance or something. ;)
I did some searching in norwegian sources, and it seems the norwegian telephone also sent the reverse signals of what was expected (which was a headache when connecting the entire country). If I'm reading it correctly, we actually know where the phone is from - Bergen.
when i heard the dial tone on the speakerphone i thought "ok ok cool" but when i then heard the small doot of dial tone after the first digit my mind went straight to "no waaaay" territory
Complete with operational instructions in the center of the dial. Given the shield on the front, this must have come out of some government office or something.
Museum of telephony but can’t see any British or polish examples? I have a couple my dad collected from the GPO, new old stock but batch sampled. Fish are welcome to have!
Switching room was cool, I've seen similar I think in a bell laboratories video, I forget the name of it, switching step? Hook and lever, really escapes me
So, if I wanted to aquire a '95-'07 (southern) bell systems pay phone, would your museum contact be able to assist with that? Edit: looks like there was some name flopping in that time. I remember both southern bell and bell south, and both seem to be actual baby bells.
one day we're gonna run outta all the exotics required to make fiberoptics and super hightech electronics, and have to go back to this stuff, and it's thanks to guys like these we'll still have working examples of what we'll have to go back to.

that fire truly broke my heart.
Do absolutely go to the Museum of Communications in Seattle, more of a switching focus, but plenty of newer picturephones.
The Seattle museum is unbelievable. Well worth the visit.
Astounding to what level everything is functioning. I can't blame the curator for wanting to protect the collection but what city is it in?
I wonder if this museum hosts a network that uses the 2600 hz tone? If so, the blue box would work on it. That would be really cool!
8:12 Was the piano music in the museum, or did you add it yourself in the misguided belief that we *need* lots of sound to survive?
I would donate my time to repair items for this wonderous playground!

Check eBay. A good portion of the museum, and almost my personal collection, came from eBay.
I miss my red slimline touch tone phone (1974) I had in my bed room. That was pretty high tech for the day.
"It's a magical system". Indeed!
Nice museum. I don't live close enough to see it at least once. 😢
Elegant telecommunications for a more civilized age
Mai visto niente di più bello!!
LOL, I did not know they had speakerphones that long ago!
Ha, "Do not touch"! You know what the first thing I do is when I see that kind of sign?
So the Norwegians numbered their phone dials the same way we did here in New Zealand. Interesting!
Only in Oslo, the rest of Norway had the dials the normal way.
Fricken awesome!!!!!
