I picture Richard Wright and Roger Waters in the studio making Dark Side of the Moon! Well done mate! You mind if I bounce a few questions off you when I start me builds? Have you tried guitar on it? Cheers, Casey.

Nice video !! I pulled the rhythm unit from a T500 Hammond organ that my boss had thrown out. At the moment its composite PCBs are lying on my bench. Theres the switching PCB for rhythm selection ( 15 rhythms which, like you mention, you can super impose by pressing more than 1 button), the tempo and rhythm generator board and the drum voicing board which, like you say, uses a white noise source for the snare, cymbals, hats etc and an oscillator for the bass drum, toms, congas etc which are formanted to make the drum sounds. All passives and transistors. I'm feeding around 24 volts into it and it works !! :) Now, I would like to put it all in a nice enclosure and possibly run it from a 12V supply ... I'm thinking I could supply the required 24 volts using 12v and a boost converter. I alos want to be able to trigger each drum sound seperagtely so I can make myt own rhythms. Not sure how to go about that though. Any thoughts ??

I always learn so much from you videos Sam 👍 from another telephone collectors 😊

Great video I loved the history lesson !

Great story!

hey man, i know this will sound stupid, but i want to know how the flip-dot display actually works.. could you do a breakdown of the display itself? the mechanism amazes me and i cant quite understand how the small boxes flip so quickly and cleanly.. all mechanically at that

Thanks for sharing of information.I am a retired telecom field engineer,and my first Phone system was Siemens& Halske direct Phone system similar als this.Later cam the indirect system of Bell (7D,7E & 7EN) than folowed by the SPC sytems such as Ericsson 's AXE, Alcatel Lucents 5ESS,Philips PRX and Bells system 12.But the earlier sytems was memorable for me.

Now consider what may be a bigger insight: the idea that a human can talk to a machine and a machine can reply back. Examples: The dial tone says the machine has done an internal check and is ready to make connections. The dialing sequence that identifies who you are calling. The ringback sound that says the human on the other end is being notified. The busy and fast busy that say please try again later. All things that had once required speaking to Mabel the Operator, now happening by direct human-machine conversation! You couldn't ask a tractor to drive itself to the south forty, yet something quite similar was now an everyday fact in homes and businesses worldwide.

I’ve lived on the boarder of Penfield NY

Here in New Zealand our exchanges worked differently and as a result the numbers were the opposite way around on rotary phones. If you wanted to dial by tapping you had to do the opposite number of pulses to the number you wanted. A 9 was 1 pulse, an 8 was 2 pulses..... a 1 was 9 pulses but a 0 was still 10 pulses.

Great video Mitch. Lovely to see the call out to how this systems were exploited. Not sure whether the phreaking scene was a thing here in the UK - because we never had the long distance thing getting in the way of the consumers of these systems, but it would be cool to see how the strowgers and these systems were massively exploited. It wasn't cost that saw them be replaced. I love telephone Tuesdays and The museum. Keep up the good work.

Thanks Mitch for a cool history lesson! 🙂😎🤓

And If you buy anything today, itll be broken tomorow and you couldnt repair it, theres never done even spareparts on todays electronics. 😢 Vs 1930 or what ever, they all works fine even today, and you could still buy parts to them and repair them fully!

I caused chaos at my school by showing the other kids how to evade the payment mechanism on the payphone on the 6th form by 'flashing the hook'. People went crazy, phoning random people in Australia to ask them the time. The phone bill was astronomical as you can probably imagine. 40 years on it seems childish but it was real funny at the time. Fortunately they never realised who the instigator was else my education would have reached a premature end!

The tones sound different where I live 🌈

yes! i did the 'ol tapping bit on the phones when my mother put the dial lock on it. weird! i was paying for it!

Lovely story! Of course it could only happen in the USA, you upright Brits avoided all such corruption temptation by making telephone operators leave when they got married 😎

Moral of story: Always make career changes based on spite.

A teleprinter? Other Strowger exchanges like the ones at the Weald and Downland. Museum in Sussex and the Internal Fire Museum of Power in Ceredigion?

Mitch your storytelling skills are unrivaled. You could tell me that Mr Strowger was an 1880's cattle rustler that got tired of yelling out for more beans from the warmth of the camp fire and invented telephony so he could ring in his oder, or that he was an 1980s yuppie that got fed up with carrying a heavy brick phone about and and invented the much more reliable landline. Anything and I would believe you. I love telephone Tuesdays.

You need to find a way to link your exchange to the one at the Internal Fire museum in Ceredigion - random calls between both museums would be great fun 😀

instant subscribe Y'all are not only passionate and friendly, but the dedication you put into all of this is wonderful, especially without selling out

Have I missed other "See You Next Tuesday" outros? You rude man! haha

Ha " Wibberly wobberly"! Is what digital, cannot do..💪👍

I started working for a large hospital in 1975. They had a sxs system owned by the local telco. In 1975 they contracted to have an ITT 400G electronic PBX installed. I got sent to the factory to learn how to work on it. In 1984, we had outgrown it and had a Nortel SL-1 N installed which was one of the first digital switches. I attended a number of Nortel factory training sessions to maintain it and eventually it was upgraded to an opt 81C just short of VoIP. When I retired, I ended up teaching CIS classes at the local college and we created a VoIP class. I taught that for a number of years so I can say that I went from mechanical switching to VoIP in 20 years. I love this stuff!

Great video 👍 I had read strowger worked in Kansas but great video and great to see

I remember our town changing from Operator connected to Dial. BOonton 8 to DEerfield 4 when I was in the 1st grade. The Bell system brought (switchboard Style) Dials to class, so we could learn proper dialing and go home and teach our parents. BTW We pronounce it Str OH ger at the CO I worked as a frameman

Undertaking your calls

Looked it up - in Germany, manual operators still worked until the late 1990s for the East German Reichsbahn and in certain military sectors (while civil operators where replaced in 1966). Also the first German mobile net, the A-net introduced in 1955, had manual operators 😱

Video editing looks a bit aggressive, but still manageable.

❤

Fun fact: Our rotary dials starts with zero and ends in nine, so zero is one pulse, and nine is ten pulses. So if you wanted to dial with the hook, you had to add one to the number you wanted to dial. :)

Man was so pissed about his business being stolen he made the culprit’s entire field of work obsolete

I loved told call boxes in the UK of the '80s, I could make free calls from them and it saved me quite a bit of my pocket money as a kid.

The first thought I had was put different effects on different phone lines (e.g. hosepipe delay, spring reverb, vocoder, etc), so you can literally dial-up an effect to be added to your voice when you speak/sing through the receiver.

Sam's car! Hook up Sam's theremin car to the exchange!

I jumped over to my favorite vintage version of this content to share this link and what did I see, but @LookMum in the comments there. That was nice! ua-cam.com/video/7R9bHJfymjg/v-deo.htmlsi=rFk_oNs6aVSurd74&t=854

This was on an episode of the Lateral podcast with Tom Scott too! :)

Abingdon exchange was the last exchange in England to go automatic in 1975, which is where i worked on installation and testing. i even got a first day cover celebrating the fact ;)

I think getting with some amateur radio guys and setting up a phone patch would be a great addition. Bonus if anyone has any ancient bag-style mobile phones that have been reprogrammed to make the calls.

Interesting Strowger story :)

1:50 Hook up an RPI and create an old style Internet with it. I think that there is already software for it but im not sure. I think i saw this idee on YT.

The call I've been waiting for! Amazing stuff

The company's website seems to be down and they aren't responding to my emails 😢

ದೂರವಾಣಿ ವಿನಿಮಯ ಕೇಂದ್ರ.

Love it! It looks so fun! I am, however, going to be that guy… I saw one fire extinguisher in the walk through. With as much electronics and motors as there is in there I’d be very worried about fire. Is there a suppression system built into the museum? I absolutely love the semi-controlled chaos and jumbled nature of the place. Would be magical for a kid to explore. Alas, it doesn’t look as though I would be able to get in there with my walker very well. When you expand please keep wheelchairs and other mobility issues in mind. I am very happy this exists as it is, would be even better with more space.

How would the off hook tone sound like? May you please do a video on the off hook tone? Thank you.

If you pick up the phone and don't dial out and leave it off the hook for a long time, does these type of switches sound an alarm through the Telephone receiver?

Welcome to your interface with the general public - they could break a ball bearing….😂

Great informative video of a bygone era. You could probably do all that with an Arduino Pro Mini these days but it's fantastic to see the electro-mechanical solutions of the day. :)
