We made a sample pack of lots of telephone exchange noises for you to use in your avant-garde ambient masterpieces.

"Very enthusiastic about starting projects but not really thinking about the implications of finishing them".... Ooooh! That struck a chord here, I'm telling you!
What a bunch of cool stuff. This channel is so awesome. Every time I watch it, it takes me back to my phone phreaking days. Oh! You should do a video on that stuff! Show how some of the old payphone hacks used to work. That would be awesome. That bar machine is bonkers. I hope you can get it working. I had no idea anything like that existed. Was that machine custom made for that task or did they just use an existing calculator or something and modify it to do the drink orders?
I love watching these telephone exchange videos. Even though this equipment is from a bygone era, I’m still deeply interested in it. I wish I could have been alive during the 2600 era to get to tip-toe around the network.
The pub customer dialling 111 at 2:16 is rather funny for me as a New Zealander, because 111 is the emergency number here. They must have been really desperate for a drink!
5:25 Looks like a Creed 7B teleprinter? I had one in my bedroom 50 years ago, hooked up via a 50 valve gizmo to receive text from my shortwave radio. News wire services were common then, and embassy communications all over the world!
EPG1A (the big one) was for international call timing at the Group Switching Centres. EPG2A was for local call timing and were at pretty much every exchange.
I'm currently reading the History of the U.S. Signal Corps, vol. 3. The Signal Corps was attached to the U.S. Army, and during WW II was responsible for designing radio teletype relay systems, which were then given to commercial companies for manufacturing. Some of these systems were also used in England. The relay systems had a teletype machine at one end, which could be connected to a telephone line that ran to a radio transmitter, with a receiver some distance away. In between could be any combination of more phone lines and radio links, until reaching the second teletype at the other end (up to hundreds or thousands of miles away). There's no mention of modems in the book, but that or a similar circuit would have acted as the interconnect between the teletype and the other stuff, and was pulse modulated. (They even had FAX machines back then.)
I used a teletype to communicate with the old Digital (?) mainframe in my freshman year of high school in 1976. Big reel to reel memory and parity lights on the front, just like in all the old movies. It was leftover stuff from some business in Detroit, where I am from.
I love that order machine for the restaurant just excellent 👍
Baudot from teletype to a linux TTY terminal should be quite possible to do but requires a voltage downshifter. I think curiousmarc did show one example how it can be done and his schematics should be available.
The headlamp is hysterical…
Amazing to think all that started off with a passing curiosity about a single strowger only a couple of years ago.
teletubbytype? make it happen Sam :)
Have you talked at all with any of the folks at the Connections Museum in Seattle? (they also have a YT channel) wonder if they could provide any ideas/pointers on that funky teletype
one of these days I need to make one of those converters so I can wire my teleprinters over an asterisk server. Preferably the one |I already have but yeah, Mate I have converted one of those teleprinters to work as a tty terminal but I don't want to modify the unit but just connect it to an adapter.
Great work guys, no disrespect meant, but you'll still be working on this stuff or similar, when you in your 90's as it's a never ending job! Thanks for sharing! 🙂😎🤓❤
Absolutely loving this shit, gentlemen.
It could printout....football scores. 🙂
Speech to teletype? Why you no speech to Teletubby?
It is always good to have random stuff in the shed.
Raymond Baxter - what a legend!
cool headlamp
its the 50v dc headlamp that was part of the toolkit.
Nice, See you next Tuesday ;)
Shouldn’t be a big issue getting the teletypes to run at 45.45 baud as lots of hams used to do that. Would be cool to see teletypes and minicoms talking. How about adding a PC with Ham RTTY software as well? That’s also 45.45 baud
My first programming was using a teletype from home with a 110baud acoustic coupler modem. It replaced a ton of time making punch cards and running them through a card reader a 30 minute drive from home.
I feel like one of the really cool things you should try (if they're up for it) is set up a teletype connection with the Connection Museum in Seattle.
2:28 Pint size computer? Pints must have been really big back then.
Cool stuff! Thanks for sharing!
2:42 was I tripping?
Or did I see Motorola, in a dial?
clock tease? anyway like the head lamp. cheers
time stamp : 7:03 or you could set up like a text/email through the telephone exchange?
Ah, T.I.s and the great Rate Book
Used these in the USAF and a civilian weather station in the 70’s. Five hole paper tape, type up the message or weather report, check for accuracy, then put it in the reader and let it run, (or rip, bummer!)
TOP SECRETS Yepp! . ok no joke when is the International MOVIE???
