Lg compact telephone thingy
Aaaah, speaking as someone who is born deaf, that takes me back. The minicom (which was given to me free by the health services) was revolutionary in terms of using the phone to keep in touch with other people in pre-internet times. I recall it used the TTY signal for sending data from one minicom to another and the "telephony" software on Windows 98 and a 56k modem just happened to be compatible with minicoms. It was handy but it wasn't that long before SMS texting took over as the standard means of keeping in touch with my deaf chums.
What I do remember with using a minicom was that it was considered "good manners" to type SKSKSK to properly close the conversation, in fact I know a couple of deaf friends who still do that in Facebook messaging out of habit!
What does sksk stand for??
@@joe-e-geo The Morse code pro-sign SK (S and K without the pause) is the code for "end of transmission", considered an abbreviation for "Silent Key". I'd assume that's where the Baudot use came from.
(Not coincidentally, "Silent Key" is radio ham slang for someone whose telegraph key had gone permanently silent, i.e., someone who's passed away.)
@@unsoundmethodology I learned this as Stop Keying, but I always thought of this as 'Popeye the Sailor Man' or . . . _ . _
Telephone Devices for the Deaf (TDD) were everywhere at my university RIT in Rochester NY where ~1 in 10 students are deaf. The deaf user could watch the signal light to see the ringing sound, which then changes to a flicker when someone speaks. They would tap the space bar once or twice to announce they are using the TDD and the hearing person should connect to the TDD.
In addition to the convention that you type 'SKSK' at the end of a conversation, you let someone know it is their turn to type by typing 'GA' at the end of your sentence for 'Go Ahead'. This only works if one person types at a time.
That's the one with the GA! I've been trying to remember the other "keyword" with using a minicom, it was like our own version of saying "over".
The light bulb that was missing is used to indicate when the telephone line is ringing.
He'll definitely need to get that bulb then! I KNEW there was some simple explanation I was missing : )
My late sister was profoundly deaf. I remember using these to talk to her when I was at music college in the late 90s in London.
Mum and dad had a teletype 5000 at home, and my sister made sure everyone had one. But I was in halls at GSMD so didn’t have one at first,
In my first year of college, before I had my own place (and before I purchased a Nokia communicator with all my pennies to call my sister on text that way) I used to have to walk down to Liverpool St Station in London to use the two pay phones that had one attached. They were really unreliable and hidden inside a stainless steel case with terrible keyboard. Man they sucked!
You used to type your message and then “GA” to let the other person know it was their turn. To sign off both parties typed “sksk” after their final message to let each other know it was time to hang up.
The teletype service is still operational afaik and many hard of hearing people still use them (although most people now just use text messaging).
If you were really posh you had one with a text answering machine that would answer the phone for you and take a message!
Love what you’re doing here. So glad I’m a Patreon :)
TTY is still a thing in the States but has been largely replaced by SMS/text messaging. 911 call centers still regularly do TTY drills.
Would GA = go ahead??
What the heck would sksk stand for?
@@joe-e-geo If I remember right, it was an old morse code shorthand basically saying "end of contact."
@@joe-e-geo GA does mean “Go Ahead” and SKSK means “Stop Keying”
And the important message rang out across the desk.... "I'd love a pint."
Always cool, that stuff you do...
I'm old enough (nearly 50) to have spent some time in old Strowger BT exchanges, mostly at Hatch End and Pinner. The noise, the smell, it was glorious, my step-dad Graham took me around and showed me everything and explained how it worked. Also how "taps" worked and were applied, and if they discovered one they were told to just ignore it :) When Hatch End went digital the entire floor of switches was replaced with one smallish box on the side of the room and it was silent.
I remember these gadgets well. My parents are both deaf and imported a small number of them in the early 80's from the USA to the Netherlands where we live. Those two keys on either side of the space bar that are marked "GA" and "SK" actually produce those two-letter combinations. GA stands for "Go Ahead", to indicate that the other side can now start typing, and SK stands for "Stop Keying", meaning that the conversation is over. The equivalents of respectively "over" and "out". Enjoyed hearing those bleeps again after 30+ years!
“Going down these rabbit holes” - this is what makes your channel unique - as it leads to more fabulousness - so please don’t stop 👍🏻👏🏻❤️
This is honestly one of only two or three channels that I have seriously considered becoming a patreon of. So much unexpected, fascinating content.
I love reading the comments off all the deaf folks & family members. I know those used to this think nothing of it but I am still moved deeply in my heart to read the stories. The incredible talent of LMNC is like a Universal language of discovery and its wonderful this channel is building community for all. Its A rare & healthy achievement that brings hope and works against the current fear & propaganda.
So nice that it even supports the backspace over the line
Cool, we used to use minicoms in a London Social Services dept back in the mid 90s to talk to customers. I loved them.
I love the sound of them so much, it's what I think of when I think of telecommunications
Used to support these in a job a bunch of years back. There was an optional printer you could add to the slot that lifts between the I/O that would print off the transcript. Pretty cool!
The rabbit hole goes even deeper, the frequently shift keying was also used by the kansas city standard. It was a standard for loading software from cassette tapes. The BBC micro and the MSX used it, at a baudrate of 1500 baud. If you play a computer cassette it sounds like a dial up modem.
cool, I have one of these...the lightbulb thing is a flash so a deaf person can see that the phone is ringing....it would be cool if you had a number we could call in and talk with out TTYs
Reminds me of the Texas Instruments Silent 700 terminal. They used acousticly coupled 300 baud modems and had a built in printer.
Back in 1984 i used one to program the Siemens SD192-MX PBX.
Although the acoustic coupler on top makes these things look like an 80s artifact, the fact that the Peterborough code is given as 01733 and not 0733 shows that it must date from 1995 or later.
There used to be text relay services which enabled users to type and read conversations with a human operator translating in either direction.
If you received a call from a user, it could be a bit disconcerting because you had to realise that you weren't really conversing with the operator but with the person typing and reading messages at the other end.
This was 1996 but these were one of the last of these items they had been rebranded but stayed largely the same since early 890’s
Very fascinating rabbit hole, my good sir
'Im typing with my whistle'
Captain crunch would be proud of you.
They had one of these in the airport in Flint, MI and whenever my mom and I would go up there to see family I'd play with it while we waited for baggage claim. Never knew what it was for, but I figured it was for business people to send computer data over the phone. It was at a self serve kiosk for I think either a rental car place or a hotel chain. I spent a lot of time doing what you were doing at 4:18.
Stuff similar to that is still used for things like maritime weather reports, and random chats by HAM radio hobbyists. If finding those channels on the radio, it's pretty much the same FSK tones too. Some of the WebSDR sites you can find online (easiest example to play a bit with without having to get some kit yourself) will have a panel that can help decode it, provided the right settings are used.
This is so retro-futuristic.. I LOVE IT!!!!
That was a better demonstration than when they were not obsolete. If you can find someone with a saxophone, perhaps you could do a re-do of Secret Life of Machines.
Oh man, Acoustic modems was the main way to go back in the 70's and into the 80's. Yes my first modem was acoustic so that tells my age a bit :-)
"Greetings professor Falken, you are a hard man to find." - out the window the auto-coupler goes. We used to have rolls of that punched (ticker) tape for college projects but it seemed more useful as party bunting.
Takes me back to the early 1980s, I was using a Creed 7 teleprinter on ham Radio. I also had a deaf friend who had one of these acoustically coupled type machines, and I was able to use my Teleprinter and audio decoder to chat to him over the phone. I also did a lot of work in the RAF using teleprinters. It's nice to see the old kit again.
Wow, backspace works too. That's great.
That's cool how it backspaces on the other machine too.
Thanks for this. Made my day. Never seen this before. This is one of the best RUclips Channels out there.
Woah now that takes me back a bit...one spent many a year making phone calls for one's deaf relatives using one of these. One still has the mobile nokia communicator version too.
That’s so wonderful! Thanks for that! Brighten up my Monday.
Absolutely brilliant, you are a living legend.
Thank you so much .... You have brought back a long long ago memory. As I saw your video i noticed the Electronic Lab kit you have in the background. I had a similar Kit. So i googled a bit and i found exactly the Kit i had as a child including the Manual. While poking around in the manual i felt like this 9-11 year old boy i was when experimenting with electronics .... Thanks !
Dam, this is amazing! You see that stamp, Ultratec? They're the parent company that produces the Captel phone, produced here in Madison wi. My partner works their tech support line 👍
I love this! I’ve worked in IT and I’ve only found the origin of Baud rate from this. Have a play with putting your lyrics through this and have the sounds this produces as a rhythm track. What’s the worst that could happen?! 😃
I like the idea of being able to call up Kozmo and chat
I used an acoustic coupler for a short time. The circuit inside was remarkably simple, just a few transistors. The tx part was basically a vco connected to a comparator which had txd as input. Therefore ones resulted in a different frequency being generated than zeros. The baud rate was entirely determined by the equipment connected to the coupler. In practice that was either 110 or 300 baud.
I also had a teletype for a bit. British Creed model. The serial to parallel conversation done by bits of metal was amazing.
I do all kinds of digital stuff with ham radio. You can use a PC sound card as a modem and hook it to a radio use the AX.25 protocol and bang internet over a analog radio. RTTY and PSK31 there are many other digital modes that work using a sound card. Lots of things use FSK like your wifi router, digital police radio (DMR digital mobile radio) P25.
Incredibly entertaining, as well as very amusing. I live for content like this.
This is mindblowing! please, keep making videos like this one! :D
Well now I'm really feeling old. Equipment I worked on in the field for United Press International in the late 80s is being put into a museum, and some people watching look at this stuff like it's prehistoric wizardry. Holy crap, no wonder my beard is gray! Aah, but I have one up on the techs of today: Back then, especially as a field tech, you had to be a mechanic as well as an electronic tech. Be glad, young techs, you don't have to figure out what the platen is and how to replace the damn thing (without getting black carbon ink all over your tie and white shirt).
I have one of these on my desk at the office, about a mile away from the building they're made.
I'd love a collaboration with CuriousMarc. Very interesting equipment he has.....
2:22: you should save that for breakfast. If it doesn't go down well, try flushing it with the contents of a lava lamp or a snow globe.
Very cool! I've got a Minicomm or two in storage somewhere; I picked them up from thrift stores years ago. I need to give them another look.
(I grabbed them out of general technodesire, but I'd been thinking of them since a deaf friend had stayed with us for a visit a year or two before.)
So, this is the first form of text messaging? This is epic!
All I can say is... SO F****N COOL!
I got one of these at the thrift store I work at a while ago
Fantastic piece of technology right there! Thank you for sharing this!
I love the sounds these things make, including the clacky keyboards. Also just realized, I think anyway, that Pink Floyd used telephone exchange sounds in one of their songs.
New Build idea: teleharmonium
en.m.wikipedia.org/wiki/Telharmonium
ha thats pretty much the plan
So it says “Do not eat“
So ill be 𝗺𝘂𝗻𝗰𝗵𝗶𝗻𝗴 on that later
Im still laughing 😂
At 4:00 it sounds like the beginning of that memey Sonic the Hedgehog song
lol, that would be fun if people from the internet could trigger / operate the devices you have there at the museum whilst having visitors.
Haunted house.
I was surprised to see that backspace was a feature! *User has deleted this message*
2:15 I've wanted to know this for some time, weirdly. I couldn't quite place the accent but I used to know someone from Corby so it's not a surprise.
Wooow it was very fast to translate and show messages. Impressive good old tech !
I remember using BBS and text games with these :P
record a load of secret messages on mp3s that shuffle or are number specific and play it back as messages in a treasure hunt on the mincom 5000 with hints.
They used this tecnology as a secure radio coded text message, via audio over a (fx) radio in danish military 1990s. A mil version, in handheld size would transmit a ultrafast burst “tweep” that could only be understood by a simular mil version, that used the same keycode. Then the text messages could furthermore be coded if you wanted. Very time consuming, indeed.
Super cool!
Great find!
Cat believe they are New In Box.
It looks like what he has is a hotel pack, to loan out the units to guests who need them. So not new but complete.
I have an incredible urge to type on those.
If you're able to use an Arduino or a raspberry pi to decode the data in real time. It would be cool to setup a website
which allows you to see the raw data and the encoded in text in real time being sent across the museum (using a websocket or something similar for the real time part). The website could be used to listen to real time calls from the phones
@2:51 you kind of said "weird science"to the tune of Jolly "Green Giant" sweetcorn adverts....
Beautiful VFD on those units!
These sounds are wandering into Kraftwerk territory. Lol
Awesome.
Yeah in the states we call them TTYs(as some other commenters have said), there are certain abbreviations we use to on the keyboard as well as verbally to the Relay Operators law.lclark.edu/live/files/8674-2011-conference-darling-2
Fun fact, command prompts on Linux and macOS still write to a special file called /dev/tty001 (i.e. teletype 001) because these devices were used to input text to the computers in the super early days
If you slow the video down to 0.25 speed when those tones are playing at 7:10 region, you can hear they do sound different to each other.
Bro you are a genius! That’s because you got great taste in music! 🎹👍😎🎹👍🎵🎵🎵🪗🪗🪗
It's really cool to see and hear all that stuff working. I wonder if you could come up with a way to play a synthesizer over the phone line?
en.wikipedia.org/wiki/Telharmonium
I hope you find a Tele-Typer. Then you can combine it with the Teletubbie Organ
I wonder how hard it would have been to incorporate TDD support into 1200-baud or faster modems? TDD devices tended to be rather specialized and expensive, but if anyone with a PC and modem could talk to a TDD that would have greatly increased the number of people with whom deaf people could communicate.
I just wanna go trough all the electronics i gathere from work over the years and visit the musup to drop stuff off aswell xD
Too slow for binary, huh? I like the old stuff though.
I found an old hard drive once (get this) It was about a little bit bigger than 1/2 the size of a shoebox and had a whoppin 5 megabytes. No typo there. 5 (five) MEGAbytes. And it was SCSI too. Very sophisticated for its time. I kinda wish I kept it in tact, but the two neodymiums in it were huge N52s.
listen to the thock on those keyboards .......ooh yaahhhh
This is so cooooool
I remember seeing these in movies... also the old acoustic modems for 56k internet !!
accoustic was 300 baud not 56400
@@irvineshort google it..
Yeah saw one in matrix 1999 ))
Awesome I reamer in the 90's this kid across the canyon had one of them he used it for hacking peoples bank accounts
8250 UART can actually work with 5 data bits 1.5 stopbits.
this is so cool
OK so- anybody else thinking to themselves, this is exactly how language might be encoded into something like birdsong, simply using a code and frequency we humans have no handbook to explain? If something as complicated as the written english language can be translated into short but 100% translatable bleeps, surely a bird language could skip the middleman and encode entire concepts into their songs. Two songs back and forth that sound identical to us, but who knows what kind of detail they can produce with the subtle fluctuations of their pitch?
Yeah most definitely
Please never stop going down rabbit holes
Guinness is good stuff!
Do they use mechanical keyboard? I love that sound. My granddad was HAM operator when he was alive and he had class A license is the highest, it requires you to pass 16 words per minute Morse code. But sadly he is silent key since 2000. Iam missing him alot.
Some of them do. I bought a Minicom IV on ebay a while back (no idea why) that had black keys with white legends that were manufactured by Cherry and used an MX grey for the spacebar and Alps SKFL switches for the other keys (using adapters to fit the MX keycaps to Alps mount switches).
Hammond Organ (or Wurlitzer)
The lamp must be for a ringer but that doesn’t make sense since you have to place the receiver on the cradle… strange
Since this is 'no computer' so no biggie, but it's actually using 80C31microcontroller not 8082 (which are actually years). 80C31 is romless (but still has 128 bytes of ram) CMOS version of Intel 8051 microcontroller.
