Yes I know! I didn't have the courage to remake another tape. You make one mistake and you are toast. That was like my 5th attempt... At least I got the dinging part right!

[@grossteilfahrer]

Did you ever solve the tty driver issue with XCASE? I figure it should be possible to recompile the kernel with old sources, shouldn't it? I'd really appreciate a solution so i could use my tek4006 with modern linux. At least it can receive 7 bit ascii, but I'd need a shift hack like figs/letters but for upper lower case ascii. Old unixes had the convention to use a prefix escape char for setting the 7th bit on input.

Long long time a go, in about 1980, I replaced a number of teletypes in my company when we installed the first VAX/11 computer. Just out of college, I still had my sense of humour set to a dangerously high level. We punched up a tape, much as Marc did here, and fed it in to a teletype. Two of us then placed the teletype on the desk of the chief engineer, who over saw a design office full of large drafting boards. We set all the switches to auto play, hooked it to the worlds longest extension lead and retreated to the far end of this 50 yard office. And waited.... When the chief engineer arrived, he saw this monstrosity on his desk. He knew we had been installing a computer but as he came from a different era where slide rules were the order of the day, he had largely ignored us young whippersnappers. He stood, looked, peered at the teletype, clearly wondering what it was doing on his desk. As he reached out a tentative finger to touch it, we flicked the switch, it roared in to life and typed "GOOD MORNING MR VERTIGEN. I AM YOUR REPLACEMENT. YOU CAN GO HOME NOW". He put on his coat and headed back to the car park. I managed to catch him just as he was getting in to his car and explain our joke. Somehow, I don't think he ever saw the funny side of it!

I was a newspaper reporter in the late 1970s, when Associated Press and United Press International sent feeds to newsrooms all over the country via continuously-running Teletypes. After a while working in the newsroom you learned to just tune out the noise... until the bell rang, indicating an incoming bulletin. The number of bell rings indicated the level of urgency... I think the levels ran from three bells (ordinary breaking news) up to eight bells... the only time I ever recall hearing eight was when the Pope died. If any of us had heard this Teletype March we'd have had heart failure!

[@simontay4851]

Why would the pope dieing be urgent. I couldn't care less about him.

[@sadiqmohamed681]

Back in the 70s as a trainee engineer at the BBC, I worked on the Saturday sports programme "Grandstand". Towards the end of the show the football ("soccer") results would come in and would be presented by pointing a camera at a teleprinter and having a commentator read them into a lip mic! The teleprinter noise was included at low level. In the early 80s they made an electronic version including the sound FX.

When I went back downstairs to the shack after dinner I heard Jingle Bells being played on my Model 15. Wow! That was cool. Someone has a tape out there for it somewhere. No computers back then. Late 1970's early 80's.

[@russellhltn1396]

I think you need to do the one thing to make this complete: Teletype via radio. It was the radio link that really made Teletype useful as it was. The mode is still in use on the ham bands, so you can make a contact that way.

[@CuriousMarc]

Totally agree. Our 19 in particular comes from the Navy, and was most likely a Radio Teletype. Coming up one day hopefully.

1:44 Long ago, my uncle was a Lineotype operator at the newspaper in Leesburg, Fla. and he told me that he heard a regular bell symphony for much of the afternoon of November 22, 1963. Every few minutes a news flash of the highest priority arrived on the Teletypes with the bell ringing six to eight times, continuing well into the night.

[@arniep740]

This brings back a lot of memories. I am a ham radio operator and had a Model 15 and and Model 19 tty machine hooked up to my radio in the late 60's. We used to talk to other radio operators worldwide, send tty pix back and forth etc. It was fun and eventually went all electronic, thus doing away with the sound, and smell, of this ingenious mechanical contraptions. Thanks for the memories! p.s. Ham radio operators still use Baudot code communications in some instances for long distance communication. It is called RTTY and is actually the second digital mode of communication. The first digital mode of communication was Morse code (also known as CW).

[@pauldzim]

And of course there is the classic movie "The Andromeda Strain", where a piece of paper jammed the teletype bell with potentially disastrous results.

First assignment at my first PCS base, right out of tech school, was to reassemble and adjust a M28 ASR page printer that had been completely stripped down to every single piece and placed in a box. This included stripping the main shaft and disassembling the clutches as well as completely disassembling the function (stunt) box with all its tiny springs. Newbies had 8 hours to get it back together and running with a minimum spread of 50 points on the rangefinder. No one ever made it on the first try. Took me 5 attempts to get the damn thing assembled in 8 hours and another 3 to get everything working right. Later I found out that was the point. To make us practice until we could do it right. Don't miss those noisy clunkers at all.

I still like the Linux terminal over teletype more. That doesn't change the fact that this is awesome. What happens if you run a fullscreen application, like Midnight Commander or Nano, over teletype? Does it retype the screen? Does it not work entirely? Can you use ssh over teletype to connect from that old ass laptop to a modern computer, a server or a Raspberry Pi? What do modern command prompt applications look like? *gasp* Can you use Elinks to go on the internet?!

[@b43xoit]

I have heard Lara's theme from Dr. Zhivago performed on a bank of about seven or at least five standing tape drives having vacuum columns. Also, some rousing march on a line printer. I'm pretty sure this was on the CDC Cyber74, not the Univac 1108. One of the operators remarked that what wowed visitors to the computer room was not the calculations the computer could do, but the fact that it would report on the console when the printer was out of paper (or it may have been something about the card reader or the card punch).
