Teleprinters (teletypers) (telex machines)
Hello. Did any one from around here got the chance to operate such machines?
Some guys made a device that allows you to use one with an internet conection: https://www.youtube.com/watch?v=p4bQ...re=em-comments |
My father used teletypers while he was in the navy. He sorta described the OTO (operator to operator) process, between ships. The sending ship would call the receiving ship on SATCON and inform them of the HF frequency to which they were trying to communicate on. Receiving ship would then tune to the frequency and begin communications. Most of the time there would be multiple designated receiving and transmitting station onboard. Occasionally, the data would be run through a cryptograph machine to encode the message should it contain sensitive material. He mentioned how the machines sat in standby clicking away like a small steam engine until data was received. All in all, a dated, but necessary process back in the day.

I use one. Not so much regularly but there is a machine plugged into the wall in my bedroom. :D
I bought an ASR 33 in 2013 and a few years I designed and built an all-in-one modem interface that made it onto hackaday. Currently I can dial into remote systems over the phone albeit only at 110bps because more modern BBS's require at least 300bps and I've never had the time to complete a line buffer. I had it in the other room last month playing Lander on an AltairClone. https://www.youtube.com/watch?v=d6QwXOO6X1Q |
Nice looking machine the ASR-33. I didn't seen to many teleprinters with dasywheel.
But do you use internet connection to sent messages? :scratch2: @ smokinJOE : how come that? |
We had one at the station in the 70's. They were pretty much done away with during the computer age.

What station? Radio, tv?

Way back, in the early days of TV news, NBC had several rattling away in the background while the national news was reported. It was real dramatic to prove that the news was promptly reported. IIRC, they were used till sometime in the 70's. :scratch2: |
You reminded me that Zenith once had a Telex department and the Telex number was printed on our business cards. I know I sent/received some things via the Telex department, but I can't remember what, if it was internal (plant to plant) or external or both; either was possible.

One of the local 'all news' stations *still* has background noise of teletypes running in their broadcasts. They eventually fade it out, but it's funny to hear it. I doubt most people even know what that noise is, anymore....

teletype
I have a model 19 teletype in the attic ( WW-2 era). It is motor driven and makes a fair amount of noise when running. Very heavy. I suspect its and older / mechanical version of what the terminals you speak of. Next time I'm up there I'll post a pix.

Nice looking machine! :thmbsp:

We had three at my old tv station in Illinois in the 70's. One for messages from CBS headquarters in NYC, one for the National Weather Service bulletins and another for the newsroom from UPI/AP. The newsroom had another animal of the day...the photo telefax printer. We would get news photos on this ancient beast. It used thermal fax paper rolls so the pic would come out dark brown and white. It was dead slow. UPI Unifax I think.

Anyone remember the Quix machines? Can't remember the manufacturer. Conductive paper on a drum as I recall. Almost every large law office had one. Slow, but state of the art baby! Sticks and stones for sure. This is about the time when dictating machines went from plastic disks to magnetic disks. The next big tech jump would be in 1972, when the cassette came out.
