Teletype Model 15 - How Does It Work?

[@DawidGabriel]

Electromechanical wizardry at its peak... I can only bask in the glory of my IBM Executive Model C Typewriter. Excellent video!

Great explanation of one of these mechanical marvels. Superb engineering skills went into designing these things with no CAD to check for interference, you wonder how many iterations it took to get the design right. The designers have my utmost respect.

I had a model 15 teletype. It was used by Germany till the end of WW2. After that it was used by the Allied Press. It was then used by the Canadian Pacific Railway. It was then used as a radio teletype by a Ham. I got it in 1978 to use with my SWTPc. The only mod I did was to increase the current from 20 to 60 MA with an external circuit. Later I found it would run on 20 MA. In those days in Canada it was hard to get a used or new printer for a reasonable price. I used an MP-C serial interface to run it. There was a mod to BASIC so that you could print. I later donated it to a museum. They took it, but never put it on display. I still have the Mod in S1 format. I made lots of Snoopy calendars for friends.

The concept as to how these machines stayed synchronized always intrigued me and I could never find any info in this until you explained it in your video. Thank you for posting this!

Damn! This was fantastic. The basis of the current internet are right here. Encoding and decoding of physical zeroes and ones on the wire. 👏👏

Very well done. Thank you.

Very informative. Well done. Thanks.

Wow, this machine is amazing ! To me it's like a remote control typewriter/printer. The basic design shows sheer mechanical genius there is nothing primitive about it at all !!

I had a model 14 repererator as a kid. Watching this video brought back some very fond, nostalgic memories. Thank you for an excellent job of explaining how the system works. Good work!

Fascinating look into the workings of the teletype!

Great stuff! True beauty. And the explanations is understandable too. Thanks!

IDK where you'd be able to find one, but it would be cool if you had a look at the Ascota 170

I'm way out in left field, but I've gotta say you are so careful to not show your face. I guess you simply don't need to.
