History Of Telecommunication (was: The far beginning of the "Internet")

#1

Post by RTH10260 »

Just cause I happened to stumble over this piece of telecom history:
Heart's Content Cable Station (CA)

Highway 80, Heart's Content, Newfoundland and Labrador, 1 1/2 hours from St. John's.

Imagine... President Abraham Lincoln has been assassinated but London's papers aren't reporting it - it'll take 10 days for the news to reach Europe by ship...

In July 1866, after nine years and several unsuccessful attempts, the first permanent telegraph cable connecting Europe and North America was hauled ashore at Heart's Content. This little Newfoundland town leaped into the history books and remained a global communications hub for over a century. The cable station opened the world to the outport men and women who worked here and remains a time capsule of the communications technology that connected us all right up to the 1960s.

Pretty fake, unless they managed to exactly come up with the design for the DEC LA120 terminal..

Why would the average home need a submarine maneuvering console?

How prescient of the designers of this 1950s "computer" to give it a 1970s Decwriter LA36 console. (I'm sure someone will correct me if I have the model number wrong, my memory is only 4-bit and not parity-checked.)

I think it's an LA120. The LA36 had different switches on the left of the keyboard.

Fresh out of college, I worked in one of the DEC plants that made 'em :blink:

ETA: "The LA120 had a VT100 like keyboard with a SETUP key and LEDs indicating various things. The LA36 has that group of keys on the left to configure baud rate, etc."

I kept several teletype tables (as shown above) with the cutout for the paper feed. Super tough tables that make excellent project benches. But the paper slot baffles our new guys - "What's that for?"

Those rubber cups required a fairly standard design of telephone handset, which was OK in the days when the phone companies provided (and owned) your phone.

Now we're talkin! Those hearing impaired terminals were around for a very long time. Every 911 PSAP had one.

Portland has a long tunnel for the light rail that has ring down phones approx every 750 ft that require monthly testing. Pretty good exercise walking eight miles of tunnel to check well over a hundred.

Not to nitpick excessively, but the Silent 700 wasn't a TDD device. It was a general-purpose computing device. Those of us who lived through this era of computing well recall the Silent 700. If you dreamed of mobile computing, this was your answer; you were really stylin' if you were important enough or cool enough to try to stay connected with this thing at 300 baud while you were out and about.

As I recall (a cousin is deaf-from-birth and had one) TDD's were a bit smaller and they used a different type of technology, such as a one-line LCD screen. They were a bit more portable (potentially battery operated) and if they had a printer, it was often smaller (more like a cash register receipt) than the Silent 700.

As I recall, I checked out connecting my cousin's TDD directly by phone to my printing terminal in the 70s, but that was not possible. TDD's weren't directly compatible with standard ASCII terminals like the one here, because they used a 5-bit encoding (basically the upper case alphabet and a couple other characters) to enable them to use a lower transmission speed on poor quality lines. Ascii was 7 or 8 bit plus optional parity bits, and could carry a much wider range of characters. The 300 baud couplers of the day, like the one on this unit, typically required a high-quality phone line. Damage to the wiring in the house or office that generated noise meant you couldn't reliably move data down the wire, and you'd see frequent connection drops, etc., at 300 baud. The TDD system, which was designed in the 1960s, didn't need high speed because it was only for personal messaging and not running business applications, but it needed the ability to connect on much noisier connections. Business applications required faster speeds as they were sending a lot more information to the user, and were able to require a higher-quality connection to do it.

Customer service centers supporting TDD users may have used general purpose equipment via a protocol converter for operator comfort and productivity, but I am quite certain that standard ASCII terminals such as the TI terminal here were not used by the users out in the field.

Correct. We had a total of TWO :banana: in our math department in Junior High. IIRC, we dialed them to a state university, and, yes, we could write/execute programs on their mainframe. This is what I wrote my first program using at age 11.

Then the learning went to crap as the High Schools went to Apples. :talktothehand:

Those are actually the throttles for the main engines. The large outer wheel is for ahead and the small inner where is for astern.

I spent a few years of my youth in a maneuvering room watching those meters and gauges.

I was a radio operator in the Coast Guard back in the day. I learned to type on a manual typewriter, and used the Model 28, Model 32, and Model 43 Teletype machines. I also did voice communications, including ship-to-shore and air-to-ground.

But this was by far my favorite means of communication:

What happens when you turn them both all the way clockwise?
