Who knows how many more would have died if not for the desperately needed help. https://www.facebook.com/GlobalNews/...0859946961771/ Having trouble playing this video down here in the US. Must be due to your Win 10 upgrade. Plays fine on Win 7. :-) Plays fine down here in the USA on my iMac and Samsung Android Tablet. Even works on my prehistoric XP anachronism. Shows up on that teletype screen, eh? ![]() Teletype screen? Back in the day we used a teletypewriter for output with a paper tape reader for input. Hobbyists used Comodore 64,Radio Shack, and other toys to access bulletin board systems and do rudimental computing. Greg seems to have a pretty good recollection of all that stuff. He would be a good resource if you wanted to find out about early day computing. Before I converted to "ET" in the Navy I was an "RM" for two years and was sent to Teletype Repair "C" school in Norfolk to learn how to completely disassemble, repair, reassemble, adjust and maintain Mod 28 Teletype machines. There were two versions on ships and shore stations at that time. One was just the printer section for receiving messages. The other was the full console with the keyboard and tape reader for sending messages. Don't remember much about them other than they had a bunch of mechanical clutches operated by a main shaft that had to be precisely adjusted. The Mod 28 was originally designed to run at 60 words per minute (a "word" being five characters) but they had been upgraded to run at a blistering 100 words per minute. They were 8 bit machines including a "start bit" and a "stop bit". Upon graduation from the school the students traditionally received a card proclaiming that you were now a "Doctor of Teletype Technology". I still have mine. Archaic technology now-a-days but it was a digital format and a predecessor to computers. So was Morse Code, for that matter. NCR used a teletype printer on one Serbs of mainframes for the console output. Forget which model, but was a disaster as a console printer. Was designed to turn on and print an incoming message, then turned off the motor. Very light duty printer. Our use turned on the motor and the shaft never stopped running. Those oil title bushings would eventually cut the shaft so there was a great play in the bearings. Was a pain in the ass to change the shaft and align all the cams. All I remember is a whole bunch of little mechanical cams that acted as clutches. Each was set with feeler gauges. Oh, and a big, red "bakelite" main drive gear for the shaft. It was supposed to self-destruct in the event of a jam or other catastrophic failure on the main shaft to prevent further damage. All in all, they were reliable. They ran 24/7. These were a light duty receive only unit. That was designed to turn on for a message only. Not run 24/7. |
