"Len Over 21" wrote in message ... In article , "JAMES HAMPTON" writes: Heck, anyone who has used one of those old green machines knows how they were. Folks should be very grateful for the modern pc. The electronics are far more rugged than the old teletypes. I've often stared at the 100 word per minute mechanical beasties clanking away and wondered how they could do that without flying apart. Of course, they did break down now and then ....  "Green?" All the ones I've ever worked with were black (old Model 15 to 19) or different shades of Teletype Corporation gray (Model 28 or 33)... :-) Teletype Corporation ought to get a standing ovation for some excellent mechanical design in those old teleprinters. They were robust performers that went on for days at a time needing only to be fed paper and (once in a while) a new ribbon. The old 60 WPM units were tried out at 75 WPM on a few Army circuits in 1955. MTBF went to hell at that speed and those circuits had very high maintenance turn-over. Restored to 60 WPM speeds, they continued on as if nothing had happened. Used the old type cage structure of the manual/electric typewriters. The "stunt box" (literally a box of type) used on the newer 100 WPM models did awesome things, true, fun to watch while waiting for a program's answer back. Never had one "lock up" in some strange mode, though, that including the old all-caps 60 WPM machines with Caps/Figs keys. By 1980 the matrix printer was IN for anyone needing text throughput, honking out 300 WPM with just a polite buzz instead of the clatter-bang of the mechanical teleprinters. My little Epson MX-80 (purchased in 1980) is still operational but it can't be given away in this age of inkjet printers that tosses out an entire page of text in 5 seconds (draft mode, black and white). The only sound from the "old" HP 722 inkjet printer is the paper-advance stepping motor; inkjets themselves being inaudible. But, the Archaic Radiotelegraphy Society (ARS) isn't really interested in communications per se, is it? ARS is all about HOW the communications is done, not the comms' content. :-) Most Best Holiday Greetings, Hello, Len To some amateurs the how *is* important. Witness PSK, moonbounce, and other stuff. Anyone can grab a microphone and talk. Somehow, a lot of folks get caught up in the code vs no-code argument that is getting *really* old. Seems there used to be an am vs ssb argument back in the 60s as well. However, that *how* it is done is important if we wish to further ourselves. Have a merry Christmas, Len, and try to come up with a new argument next year, hear?  Best regards from Rochester, NY Jim AA2QA |
