[GreenKeys] ASR33 punch reader control line

[COURYHOUSE at aol.com]

folks  it says  twx on modem... but  also says   ddd    so I assume it is!? 
 not a telex? even though it has   western union   stuff on it!?  runs... 
keyboard a little   sluggish   but  will not  carriage return  but   does  
line    feed.  (  go I guess I need a  service  hint for the no return)  I 
have not  even popped  the  case  yet.  
 
what is the interface between the modem and  the   tty?   current  loop or!?
 
I need to  find the  metal trim strip and a knob  for  the     front of the 
beast.
 
all the years of  working  with these  in the old   times   i never had any 
twx. or telex ones... they  all  came  off computers...
 
we have  3  rooms  of  new  displays...  so   the   maint.on machine  stuff 
is  stacking  up!   have this one  the 28 stuck keyboard and the   other  
28  that  linefeeds all the time!  argh!
 
 
thanks  for any and all  elp  guys

Later model TWX would be converted to ASCII 33 with a UCC-6, some  cover 
parts and a tape reader solonoid in the printer change.  TWX soloid  is 48 
VAC.  Needs 120 VAC or you will get smoke.

Well you can convert a TWX to Baudot so they are not that worthless HI

 Yeah, when you find a 33 ASR on ebay, if it has the DEC computer mod 
installed, 
 those go for big bucks to people who are trying to restore old DEC 
computers.  
 The TWX models, on the other hand, are almost worthless in terms of $.
