Jeff's  comments on his Lorenz Lo15 spurred me to show what I have been 
working  on.

Thanks to Ed# for alerting us to the East German T-63.  One of  my 
friends and I bought it and it arrived here from Slovakia in reasonable  
shape. It is unique in that it has three levels of "shift": Latin  
characters, Cyrillic characters and Figures.  The "Blank" character  
[00000] shifts to Cyrillic.  This model is a clone of the Siemens  T-37 
and was manufactured in East Germany for the Soviets from the early  
1950s up into the 1980s.  The T-63 was the model used in the original  
Washington-Moscow Hotline to receive the Russian's messages. (US  
messages were sent from a M28ASR.)

The T63 includes a reperf and  the unit also came with a tape reader and 
a Telex box with loop supply (40  ma, with series coils).

The code for the Cyrillic characters was  assigned with similar Latin 
sounding characters having the same  code.  eg, if you send [11111] 
[01010] it prints "R"
if you send [00000] [01010] it prints "P"
See the enclosed  printout. The only difference between the data sent to 
the two lines is  that a [00000] was sent between them.

I've been cleaning it up and  lubricating it and it runs pretty well with 
a continuous stream of data  (like from a tape or MMTTY).  But I often 
get the wrong character if  I just type one character at a time.  
Apparently something not quite  right in the selector mechanism, which is 
pretty compact.  I have  manuals for the Siemens T-37 (thanks, Henning), 
but they are in German and  I can't read it. I thought I could figure 
things out from the diagrams,  but so far, they haven't been much help.  
So I'm still digging into  it.

Have fun,

Duncan
