[GreenKeys] Printing Cyrillic characters on M28

[Duncan Brown]

Working on the East German RFT T 63 printer that has three shifts to 
allow it to also print in Cyrillic (Russian), has gotten me wondering 
about how the M28 would have been set up to print Cyrillic characters.

When I was in the Army Security Agency (long ago), I always wondered why 
they had Kleinschmidt equipment in the comm center, but Teletype Corp. 
M28ROs in the RTTY Monitor section.

To copy Russian traffic, a M28 would not have needed three shifts, since 
the type box could be changed easily. A standard size M28 type box could 
easily be made with Cyrillic characters in the "Letters" side of the 
box. But how do you get the M28 to shift back to the "Letters" side of 
the type box after you have been printing figures?  The Russian (RFT T 
63) standard was to send "BLANK" [00000] to shift to Cyrillic 
characters.  Could the M28 Stunt Box be programmed to shift the type box 
to "LETTERS" on receipt of [00000]?

We rarely used the M28s in my ASA unit and I never had to work on them.  
Does anyone remember anything about M28s modified to receive Russian 
traffic?

Thanks & have fun,
