[GreenKeys] teletypes still in production use?

[Sheldon Daitch]

Jack,

I can't tell you there isn't all that mechanical gear hiding away somewhere,
but when you consider all the transistorized comm gear that is being used
for so many circuits, I'd be surprised if the TTYs will have circuits
to use.  

Far too many USG circuits are on commercial systems, and it might be
interesting to find out how much EMP proofing there is on the commercial
systems.
