[GreenKeys] TTYs in news service

Sam:

I am in the process of rebuilding my Model 28 KSR and I cannot find anything 
that tells me how the signal line goes through the keyboard signal generator 
and the printer coils.

I measure the resistance of the two signal lines that come from the 
machine's filter and get 165 ohms.  If I put enough voltage to get 60 ma 
through the load; I get nothing at the keyboard signal box or the printer 
magnet.

Any suggestions would be helpful.

Thanks.
