[GreenKeys] Model 28 signal lines

[Jim Haynes]

There are many variations, which is why each machine came with a
schematic diagram showing how it was wired (at the factory - not
showing any field changes).  Look on 
www.rtty.com/development/teletype/model28KSR/index.htm  for some
typical wiring diagrams.
