Tom,

"Riceguy" worked for NCR on the older cash register machines, he also  
has a TT-4 made by NCR.  It would be good to get his opinion.  NCR was  
part of at&t but only for a brief period.  Trying to trace the  
telegraph and telephone industry today would drive a researcher mad.   
The lines are like an explosion in a spaghetti factory.
