These look too large to be ROS.  I'm with the other poster who 
guessed that this might be a driver assembly--the multiple turns on 
each core would seem to indicate that transformer action that  
desired, not memory.  If it wasn't IBM, I'dve guessed some sort of 
core logic or  parametron application, but AFAIK, IBM didn't use 
those.
