I didn't look very closely at first and assumed they were socketed,  
but you're right. They are piggybacked.

I didn't recognize it as a delay line. What I have is a printer/ 
memory adapter.

The other question remains, however: was it possible to use the Async  
Adapter for the 3270 host connection, probably in combination with a  
modem of some description? I always assumed that one needed SDLC or  
Bisync to do this in the absence of the obvious (coax) interface.
