I should take some pics.  I have a set of EMM core units in 
a matching 1/2 ATR box that I'm pretty sure went with it.  
Apparently on mission critical applications, they used BiAx 
which was non-destructive readout.

I managed to get history of the project documents from 
Honeywell that document the whole project, too!
