    In the T.O. (http://www.bitsavers.org/pdf/ibm/sage/3-32-0_Central_Computer_System_Vol1_Feb59.pdf), 
that cabinet is called "core memory 1", or 256² ferrite core array". We  just 
called it "Big Mem".  Here's a picture of the cabinet from McChord's 
SAGE:

    I'll have to look through my references to find out when it was deployed. 
That training manual doesn't seem to be on Bitsavers.  :-)  It would be nice 
to find it.
