Its a shame it wasn't in the complete unit. Unless someone actually erases it, core memory will hold data until the sun swells up, as a red giant, and toast the earth.
One always wonders what one would find on these old cores.

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 256Â² ferrite core array". We just
called it "Big Mem". Here's a picture of the cabinet from McChord's
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.
