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 256² ferrite core array". We just called it "Big Mem". Here's a picture of the cabinet from McChord's SAGE: http://q7.neurotica.com/Oldtech/SAGE/BigMem.jpg 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. > we have a couple > http://www.computerhistory.org/collections/catalog/102633198 > > and they keep getting mis-identified.
