IBM Mainframe Core Memory, 1959:

IBM Core Memory

Likely NOT a 1401, but rather from some other as-of-yet-unidentified IBM mainframe.

Inner cover has signature of IBM engineer dated Aug 4, 1959

The signing engineer worked on the 1401 during that time, but an informed source says it’s not from a 1401. Nice historical piece with signature.

I welcome any info on its origin or value.
