The machine was reverse engineered by a mathematician in Dayton, OH and

years later. Great story. So NCR did other things besides cash
registers and accounting machines in those days.

The Poles also did a considerable amount of work breaking the Enigma
Code. Because we were able to read the German codes, it has been argued
that the war was shortened by several years.

We also could read the Japanese codes, which help immensely there.
