Many machines which did NOT have a ferroresonant transformer
could be run from 50 or 60 Hz with no problem. The one
place it was a problem would be getting the disk spindles
turning at the right speed.
Matching the available voltage would be the other detail,
but a standard voltage adjusting transformer would do it
But, the ferroresonant transformers needed the right frequency.
