Keypunch that was on eBay

[Ed Groenenberg]

Hello Roger,

Do you only need to convert the frequency for the motor or for
the whole unit?
If it is only the motor, you might look for a converter which is
used for jukeboxes. Some people here in the Netherlands use a
frequency converter for the motor which drives the turntable,
the rest of the electronics does work without problems on 50Hz.

Regards,

Ed
