Hi Colin, This is the answer that I got from my friend Colin.

I also forgot to mention that the Frieden unit came as a two unit set.
One to record and one to play back. It could be used for form letters
like the Robotyper.
Another use for this tape was numerical controlled machining. The tape
was composed on a Frieden like machine and then fed to a numerically
controlled (NC) mill or lathe. These machines are now CNC (computer
numerically controlled), like everything else.
