Just a wild-ass guess, but I suspect that a typical CDC 6600 system would
have had a printer that logged console interaction?  I'm only suggesting
that a CRT console with no logging was a bad idea.

Of course, in principle the logging could be to disk or tape, but I don't
think most "machine-room" people would have trusted that nearly as much for
a console log. One wants a log of what happened on the console even when
the system was not working well.
