Floppies were later used for data-entry (1973, 33FD for 3740). In those days, data entry was for "mainframes". That was the "first" to use the soft sectored format, which became the "standard". ("3740 SSSD format") It held same data as 3000 cards. And, it did not require diagonal magic marker lines on the deck, since dropping it did not rearrange the records!
I was thinking files, not data entry. Could one write card data to them?
