ISTR reading somewhere that UNIVAC had these well before most other

[ Sounds of rummaging around google]

   http://www.cc.gatech.edu/gvu/people/randy.carpenter/folklore/v5n1.html :

   No punched card devices were provided with the UNIVAC, so the
UNITYPER data entry machine was
   developed. The data entry clerk typed on a keyboard, and the UNITYPER
recorded the values on a reel
   of metal tape. This lack of integration with punched card systems
became a marketing handicap. Many
   prospective customers already had significant investment in
tabulating card systems. When IBM entered
   the computer business, it made sure that it offered computers that
fit easily into existing card processing
   installations. To fill this gap, Eckert-Mauchly developed a
stand-alone card-to-tape unit, which could
   process 100 cards per minute. Since Eckert-Mauchly was an independent
company at the time the design
   of the card-to-tape converter was done, it naturally followed the
market and built a machine that handled
   IBM's 80-column cards. Sometime after the acquisition by Remington
Rand, a version to handle 90-column
   cards was developed.

That would have to be in the early 50's....
