Computer engineers predicted exchange of business data between the U.S. and other countries at speeds of millions of words per minute following the success of a satellite transmission test performed today. Chester Siminitz and C. Fred Woidt of the IBM laboratory here sent messages directly from this IBM 1401 computer to an identical computer in Nice, France, via the American Telephone and Telephone Company's Telstar satellite. The engineers are shown monitoring the IBM 1009 data transmission unit, which converts binary coded decimal signals from the computer into a special transmission code. Voice communication was maintained between the remote computer installations over the other channels throughout the test.". Written on verso left side of image in pencil is "#1419".
