Abstract :
Last November we reported that magnetic bubble memory devices would be available this year, permitting designers to find out about them first hand.1The most important development since then for the computer industry was Texas Instruments´ March announcement of the first commercially available bubble device–a 92K chip–for about $200 each in sample quantities. Of importance as an indication of what the next two years could bring to the market was Rockwell International´s announcement on June 7 at the International Magnetics Conference in Los Angeles of the successful development of a one-million-bit bubble device in its Electronic Research Division.2
