Abstract
Last November we reported that magnetic bubble memory devices would be available this year, permitting designers to find out about them first hand. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> The 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. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>
