Jobs visited university departments and faculty members to sell Macintosh. Jobs met Paul Berg, a Nobel Laureate in chemistry, at a luncheon held in Silicon Valley to honor François Mitterrand, then President of France. Berg was frustrated by the expense of teaching students about recombinant DNA from textbooks instead of in wet laboratories, used for the testing and analysis of chemicals, drugs, and other materials or biological matter. Wet labs were prohibitively expensive for lower-level courses and were too complex to be simulated on personal computers of the time. Berg suggested that Jobs should use his influence at Apple to create for higher education a "3M computer", a term for a workstation with one megabyte of random-access memory (RAM), a one-megapixel display, and one megaFLOPS of CPU performance.
