More Bull For Nec
-- The Japanese computer giant, NEC Corp., plans to raise its stake in ailing French computer maker Groupe Bull from 4.4% to over 10%, according to sources close to the company. Bull declines to comment. NEC seems to be mainly buying a bigger share of the French market. In return for its roughly $100 million investment it hopes that its hardware sales to Bull will quadruple in 1994 to $200 million.
