Unisys Corp chairman and chief executive Jim Unruh says he maintains an overall cautious outlook for 1994 because of the persistent economic weakness in major international markets: the company hopes to increase both sales and earnings in 1994, but said that business in Europe has continued to deteriorate, and prospects for the first half of 1994 are not expansive although he hopes for improvement sometime in the second half; rather surprisingly, he says that while Japan remains weak, it is in a better position than Europe to recover; Unruh also said the company is seeing very strong demand for its new low-cost 2200 mainframe introduced in September, but is not en-ough to offset the overall decline in the core mainframe business, which contributed $1,900m of business to the company’s 1992 turnover.
