Commenting on its reduced second quarter loss (figures, page seven), Data General Corp said that while it wasn’t satisfied with its overall results, it was encouraged by the continued success of its AViiON family of Unix computers, which showed significant growth over the year-ago quarter, and it remains cautious for the short-term because of the weak worldwide economy and because it sees no evidence that industry-wide pricing pressures will abate in the near future; the Westboro company is able to shrug off the small but steady and grinding losses because it still had $196.2m in cash and marketable securities at the end of the quarter.
