Unisys Corp chairman James Unruh warned at the Blue Bell company’s annual meeting that Certain core products, such as mainframes, hardware maintenance, and defence custom products will decline in revenue over time – that group made up 6% of our total revenue in 1993 but growth must come from the other 40% of our business, he said, reiterating that because of the larger than expected first quarter revenue declines, the goal of increasing 1994 revenues has become tougher.
