Amdahl Corp is happy with forecasts on Wall Street that it will grow earnings per share by 15% this year, on turnover 15% to 25% up on the figure for 1988, when it did $2.08 per share on sales of $1,800m. The company, which had gross operating margins of 46.2% in 1988, sees these shading a point or two as a result of pricing pressure as IBM tries yet harder to get the 3090S models moving.
