Apple Computer Inc has lured Joseph Graziano back from Sun Microsystems to reassume the post of chief financial officer which he held from October 1981 to May 1985, and he gets the additional title of senior vice-president: he replaces Deborah Coleman, who has been on medical leave of absence since December and wants to return at a lower level; at Sun, William Raduchel, vice-president of corporate planning and development, becomes acting chief financial officer while the company looks for a permanent replacement.
