                  SUN PRELIMINARY RESULTS



     MOUNTAIN VIEW, Calif. - October 3, 1989 - Sun Microsys-
tems, Inc.  (SUNW), stated today that based on its prelim-
inary review of the first quarter of fiscal 1990, ended Sep-
tember 30, 1989, it expects revenues to exceed $530 million
and that at this time the Company expects a small operating
profit and, after net interest expense, roughly a break-even
quarter.  This compares with a net loss of $20.3 million on
revenues of $431 million for its fourth quarter of fiscal
1989 ended June 30.

     The company stated that this expected improvement is
due primarily to two factors:  first, higher unit volumes of
new products, and second, expense and headcount controls
that have slowed expense growth compared with that experi-
enced in recent quarters.

     Sun expects to release its first quarter earnings
statement near the end of October.

     Sun Microsystems, Inc., headquartered in Mountain View,
