SUN ENHANCES DOS PERFORMANCE ON SUN386i;
			LOWERS PRICE

BILLERICA, Mass. - May 17, 1989 - Sun Microsystems has boosted the
interactive DOS performance and lowered the price of its Sun386i(TM)
workstation to increase the value customers receive from this popular
computer. Sun cut prices 10 to 15 percent on complete workstation
configurations, which now begin at $8,990, including high-resolution
monitor and disks. Sun expects these enhancements to increase
penetration of the Sun386i into non-technical accounts, such as
financial services. During the past six months, the Sun386i
workstations have been taking sales in these areas from high-end PCs.

Based on Intel's 80386 microprocessor, the Sun386i is the first
workstation to merge the DOS and UNIX operating systems, enabling
users to run either type of application simultaneously in multiple
windows and easily exchange information between programs. DOS keyboard,
mouse and screen response have been significantly improved by the
recent enhancements. Calculation rates for DOS remain at native '386
speed.

"The performance improvements and lowered cost of the Sun386i will
make this system even more appealing to users who want the performance
of a UNIX workstation but have DOS applications that are critical to
their work," said Bill Avery, vice president and general manager of
Sun's East Coast Division in Billerica, Mass., which handles the
Sun386i.

		Improved Bus Response, Connectivity

The Sun386i's unique capability of using standard PC-AT option
cards with existing DOS drivers has been enhanced through additional
software tuning. The result is an overall 20-fold improvement in AT
bus interrupt response. Besides providing a raw speed increase, this
allows the workstation to communicate effectively when connecting to PC
LANs such as Novell and 3Com.

The improved DOS performance, PC LAN connectivity and numerous
UNIX and DOS quality and feature enhancements will be included in the
Sun386i SunOSTM 4.0.2, to be shipped in July 1989.

			Reduced Prices

The lower prices on the Sun386i are highly competitive with
'386-class PCs. Unlike most PCs, the Sun workstation comes standard
with Ethernet, SCSI controllers and an 80387 floating point chip. A
20-MHz Sun386i/150 with 4 megabytes of memory, 15-inch 1024x768
monochrome monitor and 91 megabyte disk drive costs $8,990, down 14
percent from its previous price. A 25-MHz Sun386i/250, with 8
megabytes of memory, 16-inch 1152x900 color monitor and 155-megabyte
disk drive is $18,490, a reduction of 12 percent from its original
price. Standard software includes the SunOS UNIX operating system,
SunViewTM windowing system, DOS Windows and ONC/NFSTM networking
software.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is
a leading worldwide supplier of network-based distributed computing
systems, including professional workstations, servers and UNIX
operating system and productivity software.
