SUN MICROSYSTEMS ADDS PC LAN SUPPORT FOR SUN386i
	      Can Now Connect To Existing PC LANs

BILLERICA, Mass. - May 17, 1989 - Sun Microsystems today announced
that its Sun386iTM workstation now connects to popular PC local area
networks (LANs). By supporting Novell NetWare and 3Com 3+ LANs, the
Sun386i can be linked to more than 60 percent of existing PC networks.

This capability makes the Sun386i the first UNIX workstation to
provide full networking compatibility with existing PC LANs.
Connection to these networks extends the Sun386i's ability to link with
a wide variety of computers through the Network File System (NFSTM).
NFS is the industry standard for hetergeneous transparent file
sharing.

PC LAN connectivity enables users to preserve their investments in
existing PCs and networking hardware and software while taking
advantage of a powerful UNIX workstation. Based on Intel's 80386
microprocessor, the Sun386i is the first workstation to merge the DOS
and UNIX operating systems, allowing users to run either type of
application simultaneously in multiple windows and easily exchange
information between programs. With the new PC LAN support, the Sun386i
can also access PC files, share peripherals and utilize other network
resources such as electronic mail.

Support of Novell NetWare 2.1 running over Ethernet or Token Ring
networks, as well as 3Com 3+ networks running over Ethernet will be
included in SunOSTM 4.0.2, scheduled for release in July. Users can
easily install a standard LAN board in one of the Sun386i's AT bus
slots. PC LAN resources are accessed through a DOS window on the
Sun386i.

According to Mark Bercow, product marketing manager of end user
networking in Sun's East Coast Division, "Workstation or PC vendors of
DOS-under-UNIX systems cannot provide PC LAN compatibility because
either they lack an AT bus or they can't access the AT bus from DOS due
to insufficient DOS integration." Sun's East Coast Division, located
in Billerica, Mass., handles the Sun386i.

		Faster Speed, Lower Cost

The workstation's new level of connectivity was made possible
through an overall 20-fold improvement in AT bus interrupt response,
allowing effective communication with PC LANs. Besides LAN support,
this has significantly boosted the Sun386i's interactive DOS
performance, improving DOS keyboard, mouse and screen response.

In addition to offering faster DOS response and PC LAN
connectivity, 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.

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.
