	SMCC INTRODUCES EXPANSION SUBSYSTEM FOR SBUS PRODUCTS

			Gives Three Extra Slots to
	            SPARCstation, SPARCserver Systems

MOUNTAIN VIEW, Calif. -- June 22, 1992 -- Sun Microsystems Computer
Corporation (SMCC) today introduced the SBus Expansion Subsystem, a new
high-performance desktop SBus expansion product that provides three
additional SBus slots for several of SMCC's popular desktop
workstations and servers. The SBus Expansion Subsystem gives users the
freedom to use SBus cards of varying widths and not be limited to a
system's current SBus capacity; SBus cards are available in single and
double widths.  In addition to providing three extra SBus slots, the
new SBus Expansion Subsystem allows increased disk space, accommodating
up to two 424-megabyte disk drives.

The SBus Expansion Subsystem easily connects to the SBus-based
SPARCstation(TM) IPX(TM), SPARCstation 2, the recently introduced
SPARCstation 10 and the SPARCserver(TM) 630 system.  It is housed in a
compact "pizza box" desktop package that connects to the host over a
cable from one of the SBus slots on the host.  The SBus Expansion
Subsystem provides higher performance for bus master devices than
competing products, as well as auto configuration of SBus cards.  In
addition, the SBus Expansion Subsystem conforms to the SBus
Specification B.0 and is IEEE compliant.

Key markets for the compact SBus Expansion Subsystem include financial
services, electronic publishing, electronic design automation and
mechanical computer-aided design, where the additional SBus slots will
allow users to incorporate a wide range of SBus cards.

Since SBus was introduced in 1989, a fast-growing market for
off-the-shelf SBus expansion cards has been created for this open,
high-speed, low-cost I/O interconnect.  Today, there are more than 260
SBus products offered from more than 100 vendors for applications
ranging from communications to video.

The SBus Expansion Subsystem benefits end users, third-party SBus
developers and resellers.  For example, with the SBus Expansion
Subsystem, an application developer using a SPARCstation 2 can combine
a graphics accelerator card, an SBus printer card and a communication
card for multimedia application development.  A system administrator
working on a SPARCserver 630 could use the SBus Expansion Subsystem to
configure a server with several I/O cards and network accelerator
devices, such as Sun(TM) Prestoserve(TM), to allow more clients to
attach to the server.

The SBus Expansion Subsystem, which will be available from SMCC and
SunExpress on July 23, is priced at $2,495.
