SUN AND LYNX TO OFFER REAL-TIME SOLUTIONS FOR THE MANUFACTURING MARKET
   
SunFLASH Vol 30 #14					           June 1991 
----------------------------------------------------------------------------

MOUNTAIN VIEW, Calif. --June 17, 1991-- Sun Microsystems and Lynx
Real-Time Systems have signed a marketing agreement under which Lynx
will port LynxOS(TM), its real-time UNIX(R) operating system, to Sun's
SPARC(R)-based workstations and SPARCengine(TM) embedded board
products.  LynxOS will be the only third-party real-time operating
system that is completely compatible with SunOS(TM), Sun's standard
UNIX operating system.  Customers running LynxOS on Sun systems will be
able to use available SPARCware(TM) applications without modification
or recompilation.

Sun is also investing in real-time extensions for SunOS that will meet
many real-time requirements.  These include a preemptive kernel,
enabling quick system response.  The extensions will be part of Sun's
System V Release 4 (SVR4) version of SunOS, available by the end of
this year.  Customers whose speed or other requirements cannot be
addressed by SunOS will have the option of selectively using LynxOS.

Sun and Lynx expect these solutions to be particularly attractive to
the real-time industrial manufacturing market, which requires the
immediate, guaranteed response time UNIX has not traditionally been
able to deliver.  They are also expected to be popular for military and
embedded systems.

Today's real-time industrial process control environment often consists
of embedded boards controlling, diagnosing and gathering data from
separate processes attached to supervisory computers managing the
entire system.  SPARCengine boards and SPARC-based workstations fit
very well into this arena.

The availability of LynxOS along with SunOS on Sun(TM) systems and
boards will provide seamless integration and a high degree of
flexibility in implementing manufacturing systems.  SPARCengine boards
running LynxOS or SunOS can provide fast and deterministic response for
data acquisition, process control and on-line diagnostics, while Sun
workstations running SunOS or LynxOS can be used to supervise and
manage the overall system.  These systems can network seamlessly with
other Sun computer sytems within the organization handling
inventory/production control, CAD/CAM, MRP and executive information
management.

In addition to running real-time applications, Sun workstations can be
used to develop real-time applications that execute on SPARCengine
boards or other embedded target systems.  Cross-development packages
running on SPARCstation(TM) workstations are available now from Lynx
for Intel and Motorola chip families and will be available for
SPARC-based targets in early 1992.

LynxOS for Sun's SPARCstation 2 will be available in early 1992.  The
SPARC version of LynxOS will be binary compatible with SVR4 SunOS.
Applications for this solution can be developed now on Sun's
developer's release of its SVR4 operating system and will run
unmodified without recompilation when LynxOS is available.

Sun Microsystems is the world's leading supplier of client/server
computing solutions, which feature networked workstations and servers
that store, process and distribute information.  Used for many
demanding commercial and technical applications, Sun's products command
the largest share of the computer industry's fastest-growing market
segment: workstations and servers.  The company, founded in 1982 and
headquartered in Mountain View, Calif., is a multi-billion dollar
corporation doing business worldwide.

Lynx Real-Time Systems, Inc., headquartered in Los Gatos, Calif., is
the leading supplier of true, real-time operating systems that are
fully compatible with industry standard versions of UNIX, and the only
one to support the proposed IEEE POSIX real-time extensions to UNIX.
