SUN DEMONSTRATES NEW MECHANICAL CAE/CAD/CAM SOLUTIONS
AT 1989 NATIONAL SPRING DESIGN ENGINEERING SHOW
 
CHICAGO-- April 24, 1989-- With the addition of five significant new
vendors to its mechanical computer-aided engineering, design and
manufacturing (MCAE/CAD/CAM) portfolio, Sun Microsystems continues to
offer the design engineering community more UNIX    application
software than any other technical workstation vendor.  According to the
company, 12 of the top 15 MCAD software packages run on Sun computers.

The new solutions are from Adra, CADAM, ICAD, McDonnell Douglas and
Prime Computer.  Most of these will be among the products demonstrated
April 24-27 at the 1989 National Spring Design Engineering Show.

Many of the MCAE/CAD/CAM software solutions are available for Sun's new
SPARCstation TM  computer families, based on the SPARC TM  RISC
microprocessor.  Most packages are also available for the
Motorola-based Sun-3 TM  product family, including recently introduced
desktop and server models.  MCAE/CAD/CAM software is also available for
the Sun386i TM , the workstation that pioneered the seamless merge of
MS-DOS and UNIX applications on one screen.

Sun's independent software vendor program, called Catalyst, today
consists of 1,500 vendors offering 2,300 software products.  This
includes 500 SPARCware TM  applications that run on any SPARC system,
from Sun or other manufacturers.  More than 150 Catalyst packages are
MCAE/CAD/CAM applications, with a great many available for SPARC-based
computers.

Sun's MCAE/CAD/CAM software solutions span the entire design
engineering process, from solids-based conceptual design through
engineering analysis, detailing and drafting.  Leading packages are
also available for downstream manufacturing processes like numerical
control programming, tool path verification and factory simulation.
Equally important to the design engineer are word processing, database,
spreadsheet and electronic publishing programs available for Sun
systems.

New MCAE/CAD/CAM Solutions

  Adra Systems, Inc., announced that it will resell Sun-3 workstations
and servers as the platform for its popular CADRA-II design and
drafting software and the CADRA-NC multi-axis numerical control
programming package.  Adra's industry-leading price/performance makes
it a preferred solution for mechanical design and drafting, numerical
control, and engineering and drawing management applications.

  CADAM, Inc., has ported its popular PROFESSIONAL CADAM software to
SPARC-based Sun workstations, including the new SPARCstation 1,
SPARCstation 300 and Sun-4 TM  SPARC products.  Sun offers superior
connectivity for PROFESSIONAL CADAM users, with a broad range of
networking services and protocols, including IBM 5080 emulation.  This
is especially important to the many CADAM users who have mainframes.

  ICAD has announced that its ICAD System, a knowledge-based software
product for mechanical design and manufacturing engineering automation,
is available on Sun's new SPARCstation product families.  The ICAD
System, which adds product modeling to conventional CAD, extends the
design process beyond graphic modeling.  With it, engineers build a
product model describing design, engineering and manufacturing
processes.

  McDonnell Douglas recently signed a $25 million OEM agreement with
Sun under which it will resell Sun-3, Sun-4 and SPARCstation systems
bundled with its powerful Unigraphics software.  This will be McDonnell
Douglas' first UNIX-based RISC product offering.

  Prime Computer, Inc., now offers the Personal Designer Sun386i
Edition, a UNIX version of the popular Personal Designer 3-D CAD
software previously available on DOS-based microcomputers.  The Sun386i
Edition enables users to take advantage of UNIX, offering increased
networking capabilities, faster processing and the ability to handle
more complex applications.

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.
