DELL OFFERS UNIX SYSTEM V RELEASE 4
AUSTIN, TEXAS, OCTOBER 31, 1990 -- Dell Computer Corporation
(NASDAQ: DELL) today announced that it will offer DellTM UNIXR
System V Release 4, an enhanced version of the UNIX operating
system. Dell UNIX System V Release 4 will provide users of the
company's 386- and 486-based computer systems with the most
advanced UNIX operating system software available. Dell's
enhancements improve performance and compatibility while
providing portability across industry standard computer systems.
Dell is among the first manufacturers of personal computer
systems to offer an enhanced version of UNIX System V Release 4
(SVR4). When purchased in combination with Dell's high-
performance systems, Dell UNIX SVR4 represents a secure
investment in the open systems market, providing users with
complete, industry-standard hardware and software solutions that
feature outstanding price/performance. Dell UNIX/DOS
workstations and workgroup systems are based on the most current
hardware and software technology. By offering Dell UNIX SVR4,
the most complete and versatile iteration of UNIX available, Dell
continues its commitment to provide advanced systems at
aggressive prices.
UNIX System V Release 4 functionally merges the most popular
versions of the UNIX operating system including XENIXR, SunOS,
4.3 BSD (Berkeley UNIX) and UNIX System V, ensuring compatibility
by providing a single operating system standard. Targeted for
use with power workstations and in networked client/server
environments, Dell's UNIX SVR4 provides upward compatibility for
users in the majority of current UNIX installations.
"UNIX SVR4 represents the new standard for UNIX," said G.
Glenn Henry, senior vice president of Dell's product group. "The
robust development environment of Release 4 will ensure the
availability of increased numbers of UNIX software applications."
A number of new features have been incorporated into UNIX
System V Release 4, including TCP/IP network support; the Network
File System (NFS) and Remote File Sharing (RFS); software
development tools; and the Open Look graphical user interface.
Another advantage of UNIX SVR4 is its increased conformity with
industry standards such as IEEE's POSIX 1003.1, X/Open's XPG3,
ANSI X3J11C and the SVR4 Application Binary Interface (ABI).
Dell's offering of UNIX System V Release 4 maintains an
adherence to industry standards, but also includes a unique
combination of features and performance enhancements. Dell UNIX
SVR4 incorporates the most advanced version of the X Window
System (X11R4); the OSF/MotifTM graphical user interface from the
Open Software Foundation; X.desktopTM 2.0 icon-based desktop and
visual file manager from IXI Limited; Merge from Locus Computing
which provides MS-DOSR emulation; and Serial Link/Internet
Protocol (SL/IP) support. Other added features of Dell UNIX
System V Release 4 include the XView libraries which allow
developers to move SunView applications to the X windows environment;
increased XENIX compatibility; and network and device drivers to
support Dell products.
Available in late November, Dell UNIX System V Release 4 is
priced at $995 for the limited (one to two users) version, and at
$1295 for a system supporting unlimited users. Dell will also
offer an upgrade kit to allow users of Dell UNIX System V Release
3.2 to upgrade to Dell UNIX SVR4. The upgrade kit is priced at
$399 and will also be available from Dell in late November.
Dell UNIX systems also offer users added efficiency through
Dell's ability to custom-configure each system during
manufacturing with the appropriate memory, disk drives,
communications cards, keyboard and monitor. Dell UNIX SVR4 can
be factory-installed with default parameters based on memory and
hard drive capacities.
Dell UNIX SVR4 and every Dell UNIX system is supported with
a UNIX technical support hotline and service package. The
package includes a variety of support options including next-day,
on-site hardware service; UNIX operating system support; UNIX-
based application support; and remote system administration.
Dell is an AT&T source code licensee, and has an in-house team of
experts dedicated to user support and problem resolution. The
quality and accessibility of the company's after-sale service and
support program has been repeatedly cited as a factor in Dell's
consistently high levels of customer satisfaction, as reported in
eight polls of corporate customers conducted by PC WEEK in 1988,
1989 and 1990.
Dell Computer Corporation designs, develops, markets,
services and supports a complete line of personal computers
compatible with industry standards. The company is recognized in
independent surveys as having the highest customer satisfaction
level in the industry for its line of personal computers. Dell
pioneered the direct marketing of personal computers in 1984.
