          Dear DECwindows Customer:

          Welcome to VMS DECwindows Motif Version 1.0. Starting with this
          release, DECwindows software is offered separately from the VMS
          operating system.

          DECwindows Motif Version 1.0 complies with the License Manage-
          ment Facility (LMF) and requires a license Product Authorization
          Key (PAK). Your license PAK has been enclosed. You must regis-
          ter and load your license PAK to install and run VMS DECwindows
          Motif Version 1.0.

          Benefits of DECwindows as a Layered Product

          We believe that providing DECwindows as a layered product gives
          our customers certain advantages over our previous method of
          packaging DECwindows with the VMS license:

          o  Faster availability of new OSF/Motif[TM] features and re-
             leases. By decoupling DECwindows Motif from VMS releases, we
             can provide new features in VMS DECwindows more frequently.

          o  More flexibility in pricing. We believe that customers should
             pay only for the features they need. Our new packaging lets
             customers purchase DECwindows software only if they need it.

          Same Environment for Both Motif and XUI Applications

          The OSF/Motif graphical user interface (GUI) is the new default
          user interface for VMS DECwindows Motif. The OSF/Motif GUI
          is an open standard, developed jointly by the Open Software
          Foundation[TM] (OSF)[TM] Digital Equipment Corporation, and
          Hewlett-Packard. The X User Interface (XUI) delivered in VMS
          DECwindows continues to be maintained and supported within the
          VMS DECwindows Motif layered product. Because both the Motif and
          XUI interfaces are based on the X Window System, applications
          written to either toolkit continue to run, regardless of which
          environment the user selects.

          Getting Started with VMS DECwindows Motif

          The "look and feel" of the OSF/Motif user interface differs
          from previous versions of VMS DECwindows based on XUI. It might
          take you a little while to become comfortable with this new
          user interface. We suggest that you begin by reading Part 1
          of the VMS DECwindows Motif User's Guide. Another way to gain
          hands-on experience with DECwindows Motif is through the online
          tutorial available from the Session Manager's menu bar. To start
          the tutorial, select the Help pull-down menu from the Session
          Manager menu bar and choose Tutorial.

          VMS DECwindows Motif Performance

          The OSF/Motif interface consumes more memory resources than the
          XUI interface that shipped in previous versions of DECwindows.
          Consequently, you may notice that Motif applications take longer
          to start and use more memory than XUI applications. Once a
          Motif application is running, however, performance should be
          comparable to that of applications in previous versions of
          DECwindows.

          The performance of XUI applications under VMS DECwindows Motif
          Version 1.0 should be equal to or better than performance under
          previous versions of VMS DECwindows.

          Digital is working independently and with OSF to improve the
          performance of DECwindows Motif. We are planning to deliver
          performance improvements in future releases of VMS DECwindows
          Motif.

          Prerequisite VMS Support and Minimum Memory Hardware
          Requirements

          VMS DECwindows Motif Version 1.0 has a temporary minimum memory
          requirement of 12 MB per system. This memory requirement will
          be lowered to 8 MB with the release of VMS Version 5.4-3, which
          contains memory management enhancements allowing support of 8 MB
          systems.

          The prerequisite VMS release for 12 MB systems is VMS Version
          5.4 through Version 5.4-2.

          The prerequisite VMS release for 8 MB systems is VMS Version
          5.4-3.

          Supported VAXstation Hardware

          The following is a revised list of supported VAXstation hardware
          requiring the DECwindows workstation device support:

          o  VAXstation II

          o  VAXstation 2000

          o  VAXstation 3100 (all models)

          o  VAXstation 3200

          o  VAXstation 3500

          o  VAXstation 3520, VAXstation 3540

          For a complete list of supported VAX, MicroVAX, and VAXserver
          systems, please consult the VMS DECwindows Motif SSA (36.09.00-
          A).

          OSF/Motif Toolkit Restriction

          When a DECwindows application is first started, it must estab-
          lish a connection to a workstation. This is called opening the
          display. When the user is finished with the application, the
          application closes the display.

          A single Motif application that opens, closes, then re-opens
          displays can experience problems with display and screen-
          specific data, such as pixmaps. Therefore, we recommend that
          Motif applications not open and close displays multiple times.

          Digital is working with OSF towards a more comprehensive so-
          lution to this problem for a future release of VMS DECwindows
          Motif.
