     PRODUCT NAME:  DEC SoftPC for VMS, Version 2.2      SPD 32.18.00

     DESCRIPTION

     DEC SoftPC for VMS provides VAXstation users with the ability
     to operate DOS based software. The SoftPC product emulates an
     IBM[R] PC/AT system (real mode only) using standard VAX hardware
     and VMS software. A DOS application functions in the SoftPC
     environment as it functions on an IBM PC AT providing it does
     not require special hardware, protected mode memory or copy
     protected diskette.

     DEC SoftPC supports DECwindows as well as the VT220. As such,
     it can be executed on any VMS system and displayed on a VT220
     or a local or remote DECwindows X Windows display station. For
     example, a VAX 8600 can be used for execution and a VAXstation
     2000 running the VMS Operating System can act as the display.
     Additionally, it supports the DECwindows text cut and paste
     facility.

     The performance of the SoftPC facility is dependent upon a num-
     ber of factors as well as the speed of the processor upon which
     it executes. A VAXstation 3100/38 system yields slightly under
     6mhz IBM PC/AT CPU performance with arithmetic applications.
     Graphics applications may be slower.

     Applications used with the SoftPC emulator (except those DOS
     utilities included with the SoftPC software) are not Digital
     licensed, warranted or supported products. The user must comply
     with the terms and conditions of each application software
     license agreement in effect between the user and application
     supplier.

     Communications applications may not operate in a like manner to
     a real PC due to differences in signalling on the VAX processor
     and the PC processor and the way in which the VAX processor han-
     dles interrupts. Many communications programs do work correctly
     and it is recommended these programs be tried before purchasing
     SoftPC.
