          1.0   RELEASE ABSTRACT

                This is the initial release of CPU microcode for CP18 systems running
                the VS/VM Operating System.


          2.0   PREREQUISITES AND DEPENDENCIES

          2.1   HARDWARE PREREQUISITES

                   Supports the VS 18000 Series CPUs.


          2.2   SOFTWARE PREREQUISITES

                VS/VM Operating System Version 2.05.00 (or later).

                SYSCON version 3.31.00 for Classic PC's

                SYSCON version B3.31.00 for industry standard PCs.


          3.0   Restrictions and Special Considerations

                This microcode can emulate older CPU types via an SCU software switch.
                If the switch is set to a CPU type other than CP18, the following
                microcode version numbers are reported to the VSOS:  CP16)16.83.82,
                CP14=14.83.82, CP12=12.83.82, CP10=10.83.82 and CP8=08.83.82.



          4.0   Enhancements

                None.


          5.0   Problems Corrected

                None.


          6.0   Known Anomalies

                None.


          7.0   Media Contents

                One MSDOS format 5 1/4 inch DSDD diskette with one file containing the
                CP18 microprogram.  The file identifier is "/scu/o188202.c18".  This
                file occupies 143360 bytes.


          8.0   Installation Instructions

                From the SCU Maintenance Menu on the SCU, select the Set Console
                Defaults option and set the CPUCODE default to be the new microcode
                version.  Then, select the Install SCU Software function, place the CP18
                microcode diskette in drive A, and hit the Execute key.  The next time
                CPU microcode is loaded, this microcode will be loaded.
