190-161 IBM 4702 PROCESSORS AND 4701 MODEL X03 CONTROLLER ENHANCED
The IBM 4702 Processors and the IBM 4701 Model X03 Controller have
been enhanced by a no-charge engineering change (EC 325258) to
provide users with improvements in microcode-enabling features, new
display device support, and DASD reliability and support.  These
enhancements also allow 4700 users more flexibility in their
connectivity options so that they may continue to add more advanced
functions through the integration of intelligent workstations.  This
engineering change is designed to be used in conjunction with
Release 9 of the IBM 4700 Finance Communications Systems Host Support
licensed program (5668-989).
       Planned Availability Date:  October 5, 1990.
HIGHLIGHTS
o   Enhancements to microcode-enabling functions allow the customer
    to 'grow" current 4700 system environments without the physical
    to 'grow" current 4700 system environments without the physical
    inhibitors of previous releases.  The 'keys" to function enabling
    inhibitors of previous releases.  The 'keys" to function enabling
    may be issued by system monitor commands or from a central site
    using the IBM 4700 Finance Communications Systems Host Support
    licensed program.
o   Functional support in emulation mode for the 3471 and 3472
    InfoWindow (R) displays has been requested by customers who are
    upgrading display devices but wish to continue to use their
    present applications.  A new system monitor command allows the
    device type to be displayed on the screen.
o   Reliability and serviceability have been enhanced to improve user
    productivity and increase data integrity.
o   System monitor and miscellaneous enhancements for EC 325258
    include merge AP option, generation manipulation with IPL, and
    timer-driven single-cycle debugging.
o   The LU-LU pass-through capabilities have been enhanced to allow
    restricted participation for IMS and TSO environments.
