                       AST-3270 COAX II-CUT FUNCTIONAL ISSUES

    AST Data Comm Product Marketing has reviewed all aspects of the following
    functional issues relating to the 3270 COAX II-CUT product (part number
    500564-001).  They have made the determination that these issues will not be
    resolved for this product.

    These issues are as follows:

        - Coax II board fails to operate in a Zenith model Z286LP.  When
          attempting to execute the loader software the user receives shared
          memory errors.  (PR#A60016)

        - The use of the PA3 function is not supported by the CoaxII-CUT
          software.  (PR#A60020)

        - A video adapter manufactured by Metheus, model number VGA1104,
          interferes with the operation of COAX II-CUT.  When attempting to
          load the CUT emulation software, the message "IRMA Mode I/O Address
          (0220-022FH) Conflict" is generated.  The COAX CUT program then
          aborts.  (PR#A60039)
