            AST PREMIUM EXEC 386SX-20 AND TAYLOR SOFTWARE FOR MODICON 884

    PROBLEM:       While running Taylor's software on Modicon's 884 PLC
                   programmer, the following problem occurs when operating on
                   line through the serial port.

                   The page down key operates erratically.  One out of three
                   keystrokes may be recognized which results in uncontrolled
                   page selections.

    AFFECTED
    SYSTEMS:       AST Premium Exec 386SX-20 systems

    CAUSE:         Incompatibility between Taylor for Modicon 884 software and
                   AST's Premium 386SX-20 system.

    SOLUTION:      This is not a issue that AST can resolve.  Marketing has
                   determined that this problem will not be investigated any
                   further.
