                   PREMIUM 386SX/16 AND COLORADO 120MB TAPE DRIVE

    PROBLEM:       When a Wang emulation board is installed in a Premium 386SX/16
                   and connected to a Wang computer, the Colorado 120MB tape
                   drive revision FW63 fails to initialize.

    AFFECTED
    SYSTEM:        AST Premium 386SX/16 with the following system board part
                   number:

                   202360-001

    CAUSE:         Incompatibility between Colorado 120MB tape drive, revision
                   FW63 and AST's Premium 386SX/16 and the Wang emulation board.

    SOLUTION:      This is not an issue that AST can resolve.  The Colorado 120MB
                   tape drive, revision FW40 does operate correctly.  Customers
                   experiencing this problem should contact Colorado's Technical
