               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

               Support for more information.
