                  AST PREMIUM EXEC WITH PC HF WEATHER FAX SOFTWARE

    PROBLEM:       Software Systems Consulting (SSC) produces a PC HF Weather Fax
                   software package that is incompatible with the core logic used
                   in the AST Premium Exec notebooks.  The Western Digital
                   WD76C10 device is not unique to AST notebooks.  The PC HF
                   Facsimile version 5.0 does not properly display the weather
                   satellite images.

    CAUSE:         The Western Digital WD76C10 is not compatible with the
                   software timing of the Software Systems HF Weather Fax.

    AFFECTED
    SYSTEMS:       All AST Premium Exec notebooks, as well as all other vendors
                   notebooks that utilize the Western Digital WD76C10 device.

    SOLUTION:      There is no solution to this problem.  SSC has agreed to give
                   any customers using their software on such a system a refund.
                   Customers reporting this problem should contact SSC at (714)
                   498-5784.
