3900/3950HD/3950C  (250-3580/86/87)   Math Coprocessor  Faxback Doc. # 2705

NOTE:  The 387SX Math Coprocessor can be ordered from Third Party
       Products.

The Notebook is designed so that an optional 80387SX NUMERIC coprocessor
can be installed in it.  A math coprocessor takes over the calculation
intensive work from the microprocessor.  This frees the microprocessor
to perform other tasks.  This results in a substantial increase in system
performance, particularly when one uses calculation intensive applications
such as spreadsheets or vector graphic (drawing) programs.

This is a service center installed option.  If you decide that your use of
the computer indicates that a coprocessor would be beneficial contact your
local Radio Shack store to order the Math coprocessor.
