   Use the following solutions with software after installing an Intel math

   coprocessor

   The @NA function in Lotus 1-2-3 v2.01 and early versions of Symphony

   does not work correctly on a system with an Intel387 DX installed. The

   problem has been corrected in Lotus 1-2-3 v2.2. The phone number for

   Lotus Development is 617-253-9150. 

   CadKey released a 32-bit version of their 3D CAD software, which can

   cause errors while drawing arcs and redrawing images. Contact CADKey 

   technical support at 800-CADKEY0   FAX: 203-649-8231

   ASYST Rev 1.56 and earlier are not compatible with the Intel387 DX Math

   Coprocessor.  Contact ASYST for a patch which fixes the problem. 

   A defective math coprocessor can cause unpredictable values in number

   cells. Test your math coprocessor with Intel's CHKCOP program. Download

   the program with your modem available through Intel's online services or

   contact Intel Customer Support.

   The PC Tech Journal, June 1986 issue compared seven versions of Basic.

   Here is their chart on math coprocessor support taken from page 52 of

   that issue. Better Basic was judged the best in the review.



   PRODUCT:             VERSION      8087 / 80287 SUPPORT

   BASICA               3.0          NO

   BETTER BASIC         2.0          OPTIONAL

   BUSINESS BASIC       7.3          NO

   MEGA-BASIC           5.23         NO

   PRO. BASIC           2.04         OPTIONAL

   TRUE BASIC           1.0          YES

   WATCOM BASIC         2.5          YES

   TURBO BASIC`                      YES (BORLAND)

   QUICKBASIC                        YES (MICROSOFT)

   Running Lotus* 1-2-3 rel3.1 on a machine installed with an Intel486(TM)

   SX CPU can cause  zeros or "err" to appear in the cells. The problem

   occurs because the Lotus software interprets the Intel486 CPU as

   containing a built in math coprocessor, which is not true for the

   Intel486 SX CPU.  To correct the problem, call Lotus Development Corp.



   to request an update kit for rel3.1.

   Microsoft Fortran* v4.0 is not compatible with the Intel387 Math

   Coprocessor.  It works fine with the 80287.  Contact Microsoft for more

   information.
