I was given a program to install on an ATT 6386 WGS. the program
was written by a professor (Mech. Eng.) using Quick Basic. The
program does a great deal of computations. Running in native DOS
the program will invert and do some calculations on a test matrix
in 20 seconds. Under Simultask (VP/ix) it takes almost 5 minutes.
We have concluded that QB is checking for and not finding the 80837.
Turbo Pascal, AutoCad and Ansys run fine. (Ansys won't run without
a math coprocessor) 

Any ideas or suggestions?

P.S. I expect a slowdown of 30% running under SimulTask. This isn't
      even close.

P.P.S. SimulTask allows DOS to run as a task under UNIX on 386 boxes.
