Installing a Math Coprocessor
Your computer has a socket on the main system board to
accommodate an 80387DX, 33 MHz or 3167,33 MHz math
coprocessor. A math coprocessor speeds up your computer’s
numeric calculations and graphic image displays when you are
using certain application software.
It is best to have your dealer install a math coprocessor for you,
since it is a delicate component that can be damaged easily if it
is installed incorrectly.
If you install it yourself, be sure to read the manual that came
with your math coprocessor, if you received one. Then follow
the steps in this section to install it in your computer. Before
you begin, be sure to read all of the instructions and warnings
carefully so you do not injure yourself or damage the
coprocessor or your computer.
