Installing a Math Coprocessor
Your computer has a socket on the main system board to
accommodate either an Intel 80387 (25MHz) or a Weitek 3167
(25MHz) math coprocessor. You can install both if you first
install a Weitek dual-coprocessor adapter in the socket.
A math coprocessor speeds up the numeric calculations your
computer performs when using certain application software. It
also increases the speed at which graphic images are displayed
on your monitor when you use graphics-oriented 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.
