The math coprocessor must operate at the same frequency as the
system microprocessor. For example, use the Weitek WTL4167-33,
designed for 33 MHz operation.

U14 is the empty 121-pin PGA socket labeled WEITEK between the
cache memory and microprocessor. Pin 1 of the socket is on a
chamfered corner that corresponds to pin 1 of the Weitek, which also
is on a chamfered corner.
Check for bent pins on the coprocessor. Gently straighten any bent
pins using a pair of pliers. Install the component into the socket. Align
the pins and press the Weitek coprocessor firmly into the socket,
making sure that pin 1 of the Weitek coprocessor is aligned with pin 1
of socket U14. See the following figure.
