Adding a WTK3167
A Weitek WTK3167 can be added to a Series 18 AMI Mark IV
CPU/Coprocessor Card only if there is no 80486 installed on the
CPU/Coprocessor Card. You can use both an Intel 80387 on the
Mark IV motherboard and a Weitek WTK3167 on the Series 18
CPU/Coprocessor Card.
When the Series 18 CPU/Coprocessor Card with an Intel 80486
is installed, the 80386, 80387, and the WTK3167 are disabled
and the only additional math coprocessor that can be used is a
WTL4167.
Installing the WTK3167 on the Series 18
CPU/Coprocessor Card
Find the socket labeled WTK3167 in the upper left corner of the
AMI Series 18 CPU/Coprocessor Card. Pin 1 of the socket is on
the corner with the chamfered edge. Pin 1 of the WTL3167 is
near the upper right corner. Align the pins of the coprocessor
with the socket. After making sure that all pins are aligned and
pin 1 is properly oriented, firmly press the coprocessor in the
socket. See the following graphic.
Make sure that there is no 80486 on the CPU/Coprocessor Card
and that the shorting bridges for J1 and J2 are removed.
