Math Coprocessor
Replacement
Replace the math coprocessor as follows:
1.
Locate the math coprocessor on the DECstation 316
+
or
320
+
CPU board (Figure 3–6).
2.
Remove the coprocessor using a small, flat-blade screwdriver
to alternately lift each end. While lifting the coprocessor out
of the socket be careful not to damage the socket or bend any
of the pins on the coprocessor.
3.
Before installing the new math coprocessor, straighten any
pins so they align with the holes in the socket.
4.
Make sure pin 1 aligns with pin 1 of the socket. Pin 1 is
located in the lower right corner (Figure 3–6).
5.
Install the coprocessor in the socket by alternately pressing
each end into the socket. Do this until the coprocessor is
firmly seated in the socket.
