Align the notched comer of the coprocessor with the

notched comer of the coprocessor socket. The notched

corners must be aligned for the coprocessor to fit into the

socket, so be sure the alignment is correct before you

proceed to the next step.

Caution

the math coprocessor is inserted in the wrong position,

it could be permanently damaged.

Gently push the coprocessor into the socket, pressing

evenly on all sides of the coprocessor, as shown below.

If the coprocessor does not go in smoothly, do not force it-

pull it all the way out and try again, keeping it straight as

you insert it.

It is completely inserted when the surface of the coprocessor

is flush (even) with the surface of the socket. Examine the

coprocessor to be sure it is inserted all the way into the

socket.
