Replacing the PostScript code ROM SIMM

3.Remove the currently installed PostScript code ROM SIMM in connector P71 by spreading apart the hook-like metal pawls securing each end of the SIMM in its connector. Remove the SIMM. To protect the SIMM from static electricity, slip it immediately inside an anti-static bag.

4.Insert the new PostScript code ROM SIMM in connector P71 (a), and tilt the SIMM down until it locks in place (b). The part number

671-3809-00 is printed on the back of the ROM SIMM to identify it.

When properly inserted, a tab on each end of the connector slips into a hole on each end of the code ROM SIMM. Also, a pawl on each end of the connector latches around each end of the SIMM to lock it in place.
