( ) Step 11. Install 14.318 MHz crystal in its location just
above C61. Insert leads and pull down until the case is
1/16" above the front surface of the board. Solder quickly
and trim.
( ) Step 12. Install male Molex connector in location
J10. Position conncctor so the locking clip is facing
the crystal (XTAL), insert shorter pins in mounting
holes and solder.
( ) Step 13. In the jumper area labeled CLK on the assembly
drawing (between U90 and U91), install Augat pins in mount-
ing holes A,B,C,D and E. (Refer to "Installing Augat Pins"
in Appendix IV.) Using #24 bare wire, install a jumper be-
tween the A and B pins and another jumper between the D and
E pins.
( ) Step 14. Install the following IC’s in the indicated loca-
tions. Pay careful attention to the proper orientation. DO
