Replica 1 plus Users Manual Step 8: Install 2 pin jumpers. Hold one jumper and install it near the EPROM. While holding the jumper, turn over the replica 1 and place it on the work bench. Allow the work bench to hold the jumper while you solder into position. You may need to adjust the replica 1 to make the jumper stand straight up before soldering. Repeat this process for the jumper near the ASCII keyboard connector. Figure 17: Jumper Step 9: Install the LED into its location. The + lead is the longer lead. Make sure the LED goes all the way flush with the board. You may have to wiggle the LED a little to get it all the way flush. Hold the LED into position and turn the replica 1 over.
Solder the LED pins and cut the extra length off. Figure 18: LED light Step 10: Install the 8 .1uF capacitors into the locations C1-C8. These capacitors are identified by 104 on the them. These are not polarized so they can go in either direction. They vary by manufacturer so you may need to adjust the pins to fit them into the board. I usually bend the pins away from one another to hold the capacitor in place, then turn the board over and solder the pins. Cut the extra leads off. Figure 19: .1uF capacitor Step 11: Install the two .01uF capacitors like you did with the .1uF capacitors. ID is 103M on the caps. They are not polarized so you can install them in either direction as well.
