Replica 1 plus Users Manual Step 2: Place the 5MHz crystal into its location and while holding it flush with the board, turn the board over and set it on your work bench. Verify that the crystal is still flush with the board and solder the 2 pins into place. Figure 11: 5MHz crystal Step 3: Insert the power switch so that the black switch portion sticks out off away from the board. Hold the switch and turn over the board and place it on your workbench. Next carefully solder each pin down making sure not to allow any solder to flow across to another pin. Check with a volt meter that no pins are touching. Remember that some pins will contact because the switch is on or off. Figure 12:
Power switch Step 4: Next is the sockets. I like to start with the largest sockets and work my way down. Insert the socket so that the edge with the notch in it matches the board. If you get this wrong, it is ok, it is just a socket and does not matter if it is installed backwards. I like to solder 1 corner pin and turn over the board and check to make sure the socket is flush with the board. Once you check that, solder the remaining pins. Figure 13: 40 pin socket Step 5: Install the RESET and CLEAR buttons. You can fold the tabs to hold the buttons in place while you turn the board over. Solder the pins in place and check your work. Sometimes they shift a little and need adjusting.
