Replica 1 TE Users Manual that can be installed either direction. While holding the resistor with one finger, bend the pins on the bottom side away from each other so that the resistor will not fall out and will stay flush on the board. Flip the board over and solder the resistor down to the board. Cut the extra lead length off and throw away. Repeat for all resistors carefully making sure each one goes in the proper location. Step 2: Solder in the reset and clear screen buttons. You may need to tape these down before you flip the board over. Step 3: Install the sockets. I prefer to start with the 40 pin sockets but you can do them in any order you prefer.
Please note that one of the 16 pin sockets is a duel swipe older style that goes in the ASCII keyboard socket. When installing sockets, notice the notch at one end of the socket, find the matching notch on the board. Hold the socket firmly to the board and flip the board over. Carefully set down the board so that the socket doesn’t come out. Solder in place. Repeat for the remaining sockets. Step 4: Install the 1MHz oscillator. If you look carefully you will notice that one corner is not rounded. This indicates pin 1. Match pin 1 to the silkscreen (closer to the X1 label). Install like the sockets but clip the extra lead length off. Step 5:
Install the .1uF & .01uF capacitors C1-C11, C12 & C13. They are not polarized so that can be installed either direction. Install the capacitors in a similar way to the resistors where you bend the leads away from one another to hold the capacitor in place so you can flip the board over. Solder and cut the extra lead length off. Step 6: Install the LED. As described earlier the longer lead is the +. Install the LED all the way flush, and bend the leads away from one another like with the resistors and capacitors. Solder and cut the extra lead lengths. Step 7: Install the 40 pin expansion connector (notice there is no incorrect way to install but pin 1 is closer to the reset button.
This will be a little harder to install because the header pins are close together. Step 8: Install the Transistor. Orientate the transistor the same as on the board and insert all the way flush as possible with the board. Solder and remove the extra lead length. Step 9: Install the DC power connector and power switch. The pins on the switch may require adjusting. Step 10: Install the RCA video connector. When you insert the connector into the board, bend the center pin over flat so it lay’s down. Solder pins into place. Step 11: Install the DB9 RS232 connector. Use care when inserting the connector into the board.
Placing a little solder on the large holding tabs helps ensure a firm connector. Step 12: Install the PS/2 keyboard connector. Some versions of this connector come with extra retaining tabs on the left and right side, remove before installing. Use care when installing as this connectors pins are fragile. Step 13: Install the 44 pin Apple 1 slot. Pin 1 on the slot has a dot next to it. Step 14: Install the C14-C20 10uF capacitors. The arrow on the capacitors points towards the NEGATIVE. On the PCB the positive is identified, so the negative is the other pin hole. Mount flush onto the board, bend the leads away from one another and solder. Cut away excess lead length.
