• Be SURE to use an IC socket for IC1 (the PIC processor). There will be other RetroGames and you will need to replace this part to play them.
• Be CAREFUL about the direction the ICs are mounted. Line up the notch on the board with the socket or IC.
• Use the 7-pin sockets to mount the display. It needs to be mounted higher than the screws holding the battery holder.
• The pins on the transistors need to be shaped into a triangle and mounted on the board with the flat side facing the display.
• Unfold this manual to see a picture of mounted transistors and more hints.
