Instruction manual

Once you have checked the parts you can start to solder them onto the circuit board.
The easiest way to solder the components is to start with the shortest (parts that lie closest to the board)
and proceed to the tallest. The order is resistors, ICs, resistor network, sockets, capacitor, LEDs, and
40-pin connector. Some components need to be oriented properly, as described below. The larger ICs,
the EPROM and RAM, have sockets, so solder the sockets directly to the circuit board, and plug in the
ICs when you are done.
1. The resistors can be soldered first. They do not have to be oriented.
2. The non-socketed (14-pin) ICs are soldered next . The ICs need to be placed with the little cut-
out toward the left:
