<p>A printed wiring board on which a plurality of circuit elements having a plurality of terminals is to be mounted. This wiring board has a plurality of conductive lands for selectively connecting a plural kinds of circuit elements and a plurality of wirings for connecting a part of the conductive lands to the ground. The wirings are adapted to the circuit elements so that one of the wirings is disconnected and at least one of the terminals of the circuit can be connected to the ground when at least one of the terminals of the circuit in the circuit element to be connected is connected to the ground. By using this wiring board, an electronic circuit embodied thereon can be easily changed and an electronic apparatus such as a computer terminal can be easily modified.</p> |
