Connections are made vertically between pads. The pair of pads below
each number constitutes the jumper position associated with that number.
Connections can be made in several ways. If an eight-pin header is

frequent size changes are not contemplated, it may be sufficient to solder
wires between the pads and so make the connections permanent.
Connections for 27C256 EPROM should look like in

This involves cutting the etch on the back of the board at jumper
position 2 and adding a connection at jumper position 1.
