Two land systems optimised for simplified installation of two types of components of different technologies. A system of links by solder bridges, allowing tracking which is modifiable and alterable at will, in order to link these various components together and to standard output connectors. For as close an approach to the final productions, the chosen support corresponds to printed circuits used in industry. That is to say, an epoxy glass plate of 1.6 mm in thickness, covered on both faces by a layer of tinned copper, of 35 microns. These circuits are to the standardised EUROPE, DOUBLE EUROPE and P.C. formats. The lands with the conventional format are spaced at a pitch of 2.54 mm, and pierced at their centres with a hole 0.9 mm in diameter, allowing component leads to pass through for "interface" links. The output connectors are to Europe standards, but can be modified as the user wishes. <IMAGE>
