<p>A modular printed circuit construction using visual or other representations (1 to 7) which can be arranged so as to produce a visual pattern in which continuous interconnections between the modules appear (automatically as a result of overlapping of individual representations). The composite visual pattern can be used to produce a unitary printed circuit board. Alternatively the individual printed circuit boards can be combined in a board assembly using a mounting frame or edge connectors. Two dimensional extension is possible. Particular applications include microprocessor systems (including parallel processors using a common memory). Bus lines can extend completely across individual representations or the unitary board. The positions of such lines can be determined in dependence on the number of individual representations to which they are common. </p> |
