Recently Stewart and Golubitsky have formulated a general approach to the study of networks of coupled cells.
Their approach depends on groupoids, graphs and `quotient networks'. We present a combinatorial
approach to coupled cell systems. While largely equivalent to that of Stewart et al.,
our approach is motivated by ideas coming from analog computers and avoids abstract algebraic formalism.
