Prior to the advent of the microprocessor, a computer was usually built in a card-cage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires ; in very old designs the wires were discrete connections between card connector pins, but printed circuit boards soon became the standard practice.
