A processor system comprising a control module (10) and a variety of subsidiary modules or boards (11, 12, 13) connected to the control module by way of a bus and an analog connector line. The control module comprises an analog-to-digital input (16) for receiving a signal on the analog connector line (25) and each of the subsidiary modules comprising an analog element (24, 28, 29) and switch (23, 32, 33) connected for selectively switching the analog element to provide an analog signal on the analog connector line in response to a control signal received from the control module, thereby to identify the presence and/or type of the option board(s) installed in the system.
