 The Front expansion connectors can be populated with pin headers as test points or used to extend another backplane board. The back expansion connector can be used to extend or terminate the bus as shown below.

 Extending the bus on high speed systems (over 4Mhz) might present a problem as the connectors between two backplanes may cause undesired reflections. It has not been tested but the option is there for your choice to try. No guarantees of performance are given. Perhaps one way to minimize the medium transition is to use PCB mounted ribbon cables (eg. Digikey Part number [[http://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/1658525-2/1658525-2-ND/|1658525-2-ND]]) instead of pin headers with connectors & ribbon cables.
