This relates to a packaging apparatus for coupling modular hardware (e.g. printed circuit boards) to both the bus of a digital system and to industrial end devices such as relays, thermocouples, etc. A motherboard connected to the rear of a card cage couples a first group of edge connectors on each card to the digital system bus. The motherboard has a plurality of clearance holes therein for providing access to a second group of edge connectors on each card. A dedicated terminal assembly having end device field wiring connected thereto is electrically coupled to the second group of edge connectors of a particular card by either passing a suitable connector attached to the assembly through one of the clearance holes or by coupling the second group to the assembly by a suitable cable which passes through the hole.
