A Point-of-Sale networked computing system includes a workstation with a first Personal Computer (PC)-based controller, a workstation with a second industrial PC-based controller having different performance characteristics than the first controller, and an Ethernet network coupling the workstations. The Ethernet network may include home-run or star Ethernet topology, and the controllers may be TCP/IP addressable. The computing system may be used in a restaurant, kitchen, shop, or department store. The computing system may also include a bump bar keyboard or keypad and a monitor coupled to the controllers Another Point-of-Sale networked computing system includes at least two workstations, each of which includes an industrial non-PC-based controller, and an Ethernet network coupling the workstations. Yet Another Point-of-Sale networked computing system includes a workstation with an industrial PC-based controller, a workstation with an industrial non-PC-based controller, and an Ethernet network coupling the workstations.
