Well, not to answer for Stuart, but the interfaces are the Pico Systems PPMC board set, which is a modular set of boards that plug into a motherboard. There is a 4-axis encoder counter, 4-axis 16-bit DAC and a digital I/O card with 17 inputs and 8 SSR outputs. Up to 8 boards fit into the motherboard, which can be daisy-chained together. This all connects to the PC through one parallel port. All the boards are connected together for simultaneous position sampling, DAC update and E-stop.
