	There are many companies who make cards for PCs to do this kind of
equipment.  Data Translation is one of the big players.  Analog Devices
might have board level produces, but I think they mostly just make
components.  National Instruments makes a large line of IEEE-488 interfaces
for all sorts of machines (I'm sure they have a PC one); it's a bit of an
expensive route, but you could implement your whole control system based on
IEEE-488 devices with the PC as a controller.
