I am thinking of using a pc as the controller for a pinball machine. I need info on using a serial or other port to sense voltage changes.

Do you need a 'controller' or a display 'controller'?
Since you want to sense voltage change I assume the later.
Is the voltage change a discrete value (analog) or on/off (digital)? If the pinball machine is a conventional one, then most of the measurements are events (digital).
If you are measuring 8 or less events then you could use the parallel port. For up to 20 there are usb adapters available for under US$100. For more there are digital i/o boards with ports in multiples of 24 or 48.
