My parallel port motion control system can do this on the parallel port
(assuming you have EPP or ECP functions on it.)
The card and motherboard set is probably too expensive for this project,
but I will have a single board that will do not only the encoder counting,
but also run stepper motors, solid state relays and limit or other switches.

See http://pico-systems.com/PPMC.html for more info. Look at
the "Universal Stepper Controller" link.
