If this is the first version with the optical sensors there is a USB adaptor that will work for the inputs alone. Generic Gameport to USB convertors will not work. Force Feedback will not work however even with this adaptor and it is unlikely an FFB adapter will ever be made. This means you will be driving the FF motors manually whenever you move the stick.
I bought two of these joysticks about a year ago, perhaps I ought not to mention the price I paid.
