Something else to consider as well. I also used to have all gameport stuff until I could not get it to work on my newer systems.
I spoke with CH directly on several occasions. The older gameport sticks, throttles, etc were never designed to work on systems that have FSB speeds exceeding 66mhz!! They will, however work on most systems running a 100MHZ FSB (I used to run mine on an overclocked Celeron running on a 117mhz bus, so I know it will). Once you hit the 133mhz and higher busses, forget it, it will lock up the system. I know the FSB should not have anything to do with it, but evidently the keyboard port on faster bus systems is different also and is not compatible with the CH gameport gear.
There is a modification that can be done that may or may not cause it to work on 133mhz bus systems...it involves the removel of a small capacitor in the throttle. CH sent me the literature and I made the mod, but it did not work. The throttle still works fine on my old celeron box though.
Sooo, the bottom line is simple. If you want CH gear and your computer is of newer lineage, get USB stuff.
