Well, then if that's the case, then the only way to see if it works is to try it. My Realflight 3.5 uses the USB Interlinkl. I do recall the older version had a different setup with the cable and if so, that may... MAY work, but don't be surprized if it does not.

Buddy boxes are not that expensive, you know.
