NQC is intended to write programs that run on programmable bricks (RCX, Cybermaster, and Scout). The 9751 is more like a peripheral for the host computer, so you'd need some tool that writes programs that run on the host. I think I've seen (...) (23 years ago, 12-Jan-02, to lugnet.robotics.rcx.nqc)
