I think you misuderstood what Larry said (or I misunderstood what you said). I think Larry was saying that you should use the wall wart from the train speed regulator, which is what Lego recommends.

(...) You can do this but it's not recommended. As the RCX 1.0 has a bridge rectifier on the power input, it's recommended you use a 10v AC supply, to avoid buring out the diodes. ROSCO (22 years ago, 18-May-02, to lugnet.technic, lugnet.robotics)

(...) Purist approach is to use a 9V train speed reg and LEGO(r) wires from the speed reg to your motor(s), possibly through the polarity reverser switch to give control.
