Thanks for checking this out.  This is important to know.  I assume, then, that the duty cycles
are 1/8 through 8/8 as well as off, which would be 0/8.  Can anybody verify this (with a scope or
something)?  I have long wondered whether the duty cycles were linear or followed some nonlinear
curve.

I thought that NQC used the same firmware as the RIS software, and, therefore drove the ports the
same way.  I guess either the documentation is wrong, or the highest or lowest power level is
missing.

operates for all 8.

(...) I have checked this out, and if you use the standard RCX firmware (or other firmware that uses the RCX ROM, then you get the waveforms you are talking about at 125Hz 1/(1ms x 8). You also get polarity information - oh no, I've said too much. (...) (25 years ago, 26-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)
