Connect wire to Port A (or B or C--matters not) Connect leads to train track Put locomotive on train track. Now, get a RCX (...) (19 years ago, 14-Oct-05, to lugnet.org.ca.rtltoronto)

The next 10 minutes was spent seeing who could "throw" the train motor the furthest. (...) Hmm. As I recall, I could (...) (19 years ago, 14-Oct-05, to lugnet.org.ca.rtltoronto)

Well, you couldn't translate the DCC routines to NQC (if that's what you're asking) because the byte code interpreter used by NQC is simply too slow to generate the correct waveform (by a factor of about 1000!) The DCC routines were written in (...) (19 years ago, 20-Oct-05, to lugnet.org.ca.rtltoronto)
