I've just completed your version of the decoupler device and I must say that it's excellent! 8-wide train builders may want to modify this for clearance reasons though.-Harvey (25 years ago, 5-Jul-01, to lugnet.robotics.rcx, lugnet.robotics.scout)

Make sure that you are targeting RCX 2.0. Some IDEs allow you to set this in a preference. For the command line version, add -Trcx2 to the command. You can also use the NQC_OPTIONS environment variable. See (URL) for more info. Dave Baum (...) (25 years ago, 27-Jun-01, to lugnet.robotics.rcx)
