  Re: RIS 1.0 vs 1.5: which more "desirable"?
 
You will get a few extra parts with the 1.5 version, but the RCX does not have a place to plug in an AC Power adapter. NQC will work fine with both systems. Scout is junior to the Robotics System. Take a tour of the MindStorms sites and you will (...) (25 years ago, 8-Dec-99, to lugnet.robotics.rcx.nqc)

  dll problems
 
Hi, guys. I've got legOS compiled and running pretty happily on a redhat 6.0 and a 6.1 machine, after some fussing with settings, i've figured out that it wants to use /dev/ttyS1 for the serial port... however, once the firmware is downloaded, i (...)

  LNP collision detection Bug found and fixed
