Thanks go to Michael Obenland for pointing out a problem with compiling under the new gcc versions. This caused me to recognize that I failed to include 5 of the latest file versions in 10.5. If you've started to work with 0.2.10.5, please download (...) (21 years ago, 17-Feb-04, to lugnet.robotics.rcx.legos)

Does anyone know where I can find some sample code or demos explaining how to send simple messages back and forth between RCXs using LNP ? (21 years ago, 13-Feb-04, to lugnet.robotics.rcx.legos)

The brickOS team is pleased to announce our next test release. (Can you believe we are days shy of a year since our last?) We will likely do one more before our formal brickos-1.0.0 release.

I tried to look for Visual NQC 2001 on the net but can't seem to find it either. =( The main website no (...) (21 years ago, 13-Feb-04, to lugnet.robotics.rcx, FTX)
