I've gone ahead and released a new version of BricxCC. Get it while it's hot! :-) There are a few rough edges in this release, primarily in the pbForth console. Also, the leJOS .hlp file was so large I did not include it in the main installer. The (...)

(...) Mine have been apart more often than I'd like, too! :-) (...) My guess would be mostly for increased communication speed. With the higher baud rate, the duration of the 2-byte Spybot/Manas packets is halved. This allows for fewer collisions (...) (21 years ago, 26-Oct-03, to lugnet.robotics.rcx)

(...) Hello Mark, Thanks for your answer, this will keep me from dismantling once again my RCXs ! So it seems that LEGO modified RCX2.0 to get better compatibility with Spybots/Manas. Now a question remains, why did they increased carrier frequency (...) (21 years ago, 23-Oct-03, to lugnet.robotics.rcx)

I think there might be an explanation for this and I've been meaning to post on this topic, but never seem to have gotten around to it! :-) I've opened up my RCX 1.0 and the IR receiver has the markings "TSOP 1138" on it.

It seems RCX emitter is the same in 1.0 and 2.0 versions. But 2.0 receiver is less sensitive (...) (21 years ago, 23-Oct-03, to lugnet.robotics.rcx)

Download one large file (which is, unfortunately, 18.9 MB) and you are ready to go. I've tested it on W2K and it (...)
