(...) 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.

(...) we ' ve told about this thing with Philo few days ago cause he had the same problem. So I' ve made several tests with 4 RCX: 2 RCXv1.0 and 2 RCXv2.0 . 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 (...)
