I also have a LegOS 0.2.4 program that uses two rotation sensors on input ports 1 and 3 as well as another active sensor (the Technostuff Dual IRPD sensor) on port 2. All work flawlessly, no counter drift noted on the rotation sensor. Perhaps it is (...) (24 years ago, 16-Nov-00, to lugnet.robotics.rcx.legos)
