|
|
I just snagged another 4561Railway Express. I believe I recall reading that the AC adapter in that will work with my RCX 1.0. Can anyone confirm this? Thanks, Thomas (25 years ago, 21-Jan-01, to lugnet.robotics.rcx)

Can the light sensor accurately distinguish between THREE colors? All the designs I've seen work with two; e.g. a brick sorter, green & red. And if so, what colors are recommended: Red, Green, Blue? Black, White, Grey? Thanks. (25 years ago, 16-Jan-01, to lugnet.robotics.rcx)
