Here are some more specific questions that I still have: 1) Can two handyboards communicate with each other from a distance?, either in the same room (i.e. infrared) or via the internet? 2) Besides Interactive C, what exactly are the other ways that (...)

It is amazing this was mentioned just now. I just started reading chapter 6:pbForth of Knudsen's book with the hopes of learning to use my Palm to interact with the RCX. I don't know Forth at all. Is this a good place to start? What should I use as (...) (24 years ago, 21-Apr-00, to lugnet.robotics.rcx.pbforth)
