All, As I've mentioned before, I have a version of pbForth firmware for the RCX that allows you to control trains modified with DCC controllers. The benefit of pbForth is that you can write, test, and debug your application interactively using (...) (21 years ago, 21-Nov-03, to lugnet.trains, lugnet.robotics.rcx.pbforth)
