We have done this. That is retro-fitted an RCX with a bluetooth module. It involves hardware hacking the RCX, which will "void the warranty". Don't do it unless you can afford to completely break your RCX, and can afford a spare! Can I ask, are you (...) (22 years ago, 7-Oct-03, to lugnet.robotics)

From what I understand of VVL, CodePilot and MicroScouts: The CodePilot has pre-programed "macros" burned into ROM. Each has it's own id-code, so that's why the book can use a one-barcode "program" for each factory standard model behavior. So, I (...) (22 years ago, 6-Oct-03, to lugnet.robotics.codepilot)
