I calculated the acceleration of gravity once with a light sensor, touch sensor (for timing purposes), a ruler, and ROBOLAB 2. It didn't involve a whole lot of data so it didn't make it into the Sample Projects of ROBOLAB Investigator, but some (...) (24 years ago, 20-Aug-01, to lugnet.robotics.rcx)

Hi, has anybody taken a look at the ROM of the RCX 2.0? Are there any significant changes? I'm looking in particular for changes in addresses of routines or data areas that could lead to interoperability problems. Jürgen (24 years ago, 16-Aug-01, to lugnet.robotics.rcx)
