Joseph, Not to add too much work load, if you have a chance could you give an overview of the proposals out there for the task scheduling and sensor modifications (if any). This could be simply a quick list of lugnet.robotics.rcx.legos threads which (...) (22 years ago, 11-Jul-02, to lugnet.robotics.rcx.legos)

As Steve mentioned, the 23.07. is too late for the announcement of the new name at Brickfest. I think it would be great to do so, so I decided to make the deadline at Thursday, 18.07. I will publish the new name around midnight of the 18.07 and (...) (22 years ago, 10-Jul-02, to lugnet.robotics.rcx.legos)

kenneth, I believe the code you are looking for is used in program.c (for LegOS v0.2.6) When you press the View button (with no program running) LegOS will show you "FREE", press again, you will get the most significant portion of the free memory (...)
