What might be useful would be to offer all the parts that Mibo requires that are not in 2 mindstorms sets. Otherwise it (...) (23 years ago, 12-Jul-02, to lugnet.robotics)

That is very interesting Jason. It is interesting that mm_free_mem() returns a 16bit value using a 32bit return code.

While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex.
