The 2.0 firmware is available separately from LEGO as part of the 2.0 SDK. You can use this firmware with a 1.5 set (or even a 1.0 set). If you are not planning on using the Lego software then the only difference between 2.0 and 1.5 is that 2.0 has (...) (23 years ago, 21-Mar-02, to lugnet.robotics.rcx.nqc)
