Yes, this appears to be so. There might be some secret sommand to gain more
access to the CM, but I doubt that you can change the entire firmware in
it, especially since the CM lacks a RAM chip on the circuit board, as the
RCX does.

Atleast the firmware cannot be changed without some hardware modifications,
such as replacing the original H8 microcontroller with a new one, plus some
extra RAM. Perhaps we have to make custom hardware to be able to read the
current firmware as well.
But what we can do, is write programs for our Cybermasters that is based on
Lego's bytecode language, eg using Dave Baum's NQC, or Lego's Spirit.OCX,
in almost exactly the same way as for the RCX. It is true that the CM has
less memory available than the RCX, but they are both using the same
bytecode (with some minor differences). See the reference manual at
www.legomindstorms.com.
If you refer to "hackable" as being able to program using something else
than Lego's original software, the answer is yes, CyberMaster is hackable.

| (...) One quick question, is the Cybermaster software as easy to "hack" as the Mindstorm OS. Any sense in buying both Mindstorm and Cybermaster ? Thanks. -- Kin W. Lau Teaching Associate, Communications And Signal Processing Group, Electrical (...) (26 years ago, 14-Dec-98, to lugnet.robotics)
