At least there's one thing that CyberMaster proved - That 3 inputs is not the limit of the H8 or even all the LEGO PBricks.
Clearly CyberMaster have 5 inputs, although 2 of them are fixed just like the 2 fixed motors (which is not as bad as it sounds)
On a second thought, if they are "standard" inputs, why LEGO gave them different addresses in memory?
....
Another subject:
Any of you a have tried boosting the radio tower range?
What about the CyberMaster unit range?
