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?

According to the Technical Reference, Tachocount counts the number of revolutions of the motor shafts (of the two built-in Cybermaster motors ONLY). I fiddled a liitle with it, but it doesn't seem too useful, first of all because the internal motors (...) (28 years ago, 11-Nov-98, to lugnet.robotics)
