I investigated this issue a while back an have taken apart all four of my RCX's (1.0 w. adapter, 1.0 w/o adapter, and 2 2.0's from an RIS1.5 and and RIS2.0). They all have internal voltage regulators. I've written the number down somewhere on this (...) (24 years ago, 2-Feb-02, to lugnet.robotics.rcx)

The three main outputs are Pulse Width Modulated. These are generally used for motors, but work for lights as well. The three main "inputs" can use "active" sensors that require power and can therefore be considered as outputs in their own right (...) (24 years ago, 2-Feb-02, to lugnet.robotics)

(...) Yes, but only one of 8 settings (why not all 256??? I don't understand why they limited this). Sometimes only 8 settings doesn't give you enough finesse. Matthias Jetleb (24 years ago, 2-Feb-02, to lugnet.robotics)

Hi Trevyn, From the photo you posted, it appears that you have the input and output pins of the 7805 reversed. According to the datasheet, this will probably fry the regulator. I'd recommend getting a new part before continuing, so as not to risk (...) (24 years ago, 2-Feb-02, to lugnet.robotics.rcx)
