I use Radio Shack part number 273-1631. This has a selector switch which you should set to 9v for the RCX. The output from this particular transformer seems to be modestly stable, only rising to 10.5 volts or so off-load. This stays well within the (...) (22 years ago, 2-Nov-02, to lugnet.robotics.rcx)

Any 12V supply will do. It should be capable of at least 600mA. The Lego train transformers work well if you have one. Otherwise, any 12V transformer of any polarity will do (or even AC as the Lego train transformer supplies). Matthias Jetleb (22 years ago, 2-Nov-02, to lugnet.robotics.rcx)

|

I have a RCX 1.0. And while it has a power plug, I don't have a wall wart. Is there a specific part I need from Lego, or will a "generic" wall wart do? And if so, what are the parameters (voltage, current) I need to look for? Thanks! (22 years ago, 2-Nov-02, to lugnet.robotics.rcx)

I'm trying to use "TOWERAPI.DLL" to directly setup the USB tower drivers in a Windows C++ program using Microsoft's Visual Studio.
