Hello, I think I remember a post about using a 9V adaptor to power some version of the RCX during testing, but could not find it on the website. Do I remember this right? Thanks! -cmr (23 years ago, 6-Sep-01, to lugnet.robotics)

RCX 1.0 is the only unit that has a 9 volt adapter port. You can use an ac or dc 9volt supply on this. The power supply for the trains is suitable. -- Bob Fay rfay@we.mediaone.net The Shop (URL) Radu" <lego-robotics@crynwr.com> wrote in message (...) (23 years ago, 6-Sep-01, to lugnet.robotics)

(...) However many people had problems when using DC power regularly - probably becuase it burned out one half of the rectifier. I'd advise using a 10V AC adapter if you're gonna be using it regularly. (Of course you've gotta get a RCX 1.0 first!!) (...) (23 years ago, 7-Sep-01, to lugnet.robotics)

I just picked up a 1.0 set, and I looked through the documentation for info on the type of adapter to use. There appears to be nothing at all in any of the manuals. So I'm looking at the RCX itself. It says "9-12V~". Is the "~" supposed to indicate (...) (22 years ago, 31-Aug-02, to lugnet.robotics)

I use Radio Shack 273-1631. I have a number of these and I have been using them for a couple of years. These devices have a voltage selector switch which I set to 9v. In fact, I wedge a short length of wooden tooth-pick in the switch slot to avoid (...) (22 years ago, 31-Aug-02, to lugnet.robotics)

Your comment intrigued me into checking. I grabbed a couple of transformers and checked them (with a 4 1/2 digit true rms meter). Off load (open circuit) one reads 10.4v a/c, the other 10.9v a/c. That is well within Lego's 9 - 12v a/c spec. JB (...) (22 years ago, 31-Aug-02, to lugnet.robotics)

Thanks to everyone for the responses. I feel a little better about actually using the port now. I was concerned because of the speculation a while back regarding why the port was removed, and I have no intention of burning out the unit. -- Tony (...) (22 years ago, 3-Sep-02, to lugnet.robotics)
