 | | Re: Wall wart for RCX 1.0
|
| 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)
