The RCX will work off about 7volts as long as you don't use too many motors.

If you have RCX 1.0 with power adapter port you can use any 9~12 volt adapter.
The lego train ones work great. AC or DC.
For the RCX 1.5, scout and CYBERMASTER I've been working on an adapter for it.
Basically it will have a relay onboard with polarity correction and overload
protection.
You attach it to the battery polls. (Leaving the batteries in) When power is
detected it switches over. When power is lost it transfers back to internal
batteries.
It won't be ready for another month though...
