I have seen a number of post asking the same question,
What to use for external power for the RCX (ver 1.0)
I have been using RadioShack;
cat # 273 1631 - 9v 800mA AC
This transformer has the correct size jack. The output voltage
is adjustable. I cut a small length of wooden toothpick and wedge
it in the slot in the switch to make sure it doesn't accidently get
adjusted to a setting greater than 9v.
One post asked about the connector polarity. It's AC so it doesn't
matter.
I have happily run all three motor ports at once with the rated 800mA
with no problems.

| The safest bet is to use a transformer that comes with one of the LEGO train sets. I asked LEGO via email and they recommended using one of these. Here are the specs of of it: Input: 120VAC 60 Hz .12A Output: 12VAC 7 VA (...) (24 years ago, 27-Feb-01, to lugnet.robotics)
