MJ,
The RCX itself does not need a lot of power. However, if you're going to run
2 motors off each output port (a total of 6), 200 mA won't be enough. I
expect the motors to draw at least 100 mA each. Even more when stalled.
Maximum power to be drawn from a 200 mA/9V power supply is 1.8 Watts. Not a
lot.
I use an 830 mA socket type AC adapter, which cost me the equivalent of
about US$ 8.
On the other hand, you won't blow up your RCX by using a small power supply,
so don't be afraid to experiment.
You might burn out the adapter though if it's not properly fused (fire
hazard!).
Good luck,
Arjen

| The best way to avoid high current running thru the brick is to control a small red motor which drives one of the polarity switches which is hooked up to a battery pack and that in turn runs the main motors. We had this problem at the LEGO (...) (25 years ago, 5-Sep-99, to lugnet.robotics.rcx)
