I'm still not clear on exactly what the RCX enternal-power
input will accept. Can anyone tell us what the internals
really are??
If I view the RCX power connector closely, I read:
9-12V~ (nine dash one two Vee tilde)
I would interpret that to mean:
"Nine to Twelve Volts AC"
Can anyone confirm this??
Also, will it 'accept' 9 to 12 volts DC because of
internal diodes??
I understand many of you are using "Wall Wart"
supplies that put out 9 volts DC and they work OK.
Is that true??
Sorry, want to get this straight!!!

The conversion to AC also requires a sufficiently large (...) (25 years ago, 12-Sep-99, to lugnet.robotics.rcx)

| 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)
