One thing you might want to be careful of: I read before that people have
"blown up" the input jack (though not the RCX) by using adapters that can
provide too much current. I believe anything up to an amp (1000 mA) is
safe. Again, is there an official spec on this?

Yes, that's fine, typically when you plug an external power source in, it
just bypasses the batteries.
