No one has answered your Question fully so here goes.
The RCX with the power Adapter port is the 'old' one. It's power port can take the
following:
AC or DC (It doesn't matter what direction) AC is a little easier on the RCX as it
uses both sides of the 'bridge rectifier'. There have been reports of people
blowing one side of the bridge when using too many amps.
Amps should not exceed 2 amps (2000 Mili Amps) but I've used it with 200 ma's for
projects that only need one motor on low etc.
Other then that it's exactly the same as the 1.5 brick.
From what I remember the 2.0 brick will have the power adapter back in. YAY!
I use an RC 9volt pack on one of my RCX's. IT can also 'whine' when it's low and
ask for a recharge.
Hope that helps.
