Hey, all I want is to have the smallest lightest RCX and that means leaving
the batteries out of it.  I don't really care how they do the connectors.  I
even have one of those boxes with the button.  I just think power source and
power sink should be able to be separate units, especially since they now
(1.5) don't even have a provision for an adapter.  Even if you use
rechargeable batteries, you have to disassemble your robot to change them.
It just doesn't make much sense to me.  It is like having to take your car
into the shop to fill the gas tank.

No, you all missed the point.

Jack was talking about the idea of LEGO(r) providing an external NiCad • battery
pack solution to certain perceived problem (the difficulty of taking a • robot
apart in order to change the batteries in an RCX, Scout, etc.). He said:

   "we should be able to have a battery pack and just swap it"

If LEGO(r) did such a thing they would clearly implement the battery pack • as a
sealed multi-call unit, like cell phones and laptop computers do. (Why? • Because
they already *have* a normal 6-cell battery pack box, and Jack did not • suggest
the use of that box, which he obviously could have done)

So I was responding to Jack's ideas with my description of the problems of
multi-cell sealed battery packs.

And Jack, if you want to change your original idea to that of using a • battery
box, then why not suggest adding a standard LEGO(r) 4-stud electrical • connector
to the RCX and Scout whereby it could be powered by the standard LEGO(r)
battery box?
