unless there are another versions of the H8 that have more
inputs/outputs (?)

I didn't know it was processor limited.  Maybe they can do some sort of
multiplexing.  (At least for inputs)  That way they could get 2 or more
in the space of one.  But you do see the need for more outputs right?  I
would LOVE 'em. :)

Hehe, I have never seen that one.

That sounds too good to be true :)

I heard they couldn't have the radio link in the RCX becuase of FCC
regulations.  I agree that radio is MUCH better than this line-of-sight
IR.
