This is an idea that a friend who also has the Tweety Board came up
with, but I haven't had any contact with him, so my question goes up
here.

I'm wondering if there is a way so that I can split one of the
channels in half and then combine each half with the other two
channels.  To make things more clear let me give an example.

In installing the TB, it is suggested to combine channels A & C to one
channel and B to the other.  No that's all well and good, but is not
exactly balanced.

I figured this.  Could you split line B and combine A & B for one
channel and B & C for the other channel.  Now I know that your basic
every-day splitter would give me the effect of combining all the
channels togther, so that won't work.  What I need to know is what
should I put inline to make line B (or A or C) split into two one-way
lines?

Thanks in advance,

Dom
