I didn't know that about the motorolla toys!  Hmm

If I were going to use a single board CPU like the miniboard.  I
would prefer bidirectional.  Perhaps what they need to do is use
some PAL logic to save external parts and add flexibility.  Add a
BUS that includes the serial port outputs as well.  This would
add flexibility to the system.  It's too bad the 68hc11 is
expensive or it would see a LOT more use.
