              It also appears that the reason the Intellivision provides two copies of the outputs for BC1, BC2 and BDIR is to avoid vias on standard cartridges.  (Vias are connections between the top and bottom sides of a circuit board.)  It is impossible to reflect 3 control lines as standard cartridges do and simultaneously use those lines on the cartridge without at least two vias.  Avoiding vias reduces production costs.
