I made addon that adds interaction with bundled cable from RedLogic via a peripheral block.
Downloads: 1.6.2 1.5.2
Methods:
setOutput(colors) analog redstone.setBundledOutput(side, colors), but it supplies a signal to all sides.
getInput() analog redstone.getBundledInput(side), but it receives a signal from all sides.
Example:
expander = peripheral.wrap("right")
expander.setOutput(255)
