This uses the same technique as I did when I adapted this one for the Triton of making the lines pullups that you pull down so I can modify my extended board to do the same thing. If and when we get a larger version of this with more opto's then it will be another machine in its armoury if I can get it working. If not then I will build one of Phil's devices.
