Why led be is dimmer in pin 2 than in pin 13 ?

  // Setup the digits array

  g_digits [5] = 1 + 0 + 4 + 8 + 00 + 32 + 64;         
  g_digits [6] = 1 + 0 + 4 + 8 + 16 + 32 + 64;

  g_digits [8] = 1 + 2 + 4 + 8 + 16 + 32 + 64;
  g_digits [9] = 1 + 2 + 4 + 8 + 00 + 32 + 64;

Unless you really like typing, can I suggest that the compiler will do this stuff for you, in a much more succint manner?

byte MachineConfig[3][3] = {{5, 8, 11},
                           {6, 9, 12},
                           {7, 10, 13}};

(note also the 50% saving in RAM)
