 * LCD signals P8[46:27]
 * AUDIO signals P9[31] and P9[29:28]

 * Each cape is listed with a column to indicate if the cape uses any of the same signals as the virtual cape for each.
 * Mechanical means that the cape has been physcially plugged into a BeagleBone Black and has no clearance issues.
 * Hardware Support means that the cape will electrically work with the BeagleBone Black.
 * Software Support means that the cape is supported in the bootable linux distribution image that ships with the BeagleBone Black.
