Advanced Interface (Scomp Link) for Mark III or Mark IV Refresh

Complete video instructions in the .pdf file.    It has better performance and a longer extension.  Additionally it has been optimized for the Mark III, Mark IV and Com8 frames.  This will fit in any tool bay in the Mark IV.
See https://www.facebook.com/share/g/17XfjR9nK7/ for some instructions on the build.  However, read the instructions for the most up-to-date information.  I'll get around to updating the video eventually.
