The viewport emulator is now installed on the HAM6 north door to facilitate ISC beam alignments.  We needed to clock the o-ring protectors 3-4 bolt holes (don't remember which) clockwise to get the holes lined up so the emulator would bolt on straight (LHO WP 7322.  We initially thought the wrong protectors were installed, turned out it was a simple mispositioning when they were intially installed.  This also closes WP 7322.).
