I worked on the chroma circuits for this device, so here are a few notes:
I'm not familiar with that reel, and unfortunately it's monochrome. Whoever gets this should start a search for a color reel too.
some things I recall:
The color process used is interesting, involving a half-frequency chroma subcarrier and 1/4 frequency reference pilot added together and recorded on the "right" side of the film, with the luminance as a recognizable image on the "left" side. The monochrome programs have luminance on both left and right. I developed filters for the chroma and pilot that could be tuned to track phase within 1 degree with a frequency deviation (caused by scanning non-linearity) of as much as 10%.
The pushbuttons on this deck are mechanically coupled to the mechanism, and there is not much leverage available - takes a strong thumb to operate. The cartridge has a pop-up top that releases a stiff plastic leader into the mechanism. The leader is PUSHED into the film path and onto the take up reel by the rotation of the cartridge. This always works up to the point that the leader reaches the take up reel. The original design had frequent threading failures (the leader would trigger play mode but not get captured by the take-up fingers), which were fixed by moving the trigger point (where the leader trips the mechanism from threading mode to play mode, engaging the capstain) further around the take-up reel. This meant the fingers could miss once without triggering play mode, and make a capture on the second rev.
The film uses sync windows down the center between the two images. These are illuminated by a light pipe in the film gate. It was supposedly a smart idea to have continuously running film with no pull down mechanism or sprockets to tear. but it turned out that this center track was an extremely bad wear point. It took a combination of heavy silicone lubrication on the film and a special gate finish to prevent the sync track from wearing out. The chief mechanical engineer at Motorola got patents and an award from the zinc casting industry for his development of the finishing technique.
Despite what the ad says, it does not use X-ray technology. There may be an X-Ray warning for the flying spot tube, which uses a very-short-persistence violet-blue phosphor. Pickup is via a pair of matched lenses, plastic light pipes, and two ordinary 931-type photomultiplier tubes.
