Well here we go! I had to adjust the brightness and contrast in order to make out the labels. It seems the large screen TV plays only MA-2 discs. There are several contained in each box and these are "films/programs". T-Z and so forth.
MA-2 disks. Obviously better than Blue Ray which came almost 75 years earlier.
This is far before DVD but the minds who created Horizons knew we would watch "disk based" media in the near future. Tape would hit the highway and quick.
Wonderful detail. Yet another testament to those who created this amazing attraction.
