This disc, which could be considered the first demonstration disc for the MCA DiscoVision system by some, was not used
to any extent beyond this 1977 test pressing. Much like the more well known Consumer Demonstration Disc,
the disc includes only samples of programming material. The disc begins with the original opening bumpers for the MCA
Disco-Vision system, the only known place where the animated logo can be located. None of the other test pressings
included this bumper. The disc begins with an in depth 10 minute film on the Polaroid SX-70 camera, complete with
operating instructions and theory of operation. This is followed by a short World Wide of Sports montage from
ABC-TV accompanied with a jazzed up version of the Peter Gunn theme. The next program is a pair of hands tying
knots and displaying Three Card Monty. The "hands" section is recorded in English and Spanish and is essentially
the same component that is on the US Demo Disc, but the card trick is this time is "Follow the
Ace" rather than "Follow the Queen". Finally, we have the National Geographic program, Man: The Incredible Machine.
However, only the first 16½ minutes of the program are present, with the program simply cutting off during an
explanation of the esophagus. None of the material displayed on the disc was ever issued in any other form.
