Trailer for the original MPI?

[Amian]

Just curious if anyone has the promotional material for the original from 1980... I found this one, but it's only a 15 second spot. https://www.youtube.com/watch?v=ha4s-wGe47Y

Here is another early commercial.

I wanted to get a sense of how the early episodes were presented in the equivalent of today's longer trailers.
