I saw someone mention that "MBI" at the start of the Boards video stood for "Moody Bible Institute", which would make sense given the voiceover on the initial VHS tapes. This is accompanied by roman numerals for 1979.

I found this MBI "Arch Yearbook" for 1979. I've not cross-checked it intensively, but based on a cursory look, I'm pretty sure a few of the images found in "Prophecy At 1420 mhz" can be found in here.
