I'm trying to make sense of this and from what I'm thinking is that the OP is having a time of his life and after looking at the flyer for back to the future he believes gary stern is doc brown and has built a time machine out of a delorean. With that in mind OP thinks post 2000s gary went back in time to the 70s/early 80s to tell young gary about the stern dmd logo image (resized).jpg which was the reasoning behind the original stern logo which is seen in the first picture on the flight 2000. He then thinks that was the reason why data east (stern) was the first to have dmd's in their pinball machines.

Wow that was a mouthful to understand

However the original logo is based on incandescent lamp signs

I know you were joking I was just going to play along and believe you were actually crazy
