I went to a pinball gig in South Florida this past weekend because in the games listed were a Centaur and Fathom.
As soon as they opened Sat. I was looking for both of those games. They were side by side . . . sweet. The Centaur was set to 3 balls and didn't quite have the action your game has but it was nice seeing & playing. Couldn't put my initials on the game but had the high score when I left. I also agree the multi-ball options were way ahead of their time.

Enjoyed your video . . . more so at the 8+ minute with your 3 ball play and a little later with 4 or 5 ball play . . . sorry, I lost count (my bad). Please share more videos in the future.
