Gottlieb came out with this game in 1981.

There were 8,774 units produced, IPDB reports.

Notable, of course, for the backbox animation. The spinning disc produces a cool effect– when it’s still working. We almost never find them operable in machines anymore.

We fixed a few things mechanically, and did a few touchups on the playfield.

No LEDs in this one.

The other notable feature–the sunken second playfield. IPDB reports that Black Hole was the first machine to offer a lower playfield sloped away from the player with the flippers at the backbox end.
