well done Leon. Some good info there.   I can add a first for a machine that is not on there.

FIRST machine with a opening flap on the playfield that shoots a ball onto the playfield from a hidden trapdoor, TEENAGE MUTANT NINJA TURTLES - DATA EAST 1991 , with its sewer hole. AND TMNT was the first Data East machine to incorporate DMD style graphics with alpha numeric graphics on a single display. (Bugs Bunny was the first in 1990 to do a dmd style batch of graphics with alpha numerics on a double (2 x singles side by side) on a display for a Bally I believe.
