As far as i know - NONE of the machines available use anything other than DMD, but this is typical Stern, they never were ground breakers when they started out and never will be.
Pinballs get bigger - the workings get smaller - go figure that one!
Instead of translite - you could have the whole backbox as a flat screen with video modes of ACTUAL film being trigered by a sequence of switches. Aint difficult to do.
Graphic cards could be bought for more mature versions of a game etc.
Flat screen does have to be as big as standard backbox - no reason why the boards cant be housed in the cabinet - all those looms, so bloody dated!
