TMNT Data East 1991 was a interesting game for a few technical reasons.

It apparently was the first DE to have a flat hidden flap on the playfield that opened up to reveal a ball popping up mysteriously from under the playfield.
Known as the sewer or manhole pop up.

The machine also featured a full backglass still made of proper glass but had a full mirror effect from its design.
Other than the BAck Glass art featuring April with big boobs for the male market, if you look closely at a 1991 TMNT backglass it has a lot of detail & amazing art you first don't notice til u look very closely at it.

Another great feature was the use of the spinning mechanical round pizza playfield disk which also featured magnets.
I have seen some TMNT games released from factory with magnets and some without which is interesting.
The spinning Pizza decal when replaced looks great.

The game also has great audio and was the first DE from memory with the standard sized very thin Alpha Numeric type DMD that had full DMD artwork & animations instead of just numbers and the animations for their day were quite excellent.

A few people who have owned the game would know you can "clock" the game by hitting every feature/mode and then by completing "Turbo Ginzo" in a timed fast play fest which is fun but not easy.

I thought, after knowing the original TMNT DE pinball very well, plus playing the latest TMNT DVD,s which feature a lot of 2015/2016 tech in the cartoons it might sell well for home use or sited etc ?

It's cool to watch the turtles in the latest cartoons always playing a pinball machine.
Almost most episodes.
You know Pinball is back when it's in one of the latest & worlds largest cartoon series.
I am sure there is a massive pinhead or ten on the production team of the latest cartoon series cause it's no accident the pinball features every cartoon they currently do.
