Trivia...

A total of 11,725 ST:TNG games were produced

Prototype

There were 200 ST:TNG 'prototype' models produced. These test models were released approximately 2 months before the regular production games were released

These prototypes have three differences from regular production games:

Artwork on backbox sides is silkscreened onto the backbox surface. Regular production games had a silkscreened decal applied. The edges of the decal are obvious on production games.

Red lenses on the gun turrets on the playfield are domed. Regular production games had a flat opaque lens inside the gun turret. Here's a picture of the promo ones.

Prototype	Production

Test model games used special high-power FL-17636 flipper coils on all three flippers. Star Trek test models were the only pinballs ever produced by Williams that used these coils. Regular production games used the lower powered FL-11629 coils.
