Entropy International coin doors

Entropy International coin doors appeared on Williams games from around 1988 until the end of production. There are two types: two/three slot with one coin return, and two-slot-two-return.

Entropy doors usually have a distinctive diagonal “QUARTERS” insert (but I’ve seen this on other makes, too).

Entropy doors always have orange inserts.

Some parts are available from Pinball Life.
