Coin Door

     An authentic coin door really sells your cabinet.  Without it, it's just not an arcade machine.  I picked up a genuine 4-Player Coin door from HappControls loaded with Quarter Coin Mechs.  The Coin Mechs are modular and can be removed.  You can replace them with different models that accept different types of currency.  I believe they sell some that accept tokens along with quarters.

     Coin Mechs use gravity, magnets, and a bunch of other tools to tell if an inserted coin is acceptable or not.  They don't like being angled (1 or 2 degrees in one direction is acceptable, but too much of an angle and they won't work), and they don't need any power (with the exception of the switch and light).  The switch that is triggered by a falling quarter (resulting in one credit) is a larger version of the cherry micro-switches seen on all of the joysticks and buttons (it interfaces the same way as all of the buttons and joysticks with the I-Pac 4).  Easy to wire.

     Sometimes the Coin Mechs are sold separately from the Coin Door/Safe.  Mine came as one assembly.  I had to buy the coin bucket and coin bucket holder separately.

Light Bulbs:

     It actually came with four light bulbs, but they supported something like 3.3V (probably DC current).  I replaced them with four white 12V multi-LED bulbs (powered by my PC's power supply).  I can't remember which size bulbs I used, but they were designed for an automobile.  They fit right into the bulb assembly the old bulbs sat in (the old bulbs had the size number written on them).
